How does mercury get into fish

Climate change doesn't just change the weather!

"So climate change doesn't just mean that the weather changes," says study director and Harvard scientist Amina Schartup in an article dated August 7, 2019, published in The Atlantic appeared (2). “Climate change also means that what ends up on our plates will change.” In the case of fish, it means: more mercury, more poison, more disease.

And if you think you are on the safe side with fish from aquaculture, you will actually receive fish that is most likely less contaminated with mercury, but has plenty of antibiotic residues. Because when animals that would normally live in the vastness of the ocean are now crammed together in a very small space, diseases and thus antibiotics are the order of the day.
