Over-exploitation of Species.
Global Warming and Climate Change.
Why is it important to maintain high levels of biodiversity?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. … A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
What are the challenges of biodiversity?
The key pressures driving biodiversity loss are overexploitation of species, invasive alien species, pollution, climate change, and especially the degradation, fragmentation, and destruction of habitats (7).
What is the #1 threat to biodiversity of plants?
The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and introduction of exotic species. The first two of these are a direct result of human population growth and resource use. The third results from increased mobility and trade.

How humans are destroying biodiversity?
The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
What is one action you will take to reduce threats to biodiversity?
Attract “good” insects by planting pollen and nectar plants. Maintain wetlands by conserving water and reducing irrigation. Avoid draining water bodies on your property. Construct fences to protect riparian areas and other sensitive habitats from trampling and other disturbances.
What are the major threats to wildlife?

Why is biodiversity important 5 Reasons?
Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
What is destroying biodiversity?
Scientists have called the degradation of Earth’s biodiversity in the modern era “biological annihilation” and the sixth extinction — and we caused it.
