should turtles go extinct? If sea turtles become extinct, both the marine and beach ecosystems will weaken. And since humans use the ocean as an important source for food and use beaches for many kinds of activities, weakness in these ecosystems would have harmful effects on humans.
What caused the mass extinction 250 million years ago? Siberian volcanic eruptions caused extinction 250 million years ago, new evidence shows. Summary: The Great Permian Extinction, which occurred approximately 250 million years ago, was caused by massive volcanic eruptions that led to significant environmental changes, new evidence shows.
Why is species extinction important? Healthy ecosystems depend on plant and animal species as their foundations. When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem.
Why is extinction a form of evidence for evolution? The extinction of species (and larger groups) is closely tied to the process of natural selection and is thus a major component of progressive evolution. In some passages of the Origin, Darwin seems to have seen extinction as part of natural selection; in others, as an inevitable outcome.

is yellowstone going extinct?

The answer is—NO, a large explosive eruption at Yellowstone will not lead to the end of the human race. The aftermath of such an explosion certainly wouldn’t be pleasant, but we won’t go extinct.
could the extinction of lions affect the grass population?
Every species is important to the health of an ecosystem. Removing one species can weaken a habitat, but if a keystone species is removed, an entire ecosystem could collapse. If large predators such as lions disappeared, herd populations would balloon, and grazers would eat up the grass.
when did bears go extinct in the uk?
Bears are thought to have become extinct in the UK in the early Medieval period, around 1,500 years ago. Wolves continued to roam the woodlands of England and Wales until the turn of the 16th Century and could be found wild in Scotland for up to 200 years after that time.

What whale was almost to extinction?
Eastern Pacific gray whales were hunted to near extinction in the mid-1800s and again in the early 1900s. Their blubber produced oil used for lamps. The animals were easily accessible to whalers because they remained close to the coast.

A column of hot gas and volcanic rock was ejected high into the air. This magma fell to the earth as fragments of frothy white pumice and volcanic ash.
What happens to the diversity of life during a mass extinction?
At the most basic level, mass extinctions reduce diversity by killing off specific lineages, and with them, any descendent species they might have given rise to. In this way, mass extinction prunes whole branches off the tree of life.
