As species disappear, infectious diseases rise in humans and throughout the animal kingdom, so extinctions directly affect our health and chances for survival as a species. ... The rise in diseases and other pathogens seems to occur when so-called “buffer” species disappear.
What happens to humans if animals go extinct?
The variety of life on Earth is called biodiversity . ... So, biodiversity is crucial for enabling us to survive and stay healthy. If we reduce the amount of biodiversity there is, by driving many species to extinction, then we cannot expect that nature will be able to keep providing these things for us.
What are the possible effects of extinction of species?
What are the consequences of extinction? If a species has a unique function in its ecosystem, its loss can prompt cascading effects through the food chain (a “trophic cascade”), impacting other species and the ecosystem itself.
How does extinction of species affect the environment?
The loss of a predator can result in what is called a trophic cascade , which is an ecological phenomenon triggered by a predator’s extinction that can also impact populations of prey, which can cause dramatic ecosystem and food web changes.
Can extinction be caused indirectly by humans?
Extinctions caused directly or indirectly by humans are occurring at a rate that far exceeds any reasonable estimates of background extinction rates, and to the extent that these extinctions are correlated with habitat perturbation, they must be increasing.
How will extinction affect humans?
As species disappear, infectious diseases rise in humans and throughout the animal kingdom, so extinctions directly affect our health and chances for survival as a species. ... The rise in diseases and other pathogens seems to occur when so-called “buffer” species disappear.

Can we prevent extinction?
Scientists tell us the best way to protect endangered species is to protect the places where they live . Get involved by volunteering at your local nature center or wildlife refuge. Go wildlife or bird watching in nearby parks. Wildlife related recreation creates millions of jobs and supports local businesses.
How do humans accelerate species extinction?
