Why should we protect endangered animals? Part 02 Before-reading Part 03 While-reading 走进语篇 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。 ①The conservation of endangered species is not just a matter of ethical responsibility—it’s a fundamental necessity for the health of our planet. ②Many 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. ③Climate 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. ④Preserving 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. ⑤For 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. ⑥IFAW 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? 语篇类型 语篇内容 语篇结构模式 段落大意 Part 1: 1 Part 2: 2-5 Part 3: 6 说明文 Many human activities have been undeniably detrimental to many animal species, both directly and indirectly.

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! . 25 Thank you for your listening Lavf58.20.100 Packed by Bilibili XCoder v2.0.2 Lavf58.20.100 Packed by Bilibili XCoder v2.0.2 $$
