The direction and magnitude of the effects of ocean acidification, warming and deoxygenation on the ocean has been quantified by meta-analyses, [136] [142] [143] and has been further tested by mesocosm studies. The mesocosm studies simulated the interaction of these stressors and found a catastrophic effect on the marine food web, namely, that ...
Deforestation in the city of Rio de Janeiro in Brazil's Rio de Janeiro state, 2009. Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use.
Ocean acidification may also have an effect of 'gender discrimination' as spawning female corals are significantly more susceptible to the negative effects of ocean acidification than spawning male coral [73] Bamboo coral is a deep water coral which produces growth rings similar to trees. The growth rings illustrate growth rate changes as deep ...

Ocean acidification can impact marine ecosystems that provide food and livelihoods for many people. About one billion people are wholly or partially dependent on the fishing, tourism, and coastal management services provided by coral reefs. Ongoing acidification of the oceans may therefore threaten food chains linked with the oceans. [39] [40]
Other effect of deforestation in the Amazon rainforest is seen through the greater amount of carbon dioxide emission. The Amazon rainforest absorbs one-fourth of the carbon dioxide emissions on Earth, however, the amount of CO 2 absorbed today decreases by 30% than it was in the 1990s due to deforestation. [35]
One indicator (14.1.1b) under Goal 14 specifically relates to reducing impacts from marine plastic pollution. [ 3 ] According to the 2020 report on progress towards the Sustainable Development Goals, "current efforts to protect key marine environments and small-scale fishers and invest in ocean science are not yet meeting the urgent need to ...
Shrimp aquaculture projects are one of the biggest threats. The shrimp business is growing very fast because of high demand and high profits. One of the negative impacts of shrimp farms is that mangroves are being destroyed where the farms are built. [8] Mangroves however are very important for people living close to the coast.
