Many human activities have been undeniably detrimental to many animal species, both directly and indirectly. Currently, the extinction rate of species is up to 1,000 times higher than in pre-human times, and scientists suggest we are living through the planet’s sixth mass extinction. There has been a 73% decline in mammal, bird, reptile, amphibian, and fish species between 1970 and 2020. We’re losing biodiversity quicker than we ever have in the past. Climate change is in large part to blame—a study published in December 2024 showed that one-third of species on the planet will be at risk of extinction by the end of this century if greenhouse gas emissions continue increasing at current levels. Climate change is closely linked to biodiversity loss. So protecting—and restoring—biodiverse ecosystems is vital in the fight against climate change. Preserving endangered species safeguards the intricate balance of our planet’s life, ensuring a healthier and more secure future for ecosystems and people. Endangered species can also serve as indicators of environmental health. When populations decline, it can signify underlying issues such as habitat destruction, pollution, or climate change, which, if unaddressed, can threaten the stability of the entire ecosystem and many other species. For example, declining populations of bald eagles in North America allowed scientists to discover that the environment had been contaminated with DDT, a pesticide used to control mosquitoes and other insects. In this way, the bald eagle served as a warning sign for the environmental damage being done by DDT, allowing a ban on the chemical to be put in place and eagle populations to recover along with the environment. IFAW is a conservation and rescue organization with the mission to build a future where animals and people can thrive together. With this goal in mind, it’s essential to examine why we must protect endangered species—why are they so important? And what would our world look like without them? -https://www.ifaw.org/international/journal/why-should-we-protect-endangered-animals 牛刀小试 ( ) 1.

Below are some of the primary human activities leading to the endangerment of species: Habitat Destruction Habitat destruction is one of the leading causes of species endangerment. The destruction of natural habitats can occur due to various human activities, such as deforestation, urbanization, and land conversion for agricultural purposes. This reduces the available resources and shelter for species, resulting in a decline in their populations and an increased risk of extinction. Habitat destruction can also cause habitat fragmentation, leading to isolated populations of species that are more vulnerable to genetic and environmental factors. Loss of habitat can also affect species’ migration patterns, causing further population decline. Over-Exploitation Over-exploitation refers to the excessive harvesting or exploitation of species for commercial or personal use. This leads to a decline in species’ populations and can result in their extinction. This can occur through overfishing, hunting, and the illegal trade of wildlife products. In some cases, over-exploitation can also lead to the rapid decline of populations, making it difficult for species to recover. In addition, over-exploitation can also cause a decline in the genetic diversity of populations, making them more vulnerable to environmental factors and diseases. Pollution Pollution is another human activity that has a significant impact on endangered species. Releasing toxic substances into the environment can affect the health and survival of species. For example, releasing toxic chemicals into waterways can harm fish and other aquatic species, leading to a decline in their populations. Pollution can also affect the food chain, leading to a decline in the populations of species that rely on contaminated food sources. In addition, pollution can also cause a decrease in the genetic diversity of populations, making them more vulnerable to environmental factors and diseases. -https://sciencerecent.com/environment/species/ 参考译文 人类活动对濒危物种的影响 众所周知，人类活动对环境及其居民产生了重大影响。以下是一些导致物种濒危的主要人类活动： 栖息地的破坏 栖息地的破坏是物种濒危的主要原因之一。自然栖息地的破坏可能是由于各种人类活动，如森林砍伐、城市化和土地转为农业用途。这减少了物种的可用资源和庇护所，导致其种群数量下降，灭绝的风险增加。 栖息地的破坏也会导致栖息地破碎化，导致物种的孤立种群更容易受到遗传和环境因素的影响。栖息地的丧失也会影响物种的迁徙模式，导致种群数量进一步下降。 过度开发 过度开发是指为了商业或个人用途而过度采伐或开发物种。这会导致物种数量的减少，并可能导致它们的灭绝。这可能通过过度捕捞、狩猎和野生动物产品的非法贸易发生。 在某些情况下，过度开发还可能导致种群数量迅速下降，使物种难以恢复。此外，过度开发还可能导致种群遗传多样性下降，使它们更容易受到环境因素和疾病的影响。 污染 污染是另一种对濒危物种有重大影响的人类活动。向环境中释放有毒物质会影响物种的健康和生存。例如，向水道中释放有毒化学物质会伤害鱼类和其他水生物种，导致其数量下降。 污染还会影响食物链，导致依赖受污染食物来源的物种数量减少。此外，污染还可能导致种群遗传多样性的减少，使它们更容易受到环境因素和疾病的影响。 答案与解析 牛刀小试 1.

Today, many species are facing extinction due to habitat loss, pollution, and illegal hunting. For example, tigers and pandas have seen their populations drop sharply, threatening biodiversity. To protect endangered animals, we must take action. Governments should establish more nature reserves and enforce strict anti-poaching laws. Individuals can contribute by reducing plastic use and supporting wildlife conservation organizations. Education also plays a key role—raising awareness helps people understand the urgency of the issue. In my opinion, everyone has a responsibility to protect endangered species. Small daily efforts, combined with global cooperation, can make a big difference. Let’s act now before it’s too late! 参考译文 为什么应该保护濒危动物？ 保护濒危物种不仅仅是一个道德责任问题，也是我们地球健康的基本需要。 不可否认，许多人类活动对许多动物物种都有直接或间接的危害。目前，物种灭绝的速度是人类出现之前的1000倍，科学家们认为我们正在经历地球上的第六次大灭绝。从1970年到2020年，哺乳动物、鸟类、爬行动物、两栖动物和鱼类的数量减少了73%。我们正在以前所未有的速度失去生物多样性。 气候变化在很大程度上是罪魁祸首——2024年12月发表的一项研究表明，如果温室气体排放继续以目前的水平增长，到本世纪末，地球上三分之一的物种将面临灭绝的危险。气候变化与生物多样性丧失密切相关。因此，保护和恢复生物多样性生态系统对应对气候变化至关重要。 保护濒危物种可以维护地球生命的复杂平衡，确保生态系统和人类拥有一个更健康、更安全的未来。濒危物种也可作为环境健康的指标。当种群数量下降时，可能意味着潜在的问题，如栖息地破坏、污染或气候变化，如果不加以解决，可能会威胁到整个生态系统和许多其他物种的稳定。 例如，北美秃鹰数量的减少让科学家们发现环境被DDT污染了，DDT是一种用来控制蚊子和其他昆虫的杀虫剂。通过这种方式，秃鹰成为滴滴涕对环境造成破坏的警告信号，允许禁止使用这种化学品，鹰的数量也随着环境的恢复而恢复。 IFAW是一个保护和救援组织，其使命是建立一个动物和人类共同繁荣的未来。有了这个目标，我们就有必要研究一下为什么我们必须保护濒危物种——为什么它们如此重要？如果没有它们，我们的世界会变成什么样子？ 1 / 1 学科网（北京）股份有限公司 $$
