Welcome to Mr Aslanov’s cefr lessons

 
Q3. Global warming is called the greenhouse effect because the gases that are gathering above the earth 
make the planet comparable to a greenhouse. By trapping heat, the green-
house effect is warming the planet 
and threatening the environment. Current fears stem largely from the fact that global warming is occurring 
at such a rapid pace. Models are predicting that over the next century, the global temperature will rise by 
several degrees. 
Q4. Individuals often throw out goods without realizing that they could be dangerous for the environment. 
No matter where people put these materials, there is always a chance that they could find their way into the 
ground, and eventually into our bodies. Special research is necessary to provide data on the effects of every 
chemical as well as to learn how combinations of these chemicals affect human health. 
 
Q5. Only a few factors combine to create the problem of ozone layer depletion. The production and 
emission of CFCs, chlorofluorocarbons, is by far the leading cause. Many countries have called for the end 
of CFC production. However, those industries that do use CFCs do not want to discontinue usage of this 
highly valuable industrial chemical. So it’s important to make people realize the disaster CFCs cause in the 
stratosphere. 
Q6. Unlike some environmental issues, rainforest depletion has fortunately received significant public and 
media attention. According to some estimates, 50 million acres of rain forest are cut down every year. 
Every year, Brazil chops down an area of forest the size of the state of Nebraska. In Indonesia, Zaire, 
Papua New Guinea, Malaysia, Burma, the Philippines, Peru, Colombia, Bolivia, and Venezuela, rain 
forests that were once great have been lost. 
 
Q7. The world’s population has been booming for years. The population is now threatening to reach the 
stage where there are simply too many people for the planet to support. Greater populations pollute and 
consume more, ruining the environment and creating or intensifying a variety of problems. Also, with the 
food supply limited, the increase in population will make shortages in many parts of the world even worse.
