Sample Custom Essay or Term Paper on Biogeography

... There are several causes of the island species extinctions. Major of them are the predatory by humans, spread of diseases and habitat loss. Habitat loss in its turn is caused by the technological development of the society alongside with the insufficient environment protection. Islands being the isolated ecosystems are especially vulnerable to the ecological misbalance.

Islands species continue to be lost. Though the situation is alarming it is not critical. The island species can be protected and are being protected. All the conservation measures like habitat protection, pest and predator control as well as hunting control are easy to implement on the isolated islands. It is easier to observe and regulate the ecological balance of the island. The pollution is controllable at the isolated area.

The species may be re-insulated by transferring them to other islands with more ecologically friendly environment. All these measures require urgent human actions..

It is time for humanity to pay its debts back to the Nature.
