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.

The Earth is our home, but it seems that we do not do enough necessary things to protect it. People cut down the trees, kill thousands animals, and dig up the ground every day. All of our actions create only negative influences to the Earth, and I think we should do something to save it before it is too late. It is not hard for us to cut off products from animals. We do not need to use accessories which are made from animals’ skin and fur, and we should not use things that are made from toxic materials. The oceans now have more trash than living animals, and it is a terrible thing to imagine. We should reduce the amount of trash, especially plastic and toxic waste. Instead, we can use recycled things such as cloths, metal, or wood in our daily life. Everyone can join by doing such small things, and I think it is not very difficult. Environment is everything around us and what we need to maintain our life, so our priority should be keeping it clean and healthy.

Trái đất là ngôi nhà của chúng ta, nhưng dường như chúng ta không làm đủ những điều cần thiết để bảo vệ nó. Người ta chặt cây, giết hàng ngàn động vật và xới tung mặt đất mỗi ngày. Tất cả các hành động của chúng ta chỉ tạo ra những ảnh hưởng tiêu cực đến Trái đất, và tôi nghĩ chúng ta nên làm gì đó để cứu nó trước khi quá muộn. Không khó để chúng ta cắt giảm những sản phẩm từ động vật. Chúng ta không cần sử dụng các loại phụ kiện được làm từ da và lông thú, và chúng ta không nên sử dụng những thứ được làm từ vật liệu độc hại. Các đại dương bây giờ có nhiều rác hơn động vật sống, và đó là một điều khủng khiếp để tưởng tượng. Chúng ta nên giảm lượng rác, đặc biệt là rác thải nhựa và độc hại. Thay vào đó, chúng ta có thể sử dụng những thứ có thể tái chế như vải, kim loại hoặc gỗ trong cuộc sống hàng ngày. Mọi người đều có thể tham gia bằng cách làm những việc nhỏ như vậy và tôi nghĩ nó không quá khó. Môi trường là tất cả mọi thứ xung quanh chúng ta và những gì chúng ta cần để duy trì cuộc sống, vì vậy ưu tiên của chúng ta là giữ cho nó sạch sẽ và lành mạnh.
