Environment plays a crucial part in our life. Therefore, we need to protect the environment as well as the ecosystem as much as possible. There are some main ways to do that. Firstly, a good strategy is to save energy and natural resources which are limited. We can use less energy by switching off all electronic devices when they are not in use, not wasting water, using a bike or a bus instead of driving a car. The government should also set a limit for the exploitation of resources. Secondly, we need to conserve the old forest, rainforest, build more safari and national parks, and plant more trees to make a place to live for wild animals. Prohibiting hunters who hunt animals out of the law allowance is also important. Last but not least, there is a must to raise people’s awareness. People should be encouraged strongly to do good things like: using less plastic things, not throwing trash everywhere,… I hope that in the future the earth will be cleaner.
