In southern California people are getting sick.
Contamination is the leading cause of the illnesses reported.
Recently it has been strongly advised to have your Hepatitis A and B immunization shots if you are spending an ample amount of time in the ocean. Sewage, offshore oil drilling, and rain runoff are some of the main factors for the contamination. Along with those factors, littering and ignorance are making it more and more dangerous to spend time in the ocean.
