The expansion of agriculture plays a major role in biodiversity loss but this doesnt mean that we should grow less food. These are the top risks facing the world in 2020. The three greatest proximate threats to biodiversity are habitat loss overharvesting and the introduction of exotic species.

Biologists estimate that species extinctions are currently 5001000 times the normal or background rate seen previously in Earths history. E global climate change resulting from a variety of human activities. Habitat loss or degradation B.

The human population requires resources to survive and grow and those resources are being removed unsustainably from the environment. The growth of human populations consumption levels and mobility is the root of most of the serious threats to biodiversity today. Climate change may overtake habitat loss as the biggest threat to biodiversity over the next few decades.

But the greatest threat is that 80-90 of threatened species are under threat as a result of habitat loss or fragmentation. Habitat loss Invasive species Population Pollution Overexploitation HIPPO. The 5 Major threats to Biodiversity are.

According to most conservation biologists the single greatest threat to global biodiversity is A chemical pollution of water and air. The first two of these are a direct result of human population growth and resource use.

The first two of these are a direct result of human population growth and resource use. These threats have caused an unprecedented rise in the rate of species extinction. The human population requires resources to survive and grow and those resources are being removed unsustainably from the environment.

First it is rare that humans intend to make a species go extinct or to threaten biodiversity in some other way. Biodiversity is the biological variety and variability of life on EarthBiodiversity is a measure of variation at the genetic species and ecosystem level. How can the transition to a stabilizing population also be a transition to sustainability.
