环境污染（environment pollution）是指人类直接或间接地向环境排放超过其自净能力的物质或能量，从而使环境的质量降低，对人类的生存与发展、生态系统和财产造成不利影响的现象。具体包括：水污染、大气污染、噪声污染、放射性污染等。
人类生产活动对自然环境的污染主要包括两个方面：一是工业生产过程中产生的废水废气废渣和农业上使用的农药、化肥等对水、大气、土壤、食品的污染；二是在自然资源开发和利用中，产生的对环境的污染。
相信大家对于环保都有一定的认识，也曾读过关于限塑令，节约用水保护环境等为主题的作文。我们来看一下这篇范文，试着找出其中的优点与不足。

对于这类话题，我们可以从以下几方面入手：
1. 什么是低碳生活？即回答what is Low-carbon life?
2. 怎样身体力行来做到低碳生活？How should we do to practice the low carbon life?
3. 倡导大家身体力行，共同保护我们赖以生存的大自然。Let every one join in the low carbon life.
看了以上的论述，现在我们就以下面的主题来练练手吧。
