The Causes for Animal Disappearences

Approximately one-third of vertebrates were considered endangered from 1970 to 2006 (extinction). 50% of primates and 30% of amphibians are in danger of extinction. The number of ducks from Great Canadian ducks and ducklings has decreased from about 6 million to about 3.5 million (Martin). There are many reasons why their disappearance is disappearing, destroying habitats, using unethical hunting methods, famine and dehydration.

The concept of being at risk may be accepted by the scientific community, but the mechanisms that make animals disappear forever are still controversial. Charles Darwin's theory of evolution had decades of history, at that time scientists thought that animals would change over time, but Mr. Cuubier believes that animals are more or less normal from the beginning of animals I will. It's time. In the 1970s geologist Walter Alvarez noticed that the only indication of dinosaur extinction is the thin layer of clay and the dinosaur fossils can not be seen outside. This layer can be found all over the world. Walter could not comprehend the lifetime that the thin rock formations contained the annihilation of dinosaurs.

Do you know that the Earth is currently experiencing the sixth mass extinction of animals and plants? The last mass extinction took place 65 million years ago and the dinosaur has disappeared. It is important to understand what is going on in the world and talk about protection with your child so that you can continue to live a happy and healthy life on the earth we love. Stepwise extinction of individual species is a natural phenomenon, but the accelerated mass extinction that the Earth is experiencing was caused by humans. One fifth of the world's animals are on the verge of extinction due to human activities including destruction of animal habitats.

Millions of plants and animals are gone through the history of the earth. The main reason may be natural causes such as climate change and some catastrophic events. But recently there are some differences. Today, with the development of human civilization, human activities have a strong influence on the causes of endangered species. I am studying the cause of extinction of animals and plants and the plight of animals in danger of extinction and the effectiveness of their protection method. Introduction Humans are always the dominant force in our ecosystem and we have the ability to control and control all other organisms according to our wish to match our perfect technology and wisdom I have. I think humans and humans are the main reason why animals are harmed in our ecosystem today.
