The Ozone Layer on its Way to Recovery

This article is about the ozone layer and how it is recovering faster than scientists expected.  Scientists discovered a problem in the ozone layer in the 1970’s. The ozone layer protects the Earth from the blazing Sun.  The problem with the ozone layer was that it had been getting thinner.  Today we know that this was caused by chlorofluorocarbons a chemical that was used in Styrofoam and other products. The ozone layer is far above the Earth’s surface. After discovering the source of the ozone problem, one-hundred and ninety-six countries signed the Montreal Protocol.  The purpose of this agreement was to reduce the use of chlorofluorocarbons and restore the ozone layer.  A report published by over three-hundred scientists from the United Nations recently announced that by 2050 the ozone layer will be recovered to the 1980 level.  I think that this is very important because it will help stop global warming.

Summary of The long-distance voyage of Plastic

The article, The long-distance voyage of Plastic, is about plastic in the Atlantic Ocean.  For twenty-two years, scientists have been researching the amount of plastic by collecting samples from the ocean surface and studying them.  They were surprised to learn that the amount of plastic didn’t decrease or increase over twenty-two years.  That surprised me because I think we use more today than we did twenty-two years.  The marine biologists think that either the fish are eating the plastic, it’s sinking to the bottom of the ocean or it is too small to collect in the net.  I think all of these may be true.  Obviously all of these options are extremely bad for the environment, the fish that live in the Atlantic Ocean and even people who eat fish.  Dr. Kara Law and her colleagues researching this serious problem. In the mean time, I encourage everyone to recycle their plastic containers and help save our oceans.
