What can be done against this problem? Actions that focus on the conservation of species include: specially protected natural areas; Types of protection and rehabilitation for threatened species; Preservation of genetic diversity. Actions that focus primarily on sustainable use include: the implementation of economic incentive measures; Inclusion of biodiversity issues in governance practices (in agriculture, forestry and fisheries). Actions that concern both conservation and sustainable use include: strengthening coordination between international agreements that affect biodiversity and resource use; Awareness-raising, communication and education; Improving our ability to assess the impact of ecosystem changes on human well-being; Humanity as a species with a huge population and habitat does not leave a suitable habitat for other species. It is necessary to intensively expand the area of specially protected natural areas for the conservation of endangered species, as well as strict regulation of the extermination of commercial species.
