By 2030, it expects demand for seafood to be 30 percent higher than 2010 levels. Plus, the tens of thousands of edible creatures in the oceans offer a broader palette of flavors and textures to imitate compared with land mammals or fowl. Plant-based seafoods are spawning in the freezers and aisles of mainstream stores.
Oceanacidification, global warming, pollution: the causes of these threats are many and particularly difficult to address, insofar as they are extremely diffuse, and result from our entire development paradigm. Between 2010 and 2019, the amount of algae has increased by 20 per cent, corresponding with declines in hard coral cover.
According to a 2010 study on managing soils to mitigate climate change, soils used for agriculture contain 25 to 75 percent less soil organic carbon “than their counterparts in undisturbed or natural ecosystems.” .
To achieve this the IPCC calculates that annual global emissions of CO2 must be reduced to 45 per cent below their 2010 level by 2030, which was roughly 1.9 To limit global warming to a peak of 1.5C, which the impacts we are experiencing at 1.35°C gigatons of CO2 annually (GtCO2/year). Nature is no longer on our side.
While reefs are suffering because of a variety of factors — overfishing, pollution, and oceanacidification among them — it’s widespread warming that is causing the most concern, as sea surface temperatures have slowly ticked up over the last 100 years. A second followed in 2010. degrees Celsius.

Solar geoengineering, for example, does nothing to ameliorate oceanacidification, which occurs when the ocean absorbs carbon dioxide from the atmosphere. The potential effects of solar radiation management are so large and wide-ranging as to implicate almost every aspect of life on the planet.
The Chugach Regional Resources Commission, an organization made up of seven Indigenous governments in south-central Alaska, is leading several projects aimed at helping coastal communities adapt to the changing ocean. Climate pressures like oceanacidification have made it harder for the mollusks to build and maintain shells.
For years (and we mean many years), the ocean helped us mitigate the early effects of human emissions by absorbing greenhouse gases, like carbon dioxide and heat, from the atmosphere. As a result, more than 90 percent of the warming that happened on Earth between 1971 and 2010 occurred in the ocean.
