Save Earth, Reduce Pollution Submitted by: Aman Bhatia Bushra Imran Pooja Upadhyay Samson Thomas Suvodip Mukherjee
Some Facts…. More than 1 billion people worldwide don’t have access to safe drinking water. People who live in high-density air pollution area, have 20% higher risk of dying from lung cancer, than people living in less polluted areas. 5000 people die every day as a result of drinking unclean water. Pollution kills more than 1 million seabirds and 100 million mammals every year. Almost 80% of urban waste in India is dumped in the river Ganges. There are more than 500 million cars in the world and by 2030 the number will rise to 1 billion. This means pollution level will be more than double.
Climate change and Deforestation Heat waves, droughts, flooding, storms, decrease in crop yields, and rising sea levels are just some of the effects we’re seeing from climate change . Deforestation is one cause of climate change. But beyond that, it’s also responsible for the depletion of oxygen in the atmosphere and the displacement of wildlife.
Pollution According to the World Health Organization, “air pollution is now the world’s largest single environmental health risk.” That’s because it’s responsible for approximately 3.7 million deaths a year (according to a 2012 study ). “cities currently generate approximately 1.3 billion tonnes of solid waste per year….and with the current trends in urbanization, this number will likely grow to 2.2 billion tonnes per year by 2025 - an increase of 70 percent.”
Loss of biodiversity and Oceanic dead zones As a result of overfishing, deforestation, habitat destruction, pollution, and other factors, more plants and animals are nearing extinction Dead zones occur in the ocean when oxygen levels in the water fall until marine life cannot survive.
Simple Solutions…. Plant more trees Don’t waste water Use cloth bag and don’t burn plastic Stop smoking or at least follow the “No Smoking” sign Use unleaded gasoline in your cars Stop smoking or at least follow the “No Smoking” sign Use unleaded gasoline in your cars
Solutions for Industrial Pollution There are two approaches through which pollution can be reduced: Reducing consumption or usage of a polluting product Treatment of wastes, discharges and disposals of a pollutant Industries should use fuel with lower sulphur content. Industries should monitor their air emissions regularly and take measures to ensure compliance with the prescribed emission standards. Industries should strictly follow applicable government regulations on pollution control. Organic waste should be dumped in places far from residential areas.
Solution to Air pollution Governments throughout the world have already taken action against air pollution by introducing green energy. Some governments are investing in wind energy and solar energy, as well as other renewable energy, to minimize burning of fossil fuels, which cause heavy air pollution . Car manufacturing companies are also building more energy efficient cars, which pollute less than before . Encourage your family to use the bus, train or bike when commuting. If we all do this, there will be less cars on road and less fumes . Use energy (light, water, boiler, kettle and fire woods) wisely . Recycle and re-use things. This will minimize the dependence of producing new things.
EVEN or ODD ??? The Delhi government's new proposed rule to run vehicles with odd and even numbers on alternate days This system was implemented in Beijing in 2008 just before the summer Olympics. While the rule was initially said to be temporary, it turned out to be so effective the government made it permanent Air-pollution levels in Delhi decreased 15 percent during the 15-day period
Steps taken by Government C ompulsory PUC (Pollution Under Control) certification of petrol driven vehicles which tests for carbon monoxide and hydrocarbons . U se of non-polluting Compressed Natural Gas (CNG) only as fuel by all buses and trucks . Clean India Mission (Swatch Bharat Abhiyan) has been launched. Standards for sewage treatment plants have been notified for comments of stakeholders . Out of 2800 major industries, 920 industries have installed on-line continuous (24X7) monitoring devices to control pollution. National Air Quality index was launched by the Prime Minister in April, 2015 starting with 10 cities.
Steps taken by Industries Emission standards have been notified under the Environment (Protection) Act, 1986 to check pollution . As many as 24 critically polluted areas have been identified . Minimal National Standards (MINAS) have been presented for highly polluting industries Industrial wastes like slags, red mud etc. are generated from iron and steel and during extraction of non-ferrous metals such as aluminium and copper. The slags are dumped in the vicinity of plant while red mud is disposed as slurry .
Some Ray of Hopes…… Emissions of man-made greenhouse gases appear to have declined slightly in 2015 , dip of 0.6 percent over 2014 levels. The single biggest factor appears to be a marked reduction in China’s use of coal to make electricity . In September , 2016 the UN have agreed on a new global development to-do list (the Sustainable Development Goals, or "SDGs") that will pick up where the last to-do list from 2000 left off (known as the Millennium Development Goals or "MDGs"). Then, in December, the UN Climate Change Conference in Paris have set new climate action targets, which are vital in combating climate change.
Some words…. “Earth provides enough to satisfy every man’s needs, but not every man’s greed.” - Mahatma Gandhi “One person alone cannot save the planet’s biodiversity, but each individual’s effort to encourage nature’s wealth must not be underestimated.” - United Nations Environment Programme (UNEP)
