生态灭绝

The envioronmental impact of the drought comprises the basification of the soil and groundwater's salt, surging pollution of the freshwater ecosystem ,the regional extinction of the animal speices.

干旱造成的环境影响有土壤和地下水的盐碱化、淡水生态系统污染加剧、动物品种的区域性灭绝等。

Today's earth faces many a problem of environm en t and ecosystem:"greenhouse effect",chemical pollution,acid rain,sand dust dev il,went short of water wealth,water and soil bereave,soil fallen into desert,spe cies eradication,forest demolish,etc.

今天的地球面临着许许多多的环境和生态问题，"温室效应"、化学品污染、酸雨、沙尘暴、淡水资源匮泛、水土流失、土地沙漠化、物种灭绝、森林破坏等等。

The cowman who cleans his range of wolves does not realize that he is taking over the wolf's job of trimming the herd to fit the range.

灭绝狼的猎人还没有意识到，他将必须接替狼来清理兽群，以保持生态的平衡。

In fact there are many factors threaten the existence of human, such as: forest demolishment, soil deserted, the destroy of ozonosphere, the increasement of ultraviolet radiation; global wcermerth and the raise of sea level caused by carbon dioxide and so on.

事实上，森林毁坏，水土流失，土地沙漠化，臭氧层的破坏，二氧化碳等气体增多，酸雨蔓延，水生生态破坏，水污染和水枯竭，物种灭绝等等，使全人类面临来自海、陆、空全方位环境退化的威胁。

A lot of people certificated the transgenic crops, simultaneously they also considered that the existence and development of target gene in natural environment probably change the species constitutes in nature ecological environment, pick up the deracination speed of many endangered species, make up the potential threaten and influence on the biodiversity.

许多人在认可转基因作物的同时，也认为，目的基因在自然环境中的存在和发展可能会改变生态环境中的物种组成，加快许多濒危物种的灭绝速度，对生物多样性构成潜在威胁和影响。

In the future I hope to be an ecologist.

将来我希望能成为一名生态学工作者，尽我的所能保护那些濒临灭绝的动物，治理荒漠化的土地，这虽是一项艰苦的工作，在其中会遇到许多的困难，我会尽力克服，为维护生态的平衡和稳定，和人类的可持续发展，作出自己的贡献。

Ecotourism — sustainable travel that is built around observing wild animals, not disturbing them — provides vital revenue for many local communities in wildlife-rich areas. And a steady stream of tourists can help convince people in biological hotspots like Madagascar or the Brazilian Pantanal that the local wildlife is worth more alive than extinct. For visitors, the prize is a firsthand study of the extinction crisis: you can't really understand what the world is at risk of losing, until you've come eye-to-eye with an indri lemur or a ploughshare tortoise.

生态旅游--可持续发展旅游，比如观看野生动物，但不打扰他们--为野生动物集中地区提供保护资金，固定的旅游团体的观光也会帮助当地居民比如马达加斯加和巴西潘纳尔更确信保护野生资源的观念，对于游客来说最大的收获就是亲眼目睹了濒临灭绝的危机，只有你亲眼看到一只大狐猴或一只乌龟的照片你才知道世界面临着每时每刻都在消失一些物种的危机。

The thick of the South African special-type and the East African Paranthropus species, size and silly to the more thick entirely plant-eating habits and ecological characteristics and human is a member of the system vary widely, is the side of human development Department of extinct about 100 million years ago.

南非特化的粗壮型和东非鲍氏种，体型较粗壮呆笨，完全以植物为食，习性与生态特点与人属系统的成员差别极大，是人类发展的旁系，约100万年前灭绝。

The analysis results indicated that the cause of wild animals was the population rampancy, species extinguishment, ecosystem decline and so on, but human disturbances were the original causes.

分析表明，兽害的成因有种群爆发、物种灭绝和生态系统衰败诸多因素，而人为干扰是各种现象的起因。

And, she said, the loss of one species can have a ripple effect on other species in the ecosystem.

并且，某种物种的灭绝会对生态系统中的其他物种带来连锁反应。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .
