Some people think that only those animals that are useful to humans should be protected. Others believe that all animals should be protected. Discuss both views and give your own opinion.

21OpinionsOponions differ over whether 3protectingprotecing those animals that are beneficial to humans or all animals should be preserved. 4While the former can avoid the extinction of a certain creature in a short time, I favour the latter because its long-5termtrem benefits to the biodiversity and 6preservationpreservetion of the most species in our planet.

Those who support only protecting useful animals often 7point out that our budgets are limitedpoint to our budgets are limited, and we should 8concentrate our funds on protectingconcentrate our money to protect creatures that directly benefit us in fields of scientific research, health care and industrial 9productionproducation. However, protection provided to those which do not benefit us directly will reduce budgets to these creatures. In contexts where the certain creatures are extremely 10endangered and its connectionendangered and the its connection with other animals is weak, this approach can use limited budgets to ensure its safety. For example, pandas used to be a seriously endangered animal, but after gaining the most concentration from Chinese people and protection of governments, its population increased quickly to over thousands.

Nevertheless, the case for 12protectingprotect all animals is stronger. Every creature is an important part of our biological system. They have their own missions in 13maintainingmaintainning the stability of environmental balance. Any creatures which seem to be useless may have positive or 14negativenagetive influence to other animals. They protect the biological balance 15togethertogerther.

For example, 17AustraliaAustrilia used to hunt wolves to protect 18rabbits, leading to a dramatic increase in the number of local rabbits.robbits, it leads to dramatic increase of the number of local robbits.

Therefore, the long-term benefit of protecting all animals to 22maintainmaintian the biological system outweighs the short-term protection for only useful animals. Inconclusion, both positions offer clear benefits; on balance, however, protecting all animals is preferable because it maintains a sustainable biological system and sources.
