Protecting the Wild Animals

Last week, I saw a very impressive documentary about panda. A professor studied panda in the early 1980s went to the wild life and kept trace of wild giant panda for many years. As a result, he found that it was human being that made these lovely animals die out. At that time, many people believed that giant panda became less because of the low rate of newborn babies. But it was not true. People cut trees for making profit at that time. Panda lose homeland and they lacked of food. Thanks to these valuable data, the government took the policy to protect the animals. So today, the number of giant panda is increasing. People realize the importance of protecting the environment and it is the best way to protect wild animals, they are the indispensable part of the nature.

上周,我看了一部令人印象非常深刻的关于熊猫的纪录片。一位教授在20年代80年代早期就开始研究熊猫,他到野外生活,多年寻找野生大熊猫的踪迹。结果,他发现,正是人类,让这些可爱的动物面临灭绝。当时,许多人认为,大熊猫变少是因为新生儿的低出生率。这是不正确。人们为了利益砍伐树木,熊猫失去了家园,也没有食物吃。多亏了这些有价值的数据,政府采取了政策去保护它们。所以现在,大熊猫的数量正在增加。人们意识到保护环境的重要性,这也是最好的方法来保护野生动物,因为它们是大自然不可或缺的一部分。

With the development ofscience and technology ,different kinds of pollution has been produced andcaused global concern recently.

As we know, people have beenliving on the earth for thousands of years, human activity damaged natural environment, such as excessive abuse of natural resources ,the sewage dischargedfrom factories ,the animal slaughter ,kinds of chemical fertilizers andgreen-house effect. All that is mentioned above has a bad impact on the eco-system .Now, many animals aredying out. We are suffering from unhealthy food and water, we are faced withharmful rays and global warming. It was ourselves who had made a series oftroubles. As you can see, we are the final victim.

Above all, if we human beings cannot recognize theseserious problems and try our best to solve them soon, we would finally lose theenvironment suitable for us to live. So, it is our duty to protect theenvironment ,but what should we do to protect it?

In my opinion, the first and important thing is tounite all forces ,that is to say---gather all hearts together. Next we shouldprotect and plant more trees, which can dispose of the dust in the air. As forfamilies, it is effective to ride bicycles rather than drive cars. Don’t litteranywhere as you like. In addition, sorting and recycling the rubbish also playan essential role in the protection of our earth. We’d better call on everyone aroundus to lead a low-carbon life, as it may make a difference to the environment.

Thus, it’s high time that we did something to improveour surroundings. Everybody should raise the awareness to protect our motherearth. Let’s appeal to more people to join us.

All in all ,there’s no doubt that keeping the balanceof human and nature ,we will benefit a lot.

我的家在广州的珠江边,听长辈说,那里以前是非常干净的,珠江里一点儿垃圾也没有,地上也是一点儿垃圾也没有,天空是那样的蓝,花草树木是那样的漂亮,空气是那样的清新……但我现在看见的环境,不再是像以前那样了,而是:因为工厂排出的废气和我们扔得垃圾,珠江变得臭臭的,水里还漂浮着各种垃圾和水生植物。因为我们乱扔垃圾,地上的垃圾随处可见。因为汽车排出得尾气,天空变的灰蒙蒙的。花草树木被人们和害虫破坏,使空气变得十分差……

为了不再出现这种环境,管理人员派工作人员去捞水里的垃圾,派清洁工人去扫地面上的垃圾,我们要种多一点树,要爱护花草树木……

我们也可以为保护环境做一些贡献。首先,不要做这样的事:浪费水、把垃圾扔进江河里、破坏绿化、伤害小动物……然后,可以做一些保护环境的事。比如说:用完水后把水龙头拧紧、看见地上有垃圾就进行清理、把能回收利用的物品卖给回收站或做成工艺品……

周围的环境和我们有着密切的关系,所以我们要保护周围的环境。小朋友们,行动起来吧,让我们把我们的家园变得更美好!

The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.

In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.

As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.
