Innumerable ways depend on biodiversity, but because of human activity, species are disappearing quickly. The ecosystem services approach to conservation aims to quantify the value society places on the natural world so that decision-makers can understand the true cost of proposed development measures.
Since species are an essential part of ecosystems, assessments of their value in terms of services ought to be a part of every ecological assessment. However, estimating the worth of species is challenging and will never be complete. Benefits that arise suddenly or completely unplanned are some of the hardest for animals to evaluate.
The advantages that pertain to either supplying food or promoting leisure and other cultural activities are the most well-known. Over 90 million tons of fish are caught each year for human consumption globally, making up more than 8% of all animal protein consumed. Direct fishing employment totals close to 40 million individuals working full-time. More fish is exported from the developing world than all other agricultural products combined, with aquaculture making up nearly half of this total. Fish have a staggering commercial value, yet they frequently have value even if they are not sold. Take into account all of the tourists who visit coral reefs to view the vibrant fish. Think about recreational fishers as well (33.1 million in the U.S. and about 25 million in Europe). It is equally important to hunt terrestrial mammals or birds for food and for recreation. Millions of people go to other nations to witness mammals and birds.
One significant way to lessen risks to species while enhancing human well-being is through the ecosystem services strategy, which strives to create a more sustainable society. The advantages that come from ecosystems to people are called ecosystem services.
