2. 10 Major Current Environmental Problems

3. Pollution ; Air, Soil, Water : Causes of water pollution : Oil spill, acid rain, chemical pollution from industries, flinging the litter causes of air pollution : toxic and chemical gases release by industries Ignition of fossil fuels Causes of soil pollution : Industrial waste that deprive the soil from fertility

4. Protective Measures Keep car, boat, and other engines properly tuned. Carpool, use public transportation, bike, or walk whenever possible. Be sure your tires are properly inflated. Develop forests in new areas for increasing the soil fertility and formation.  Use of correct farming techniques Recycling of Waste before disposal Use of organic  fertilizers  instead of chemical fertilizers and pesticides.   Proper sewage treatment and management. Abstain from flushing contaminated liquids, pills, drugs, or medications down the drain.

5. 2. Deforestation : Termination of forest at massive level is called deforestation. Effects of deforestation : Deforestation is the cause of rising temperature of the earth. The reason of Low rainfall. Natural source that sinks carbon dioxide and release oxygen that human beings breath in. Statistical index box shows that forests are spread over 30 percent of land. Overpopulation demands more food, shelter, clothes. This simply act is performing just to get valuable timber and residential areas. Unconsciously, unknowingly, they are flaming their own planet.

6. Protective Measures Go paperless. Recycle and buy recycled products. Eat vegetarian meals as often as possible. Ban on cutting of trees and new trees and planting more. Support the products of companies that are committed to reducing deforestation. Raise awareness in your circle and in your community. Buy recycled products and then recycle them again.

7. 3. Overpopulation : Population of the planet earth is reaching unsustainable level. Scarcity of natural resources e.g. potable water, fuels and food Exodus toward cities and inclination is diverting from agriculture to industrial business. To produce gross quantity of food, farmers use chemical fertilizers, pesticides and insecticides that ultimately destruct the natural habitat of animals. Overpopulation, one of the crucial environmental problem prevailing throughout the world.

8. Protective Measures Restrict child marriage and raise the legal age of marriage (minimum 18 years). Generously fund family planning programs. Embrace rather than fight aging and shrinking societies. Greatly increase the amount of foreign aid going to family planning. Eradicate gender bias from law, economic opportunity, health, and culture. Giving tax breaks to families with a low amount of children will encourage a lower amount of births. 

9. 4. Natural Resource Depletion : Another crucial environmental problem Fossil fuels consumption results in omission of green house gases. That is one of the most major causes of global warming and climate change. Precaution: Several renewable resources of energy are being introduced globally. E.g. Solar, wind, geo thermal energy.

10. Protective Measures Controlling Deforestation Reducing oil, mineral, and material consumption Protecting wetlands and coastal ecosystems More exploration and use of renewable sources of energy Sensitization and awareness creation

11. 5. Waste disposal : Over consumption of resources and creation of plastic are creating a global crisis of waste disposal. Developed countries are notorious for producing excessive waste or garbage and dump that waste in the ocean to get rid of it. That is destroying aquatic habitat for both plants and animals. Many Countries prefer to burry that plastic, electronic, and non degradable waste inside the land to get rid of it. That tremendously destroy the fertility of land and make it barren.

12. Protective Measures Ditch the plastic bags. Make a meal plan. Start relying on reusable containers. Start composting. Learn to repair rather than discard. Stop using disposable plates. Purchase fruits and vegetables that are not pre-packaged in containers and plastics.

13. 6. Climate Change : It is occurring due to the increase of temperature of earth that is caused by burning of fossil fuels and omission of other harmful gases by industries and kilns etc. Rising temperature is not limited to melting of polar ice change in seasons and occurrence of new diseases. It causes floods, desertification, land sliding and overall weather scenario.

14. Protective Measures  Make Your Commute Green Get politically active and vote Recycle Encourage the use of renewable energies Consume less, waste less, enjoy life more Start a climate conversation

15. 7. Loss of Biodiversity : Human activities is leading to the extinction of species and habitat and loss of biodiversity. Eco-systems took million of years to be perfect are in danger when any species population is devastating.

16. Protective Measures Nature preserves Reducing amount of invasive species  Habitat restoration Captive breeding and seed banks Reduce climate change Purchase sustainable products Sustainable living Education

17. 8. Urban Sprawl : It refers to the migration of the people with high density from rural areas to urban ones. That causes overexpansion of cities. It becomes that cause of: Land degradation Increase traffic Environment issues Health issues More litter More consumption of fossil fuels Challenging the carrying capacity and gradually moving toward destruction.

18. Protective Measures New Urbanism Invest in Better Public Transportation Providing a Sense of Place Preserve Natural Resources Revitalizing Cities and Older Towns

19. 9. Global warming : Causes of Global Warming : Emission of green house gases like carbon dioxide, methane, nitrous oxide etc. into the atmosphere. Transportation: Fuels from transports (E.g. LPG, Kerosene, fuel oil) Industrial Processes: Manufacture of cement, steel, aluminum etc. Agriculture Deforestation Waste management

20. Effects of Global Warming : Climate change Harmful effects on plants and animals Strange diseases Effects on sea levels (Glaciers are melting, so the sea levels are increasing which result flood) Ozone become harmful Economic Consequences More lethal storms Effect on agriculture Effects on Biodiversity Increasing the average temperature of Earth

21. Protective Measures Reduce, Reuse, Recycle Use less heat and air conditioning Change a light bulb by CFL Drive Less and Drive Smart Buy Energy-Efficient Products Use less hot water Use the ‘’Off’’ Switch Plant a Tree Get a report card from your utility company Encourage others to conserve

22. 10. Ozone Layer Depletion : It is an invisible layer of protection around the earth. It protects us from the harmful rays of the sun. The depletion of Ozone layer is many poisonous gases like colro-floro corban (cfc) that are produces by human activities. After reaching the upper atmosphere, they cause a hole in ozone layer. This is one of the most serious and fatal environmental problem that requires ad-hoc legislation. Human beings are falling on their own swords by their own notorious activities. “The house has burnt by its own lamp”.

23. Protective Measures To enact legislation to restrict use of CFCs. In countries e.g. UK people are discouraged from using CFCs containing sprays. Avoid the consumption of gases dangerous to the ozone layer. Minimize the use of cars. Do not use cleaning products that are harmful to the environment and to us.   Maintain air conditioners.
