生物多样性作文？本作文是关于小学六年级550字的作文，题目为：《生物的多样性》，欢迎大家踊跃投稿。 生物的多样性这个词对于我来说是一个生词。刚看到这个词时，我觉得生物的多样性离我们很远，但实际上生物的多样性在我们的生活中无处不在，大熊猫、珙桐、扬子腭都是我国特有的动植物。中国还是地球上生物多样性最丰富的12个国家之一呢。那么，生物多样性作文？一起来了解一下吧。
生物多样性使这个星球上的生命得以持续。通过森林吸收二氧化碳这种温室气体，我们才得以呼吸空气。通过土壤、微生物和气象变化移除了水中的污物我们才得以喝到水。全部的物种--植物、动物、微生物，组成了生命。然而，我们却威胁到了许多物种，而正是它们构成地球这个宏伟的不能代替的支持生命的系统。但是，为什么？我们对此怀着深深的疑问。一些无名的物种真的有这么重要？假如这个世界上的物种减少到牛、羊、鸡、猪和足够的放在动物园的动物，难道我们就不能舒服的过日子了吗？为什么我们必须关注一些特种的鸽子或者是一种火蜥蜴或者是一种生活在遥远沼泽里的小小植物？它们灭绝了关我们什么事？毕竟，我们还有许多种别的鸽子和许多种别的蜥蜴，还有许多种植物留下来。
实际上，即使是一些物种灭绝了，还是有不少物种存留下来的。迄今为止，我们已经识别了175万个物种，但是科学家们认为，实际上地球上存在有1300万或1亿种物种。
重要的事情是所有的这些物种是与其它物种相互联系的，正如同我们依赖植物和动物为食一样。顺着食物链，我们也同样依赖我们吃的动物、植物的食物--又一群植物、动物。如果其中一个特定的物种失去了它的栖息地或者不再找得到它常吃的食物，就会灭绝掉。
保护生物多样性英语作文如下：
Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals, and because once they are gone, there will never be any more. Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers' stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.

动物是自然资源，在整个历史过程中，人类一直在糟蹋着这种资源。
生物多样性是生物及其与环境形成的生态复合体以及与此相关的各种生态过程的总和，包括数以百万计的动物、植物、微生物和它们所拥有的基因以及它们与其生存环境形成的复杂的生态系统，是生命系统的基本特征。生命系统是一个等级系统，包括多个层次或水平：基因、细胞、组织、器官、种群、物种、群落、生态系统、景观。每一个层次都具有丰富的变化，即都存在着多样性。但在理论与实践上重要且研究较多的主要有基因多样性（或遗传多样性）、物种多样性、生态系统多样性和景观多样性。现在，人们往往把生物多样性视为生命实体本身，而不仅仅看作生命系统的重要特征之一。人类文化的多样性也可被认为是生物多样性的一部分。正如遗传多样性和物种多样性一样，人类文化（如游牧生活和移动耕作）的一些特征表现出人们在特殊环境下生存的策略。同时，与生物多样性的其它方面一样，文化多样性有助于人们适应不断变化的外界条件。文化多样性表现在语言、宗教信仰、土地管理实践、艺术、音乐、社会结构、作物选择、膳食以及无数其它的人类社会特征的多样性上。
生物多样性是人类赖以生存的物质基础，其价值可以从下列两个方面得以了解。第一，直接价值。从生物多样性的野生和驯化的组分中，人类得到了所需的全部食品、许多药物和工业原料，同时，它在娱乐和旅游中也起着重要的作用；第二，间接价值。
生物的多样性
地球上除了人类之外，还有各种各样的生物，小到肉眼看不到的细菌，大到身长数十米的鲸。即使人类的科学发明与创作，也无法与大自然多种多样的生物相比。
生物的多样性包括动物、植物、微生物等物种的多样性，它们与人类生活密不可分。直接价值就是生物为人类提供了食物、纤维、建筑和家具材料、药物及其他工业原料。
当我们生病的时候，我们从自然界中寻找治疗方法。同时很多植物和动物还可以入药，为医药提供了多种有效的成分。生物的多样性关系到了人类的健康。
汽车尾气污染、工厂废气污染、发电厂的空气污染，垃圾处理等等，都会导致空气的严重污染。树和其他绿色植物会吸入二氧化碳，然后释放出氧气，生物的多样性净化了空气。
人类模仿动物发明了很多，通过大乌龟背小乌龟，发明了转动的坦克;通过鸟在空中飞行，发明了飞行器;通过鱼儿游泳，发明了潜水艇。

The Importance of Biodiversity
Biodiversity, the variety of life on Earth encompassing different species, ecosystems, and genetic variation within species, is a cornerstone of our planet’s life support system. This immense diversity is crucial for human wellbeing and survival.
Firstly, biodiversity plays a vital role in providing essential ecosystem services. These include clean air and water, pollination, nutrient cycling, soil fertility, natural disaster reduction, disease control, and climate regulation. These services are indispensable for maintaining the health and stability of our environment.
Secondly, biodiversity offers us a wide range of resources. From food, fuel, fibres, to medicines, biodiversity is the source of many of the goods and services we rely on daily. These resources are not only essential for our livelihoods but also for our health and wellbeing.
Furthermore, biodiversity is important for maintaining the balance of ecosystems. This balance ensures the longterm sustainability of life on Earth. Ecosystems with high biodiversity are more resilient to disturbances and can recover more quickly from disruptions.
However, human activities such as deforestation, pollution, climate change, and overexploitation of natural resources are causing a biodiversity crisis. The loss of biodiversity can lead to the collapse of critical ecosystem services, making it more difficult to provide basic needs for the world’s growing population. This, in turn, can have catastrophic consequences for both the environment and human society.
Therefore, it is crucial to protect and conserve biodiversity. This requires a combination of government policies, education and awarenessraising, scientific research, and community engagement. Additionally, we must reduce our impact on the environment by adopting sustainable practices in agriculture, forestry, fisheries, and industry.
In conclusion, biodiversity is essential for our planet’s life support system and human wellbeing. It is more important than ever that we take action to protect and conserve biodiversity before it is too late. By working together, we can ensure a future where biodiversity thrives and continues to provide the benefits we all depend on.
以上就是生物多样性作文的全部内容，生物多样性的珍贵与我们日常生活的疏离，使得我们更倾向于将那些展示生物多样性的艺术品视为珍宝。一幅描绘热带生物多样性的印象派画作，在拍卖会上能够卖出高达四千万的价格。然而，当涉及到实际存在的物种时，我们是否愿意投入同样的热情与资源去保护它们呢？随着越来越多的人选择城市生活，内容来源于互联网，信息真伪需自行辨别。如有侵权请联系删除。
