1. Wildlife Conservation Essay
They are responsible for cleaning the air most living creatures breath, they give humans and animals
material to build homes and buildings with, they help keep the dirt in place, and, among many other
uses, they gave humans the material that people use every day, paper. They do all this for humans,
and all they need in return is for their young to be planted. If you have not guessed by now, this is
describing trees. It is vital for humans to maintain not only the trees population, but also the
population of all wildlife. Wildlife conservation is important because regulates wildlife population,
helps balance the ecosystem, and maintains the natural beauty for future generations. People mostly

Also, when the deer population is too high, farmers crops become damaged by the deer, as well as
there are more deer killings by car ("Deer" par. 1–10). It is important to keep track of an animals
population in order to make sure that the negative side affects do not occur. Sometimes it means
keeping one species in its own habitat and preventing it from expanding into habitats that are not
its own. Species who manage to do this are called invasive species. Species such as the Lionfish.
Lionfish are not a native species to the Atlantic Ocean. They are a venomous, fast reproducing fish
that are aggressive eaters and will eat almost anything in copious amounts. They eat so much that
they will actual become obese and contract liver diseases. They have no know predators, besides
humans. Because they have no predators, once introduced to a reef, they can wipe out 90% of it.
"The lionfish invasion is probably the worst environmental disaster the Atlantic will ever face" said
Graham Maddocks, president and founder of Ocean Support Foundation ("Lionfish" Par. 3). Lionfish
are especially dangerous to ecosystems, because the native aquatic life–forms do not have a natural
instinct to be wary of the lionfish. Some may wonder, "how did the lionfish become introduced to
the Atlantic ocean?". Well, Florida pet owners are to blame. Lionfish are most known for their
beauty, which makes them valuable as pets. However, they are violent fish and tend to attack and
kill other fish in the

2. Wildlife Tourism
Introduction
This portfolio will first of all be discussing the topic wildlife tourism, which can be enjoyable for
tourists. They may enjoy purely watching wildlife whilst travelling to maybe learn some facts about
wildlife (non–consumptive wildlife). Or, conversely, they may wish to be much more involved in
some form of touching with the animals, or this even may involve the capturing or killing of animals
(consumptive wildlife). Both of these will be critically examined below and examples of both will
be given. The reasons as to why people like both consumptive and non–consumptive wildlife make
this topic exciting and want to discover whether this type of tourism has more of a positive or
negative effect on society. Wildlife tourism can be defined as "tourism undertaken to view and/or
encounter wildlife. It can take place in a range of settings, from captive to semi–captive, to in the
wild, and it encompasses a variety of interactions from passive observation to feeding and/or
touching the species viewed"(Reynolds, 2001).
Trophy Hunting
Trophy hunting is a common type of consumptive wildlife and is a profitable business. For
example, the dentist Walter Palmer, who recently killed the popular Cecil the Lion from
Zimbabwe's Hwange National Park, was reportedly paid $50,000 (Costa–Roberts, 2015). Despite the
barbarity of the killing, skinning and beheading of Cecil, Emma Fredieu claims that "the relationship
between trophy hunting, wildlife conservation, and

3. Pollution Effect On Wildlife
Everyday humans spit gum on sidewalks, use gas to commute to work, throw trash on the ground,
never managing to clean up after themselves. Pollution, intentional or not, affects animals all
around the world. Over the last 40 years, wildlife populations have fallen by 58% ("World Wildlife
'Falls by 58% in 40 Years'"). This percentage will continue to increase if the world does not take
action. Pollution's negative effect on wildlife can be solved by using clean energy and properly
disposing of waste. Pollution affecting wildlife has harmed many animals in their natural habitat.
This occurs because of human actions on the environment. Pollution is in every aspect of animals
lives. Including, the air, water, and soil they need to live by. These problems continue to grow
each and everyday. BBC News article "World wildlife 'falls by 58% in 40 years," is a company
responsible for gathering and broadcasting news and current affairs, suggests that, "Global wildlife
populations have fallen by 58% since 1970" (Morelle). If pollution continues, these numbers will
continue to increase. Wildlife populations could become extinct if no actions are taken to improve
the environment. Air pollution is one of the worst types of pollution affecting the world today. The
forest fires, factories emitting smoke, the burning of fuel and other materials, and the use of
chemicals, all contribute to harming the air animals need to survive on. Plants and trees take in these
bad substances and produce

4. Descriptive Essay : Wild Animal Tour
It was a clear day in the jungle. Wild Animal Tour's, the number one safari company in west Africa,
had at least thirty tours planned for the day. Most of the customers were either from America or
Europe. The year was 1988. Ricardo, an adopted baby from Africa, was on vacation with his mother,
Mindy. They decided that to top off their month in Africa, a safari would be perfect. They found out
about Wild Animal Tour's from a local who said that were 'the best around!" they excitedly hopped
on the tour bus. The guide, an old man named Ode, voiced over the radio the rules and expectations
of the tour. Everyone was on the tip of their seat, ready to see some wildlife. After going over
everything Ode started up the off–road bus and headed down...show more content...
It was a male lion. Most people were smiling and screaming in excitement. The lion started chasing
the wildebeests, which all started heading the tourists direction. The smiles slowly turned to
confusion and question. Ricardo was a decent ways a away from everyone else, on the other side of
the road coming out to the plane. He was about to head back to the bus when Ode came balrin
past, the wilda beasts all went around him, like water around a rock. Ricardo couldn 't get to
everyone else, the wilda beasts were in his way. At this point he wasn 't paying attention to where
the lion was and was just trying to get back to the group, there was no way. All at once he turned
around to see the lion five feet away from him. They both were frozen for a second before the lion
growled a little and ricardo dashed into the woods. He ran as fast as he possibly could. Jumping
over logs, Slipping through vines, hurdling rocks.. The lion chased him until Ricardo was almost
out of breath. Ricardo needed to find a way to hide from the lion. He saw a tree with hundreds of
vines hanging down, he slithered through them till he got to the base of the tree, there was a thick
wall of vines shielding him from being seen. He sat there and waited. After an hour of waiting he
realized the lion had probably lost him and went back to the wildebeests. He came out from behind
the vines. He looked around to see jungle. Jungle ass far as he could see. He didn

5. The World Wildlife Fund ( Wwf ) Essay
Media Audit The World Wildlife Fund (WWF) has launched several campaigns in the past few
years, all focused on several endangered species and natural habitats to try and save the extinction of
the planet's biodiversity. Although WWF has had success in their campaigns and received a plethora
of positive feedback, the non–profit organization has also received negative comments in the media.
Strengths Goals. WWF's work has evolved from saving species and lands to addressing the larger
global threats and forces that impact them. Recognizing that the problems facing the planet are
increasingly more urgent and complex, they have refined the way in which they work around a new,
ambitious strategy. Their new strategy puts people at the center and organizes their goals around six
key areas: marine, forests, wildlife, freshwater, climate, and food. By linking those six areas in an
integrated approach, they receive better leverage for their unique assets and direct all the fund's
resources to protecting vulnerable places, species, and communities worldwide. In the WWF's
Manifesto campaign, the organization states that even the most ordinary people have an impact.
From the government to large corporations, WWF demonstrates that with the initiative of one person
any goal can be achieved. An article from Spiegel, a British–based magazine, said: "Even with the
littlest impact from someone is still an impact, and WWF finally recognizes that it only takes one

6. Wildlife Endangerment Due to Human Intervention in Nature
"The driving force behind today's alarming decline in species is the destruction, degradation and
fragmentation of habitat due to our increasing human population and wasteful consumption of
resources."1 Everyday wildlife is forced to seek refuge in very remote, small areas. As the human
population increases, land that was once inhabited by wildlife is urbanized to suit human needs. In
other words, the land available for wildlife to survive on keeps diminishing. As houses and roads are
constructed, forest are cut down and cleared; consequently eliminating the natural habitats of
wildlife. This causes animals to migrate to new areas and seek refuge. Under certain, harsh...show

Humans have a brain that has the capability of reasoning and thinking, which allows them to
understand the concept of technology. Animals on the other hand do not have the ability to reason.
Since animals do not realize that roads and highways are potentially dangerous, they are often
killed. Every year thousands of animals are killed by cars because their homes are destroyed. Even
though these killings are accidental, they still decrease the wildlife population.
"Road building associated with agriculture, logging, mining and urban development seriously
impacts ecosystems in a number of ways."2 Dirt roads are usually built through forests, causing
erosion and therefore degrading the quality of water in streams.3 Paved roads, unlike dirt roads, are
not permeable.4 They cause water to drain elsewhere, often polluted with gasoline, oil, and lead off
the road.5 "In addition, when roads cut through an ecosystem, further habitat degradation and
fragmentation results."6 The polluted water may cause animals to become very ill, and sometimes
they die. Even though roads seem harmless, they are very dangerous to nature. Building roads
decreases the area that wildlife has to live. They end up inbreeding because they have no place left
to go. This is happening to the Florida panther now. Due to lack of land, the panther is forced to
mate within its own area

7. The Effect Of Urbanization On Wildlife
In modern day urban settings, it is not uncommon to walk outside and experience Madagascar right
in the city parks. OK, maybe not quite Madagascar yet, but cities are getting there. The wildlife that
used to live out in the wild are now migrating into urban areas because there are no resources left for
them in their original homes. The problem is humans. Humans have taken over the resources,
homes, and economies that animals need to survive, so they are forced to come closer and closer to
humans. The movement caused by this is creating many problems between humans and the animals
that are forced to move. Urban wildlife is beginning to cause damage to the environment and needs
to be stopped.
The effect that urbanization has on wildlife is...show more content...
One of the causes of fear loss is caused by animals being too closely associated with the millions of
humans that surround them on a daily basis. The animals are forced to reside in human habitat
because they have nowhere else to live. The closeness can cause alterations and "some urban
animals trade personal space for the convenience of the city" (Soniak). Species continue to be made
to live side by side to humans and breathe the exact same air that they do. They practically share
homes with humans now because of the lack of space and the excessive populations of urban
wildlife. What used to be considered taboo is presently different because "the relationship between
humans and large predators is changing" (Mahoney). Large predators who lose their fears and
approach humans in search for food or water are put in danger because humans misunderstand the
animals and what they are trying to tell them. They may view a harmless approach for food as a
murder spree targeted straight at them.
Another problem that follows urbanization is the harmony between humans and animals that has
been around for years is now being disturbed. The amount of wildlife deaths in urban cities is rising
as more human populations expand and grow. Some threats to urban wildlife include: habitat loss,
light and noise pollution, invasive species, chemical runoff/ pollution and habitat fragmentation. For

9. The dynamic natural environment and abundant wildlife are the most prominent features of the
African continent. Due to its wide variety of biomes ranging from tropical forests to arid deserts,
Africa consists of bountiful wildlife diversity. However, because of environmentally harmful human
interactions, the variety of biomes is shrinking to all–time lows, which causes wildlife to die out.
These detrimental human interactions, particularly livestock overgrazing and desertification, occur
partly because the native people who depend on the land for daily life do not realize the potential
benefits of wildlife and the unsustainability of their current ways. Poaching for horns and other
valuable animal parts has also contributed to the...show more content...
Herding allowed people to extract previously unobtainable nutrients from their environment. Since
humans could not directly digest the grasses that existed in the savannas, the only way for them to
take in the nutrients was to use cattle, which are capable of grazing or consuming grass, to convert it
into edible forms. By consuming the milk and meat that the cattle produced the people were able to
fully exploit the resources available. This pastoralist lifestyle was symbiotic with the agriculturalist
lifestyle because the two communities traded goods with each other to maintain healthy diets.
Therefore, many civilizations, like Mapungubwe in southern Africa, depended on the mutual
relationship between humans and domestic animals to survive. This system was widely accepted
due to its effectiveness and eventually became ingrained in African social and economic life.
However, because of the rapid increase in population in Africa over the last several centuries has
led to severe overgrazing, which occurs when the grass doesn't have sufficient time to recover before
being consumed. This has led to desertification, one of the major causes of the decrease in African
wildlife populations. (Child Physical Environment, 2013)
Desertification is a process that degrades the natural environment to an unproductive state that cannot
support the native wildlife communities. More specifically, desertification involves land degradation

diverse species of birds, mammals and other animals. In India there are around 531 wildlife
sanctuaries. Among these wildlife sanctuaries, Project Tiger in India governs 28 Tiger Reserves
and they hold special significance in the preservation of tiger. Interestingly, some of the wildlife
sanctuaries are specifically named as Bird Sanctuary, such as Keoladeo Ghana National Park
before they attained the status of National Park. Several National Parks of the country were
formerly wildlife sanctuaries. Wildlife sanctuaries in India cover near about 4.5 percent of the

The crucial role of the Philippine government on wildlife conservation
Thesis Statement: The Wildlife Resources Conservation and Protection Act (R.A. 9174) of the
Philippines should be prioritized and reinstated because of its failure to serve its purpose in the past,
its ability to lessen the rising human–caused extinction rates, and its possible influence in restoring
and promoting action regarding wildlife conservation.
The loss of biodiversity and wildlife is becoming a larger problem every year yet most people
disregard it and its consequences. Wildlife plays a big part in maintaining environmental support to
human life––serving as a source of food, contributing to agriculture, aiding in medical research, and
many more. The continued erosion of ecosystem and species diversity threatens the progress to a
sustainable society and lessens the chances of stable environmental conditions in the future. As the
effects of human actions become more damaging to the environment and the situation of wildlife

"We call them dumb animals, and so they are, for they cannot tell us how they feel, but they do not
suffer less because they have no words" (Anna Sewell). There is undeniable evidence that animals
are being affected by climate change. Even though the effects are difficult to measure, there are
many different ways animals are being affected. With the loss of predator and prey species it affects
the life cycles in the food chain. The earth's climate change causes habitats such as snow, ice, or
forest areas to alter, resulting in loss of habitat and food accessibility as well as causing extinction.

the collection of greenhouse gases, carbon...show more content...
While floods cause pollution in water that can damage plants and habitat it also washes away
nutrients that are important for plant growth (Arctic Climate Change). Too little water such as
during a drought can cause plant and animal life to die, altering the food chain and ruining the
pattern.
Habitat loss is one of the most evident effects of climate change on animals. Forests, as well as
deserts support many forms of life. It is the home of insects and animals like bears, and birds. If
forests will be cleared out for the development of land for families, business and farming purposes,
animals will loose their homes and food. Because of deforestation, many of the trees and the other
plants that provide food to the herbivorous animals will get extinct at a faster speed. Droughts
caused by global warming could dry up 90 percent of central U.S. wetlands, eliminating essential
breeding habitat for ducks, geese and other traveling species (National Wildlife Federation).
Climate change is the main reason to wildlife's survival and putting natural resources in danger.
The change in temperature caused by global warming has many effects on the habitats of animals.
The melting ice will cause the loss of habitat for species such as the polar bears, penguins, and

A wildfire is any instance of uncontrolled burning in grasslands, brush, or woodlands. Wildfires
destroy property and valuable natural resources, and may threaten the lives of people and animals.
Wildfires can occur at any time of the year, but usually occur during hot, dry weather. Wildfires are
usually signaled by dense smoke which may fill the air for miles around. The National Weather
Service, U.S. Forest Service, and State forestry agencies combine to give wildfire probability
forecasts. Local radio and television stations broadcast information and warnings on local fire
conditions. Wildfires pose an increasing threat to the residential United States. In 1987, 53,000 fires
consumed more than two million acres. By October 1988, almost...show more content...
On the actual day of the fire, the fire planners will again check such conditions as wind and
moisture content in the vegetation. The wind direction will determine where the fire is started. Fire
crews start the burn with a device called a drip torch. A drip torch is a can of fuel with a
flame–carrying wick at the end. When the crewmember tilts the wick toward the ground, a flame
streams out and ignites the vegetation. Most of the effort that goes into a prescribed fire is making
sure that it is contained in the boundaries set for the fire. Firefighters and fire suppression equipment
are near the site if the fire grows out of control (www.nps.gov/wica/fir–why.html, pgs. 1–3).
While not all the effects of prescribed burns are known some are very evident. The first of these
common effects is that vegetation and fallen dead material are burned creating an open forest floor.
This eliminates any fuel that could contribute to a high intensity fire in the future. When the fire
burns the organic material in the forest, nutrient rich ash is left behind. When the first rain comes,
the nutrients in the ash dissolve into the soil for the new plants to use. This process is called
nutrient recycling. These nutrients left in the soil are a good source of food for the young plants
that will begin to grow back. Another outcome of prescribed fire is that new growth begins
immediately after the fires have been extinguished. Within

The categories according to the IUCN are "Extinct (EX) when there is no reasonable doubt that
the last individual has died. A taxon is presumed extinct when exhaustive surveys in known and/or
expected habitat. Extinct in the wild (EW) is when it is known only to survive in cultivation, in
captivity or as a naturalized population. Critically endangered (CE) considered to be facing an
extremely high risk of extinction in the wild. Endangered (EN), considered to be facing a very high
risk of extinction in the wild. Vulnerable (VU) is when an observed, estimated, inferred or suspected
population size reduction of в‰ Ґ 50% over the last 10 years or three generations, whichever is the
longer. Near threatened (NT) when it has been evaluated against the criteria but does not qualify
for Critically Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely
to qualify for a threatened category in the near future. Least concern (LC) is when it has been
evaluated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable
or Near Threatened. Widespread and abundant species are included in this category." The last two

Pollution is killing and harming wildlife in the united states and all around the world. Oil spills
are very bad and have huge affects on wildlife, toxic metals like lead kill many animals each year,
pesticides are thought to be good for crops but have bad affects on wildlife. All these factors have

Some of these impacts include decreased resistance to disease, neurological damage, impaired
reproduction, and birth defects. Toxic metals can have a huge effect on wildlife. Agricultural
practices can spread toxic metals and hurt wildlife. Toxic metals that are in fertilizers can affect
wildlife. Another way of agriculture hurting wildlife is irrigation which can leach toxic
substances from the soil. When these substances are leached from the soil they are exposed to
wildlife. Lead is a very dangerous metal. Lead is very poisonous and can harm wildlife and even kill
them. In 1923 the lead began to be used as a anti–knock agent in gasoline. The use of lead in
gasoline released a lot of lead into the air from the vehicle exhaust and contaminated water and
land around roadways. The wildlife living near the road showed to have an increased amount of
lead in their system. The effects of lead on the neurological development of humans is the primary
reason that the use of leaded gasoline has been curtailed dramatically in the last 20 years(Davis).
Lead in ammunition is not fair to shoot animals with because it can poison their bloodstream.
Millions of pounds of lead from hunting and shooting guns ends up in the environment each year.
Lead for waterfowl hunting was banned in 1991 but is still used in other types of hunting. A
problem with hunting other game with lead is that the animal could die and scavengers like eagles
could eat the dead
