Due to overfishing, pollution, global temperature increase, and change in pH to the world's oceans, the South China Sea is suffering from a lack in biodiversity among marine life. [30] Historically, China was the world's largest capture fisheries and aquaculture producer, making the fish market a significant part of the Chinese economy. [39]
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]
Overfishing (2006 Pilot Environmental Performance Index) Although there is a decline of fisheries due to climate change, a related cause for this decrease is due to over-fishing. [ 58 ] Over-fishing exacerbates the effects of climate change by creating conditions that make a fishing population more sensitive to environmental changes.
Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
A recent survey of global ocean health concluded that all parts of the ocean have been affected by human development and that 41 percent has been fouled with human polluted runoff, overfishing, and other abuses. [26] Pollution is not easy to fix, because pollution sources are so dispersed, and are built into the economic systems we depend on.
Governments and investors are pouring billions of dollars into emerging technologies to combat global warming in long-shot bets that entrepreneurship can help lead the way to a climate-friendly world.
Since the 2010s, the government has given greater attention to environmental protection through policy actions such as the signing of the Paris climate accord, the 13th Five-Year Plan and the 2015 Environmental Protection Law reform [6] From 2006 to 2017, sulphur dioxide levels in China were reduced by 70 percent, [7] and air pollution has ...
The United States and China have agreed to resume a working group on climate cooperation and pledged a major ramp-up of renewable energy, the two sides announced Wednesday ahead of a leaders ...
