By polution from areoplanes flying, ships passing by to go through or to visit the Antarctic and by sinking ships with 1000s of liters of diesel, drinks, oil, gas and many more.THE ANTARCTIC BEING SPOILED BYHUMAN INTERFERENCE
When humans destroy wild land to build homes, factories, shopping malls, amusement parks, garbage dumps, even to build a visitor center, store and restaurant in a park, the land is changed. The animals that once lived there, from the bugs that lived in the ground to the birds that ate them, all may disappear. Some can move to new home areas, but there are already other animals living there. There is not enough food, water or shelter for all of them. Many of the animals will die.When farmers spray chemicals on their crops to save them from pests (bugs and molds and things that eat the plants), the chemicals get into the water and into the soil. Bugs that do not hurt the crops die. The birds and mammals who eat these poisoned bugs may also die, or they cannot reproduce, or their offspring die young. Factories, automobiles, trucks and planes put chemicals into the air. The exhaust from their engines contains tiny specks of toxic chemicals that fall on plants, on the ground, and into the water. There, they get into the animals when the animals eat the plants, drink the water, or nest in the ground. These animals, too, can die or not reproduce.ANIMAL HABITAT DESTRUCTION
