Explain extinction of animals with examples.
Extinction of animals is due to two major factors:
•If some disturbances occur in their natural habitat due to which their survival is affected.
•Killing of the animals by human for several reasons.
We had observed that Dinosaurs get extinct many years ago due to the changes in their natural habitat. Due to the changes in their habitat they were not able to survive.
But if we have a look on the entire wildlife we will found that smaller animals have more threat of extinction as compared to bigger animals. These small animals include snakes, lizards, frogs, insects, owls and many more. They are more threatened as compared to large animals because they are more extensively killed by the humans without giving a second thought. We never thought of their role, results of their extinction and kill them.
Whereas killing of large animals is not as frequent as small animals so they are a bit safe.
