Main Body
Ocean acidification means lowering of the pH of ocean. Ecosystem due to dissolution of CO2. (from B) at lower end (ocean fertilization)
IMPACT → (a) Stress on organisms coral bleaching, loss in kelp forest, sea grass,
(b) erosion of rocks may lead to release of dissolved carbon and methane hydrate into atmospheric.
(C) Worsen the food webreakdown web of marine ecology. e.g.: loss of appetite, offspring trauma
Ocean warming is the increase in average temperature of world oceans due to 'climate change' and greenhouse gas (GHG) effect from anyone at 2yC (IPCC 6th assessment)
IMPACT → (1) Coral U bleached explosion of zooxanthale (Irrelastic)
Oxygen loss is the reduction in dissolved oxygen in the marine water body.
IMPACT → (1) killing of marine animals (CHI backed)
