Some people think that human needs for farmland, housing, and industry are more important than saving land for endangered animals. Do you agree or disagree? Why or why not? Use specific reasons and examples to support your answer.

Land for human needs or endangered animals.

As the rapidly development of the world’s economy, an increasing number of land has been used for farmland, housing and industry, which has intrigued a heated debate in recent years. Some say that human’s needs should be considered prior to others, however, I think we should have a special responsibility to protect the land that endangered animals can shade as home while considering human needs primary.

In the first place, we could not deny the fact that animals adapt very slowly to sudden changes in their environment compared with human’s special ability quickly to changing and hostile environments. For example, giant pandas used to live in only particular areas such as China where posses particular climate and resources for the development of them. Similar things are buffalo in America, tubulidentata could only be found in Africa, the list will go on. Reasons of these species are unique to these areas are lacking of strong adaptation, unavailable food and so on. Therefore many endangered animals can only live in one place, or in a specific type of place. Unlike animals, if humans need to live in a very dry environment they can use technology to locate and drill for water, or build pipelines to bring in water from outside. In other words, humans would think of ways to the best of their ability to improve the environment they want to live. Because humans are thus flexible and the ability to create, human should preserve that areas and make them the last choice of evading.

Moreover, as the increasingly great demand of land for economic development, there are many endangered animals have suffered from extinction, leading to the irreparable result of delicate ecological balance of an area. Food chain is an interdependent and restricts mutually of dynamic balance, any link upheaval may lead to disastrous consequences. If under normal circumstances, it won't appear such a vicious circle, unless there are external intervention. If humans need to cut down forests and use the land to grow corn, they might simultaneously destroy the habitats of a kind of birds that eats locust. The next year because the locust population can grow unchecked, locusts might destroy the entire nearby corn crop, Not only do the creatures lost their home, but also humans are harmed. The fact is clear, the ecological balance of many natural habitats is still not well aware of the importance of the balance, humans would be caught in their own trap.

In the end, we could not ignore the benefits that the endangered animals bring, particularly in the field of medicine. Scientific researchers have found that some animals can be used to manufacture new drug molecules but it failed because lacking of protection, as well as genes disappear that could have a effect on the crops of severe weather to overcome gene, even cause new plague, thus caused loss is we will never recover.

As I mentioned above, when making decisions about land use, we should bear in mind that humans should make an effort to use up all the available land before encroaching upon the habitats of endangered animal.
