I live in a big city where all people face up to a number of environmental challenges, especially pollution. And when I learn about the effects of pollution on human health as well as human impacts on the environment, I want to know more and more.You know, nowadays we're facing a lot of environmental issues, but the one that concerns me most is pollution. I see people around me live in places with high level of air pollution and some of them end their lives in hospital with lung cancer. Water pollution also makes my family and my neighbours worried because we live near To Lich River. We're not sure when it rains, toxic chemicals from river might pollute our fresh drinking water.I think we can contribute to conserve our planet by switching off unnecessary lights, riding a bicycle, using public transport, using less petrol and electricity, or saving on water, recycling our rubbish … In this way, we all can help to protect our environment. Thanks for listening.

Nowadays, the development of human world causes causes many bad effects to the environment. We throw garbage everywhere, exploit too much natural resources or contaminate the air. Therefore, our environment is being seriously polluted and we need to protect it from now. First of all, we should reduce, reuse and recycle. Instead of using plastic bags, we can use leaves to wrap food. We can recycle plastic bottles, cans, paper to reduce garbage. Using public transports and decreasing the number of motorbikes and cars are also good ways to reduce carbonic in the air. Besides, we should purify contaminated lakes or rivers in order to lessen the pollution in the water.Last but not least, the gorvernment should propagandize about protecting the environment to everybody so that they can aware of it. Especially, we need to punish people who contaminate the environment with great severity. In conclusion, the Earth is our home so protecting it is everyone's responsibility.
