Many people are realizing the problem of plastic pollution and other marine debris though, and have taken steps to mitigate it. For example, from 2000 to 2006, NOAA and partners removed over 500 tons of marine debris from the reefs in the Northwestern Hawaiian Islands. [22] Cigarette butts also damage aquatic life.
As a result, climate change is expected to lead to changes in the economy, environment and population of the Caribbean. [ 35 ] [ 36 ] [ 37 ] Temperature rise of 2°C above preindustrial levels can increase the likelihood of extreme hurricane rainfall by four to five times in the Bahamas and three times in Cuba and the Dominican Republic .

By 2100, sea level in the Caribbean is expected to rise by 1.4 m. [23] Rise in sea level could impact coastal communities of the Caribbean if they are less than 3 metres (10 ft) above the sea. In Latin America and the Caribbean, it is expected that 29–32 million people may be affected by the sea level rise because they live below this threshold.
Between 1993 and 2018, the mean sea level has risen across most of the world ocean (blue colors). [71] Coastal ecosystems are facing further changes because of rising sea levels. Some ecosystems can move inland with the high-water mark, but others are prevented from migrating due to natural or artificial barriers.
The Bahamas is expected to be highly affected by sea level rise because at least 80% of the total land is below 10 meters elevation. [19] [20] As a small island developing state, the Bahamas is vulnerable to escalating disease outbreaks, and climate change could affect the seasonality of outbreaks and transmission of disease. [21]
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
Any U.S. citizen who needs assistance while in the Bahamas can contact the U.S. Embassy in Nassau. The embassy can be reached by phone at 242-322-1181 or by email at ACSnassau@state.gov . You can ...
The sea animal's aquatic ecosystem may also collapse due to the destruction of the food chain. Additionally, ghost fishing is a major threat due to capture fisheries. [16] Ghost fishing occurs when a net, such as a gill net or trawl, is lost or discarded at sea and drifts within the oceans, and can still act to capture marine organisms. [16]
