The most common question about the envinroment today is whether or not we can reduce gas prices without impacting the environment in a negative way. Some people think we can drill for more oil and lower gas prices, while others point out the environmental implications.

National Geographic News has recently written an article regarding the ozone layer. They have reported this month that it appears that the ozone layer seems to be healing.

The ozone layer is approximately 15 to 30 kilometers above the surface of the Earth. It blocks most of the suns ultra-violet waves. These UV rays are very dangerous, for example they contribute to the cause of cancer. A hole in the ozone layer is very dangerous.

It is thought that CFC's are what caused the hole. CFC's (chlorofluorocarbons) are very dangerous to the atmosphere. They can linger for decades. Chlorine steals the ozone molecules by stealing oxygen atoms. This is what creates the hole.

It is believed that due to international efforts the ozone is now repairing itself. The hole seems to be getter smaller.

"Global ozone dropped a little bit [after CFCs were banned], but the good news is that if we had done nothing, it would have gotten really, really bad."

I would echo the previous thoughts about the most recent oil spill in the Gulf of Mexico.  Another current topic regarding the environment would be to assess the impending legislation waiting to be passed regarding it.  Given the massive demands of health care legislation and the impending debate on immigration that has been fostered by the recent passage of the Arizona law, the question of how environmental legislation would be treated is a valid one.  This issue is being monitored by many watchdog groups that believe that this current administration has great aspirations to help with the environment situation and to not do so could be disastrous.  A current topic about the environment would thus be to assess whether or not impending legislation can be passed in order to remedy the problems within it.

Since four million gallons of crude oil are now in the Gulf of Mexico as a result of the explosion of an offshore British Petroleum oil rig that has yet to be capped, the ocean environment as well as the shorelines of Louisiana, Alabama, Mississippi, and even Texas are threatened.  The fishing industry of Louisiana has come to an abrupt halt and birds, sea turtles, and other creatures of the sea are threatened.

This is not the first time BP has polluted either, although the magnitude this time is great.  Newsweek magazine reports that in 2006 the EPA and the Justice Department launched a criminal investigation into

two massive BP il leaks in Alaska caused by corroded pipelines.  One of the leaks spewed 2000,000 gallons onto the tundra. EPA investigators pushed to charge company officials with a crime.  Even though there were witnesses to how BP investigators had ignored repeated warnings about corrosion.

When the U.S. Attorney's Office in Alaska subpoenaed documents, BP set up a speical server with scanned copies of 62 million pages of documents.  With only three or four people on the case, the work was insurmountable; a few month s later federal prosecutors in Alaka were told to close the case.

Now, thousands of fisherman have no way to support themselves, presently.  Restauranteurs are equally worried. as the shrimp and oyster industries may be destroyed.  The American government has apparently forgotten too soon the devastation of the Exxon Valdez disaster and other tremendously damaging occurrences to the ocean in place of money dealings.
