According to new estimates, farmed shrimp from Asia may have one of the highest carbon footprints of any food.
More than half of all shrimp farms are located in Asia, primarily in areas that used to be mangrove forests. Mangroves are trees that grow in salt water, and they are important for marine ecosystems because they provide nutrients and shelter for many fish, turtle, and wading bird species. Mangrove forests are also important because they serve as a carbon sink, removing and storing more than 1,000 pounds of CO2) per acre each year.
But around the world, mangrove forests are being cut down to build shrimp farms. These farms are also often short-lived. The intensive farming methods pollute the environment, and disease spreads easily among the shrimp, which means that shrimp farmers must frequently clear new areas to stay in business.
This is the fifth in a series of posts about how to green your life, step by step. Instead of burning out on fossil fuels, Will advises taking it easy on yourself and the planet.
Like the final chapter of Mindy Pennybacker’s book Do One Green Thing, my final entry of this blog series is about transportation, which is responsible for 28 percent of U.S. greenhouse gas emissions. This is by far the hardest area to tackle when going green. Technology and demand are helping to drive energy alternatives, but at the moment, for an average Joe like myself, it is tough to replace oil.
For an individual, breaking the addiction to fossil fuels can be overwhelming if you try to do it all at once. However, as I have learned from Do One Green Thing, change is possible, but easiest—and most sustainable— in moderation.
Here are some simple steps:
*Did you know that not driving one day a week can reduce your carbon dioxide emissions by about 400 pounds a year?
