Protect the Natural World

Protect the Natural World
The natural world is our only home. It offers us clean air, fresh water and food to live, so protecting it is protecting ourselves.
Now nature is facing many problems: pollution is getting worse, lots of wild animals are losing their homes, and more and more forests are disappearing.
As students, we can do small things to help: we can save paper, take the bus more often, and never throw rubbish everywhere. Small actions can make a big difference, let's work together to protect our natural world.

这是一篇环保主题的英语短文写作题，写作思路如下：
1. 开篇点明保护自然世界的重要性：自然为人类提供生存必需的空气、水和食物，是人类赖以生存的基础，保护自然本质上就是保护人类自身。
2. 第二部分列举当前自然面临的典型问题：环境污染加剧、大量野生动物失去栖息地、森林被过度砍伐等。
3. 最后给出青少年力所能及的环保举措，比如节约资源、绿色出行、不乱扔垃圾，收尾呼吁大家共同行动。
全程使用八年级已学的基础词汇和句式，控制词数在80左右，不出现真实个人信息，保证逻辑通顺连贯。
