观察环境变化,生物多样性的作文

英文回答：

Observing changes in the environment and biodiversity

is an important task that helps us understand the impact of

human activities on the natural world. As a nature

enthusiast, I have always been fascinated by the incredible

diversity of life forms and how they adapt to their

surroundings.

One significant change that I have noticed in the

environment is the decline in the population of certain

species. For example, in my local area, the number of

butterflies has significantly decreased over the past few

years. This decline can be attributed to various factors

such as habitat loss, climate change, and the use of

pesticides. It is disheartening to witness such a decline

in biodiversity, as butterflies not only add beauty to our

surroundings but also play a crucial role in pollination.

Another change that I have observed is the invasion of

non-native species. Invasive species, such as the Asian

longhorned beetle, have been introduced to new habitats and

pose a threat to native species. These invasive species can

outcompete native species for resources and disrupt the

delicate balance of ecosystems. This situation reminds me

of the idiom "a fish out of water," which refers to someone

who is in an unfamiliar or uncomfortable situation. Just

like the fish, these invasive species are not adapted to

the new environment and can cause harm.

Furthermore, climate change has also had a significant

impact on biodiversity. Rising temperatures and changing

weather patterns have disrupted the natural cycles of many

species. For instance, migratory birds that rely on

specific weather conditions for their annual journeys may

struggle to find suitable habitats along their routes. This

situation can be described using the phrase "the early bird

catches the worm," meaning that those who are prepared and

act quickly will benefit. In this case, however, the early

arrival of migratory birds may not coincide with the

availability of food sources, leading to negative

consequences for their survival.

观察环境变化和生物多样性的变化是一项重要任务，它帮助我

们了解人类活动对自然界的影响。作为一个热爱大自然的人，我一

直对生命的多样性以及它们如何适应环境感到着迷。

我观察到的一个重要变化是某些物种数量的下降。例如，在我

所在的地区，蝴蝶的数量在过去几年中显著减少。这种下降可以归

因于栖息地的丧失、气候变化和农药的使用等各种因素。看到生物

多样性如此下降令人沮丧，因为蝴蝶不仅为我们的环境增添了美丽，

还在传粉过程中起着至关重要的作用。

我观察到的另一个变化是外来物种的入侵。亚洲天牛等外来物

种被引入到新的栖息地，对本土物种构成威胁。这些外来物种可以

与本土物种竞争资源，并破坏生态系统的微妙平衡。这种情况让我

想起了习语“鱼离开水”，意思是处于陌生或不舒适的环境中。就

像鱼一样，这些外来物种没有适应新环境，并可能造成伤害。

此外，气候变化也对生物多样性产生了重大影响。不断上升的

温度和变化的天气模式扰乱了许多物种的自然周期。例如，依赖特

定天气条件进行年度迁徙的候鸟可能难以在迁徙路线上找到合适的

栖息地。这种情况可以用习语“早起的鸟儿有虫吃”来形容，意思

是那些准备好并迅速行动的人将受益。然而，在这种情况下，候鸟

的早期到达可能与食物来源的可用性不一致，对它们的生存产生负

面影响。
