3.Researchers and many scientists are concerned that the earth's climate and atmosphere are becoming warmer.What scientists do agree on is that the temperature will continue to increase if measures are not taken to reduce pollution and emissions(排放物) from cars and factories.It is widely agreed that oil and coal create greenhouse gases.These emissions include carbon dioxide,which is the cause of most of the global warming problems.The loss of trees in many areas is making the problem worse,because trees and plants absorb carbon dioxide and release oxygen.The fewer trees that are left standing,the less carbon dioxide can be absorbed.
Scientists predict that the sea level will rise,ice caps will melt,and some animals and plants will fail to survive because their homes will disappear.There may be more deserts and less available farmland because of the dry ground,and there may be more storms and floods.
Some countries,including the UK and the US,are taking steps to prevent the situation from becoming worse.There are programmes to educate citizens and students about the situation and recycling waste is becoming more common.Using more alternative(替代的) energy sources is also a good way to prevent global warming.
One thing that everyone can do is limit their use of energy every day,and you can do this no matter how old,or young,you are.Try to limit the unnecessary use of electricity and work to save energy every day.
