This article on Science Alert discusses the carbon impact of bottom trawling. It turns out that bottom trawling releases more carbon that has been stored in the the marine soil than the world's aviation industry: 1.47 billion tonnes of CO2. That's up to 20 percent of the atmospheric CO2 absorbed by the ocean each year and is "comparable to estimates of carbon loss in terrestrial soils caused by farming." As we try to reduce carbon emissions to limit global warming, we simply cannot afford to allow this to continue. That is in addition to the other terrible environmental impacts of bottom trawling, which destroys coral reefs (the nurseries and food sources for marine life) and other seabed ecosystems. Bottom trawling is like harvesting terrestrial farm crops by removing the topsoil; it is complete madness, and is patently not managing the oceans as renewable resources. Bottom trawling needs to be outlawed now, before it is too late. | |
