Why would be extinction affect us?

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.

Why should we not save endangered species?

The reason species are dying off so fast, is because of our great effect on the environment. Although we cannot save every species that becomes extinct, we can save the environment that we live in, to prevent every species from dying off. Not many species can survive in a damaged and polluted and damaged ecosystem.

How does extinction affect biodiversity?

The species that are unable to adapt to environmental changes become extinct. This reduces biodiversity. Species that are too closely interbreed can go extinct as mistakes in the DNA accumulate in the population. All forms of extinction cause reductions in the remaining biodiversity .

What will happen to the world after the human extinction?

There will be carnage of the other species that were left on earth after the human extinction. The most important power plants are the nuclear plants. Although these stopped operating and providing power, there will be a massive nuclear explosion after months.

Will humans ever go extinct?

The short answer is yes. The fossil record shows everything goes extinct, eventually. Almost all species that ever lived, over 99.9\%, are extinct. Some left descendants. Most – plesiosaurs, trilobites, Brontosaurus – didn’t. That’s also true of other human species. Neanderthals, Denisovans, Homo erectus all vanished, leaving just Homo sapiens.

How many species are being driven to extinction each year?

Harvard biologist E. O. Wilson estimates that 30,000 species per year (or three species per hour) are being driven to extinction. Compare this to the natural background rate of one extinction per million species per year, and you can see why scientists refer to it as a crisis unparalleled in human history.

What would happen if there was no humans on Earth?

“Nature will break down everything eventually,” says Alan Weisman, author of the 2007 book The World Without Us, which examines what would happen if humans vanished from the planet. “If it can’t break stuff down, it eventually buries it.”
