What will happen if species become extinct?

What will happen if species become extinct?

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.

What are the effects of extinction?

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.

Why is species extinction a problem?

The current extinction crisis is entirely of our own making. More than a century of habitat destruction, pollution, the spread of invasive species, overharvest from the wild, climate change, population growth and other human activities have pushed nature to the brink.

What are ways species can go extinct?

Species may become extinct because of changes in climate (i.e. the ice age), competition with other species, a reduced food supply, or combinations of all of these. Most natural extinctions are isolated events that happen over a fairly long period of time.

Can extinction be prevented?

Scientists tell us the best way to protect endangered species is to protect the special places where they live. Wildlife must have places to find food, shelter and raise their young. Logging, oil and gas drilling, over-grazing and development all result habitat destruction.

Why is it important to save endangered species?

The Endangered Species Act is very important because it saves our native fish, plants, and other wildlife from going extinct. From providing cures to deadly diseases to maintaining natural ecosystems and improving overall quality of life, the benefits of preserving threatened and endangered species are invaluable.

How does extinction of species affect ecosystem?

As species go extinct, they are taken out of the food chain. Animals that ate the newly-extinct species have to find new food sources or starve. This can damage the populations of other plants or animals. Furthermore, if a predator goes extinct, its prey’s population can proliferate, unbalancing local ecosystems.

What effect does animal extinction have on humans?

Scientists have also discovered links between the incidence of West Nile virus and hantavirus and local reductions in biodiversity. Animal extinctions may also rob humans of valuable medical advancements. Many different species have unique bodily processes that can offer insight into curing human disease.

How the extinction of animals affect humans?

Do animals go extinct naturally?

Extinctions are a normal part of evolution: they occur naturally and periodically over time. There’s a natural background rate to the timing and frequency of extinctions: 10% of species are lost every million years; 30% every 10 million years; and 65% every 100 million years.

How can we save wildlife from extinction?
