Thousands of wild amimals are in danger of being extinct in these days. This is a very serious problem because the existence of wild animals can keep natural balance. The circulation of world has lasted thousands of years. If one part of this circulation ---the wild animals became extinct, the result should be unimagineable.
The reasons why the number of wild animals sharply decreasing are not natural elimination but human being’s destruction such as invasion of habitats, environmental pollution as well as excessive hunting and killing, etc.
There are things we can do to help protecting wild animals. My few suggestions are:
Stop destruction of wildlife habitats,
Punish illegal hunting and killing
Recycle and reduce energy and goods consumption,
Minimize use of herbicides and pesticides.
