Animal Destruction of the Environment - Example
A few goats had been set loose by sailors in the hope that their offspring would provide food for ship personnel in the future. Today, goats have taken over the islands. Some of the islands are now stripped of vegetation. Before the arrival of goats, the islands had no plant-eating mammals except turtles and iguanas that had low metabolism and ate little. Where goats have stripped everything, turtles and iguanas now face extinction. The don't eat much, but some vegetation is still essential for their survival. Turtles are also under attack from other human-introduced creatures: rats, dogs, and pigs dig up turtle eggs to eat. Iguanas are eaten by dogs and pigs.
How sad it is to see this devastation of this living museum of evolution.
Humans Are the Big Environmental Problem
We humans like to think of ourselves as superior to other species. We can do things with our brains that no other species can. This attitude of superiority has been called "speciesism."
By what standards do we measure the superiority of a species?
Humans are not immune to extinction. As the earth's population grows to the point where we have exhausted our resources or become so overcrowded as to encourage devastating plagues or wars, extinction becomes possible. More certain is that bacteria and bugs will be around long after we are gone.
We humans dominate the earth and the other living things in it. We exploit Nature to satisfy our desires. We whitewash our excessive desires by defining them as rights. We selfishly decide that our rights come first ahead of those of other species that have no rights. This viewpoint is then used to justify our abuse of the environment and the damage that we do to other species.
