I think endangered species of animals should be kept by the government to protect them because it is human who endangered the animals. Hunting, destruction of habitat and pollution are the major reasons why the number of animals is decreasing. Excessive hunting ruins the food chain, resulting lack of prey and extinction of animals. Land reclamation and deforestation are taking the homes away from the animals. Oil-spill and air pollution kill fish and birds. All of the damage are caused by human, so human should be responsible for the results.
