Along Jamaica's 894 km (556 mi) of coastline are 763 km 2 (295 sq mi) of coral reefs as of 2014. [7] However, the reefs were once much larger. About 85% of Jamaica's coral reefs were lost between 1980–2000. [8] Coral reef distribution on the northern coast of Jamaica extends from Morant Point in the east to Negril in the west.
In 2005, 34 percent of Jamaica's coral reefs were bleached due to rising sea temperatures. [128] Jamaica's coral reefs are also threatened by overfishing, pollution, natural disasters, and reef mining. [129] In 2009, researchers concluded that many of the corals are recovering very slowly. [130]
A 2020 study reports that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse gases are cut. Warming in mesopelagic and deeper layers could have major consequences for the deep ocean food web, since ocean species will need to move to stay at survival temperatures. [69] [70]
Killer whales play an important role in our ocean's ecosystem. Female orcas can live up to 90 years, and male orcas live up to 60 years. Whales can communicate through sounds ranging from clicks ...
In the case of orcas like Tahlequah, this includes addressing environmental issues such as water pollution, damming rivers, and overfishing. And she might be the best encouragement for advocacy yet.
Due to orcas' complex social bonds, many marine experts have concerns about how humane it is to keep them in captivity. [116] Resident orcas in the eastern North Pacific live in particularly complex and stable social groups. Unlike any other known mammal social structure, resident whales live with their mothers for their entire lives.
The warming of ocean waters has caused coral bleaching and the degradation of coral reefs, which are vital to marine biodiversity and fisheries. Coral reefs support a large proportion of the world's fish species, providing food and livelihoods for millions of people. As ocean temperatures rise, the symbiotic relationship between corals and ...
Graph showing historic temperature change globally and in the Caribbean region. Climate change in the Caribbean poses major risks to the islands in the Caribbean.The main environmental changes expected to affect the Caribbean are a rise in sea level, stronger hurricanes, longer dry seasons and shorter wet seasons.
