GREENHOUSE EFFECT The greenhouse effect is an increase in the amount of gases in the in the atmosphere. What are the causes of greenhouse effect? The greenhouse effect is due to the development of industry and the burning of fossil fuels like coal and oil, emission of methane from agriculture or waste and emission of freons from the industry, as well as deforestation, fires and motorization. What are the effects of greenhouse effect? The most dangerous is the global warming. Which results are melting of glaciers, difficulties in cultivation like lack of water and animal death . We can prevent the greenhouse effect reducing CO2(carbon dioxide) emission. GLOBAL WARMING The global warming is a gradual increase in world temperature. What are the reasons of global warming? It is caused by the introduction of gases into the atmosphere like coal or methane. Gases are collected in the atmosphere and can’t escape into space, so the temperature increases. Humans are the main cause of global warming, because they cut out forests, drives cars or burns wood. Research shows that the temperature has been rising for 50 years. The effects of global warming are rising water levels, weather disturbances and cataclysms. Drought leads to havoc. ACID RAIN Acid rain is a rain which contains large amounts of chemicals as a result of burning substances such as coal and oil. Acid rain can’t be easily distinguished from normal rainfall, but it’s impact on the environment is easy to see. Acid Rains are on areas where massive amounts of fossil fuels are burned. They have negative effects on nature. They cause tree extinction, a lot of diseases, corrosion of cars,monuments and pollute the waters. We can reduce the amount of acid rains by building installations, Building high chimneys so the gases rise higher, People can use sustainable energy sources like the sun, lime can be used to water to destroy acid.
