Still few problems with this.
- intensive fish farming can lead to environmental issues, such as water pollution from fish waste, excessive use of antibiotics and chemicals, and the depletion of wild fish stocks used for fish feed
- some farmed fish species require a substantial amount of wild-caught fish to produce a relatively small amount of farmed fish
- the conversion of natural habitats like mangroves and wetlands into fish farms can lead to habitat destruction and loss of critical ecosystems that support various species
- in densely packed fish farms, diseases spread rapidly among fish populations, leading to mass mortality events. The use of antibiotics to control diseases can also contribute to antibiotic resistance, posing risks to human health
- introducing non-native or genetically modified fish into local ecosystems can disrupt the balance of the ecosystem and lead to unintended consequences
We have to switch to plant based diets.
It seems to me that nothing else will stop the environmental destruction, in this case overfishing, which alone threatens us with empty oceans in 2040's.
And it would solve the problem with warming oceans too.
Rapid phase-out of fossil fuels, together with a switch to a plant-based diet, would free up a land area the size of Africa. When reforested, this area would store so much carbon that we'd be able to store our entire 1.5C carbon budget in those forests and initiate a new "little ice age."
