in oceans on coral reefs is concerning because it takes many years (decades) to repair and regrow corals. Disease Disease is a serious threat to many coral species. The diseases of coral may consist of bacterial, viral, fungal, or parasitic infections. Due to stressors like climate change and pollution, coral can become more vulnerable to diseases. Some examples of coral disease are Vibrio, white syndrome, white band, rapid wasting disease, and many more. These diseases have different effects on the corals, ranging from damaging and killing individual corals to wiping out entire reefs. In the Caribbean, white band disease is one of the primary causes for the death of over eighty percent of Staghorn and Elkhorn coral (Reef Resilience). It is a disease that can destroy miles of coral reef fast. A disease such as white plague can spread over a coral colony by a half an inch a day. By the time the disease has fully taken over the colony, it leaves behind a dead skeleton. Dead standing coral structures are what most people see after disease has taken over a reef. Recently, the Florida Reef Tract in the United States has been plagued by a stony coral tissue loss disease. The disease was first identified in 2014 and as of 2018 has been reported in every part of the reef except the lower Florida Keys and the Dry Tortugas. The cause of the disease is unknown but is thought to be caused by bacteria and be transmitted through direct contact and water circulation. This disease event is unique due to its large geographic range, extended duration, rapid progression, high rates of mortality and the number of species affected. Recreational diving During the 20th century recreational scuba diving was considered to have generally low environmental impact, and was consequently one of the activities permitted in most marine protected areas. Since the 1970s diving has changed from an elite activity to a more accessible recreation, marketed to a very wide demographic. To some extent better equipment has been substituted for more rigorous training, and the reduction in perceived risk has shortened minimum training requirements by several training agencies. Training has concentrated on an acceptable risk to the diver, and paid less attention to the environment. The increase in the popularity of diving and in tourist access to sensitive ecological systems has led to the recognition that the activity can have
