Why does biodiversity need to be conserved




















This provided food and shelter for hundreds of other animal species; insects, mammals, birds, birds of prey, amphibians and fish. With more plants, trees and animals the soils improved and became stronger - less prone to erosion, drought and flooding.

The more biodiversity an area has, the healthier it is because it supports a large number of animal and plant species. Understanding biodiversity is important for the environment, as well as people and medicine as we will explore -.

Why do we need to conserve biodiversity? Why is biodiversity necessary for the stability of the planet? It may not be self-evident, so here are five reasons. Conservation researchers Paul R. Losing one might not be a disaster, but each loss adds to the likelihood of a serious problem.

Whether in a village in the Amazon or a metropolis such as Beijing, humans depend on the services ecosystems provide, such as fresh water, pollination, soil fertility and stability, food and medicine. Ecosystems weakened by the loss of biodiversity are less likely to deliver those services, especially given the needs of an ever-growing human population.

Without conservation methods in place, this could be the fate of many more ecosystems. Research indicates that there is a close link between disease outbreaks and the degradation of nature. Seventy percent of emerging viral diseases have spread from animals to humans. As the global wildlife trade continues and development projects expand deeper into tropical forests, humans are increasing their exposure to wild animals — and the diseases they may carry.

This shows that we must take care of nature to take care of ourselves. Deforestation is also accelerating climate breakdown , which in turn may boost the spread of disease by allowing disease carriers like mosquitoes to extend their geographic ranges and infect new populations of humans. In a landmark study published in , a group of researchers led by Bronson Griscom, who researches natural climate solutions at Conservation International, discovered that nature can deliver at least 30 percent of the emissions reductions needed by to prevent climate catastrophe.

Protecting biodiversity plays a crucial part in achieving these emissions reductions. The destruction of forest ecosystems is responsible for 11 percent of all global greenhouse gas emissions caused by humans, so conserving forests would stop the release of these gases into the atmosphere.

Trees and plants also store carbon in their tissue, making it even more necessary to protect them.
