WATER POLLUTION
Yangzhou, China Miles
The four basic natural resources are water, air, land and energy. We need water for multiple uses and a certain quality is required. Its use leads to the generation of wastewater that can cause an impact on the environment.
As far as future prospect is concerned, I am sure that good results will be achieved in this respect. Rivers which used to be contaminated by industrial wastes will be cleaned and fish which could not live there a few years ago will be again. To conclude, it seems obvious that tomorrow will be better and brighter only if everyone does his part and tries hard to seek solutions for its control.
In addition, factories in towns and cities must be prohibited from draining waste liquids into rivers before they are totally treated and purified. I feel if they violate relevant rules or laws, they should be fined heavily. Certainly, there are some other cures which are worth adopting.

保护海洋英语教学课件Lesson: Protecting the Ocean.Introduction:The ocean is a vast and interconnected body of water that covers over 70% of the Earth's surface. It is home to an incredible diversity of life, provides essential resources for人類, and plays a crucial role in regulating the Earth's climate. However, the ocean is facing numerous threats, including pollution, overfishing, climate change, and habitat loss.Threats to the Ocean:Pollution: The ocean is polluted by a variety of sources, including industrial waste, sewage, plastics, and oil spills. These pollutants can harm marine life, contaminate the food chain, and disrupt the balance of ecosystems.Overfishing: Overfishing occurs when fish areharvested at a rate faster than they can reproduce. Thiscan lead to population declines, ecosystem imbalances, and economic losses.Climate change: Climate change is causing the ocean to become warmer, more acidic, and less oxygenated. These changes can harm marine life, disrupt ecosystems, and threaten coastal communities.Habitat loss: Coastal development, dredging, and other activities can destroy or degrade marine habitats, such as coral reefs and seagrass beds. This can reduce biodiversity, disrupt food chains, and make marine life more vulnerableto other threats.Consequences of Ocean Degradation:The degradation of the ocean has far-reaching consequences for humans and the environment. It can:Reduce the availability of food, clean water, and other resources.Disrupt coastal economies and livelihoods.Exacerbate climate change.Endanger marine biodiversity.Threaten human health.Protecting the Ocean:Protecting the ocean is essential for the health of our planet and the well-being of future generations. There are a number of things that can be done to protect the ocean, including:Reducing pollution: Reducing the amount of pollution that enters the ocean from land-based sources is crucial. This can be achieved through measures such as wastewater treatment, litter cleanup, and recycling.Managing fisheries sustainably: Fisheries should be managed to ensure that fish stocks are harvested at sustainable levels. This involves regulating catch limits, using selective fishing gear, and establishing marine protected areas.Mitigating climate change: Taking action to mitigate climate change, such as reducing greenhouse gas emissions, will help to protect the ocean from the negative effects of warming, acidification, and deoxygenation.Protecting marine habitats: Marine habitats should be protected from destruction and degradation. This can be achieved through measures such as zoning, habitat restoration, and marine protected areas.Conclusion:The ocean is a precious and essential part of our planet. Protecting the ocean is crucial for the health of our planet and the well-being of future generations. Bytaking action to reduce pollution, manage fisheries sustainably, mitigate climate change, and protect marine habitats, we can help to ensure that the ocean remains healthy and productive for generations to come.。

初中英语写作：Save water PPT课件 图文
谢谢！ 学妹给我打电话，说她又换工作了，这次是销售。电话里，她絮絮叨叨说着一年多来工作上的不如意，她说工作一点都不开心，找不到半点成就感。 末了，她问我：学姐，为什么想 找一份 自己热 爱的工 作这么 难呢？ 我问她上一份工作干了多久，她 说不到 三个月 ，做的 还是行 政助理 的工作 ，工作 内容枯 燥乏味 不说， 还特别 容易得 罪人， 实在不 是自己 的理想 型。 我又问了她前几份工作辞职的原 因，结 果都是 大同小 异，不 是因为 工作乏 味，就 是同事 不好相 处，再 者就是 薪水太 低，发 展前景 堪忧。 粗略估计，这姑娘毕业不到一年 ，工作 却已经 换了四 五份， 还跨了 三个行 业。 但即使如此频繁的跳槽，她也仍 然没有 找不到 自己满 意的工 作。 2 我问她，心目中理想型的工作是 什么样 子的。 她说， 姐，你 知道苏 明玉吗 ？就是 《都挺 好》电 视剧里 的女老 大，我 就喜欢 她样子 的工作 ，有挑 战有成 就感， 有钱有 权，生 活自由 ，如果 给我那 样的工 作，我 会投入 我全部 的热情 。 听她说完，我尴尬的笑了笑。 其实每一个人都向往这样的成功 ，但这 姑娘却 本末倒 置了， 并不是 有了钱 有了权 有了成 就以后 才全力 以赴的 工作， 而是全 力以赴 工作， 投入了 自己的 全部以 后，才 有了地 位名望 钱财。 你要先投入，才会有收获，当你 真正投 入做一 件事后 ，会明 白两件 事：首 先你会 明白， 把一件 事认认 真真做 好，所 获得的 收益远 大于同 时做很 多事； 你会明白，有人风风火火做各种 事仍未 有回报 ，是因 为他们 从未投 入过。 从“做 了”到 “做” ，正如 “知道 ”到“ 懂得” 的距离 。 3 之前单位有一个姑娘，工作特别 拼命， 只要说 起她的 名字， 大家都 会赞不 绝口： 这姑娘 工作拼 命的程 度，连 男人们
