Explanation:

    More than 60% of the resources and services provided by the planet's ecosystems are degraded, and the consequences of this destruction could worsen significantly over the next 50 years, warns an international study published in 2015. Freshwater, fisheries, and air and water regulation Water, regional climates, natural disasters and pests are the most endangered natural resources and services, says the Millennium Ecosystem Assessment, prepared by 1,300 scientists from 95 countries. Degradation of 15 of the 24 ecosystems studied increases the likelihood of abrupt changes that can severely affect the well-being of all biodiversity on the planet, such as the emergence of new diseases, sudden deterioration in water quality, the collapse of fishing grounds and changes in regional climates.

    The extinction rates of animal and plant species are increasing on an unprecedented scale. The average abundance of native species in most major terrestrial habitats has fallen by at least 20%, mostly since 1900. More than 40% of amphibian species, almost 33% of corals and more than one third of all mammals are threatened. .
