Habitat loss from exploitation of resources, agricultural conversion, and urbanization is the largest factor contributing to the loss of biodiversity. The consequent fragmentation of habitat results in small isolated patches of land that cannot maintain populations of species into the future.
What is the biggest threat of biodiversity to you why?
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.

Can we survive without diversity?
Consisting of animals, plants and habitats, biodiversity is essential for our everyday needs including water, air, shelter, food and medicine. … There are three essential levels of biodiversity – genetic diversity, species diversity and ecosystem diversity.
What are the effects of biodiversity loss?
Biodiversity underpins the health of the planet and has a direct impact on all our lives. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease, and where fresh water is in irregular or short supply. For humans that is worrying.
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.

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.
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.
