I chose this action item because I saw someone else post about it on the feed, and I was curious to learn more about how our seafood choices could impact the environment. I’ve always considered choosing fish over other types of meat to be better because it is usually the healthier option. However, reading about all of the ways that fishing can contribute to carbon emissions and destroy ecosystems has made me realize that I want to put more thought into the types of fish I am eating.
In terms of wild-caught fish, it is important to not overfish. Overfishing, depending on the where the species is in the food chain and the ability/speed in which it can procreate, can affect other populations of fish. For example, large fish like cod, snapper, and grouper live for a long time and do not reproduce quickly. Therefore, these species are very sensitive to overfishing. Other fish species in the middle of the food web could result in a lack of food for bigger fish and can reduce the algae consumption, which keeps coral reefs healthy. The website seafoodwatch.org even said “the percentage of fish stocks that are within biologically sustainable levels have decreased from 90 percent in 1974 to 65 percent in 2017.” I feel like even though it is only four years later, the number of fish stocks has reduced even further.
I highly recommend checking out the website seafoodwatch.com. It provides you will a lot of information about how current fishing methods are contributing to the climate crisis, but it also has a lot of information about how these practices could become more sustainable. It also has a place where you can search different types of fish and find out which types of fish have the lowest environmental impact depending on where it was caught, if it was farmed, etc. This will help me make more informed decisions about the fish I eat in the future. I also saved the website to the home screen of my phone, so I could check this website quickly whenever I am buying fish.
There was also an article about salmon that was listed as one of the sources on the drawdown ecochallenge. It reveals why salmon are more important to our ecosystem than we previously thought. Apparently, salmon do not just feed bears, orcas and humans, but they also feed the trees when they come back from the ocean to spawn and die. They deposit much needed nitrogen and phosphorus for the forests. Salmon can also move the landscape. When they have sed and bury their eggs into the riverbed, they loosen it and make it more likely to move when the river floods. The article references a study in which the lead author demonstrated that “the landscape surrounding the streams where salmon spawn would be nearly a third taller if the salmon weren’t there.” It is really fascinating to see how this one species of fish is able to have such a dramatic impact on aspects of the environment that transcend their watery homes.
