The introduction of essay--Missy

Today,with the economy and technology develops at a dazzling speed,some species of wild animals have become extinct as a result of serious pollution,destruction of natural habitats and poaching.Some people think at the age of modern tcchnoloies,the existence of wild animals do not have any effect on social development.Thus,preventing them from dying out is a waste of resource.I totally disagree with this claim.The fact is that social development lead to our living enviroment at the same time is getting more polluted.One effect of this phenomenon is that there are no enough space for wild animals to survive.I will explain this issue and give some example to support my opinion.
