often and has an impact on the environment, both positive and negative.

　　Wildlife is a very general term for life in ecosystems. Deserts, rainforests, plains, and other areas-including the most built-up urban sites-all have distinct forms of wildlife.

　　Humans have historically tended to separate civilization from wildlife in a number of ways; besides the obvious difference in vocabulary, there are differing expectations in the legal, social, and moral sense. This has been a reason for debate throughout recorded history. Religions have often declared certain animals to be sacred, and in modern times concern for the environment has provoked activists to protest the exploitation of wildlife for human benefit or entertainment. Literature has also made use of the traditional human separation from wildlife.

⑵ Warming up by talking about key threats to wildlife

Many animals are threatened by human actions. But what are the key threats to them?

Key Threats to Wildlife 1. Habitat Loss - Because our population is growing and our cities are sprawling into the countryside, fewer natural wildlife habitat areas are left each year.

2. Climate Change - Because many types of plants and animals have specific habitat requirements, climate change could cause disastrous losses of wildlife species in China.

3. Pesticides and Toxic Chemicals - Pesticides are deliberately spread to make the environment toxic to certain plants, insects or rodents, so it shouldn't be surprising that other plants and wildlife are often harmed at the same time.

4. Non-native Species - Over the past 150 years, many non-native plants, molluscs, insects, fish, birds, mammals, and diseases have found their way to China.

5. Mismanagement - Some native wildlife can become a problem when released from their natural population controls.
