Why extinction occurs?

Answer 1

Extinction happens because of one of three reasons;

1- the animal can not adapt to the environmental changes if they are occurring.

2- the animal has competition with another species that either takes over their territory or wiping out their main source of prey.

3- if this relates to modern times, extinction may happen because man has destroyed the species habitat, hunted the species, or wiped out the species main source of food.

One of the most common threats to extinction today is of global warming, and the devastating effects its having on the earth and the climate. Global warming is slowly warming up earth, slowly melting the north and south poles, causing the changes in sea level and temperature. immediately effecting the animals across the world.

Answer 2

many reasons most of them is humans -

we build houses where most animals live and don't give them a new home

think of it this way = you're an endangered animal, you live with your family in a nice place on the west coast of the U.S.A, generations of your species have lived here, humans move in, no problema all animals can be friends right?, you stay even when they hunt and shoot you for sport, you accept that wolves and predators have to eat yet here humans hunt for no eating purpose or any purpose but joy, finally they force you to move, you move east, keep on moving east as more human colonize the earth, eventually you get to the east coast, no where to go, you head back west, but for some reason humans thinks that you're the invader and a pest when its really vice-versa, so they go get poison, traps, guns, etc. and shoot you and you're family off the face of the earth. soon bye-bye beautiful species that were here first.

this is why extinction is happening. because of humans.

p.s. this is the U.S. I'm not even counting the species that live only on islands like the Galapagos Islands or madasgascar. i mean where are they supposed to go?!?! are they supposed to grow fins and swim or something?

Answer 3

There have been five mass extinctions that mark the changes is epochs.

There is a great deal of speculation as to what caused each, but given that the most recent was ~ 65 million years ago, we cannot be certain.

Evidence points to volcanic eruptions or massive meteors that struck the earth setting off cataclysmic events.

On smaller scales, destruction of habitat or food source can be events that lead a species to extinction.

Answer 4

Extinction can happen when people or animals start killing other animals species, and if they keep on killing them, their popularity of their species go down. And soon one day their species will be gone forever, like the dinosaur species.

Answer 5

Extinction can occur for a number of reasons. Some of these include environmental changes that are not suitable for the animal, and inability to find food.

Answer 6

Exstinction happens when a type or come of species or organism or things dies out completely and nothing is left of that kind

Answer 7

Animals/plants go extinct because a factor (environment, disease etc) has killed off one species. Extinct animals/plants do not exist in the world anymore. :)

Answer 8

because of hunters, expansion, pollution, death
