Ecosystem Service is a kind of benifits which human get directly or indirectly from the nature.It includes many things, from the fresh air and water we all know to the process of circulation in the nature quietly which's importance we have not learned until recent years.Though organisms and inorganic bodies compose ecosystem together, maybe the humans are the biggest beneficiaries.Relying on Ecosystem Service,human beings could develope rapidly in a short period after a long but steady transition.In other words,the development of human economy and society is based on the consumption of Ecosystem Service.And becouse of the lack of recognition of nature ,excessive consumption has caused severe environmental problems,such as more and more species of living things are at risk of extinction or endangered circumstances,and serious pollution of the environment.WIth the depth and scope of problems' influence enlarging and human's consciousness advancing,there are more and more novel ideas being put forward,and more studies been explored.VMR is a good example.It's hard and endless to seek Ecosystem Service,but we will never stop.
