The Clean Air Act is making many companies change their products to decrease these problems. . Part of the law says that you may not put a certain amount of pollutants in the air. . The Clean Air Act has also made car companies change some of the things inside of the cars. . Cars pollute a lot. . While cars make more than half of the worlds smog. Br cars, buses, and trucks which are also responsible for over 50 of dangerous chemicals let into the air.

Another thing that makes global warming worse is when people cut down trees. . Trees and other plants collect carbon dioxide (CO2 which is a greenhouse gas.(deforestration) br / Global warming it is also destroying many huge forests, many more fires that wipe out whole forests. . This happens because global warming can make the earth very hot. Carbon dioxide is the air that our body lets out when we br / breathe. With fewer trees, it is harder for people to br / breathe because there is more co2 in the air. . Plants br / collect the co2 that we breathe out, and they give back br / oxygen that we breathe. . With less trees and other br / plants, such as algae, there is less air for us, and more br / greenhouse gases are sent into the air.

Br / makes the sea rise : the water covers many low land islands, the plants and causes some of them to die so, the animals lose a source of food, along with their habitat, but people lose two sources of food, plant food and. Global warming, is harming and killing algae in the ocean. fewer algae is a problem because there is less food for us and many animals in the sea. . One thing that causes global warming is electrical pollution, fossil fuels are burned to create electricity. . Fossil fuels are made of dead plants and animals.

The heat and light can get through the mini atmosphere, but it cant get out. . As a result, the temperature rises. Sometimes the temperature can change in a way that helps. . greenhouse effect makes the earth appropriate for people to liveon. .

On the other hand it would be burning hot. during the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter it, so people, plants, and animals would be exposed to all the light and heat. What is global warming doing to the environment?
Global warming has become perhaps the most complicated issue facing world nowadays. What is global warming? . br / The Planet Is heating Up—and Fast br /. The earth heats up (the temperature rises) It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earths atmosphere, which increases the temperature. . This hurts many people, animals, and plants. What is the greenhouse effect? Br / ul li The greenhouse effect is when the temperature rises because the suns heat and light is trapped in the earths atmosphere.

Conclusion global warming is due to the increased carbon dioxide and greenhouse gases in air due to pollution caused by human and it is predicted that it will cause variety of negative effects. Thus to reduce the global warming we should develop some steps for the prevention, we must avoid unnecessary use of automobiles, plant plenty of trees recycle the objects and make absolute use of nonconventional energy sources. Apart from that we should organize self-awareness programmes, plan exhibitions in different parts of countries to create awareness on global warming. Also to slow down global warming, adaptation schemes must be forwarded. Constructing flood defences, banning buildings close to sea areas are some of the measures we can adapt.

The planet cuts and burns nearly 34 million acres of trees each year, including millions of acres of rainforest. Trees and plants take up the carbon dioxide and provide us pure, clean, breathable oxygen as a free by product of the plant life cycle. Effects of global warming. There are numerous Effects of Global Warming, some of the effects of global warming observed across the world are rise in sea levels due to rise in temperature, the Glaciers present in polar regions are melting rapidly, as a result there is sufficient rise. Droughts and Floods Higher temperature leads to faster evaporation of water and leads to drought in one part, and heavy rainfall causes flooding in other part of the world. Experts have estimated that, drought conditions might be increasing by at least 66 percent in upcoming years.
Effects on biodiversity wildlife researchers have noticed some of the strong species migrating to the poles, far north and far south to maintain their needed habitat, for example the red fox normally an inhabitant of North America is now seen living in the Arctic. Also it has been noticed that loss of species and endangerment is rising along with the global temperatures. Prevention of Global Warming we can prevent Global Warming by reducing the demand of fossil fuels and by using the energy more wisely. Some of the simple actions which can help us to reduce the effects the global warming are reuse, reduce and recycle we can reduce the emission of carbon dioxide by choosing reusable products instead of disposables. Using Compact Fluorescent Light (cfl we can save energy by replacing regular light bulbs with compact fluorescent light (CFL) bulbs, because cfls uses 75 less energy than 60-watt incandescent light bulb. Also cfls last 10 times longer than incandescent bulbs and give off 70 percent less heat. by planting Trees we should plant more and more trees as they absorb carbon dioxide and give off oxygen. They are an integral part of the natural atmospheric exchange cycle here on Earth. turning of Electrical Appliances we can save electricity and reduce global warming by turning off lights, television, video player, stereo and computer and many other electrical appliances, when not in use.

Some of the main causes of Global Warming are. Greenhouse Effects, greenhouse effect is the phenomenon in which the heat and guaranteed light of sun enters to the earth's atmosphere but cannot go out as they are trapped by the greenhouse gases, as a result temperature rises. Greenhouse gases, greenhouse gases mainly comprises of carbon dioxide, methane, and nitrous oxide. These gases are lighter than air, so they rise up to the outer limits of the earths atmosphere and settle up there, making an impenetrable barrier that traps heat from escaping out into the space, and keeping it within our environment, and increases the temperature. Agriculture, agriculture produces large amount of methane and nitrous oxide worldwide, as accounted by ipcc. There are numerous agricultural sources of greenhouse gases. Livestock grazing, waste management and digestive gases contribute half of the emissions produced by agriculture. Nitrogen fertilizers (used for increasing production) release nitrous oxide and comprise 35 per cent of agricultural emissions. deforestation According to nasa (National Aeronautics and Space Administration deforestation is responsible for nearly one-fourth of the amount of carbon emitted to the atmosphere.
'Global warming' is an expression which refers to the effect of essay human activities that produces the unnatural change on the climate. It is an increase in earths temperature due to burning of fossil fuels (coal, oil and gas) and large-scale deforestation, which results in emission of large amounts of 'greenhouse gases' to the atmosphere. Now the question arises that, what causes Global Warming? Causes of global warming, according to Scientists and government organisations, concentration. Greenhouse gases in the atmosphere due to greenhouse effect is the major causes of Global Warming. These gases especially co2 have heat trapping capability. So they trap heat and cause the greenhouse effect, rising global temperatures.
