1.

Read the following text and interpret it. " More recently, scientists are discovering large volumes of methane under the frozen tundras of the far northern latitudes (mainly in the vast expanses of northern Russia). As global temperature increases, the ice in the tundra melts more. The methane that is trapped under the ice escapes into the atmosphere, increasing the global temperatures. In turn, this causes even more ice to melt, releasing even more methane, and so on. Methane is said to be even more powerful than carbon dioxide as a greenhouse gas. "

Answer»

1. Global warming has been increasing. 

2. As global temperature increases, the ice in the tundra melts more. 

3. The methane that is trapped under the ice escapes into the atmosphere, increasing the global temperature. 

4. Methane is even more powerful than carbon dioxide as a green house gas. 

5. Then it is our responsibility to reduce global warming. 

6. This global warming leads to climatic changes. 

7. Hence human activities that lead to global warming are to be reduced.

  • Practices like hunting and poaching needs to be banned and strict regulations need to be implement in order to save the lives of animals.
  • Various projects for different animals which aim for saving and maintain the population of endangered species needs to be implement.
  • Number of wildlife sanctuaries, biosphere reserves, and national parks needs to be increased so that we can protect them by providing them their natural habitat.
  • Human intervention in their habitats needs to be in balance form which do not cause any harm to them.
  • Government needs to implement strict laws against crimes related to wildlife and needs to make people aware about the importance of wildlife and how they can contribute in their conservation.
