    but people seem to ignore the process of acquiring oil. Oil drilling is a dangerous and risky process. It runs the risk of contaminating the surrounding water and harming the organisms that live in it. The process also emits large amounts of carbon dioxide into the atmosphere. The Deepwater Horizon Oil Spill‚ better known as the BP oil spill‚ was a prime example of how oil drilling is an extremely harmful process. An explosion on the rig caused it to spill 60‚000 barrels of oil per day into the Gulf
