Why is biodiversity in danger?
Biodiversity is subject to many threats. The greatest is probably habitat destruction and fragmentation. But there are many other threats to biodiversity. Over-consumption by humans –by hunting, fishing, or collecting from the wild– threatens many species.
What are 5 benefits of biodiversity?
Support a larger number of plant species and, therefore, a greater variety of crops. Protect freshwater resources. Promote soils formation and protection. Provide for nutrient storage and recycling.
Which of the various threats to biodiversity do you think will be most difficult to stop?
The hardest to justify is poaching (which is illegal). Deliberately killing an animal (especially one that is endangered) just for money, trading, and creation, and out of season is selfish and unnecessary.
Why is biodiversity a good thing?
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.
