eocene和另一個地質(zhì)時代生物大滅絕的對比
英國經(jīng)濟在十八世紀顯著擴張，特別是隨著工廠制造業(yè)的發(fā)展到了本世紀中葉，它已經(jīng)開始改變英格蘭北部的景觀。在17世紀70年代，一位紳士說:“從制造商的建立起，我們看到哈姆雷特村逐漸發(fā)展為村莊，村莊逐漸發(fā)展為城鎮(zhèn)。”本世紀下半葉，制成品的產(chǎn)量翻了一番。棉花制造業(yè)領(lǐng)先:從1750年到1770年，英國棉花出口翻了一番。緊隨其后的還有羊毛和羊毛織物、亞麻、絲綢、銅、紙張、餐具和蓬勃發(fā)展的建筑業(yè)。煤代替木頭作燃料。
在世界上2.4%的新鮮水域中，將近90%被冰川、冰帽和雪地所束縛。在冰川之后，下一個最大的淡水水庫是地下水。地下水是美國近40%的農(nóng)業(yè)和家庭淡水的來源。近一半的美洲國家和大約95%的農(nóng)村人口依賴地下水來飲用和其他家庭用水。這些資源的過度使用導致了多種問題，包括水井和天然泉水的干涸以及濕地、河流和湖泊等地表水特征的消失。
這可能看起來令人驚訝，但沙漠動物很少做出特殊的身體適應沙漠環(huán)境。相反，它們通過恰當?shù)纳锘顒訒r間來生存，半水棲和水棲沙漠動物就是最好的例證。
兩棲動物的水生特性使它們看起來不像是沙漠居民。繁殖需要開闊的水域，雌性和雄性分別在那里存放卵子和精子，然后發(fā)生受精。受精卵的發(fā)育發(fā)生在水中，有鰓和無腿的幼魚必須在水中游泳和進食。只有成年動物能在陸地上生存，但發(fā)育不良的肺和透水性的皮膚限制了它們在潮濕的棲息地生存。兩棲動物戰(zhàn)勝了困難，它們并非擁有極其適應性的結(jié)構(gòu)或有機過程，而是擁有在短暫的有利條件下進行活動和繁殖的生命史。沒有比美國南部沙漠中的鐵蹄蟾蜍更能說明這種能力的兩棲動物了

Certain animal and plant species are native to one specific area and are found nowhere elsein the world. lf such species once lived over larger geographical areas in the past, they areknown as paleoendemic species , Originally, the paleoendemic species was part of a largeplant or animal population that was spread out over a wide area, but at some point itbecame separated from the larger population. Environmental conditions then caused thelarger part of the species population to die out and become extinct. However, the smaller.separate paleoendemic population was able to survive in its isolated location.

1.對環(huán)境有利。因為會對害蟲有抵抗力，可以不用殺蟲劑。
2.幫助農(nóng)民獲得經(jīng)濟收益，改善他們的經(jīng)濟水平。
3.營養(yǎng)價值高，含有某些營養(yǎng)物質(zhì)，例如某種特定的維生素。

1.會產(chǎn)生物種間的基因交流，對生態(tài)環(huán)境造成的影響不可控
2.轉(zhuǎn)基因作物的種子需要付費，貧窮的農(nóng)民還是買不起，費用也不一定能賺回
3.轉(zhuǎn)基因作物中的營養(yǎng)物質(zhì)只是一部分營養(yǎng)素，還不如吃各種蔬菜水果營養(yǎng)均衡。
Your professor is teaching a class on sociology. Write a post responding to the professor's question.In your response, you should do the following.- Express and support your opinion.- Make a contribution to the discussion in your own words.An effective response will contain at least 100 words.Doctor Achebe:As countries work to reduce emissions and protect the environment, many governments are encouraging the adoption of electric vehicles through new policies. This week we will discuss ideas for policies that could promote electric vehicle usage. In your post, I would like you to address this question: What policies should the government implement to promote electric vehicles for environmental protection?Claire:More charging stations are key to getting people to buy electric cars. It's frustrating when you can't charge your car. The government should offer big tax credits to businesses to build charging stations. If charging spots are everywhere, range anxiety will go away and electric car sales will take off. We need that to help the Earth.Paul:The government needs to create entire highways just for electric cars. These special roads could have charging stations along the way so range anxiety disappears. Exclusive electric highways would show electric cars are the transportation of the future. We'd see tons more Teslas on the road helping clear the air.
