About the only fish I'll eat now is canned wild-caught salmon at ~$2.70 (?) per 12 oz can....this even at a discount grocery. The can likely has BPA in the lining. Tuna is mostly polluted with mercury....the least expensive light tuna is from thailand...my dog won't eat it. The better tuna has more mercury. Even the salmon has some chemicals. Chinese farm raised fish is a no-no.
Bought some breaded fish when I got stupid...found that by thickness it was 2/3s breading...or basically fish flavored breading.
More people...fewer fish.....

The ocean is getting more acidic.
The pH has already dropped from ~8.2 to ~8.1 and plankton levels are about 40% lower now than in the 1950's. The acidity varies depending on the composition of the nearby coast - largely granite land like New England and the pacific northwest have more acidic ocean water than areas that are largely limestone, like the mid-Atlantic coast. As luck would have it, colder water means better fishing, and these areas most often have granite nearby. Also, colder water can absorb more carbon dioxide.
So, this is bad for the base of the ocean food chain - which is bad for the whole ocean. |
