nation, but are free, open territory to be enjoyed and shared. However, too often nations are very aggressive in taking the resources the ocean has to offer. A tragic result has been the systematic hunting of whales for whalebone, blubber, and oil.

D - High above the Earths atmosphere there is a thin veil called the ozone layer, which protects the Earth from the suns destructive ultraviolet (UV) rays.
This protective layer is being damaged by chemicals, which are released into the atmosphere by the daily use of industrial and household products as refrigerators, air conditioners, cleaning chemicals, food packing, etc. The chlorine attacks the ozone molecules, thinning or even making a hole in the ozone layer. This hole allows more UV rays to penetrate to the Earth.
Overexposure to UV rays can increase the risk of skin cancer, weaken the immune system, and damage the retina.
Not only are humans at risk, so are animals, plants, and the environment in general.
