大自然是伟大的`，生态是复杂的，生命是奥妙的，而我们了解得太少了，尚不及“寄蜉蝣于天地，渺沧海之一粟。”地球是丰富多彩，物象万千的。一根草，一棵树，一个动物，一个群体，一个人，一个家庭，一个民族，一个社会。都是自然不断进步的结果。天生的动物，天生的植物，天生所有的植物，天生所有的生命都是有用的。它们的存在就说明有用。一看到森林，就向想到母木材；一看到河流就想到发电；一看到草原，就向想到牛羊肉和羊绒衫；一看到动物，就向想到能不能吃，能不能用，能不能入药。
珍惜动物是社会的财富，我们必须保护。一些虽很常见，但对人类有益的动物，我们同样应该爱护。植物也是人类的朋友。植物能够帮助人们净化空气，减少噪音，保持水土，防风固沙，调节气候。真是为人类做了不少贡献。
为了保护生态平衡，我国还建立了不少自然保护区或国家公园，就地保护野生濒危动物。
大自然是我们可靠的朋友，它们无时无刻陪伴着我们。人类和大自然互相依存，共同构成和谐的自然界。我相信信息+创造=21世纪。
