We started discussing marine
harvesting and fishing today by talking about who harvests the most
seafood (China), who eats the most seafood (China), and which people eat
the most seafood pounds per person (the Maldives). Americans are about
sixth on the list as far as consumption, but we are the number one
consumer and importer of shrimp. Importing shrimp is damaging to the environment for two reasons.
1.
Shrimp that are farmed in other countries are not as regulated as here
in the states, so shrimp farm pollution is not as regulated and it
damages coral reefs. Also many mangroves are cleared to build these
farms.
2. US boats are required to have turtle excluder devices (TED) on
trawl nets so that turtles do not get caught in shrimp nets and drown.
Other countries do not regulate this and as a result catch and drown sea
turtles.
To make a environmentally responsible seafood
choices, choose shrimp that are farmed or caught in the US. For more
sustainable seafood choices, check out Seafood Watch.
