The environment is very important to human beings, but some people dont care for the environment, also do not know the importance of environment for human.

You see, many people dont care for the environment, they throw garbage everywhere, some people think: what is a garbage? However, many a mickle makes a muckle, and neighborhood became a dump the most beautiful place. Some people cut trees to build houses dig mountain, beautiful hill into desert and house. Some people dont have time to cook, just walk outside in the fast-food restaurant to buy rice, I eat, after dinner they also put the disposable lunch box, disposable chopsticks thrown to the ground. Some people in order to display their own home is very rich, driving a car on the road around. They didnt realize that both environmental pollution and waste of energy. Some factories take some sewage, smoke into the rivers and the sky.

For the sake of our environment, for the sake of our life, I want people to throw garbage into the trash can, little cut down a tree much afforestation, try to go home for dinner. Will exhaust waste water is introduced into the ground, dont show how rich, attention should be paid to energy conservation and emissions reduction.

Believe in you in the near future, with the help of our city will be more beautiful!

环境对人类十分重要,可是有些人不爱护环境,也不知道环境对人类的重要性。

你看,许多人都不爱护环境,它们随地扔垃圾,有些人认为:一个垃圾算什么?可是积少成多,小区里最好看的地方成了垃圾站。有些人为了建房子挖山砍树,美丽的小山变成了沙漠和房子。有些人没时间做饭,就在外面快餐店买了饭一边走一边吃,吃完饭后他们还把一次性饭盒,一次性筷子丢在地上。有些人为了展示自己家里很有钱就开着跑车在路面上到处跑。他们没有意识到既污染环境又浪费能源。有些工厂将一些污水、浓烟排入江河和天空。

为了我们的环境,为了我们的生活,我希望人们可以把垃圾扔进垃圾桶,少砍树多造林,尽量回家吃饭。将废气废水引入地下,不要展示自己多么有钱,要注意节能减排。

相信在大家的努力下不远的将来,我们的城市会更美!

我们每个人都有一个、两个、三个,甚至四五个理想。记得托尔斯泰曾经说过:理想是指路明灯。没有理想就没有坚定的方向;没有方向就没有生活。

为什么我要当动物保护者呢?第一:我对动物特别有同情心,比如一些流浪狗、流浪猫之类的流浪动物,我会趁爸爸妈妈离开的时候给它们一些食物吃,一开始它们会半信半疑,(因为它们常常被一些卖狗肉,参猫肉的,引诱,然后就……)于是我就走的远远的,在一个隐蔽的地方看着它们吃完了,我才离开。第二:我对动物特别了解,我几乎每天都看快乐宠物,里面会有些关于宠物资料。比如我家的小泰迪——阿酷,我可以看阿酷的身体动作来判断它想要干什么。

如果再过上20年,30年,我真的当上动物保护者,我一定会禁止人们掠杀猫、狗之类的流浪动物,探索出尼斯湖水怪的真正面目,研究出治愈狂犬病的药物,还有最重要的事情就是要保护好动物,禁止虐杀动物,随便给动物喂食……要保护好环境,只有这样动物才能生存下来,如果没有动物我们也无法生存的,比如说牛,帮助人类耕田。

虽然我还没有当上动物保护者,但我也算半个动物保护者了,但是我还是要呼吁大家保护动物,从自己做起。

青蛙被称为:“庄家的保护神”。它的眼睛圆溜溜的,似乎里面装满了薯片,如果里面真的有薯片,那我一定要把它一扫而光,它的眼睛也炯炯有神,似乎能看透人类内心的想法,它的舌头卷卷的,好像是一卷胶带,捕捉害虫的时候,舌头长长的,看上去像一卷大大卷。它穿着一身草绿色的衣裳,穿上这件衣服以后,像一位上场的将军,威风凛凛,很有气势。青蛙专门捕捉苍蝇、蚊子、小飞虫,一只青蛙每天大约吃六十只害虫,这是一个渺小的数字,但是它的本领已经令我有些刮目相看,虽然它不像蜻蜓的本领每小时吃二十只苍蝇或八百四十只蚊子,那么大的数目。但是有一点它与蜻蜓相同:它在水中嬉戏,也会捕捉害虫呢。

今天,我读了《白耗牛》一书,受益匪浅。《白耗牛》讲述的是这样一个故事:在一个牧场里,丢失了一只珍贵的耗牛。这时,个叫贡嘎的学生,要为玛尔吉阿婆找回这只白耗牛。他翻山越岭终于从一个守林人那里了解到白耗牛被偷到了长岭山的牧场,还得知牛贩子康劳要杀白耗牛。他只身勇闯虎穴,终于从康劳的手里抢回了白耗牛。

读了这个故事,我想:“连个学生都能这样为国家保护珍贵动物,而现在很多人却随便捕杀野生动物,破坏环境,使动物们生存受到了威胁。”

我曾在电视上看到这样组镜头:非洲草原土,横七竖八地躺着被割去象牙的非洲象,周围一片鲜血;一条肮脏的冒着白泡的河流中,漂着一条一条死鱼;还有被关在笼中的猴子……

记得有一次,爸爸带我们到饭店吃饭,我忽然看见了饭店一角关着两只山甲,鱼池里还有中华鳃,这些可是国家保护动物啊!怎么能被吃掉呢?

这不禁让我回想起了我看过的一部纪实影片:一只活泼可爱的小猴子被关到了一个特别的笼子里,只露出一个脑盖来,侍者拿出锤子对着脑盖敲了几下,小猴的脑盖便开了,而那些可恶的客人竟然用热水烫过的勺子舀着猴脑吃保护动物作。小猴在那里大声惨叫着……

这是为什么?人类本应与自然和谐共处,但有些人却为了金钱,不择手段,屠杀手无寸铁的动物。从此,大自然的生态平衡被破坏了。

地球已经千疮百孔了,如果我们人人都像贡嘎一样,那么很多珍稀的动物也不会灭绝,动物们也不会向人们苦苦哀求了!

朋友们,快清醒吧,动物是人类的朋友!我要大声呼吁:“保护动物,人人有责,让我们共同保护我们的家园吧!"

As is known to all, waste on campus has become a more and more serious problem. We can easily see many students dump a lot of food in the garbage can. Some students spend thousands of yuan buying fashionable clothes and so on.

The negative effects of waste can be shown in the following aspects. In the first place, it makes some students dependent on their parents for money, which is harmful to their development.

If they don’t learn to support themselves, they will be “useless people” when they graduate. In the second place, it is not easy for our parents to arrange for our schooling. Last but not the least important, there is no denying the fact that our country is still poor. There are many people who cannot go to university and many poor people still need our help.

As far as I am concerned, I should set a good example to reduce waste on campus. First of all, I will refrain from wasting anything, from food to stationery. What’s more, I’m determined to call on more schoolmates to fight against waste. Only through these measures can we hope to reduce waste on campus.

There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.

Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."

Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.
