Some people say that the main environmental problem of our time is the loss of particular species of plants and animals. Others say there are more important environmental problems.

Environmental issue has been a heated topic since last century. Some argue that extinction of species has become a problem deserving a higher priority, while others believe there are other problems in need of instant action as well. I think protecting biodiversity is just part of our responsibilities towards environment.

There is no doubt that preserving as many as species is of great importance. Clearly, the more different animals and plants there are in one area, the stabler the ecosystem will be. If some core species disappeared, the local environment would collapse. That is why humans take various measures to protect endangered species from creating more nature reserves to imposing strict laws against the illegal trade in wildlife products.

Putting great importance on maintaining biodiversity do not mean other environmental problems should be neglected. Some global issues, such as pollution, have a detrimental effect on the whole world. To be more specific, water pollution is posing threat to health of all living creatures. Also, air pollution, like car fumes, lead to climate change. Take global warming for example. It causes the polar ice caps to melt, which might account for ever-rising sea level. Thus, there are many environmental issues requiring our intensive attention.

In sum, it is clear that we should make an effort to protect species in danger by establishing man-made habitats or combating poaching. More importantly, we need to take other problems into account as well because a balanced and sustainable environment cannot exist with only animals and plants.
