为什么先有鸡在有蛋用科学道理解释

Answer 1

Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.
In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.
Only if we human beings take some drastic measures can wild animals be preserved.

我认为是先有蛋，因为在地球还处于火山不断喷发的时代，产生了最简单的有机物，然后就产生了细胞，就相当于蛋就好像受精卵一样，然后就组成了单细胞生物，相当于鸡，后来环境不断变化，单细胞生物不断进化，分裂，就逐渐形成了多细胞生物，更适应环境。从海洋到陆地，形成了生物的多样性。谢谢，这只是我个人观点。 高一学生

Answer 3

Animals are people's friends. But many wild animals are facing the danger of dying out(灭绝)，because the environment that they are living in has changed greatly. For example, their living area is becoming narrower(狭窄的) and narrower because of the development of cities and pollution. They have no room to live in except the zoo.(除了动物园,它们没地方可住了) And many wild animals now can't find enough food to eat. At the same time, man is killing off(杀尽) animals just for getting their fur, skin, teeth and meat.

People should realize how serious the situation is and something should be done to protect(保护) the animals. We are supposed to set up some nature reserves(自然保护区), so that animals can live freely. Besides, people should not be allowed to kill the endangered animals or eat their meat. We should do something to make our world cleaner. Fresh air, clean water and grass are all important for animals. The death of the endangered animals will bring a disaster(灾难) to human beings.(人类)

Human is the creature which is the closest to God. It means we have more duties and rights for this world. Biological diversity have been damaged by the developing of modern society, which have threatened to the life of animals as well as the life of human.

The extinction of animal is an alarm to human beings. With the process of human civilization, our life become more and more comfortable and convenience, it may be a good news to man but a bad news to animals. Exhaust gases are emitted to the atmosphere, which react with each other and combine with water vapor ,and finally lead to form acid rain. Acid rain fall into lake and kill the frogs and the fishes. Time will tell you, although the recent acid rain may not directly harm to us, we would not escape from the doom if we ignore the alarm from animals. We are a part of the food chain. Most of the human’s diets come from animals, which means the dangers that are threatened not only the animals but also the human. Several serious diseases from animals have brought us into the hell in the beginning of the new century. For example SARS, the horrible disease has killed thousands of people which was attributed to eating the ill wild animals. As the end of the food chain, we should spend money on preventing wild animals which is a confession from the evil consequence.

I believe no one would neglect the alarm from animals if he recognized it, no one would be of parsimony with the money if it is used in preventing himself. Development of society and preventing animals are our right and duty which also need us to balance.
