    Why should we protect the environment？Firstly，our environment is facing a great challenge now.Many human activities have made much pressure on the environment.For example，with the increasing number of the cars，the carbon（碳） in the air also increases greatly.The chemicals that go into making plastics or other goods is highly toxic （有毒的）.The toxins can make the soil difficult to grow plants.And people cut down many trees，which makes many animals lose their homes ...Secondly，the environment supports the life of each and every living thing on the earth.Only when the environment is protected can we have a better life.
    But how to protect the environment？To reduce air pollution，people can choose to use public transport，families can share cars rather than each member of the family has a car，or use bicycles when possible.Also，they can plant more trees，which can take in the carbon.To reduce soil and water pollution，the government should encourage factories to find more green ways to develop new products and reduce less amount of the chemicals.And factories shouldn't be allowed to pour waste into the water.To protect the biodiversity（生物多樣性），people should stop cutting down trees and leave the animals their living homes.More importantly，people should have the awareness （意識(shí)） of the importance of environmental protection.The little things people do will do a long way in environmental protection.
