how can extinction affect humans? Well, according to new research published December 2 in Nature, the answer is yes—healthy biodiversity is essential to human health. 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.
What does extinction mean for humans? Human extinction is the hypothetical end of the human species due to either natural causes such as population decline due to sub-replacement fertility, an asteroid impact or large-scale volcanism, or anthropogenic (human) causes, also known as omnicide.
How extinction affect the world? 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 the loss of endangered species affect people? Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment. Without healthy forests, grasslands, rivers, oceans and other ecosystems, we will not have clean air, water, or land.

Debris from the explosion was thrown into the atmosphere, severely altering the climate, and leading to the extinction of roughly 3/4 of species that existed at that time, including the dinosaurs.

Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
what type of evolution occurs after a mass extinction?
As lineages invade different niches and become isolated from one another, they split, regenerating some of the diversity that was wiped out by the mass extinction. The upshot of all these processes is that mass extinctions tend to be followed by periods of rapid diversification and adaptive radiation.
why are blue whales extinct?
The blue whale was driven to extinction by commercial whaling in the 1800s and early 1900s.

How does the inner core act?
The inner core is solid because it is made of very dense, or heavy, materials – like iron and nickel. Even though it is very hot, these materials don’t “melt” very easily, so they stay solid. Answer 3: It turns out that many materials can be a solid at a higher temperature if the pressure is also higher.
