What are the 5 main pressures on biodiversity?

Five primary pressures—land-use and sea-use change, direct overexploitation of natural resources, climate change, pollution, and the spread of invasive species—are causing steep biodiversity loss.

What are the pressures on biodiversity?

The most significant current pressures are clearing, fragmentation and declining quality of habitat; invasive species; climate change; changed fire regimes; grazing; and changed hydrology. Most of these exert a high to very high pressure on biodiversity, and are worsening.

Why is biodiversity threatened?

The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. Climate change is predicted to be a significant cause of extinctions in the coming century.

What are the 5 important drivers of biodiversity loss?

The IPBES identified the five direct drivers of biodiversity loss as changing use of sea and land, direct exploitation of organisms, climate change, pollution and invasive non-native species.

What are the three pressures that lead to biodiversity?

Three major interacting drivers affecting all these pressures have been (and will be) climate, human population growth and the demands placed on the environment to support human lifestyles. It will be important to address all three of these drivers if pressures on biodiversity are to be reduced to desirable levels.

What is an environmental pressure?

Environmental pressures are factors that can cause environmental change in the marine environment.

What human activities threaten biodiversity?

D. 3 Humans depend on the living world for the resources and other benefits provided by biodiversity. But human activity is also having adverse impacts on biodiversity through overpopulation, overexploitation, habitat destruction, pollution, introduction of invasive species, and climate change.

What are effects of biodiversity?

Even though only a minority of humans realize it, biodiversity provides humans with food, water, oxygen, energy, detoxification of waste, stabilization of earth’s climate, medicine, opportunities for recreation and tourism, and many more things (Secretariat, 2000).
