Halting overfishing and the plastic pollution of the oceans could help tackle the climate emergency by improving the degraded state of the world’s biggest carbon sink, a report has found. The oceans absorb both the excess heat generated by our greenhouse gas emissions, and absorb carbon dioxide itself, helping to reduce the impacts of climate chaos. But we are rapidly reaching the limits of the oceans’ absorptive capacity as our pillage of marine life is disrupting vital ecosystems and the natural carbon cycle.
Creating ocean sanctuaries and forging a new treaty to protect the oceans, with a target of safeguarding at least 30% of the oceans by 2030, could restore many areas to health and combat global heating, according to the report entitled Hot Water: the climate crisis and the urgent need for ocean protection, published by Greenpeace International on Wednesday.
“The ocean’s biology is one of our best allies in the fight against climate change,” said Louisa Casson, oceans campaigner at Greenpeace UK. “But over-exploitation and our addiction to fossil fuels have pushed our ocean to the brink of collapse. Ocean protection is climate action – if we can save our ocean, it can save us.”
