It is a natural process of animal species to become extinct (e.g. dinosaurs, dodos etc.). There is no reason why people should try to stop this from happening. Do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge or experience....
How does a species become extinct? In the past a species would die off when it was unable to adapt to natural changes in its environment. In recent times, however, some species have become extinct because humans caused changes in the animal's environments.During the past 500 years, more th...
Biodiversity(生物多样性), or biological diversity, is a wide-ranging concept that covers all the different kinds of plant and animal species present on earth. Environmentalists believe that many millions of species exist. As all these living organisms are dependent on each ...
More species are joining the ranks of the extinct every year. Many scientists believe we are living through an episode of remarkably rapid extinction, on a scale that has been seen only five times in the last half a billion years.

Third, there is the possibility that the agnostids were parasites, living on and feeding off larger organisms. One reason that this seems possible is that there are many species of modern-day arthropods that exist as parasites, such as fleas, ticks, and mites. The agnostids might have lived ...
Many species of plants and animals would adapt or move to deal with the shift in climate, but many would become extinct. Some ecosystems are already changing drastically due to a shift in climate. The University of Alberta reports that much of what once was tundra in northern Canada is ...
But deducing the average life expectancy of an entire species can be more challenging. For one, past methods—such asanalyzing their earwax, which builds up each year like the rings of a tree—have required whales to be dead. In addition, commercialwh...
