The human race would not be far from extinction.
the earth will contaminate more than it is now that would provoke the extinction of lots of organisms
A+ False
If it happened instantly, millions of people and animals would starve to death.If it happened slowly over time, it was be a sad case of extinction, but the earth and humans would adapt.
This would be an incorrect premise, the most obvious answer being that Dinosaurs ruled the earth long before humans came along. Dinosaurs are now extinct and that would have been more than a mass extinction, it was global extinction.
According to theory, the extinction started when humans began to disperse across the globe about 100,000 years ago. As population increased, the need for food also increased. As a result people began using agriculture. While humans move across the earth as predators, other species become their prey. The Sixth Extinction Theory says that while people evolve, the world is dying- because our evolution is draining the world's resources. Therefore, the result is that humans are slowly destroying the Earth and we are the cause of The Sixth Extinction.

we the humans Remember that extinction is the rule not the exception. While humans currently play a part in the extinction of a number of species climate change, competition with other animals are primary factors in extinction. Other factors are a diminished gene pool and the inability to adapt to disease.
Humans can learn the importance of adaptability in the face of environmental challenges, the impact of mass extinction events on ecosystems, and the fragility of life on Earth. Studying the extinction of dinosaurs can also highlight the significance of conservation efforts to prevent future extinctions.
If there were no oxygen on Earth, most living organisms, including humans, would not be able to survive as oxygen is essential for respiration. Without oxygen, aerobic organisms would suffocate and eventually die. The atmosphere would likely become unbreathable, leading to widespread extinction of life.
The earth could be devestated by an extinction level event. I.e. planetary imact with a comet or large space body.
Seeing as how we humans live on earth, I am not sure what you mean.
