Ethiopian cuisine
Both Ethiopian Orthodox Christians and Muslims avoid eating pork or shellfish, for religious reasons. Pork is considered to be unclean in both Ethiopian Orthodox Christianity and Islam. Many Ethiopians would abstain from eating certain meats, and would mostly eat vegetarian and vegan foods.
Gowanus Canal
Attempts have been made to reintroduce oysters and other shellfish to the canal, because they can filter out toxins and help clean the water. One oyster can process as much as of water a day. The NY/NJ Baykeeper environmental group gives oysters to volunteers who then monitor their health and growth in local waterways. They have helped Katie Mosher-Smith and The Gowanus Community Oyster Garden's Stewards to partner with teachers, students and the Gowanus Dredgers Canoe Club to install and monitor oyster cages in the canal. In 2012, landscape architect Kate Orff proposed a design for a park with a living reef containing oysters, mussels, and eelgrass. As part of a pilot program, ropes were hung off of a pier to attract ribbed mussels.
