Sustainable Seafood

In an effort to meet growing demands for seafood,  Malaysian, Nicaraguan and Tanzanian fishers have resorted to a technique called “fish bombing” to maximize yields. Using bombs made from fertilizer and diesel fuel, the fishing technique destroys reefs and aquatic life. Researchers in Malaysia are now using acoustic sensors, previously used to locate urban gunfire, which can isolate the sound of an underwater explosion and allow police to identify and track down illegal fish bombing.

Ecosystems + Biodiversity

A hippopotamus generates around three quarters of a ton of dung each year. The combined dung of 4,000 hippos in Kenya’s Mara river has such a heavy impact that it’s actually affecting distant ecosystems. In the dry season, decomposing waste sucks oxygen from the water where hippos congregate and, when this polluted water washes downstream during floods, it can cause mass die-offs in fish and other wildlife.

A devastating string of North Atlantic right whale deaths in the Gulf of St. Lawrence has spurred the Canadian to new management measures for snow crab and lobster fisheries. Targeting the southern portion of the Gulf, these new measures (unveiled April, 2018) are designed to reduce accidental whale entanglements.  Via Canadian Geographic

Plastics

On Wednesday May 16th, the City of Vancouver approved Zero Waste 2040, a strategic plan that includes the banning of foam cups and takeout containers in restaurants, among other restrictions. “It’s a coastal city, with the plastic items having a significant impact on the environment,” said Albert Shamess, City of Vancouver’s director of waste management. “We feel it’s important to take action.” Via The Huffington Post

Renewable Energy

Massachusetts and Rhode Island have announced offshore wind projects that will deliver enough megawatts of energy to power 600,000 homes. The plan hopes to generate clean, reliable and cost-effective energy for future generations by significantly reducing greenhouse gas emissions that contribute to climate change.
