Why are island habitats said to be in peril ?

D oyou know Why are island habitats said to be in peril because Humans have encroached upon nearly every habitat on the planet. A habitat is a place where an animal lives, providing it with food, water, and shelter.
Islands are expecially vulnerable to threats because of their isolation. When people settle on islands, they destroy the unique habitat that exists there. All over the world, coral islands are being threatened by climate change, overfishing, and pollution from sewage. Weather-related damage to reefs occurs frequently, especially from powerful waves of hurricanes and cyclones.
An excellent example of threats to an island’s habitat can be seen in the Galapagos Islands. Illegal fishing, and the demands of more than 160,000 tourists each year threaten this irreplaceable ecosystem, and the people who depend on it for their livelihoods.
Other examples are Mauritius, which has practically no natural woodland left, and Madagascar where forests have been destroyed to make land available for pasture for cattle.
