53 percent of Earth’s fish stocks are fully exploited, but consumption of fish continues to increase. Our hauls of fish will be smaller and smaller as the years go by, and governments will continue limiting fishing in order to protect our ocean ecosystems. This scarcity of fish meat means that the price of fish will stay on its rising course, putting healthy fish protein out of reach for all but the richest of consumers. The pollution of the ocean also allows for heavy metals like mercury to accumulate in fish, limiting the recommended consumption amounts of this otherwise nutritious and healthy source of energy.
Fishing is killing our planet. Our ocean ecosystems can’t take the strain of increased fish production, and fish consumption is in a steady rise. Money is being poured into creating efficient aquaculture systems, to grow fish in tanks on land for human consumption. While this is a move in the right direction, if we’re going to make this system as efficient as possible we need to rethink things from the bottom up. Aquaculture is a system of inputs and outputs, why would we have our expensive food inputs create energy for the fish only to have that energy diverted into things we don’t need, like swimming or having a heartbeat? Why can’t we have a system that only puts energy into growing the parts that people want?
