Arctic sea ice has reached a record low wintertime maximum extent for the second consecutive year. Scientists from the National Snow and Ice Data Center and NASA reported this finding, noting the extent reached 5.607 million square miles on March 24. This represents the lowest maximum extent recorded in the satellite era.

On March 7, 2017, Arctic sea ice reached a record low winter maximum, according to NASA and the National Snow and Ice Data Center (NSIDC). This followed a warm winter. Globally, combined Arctic and Antarctic sea ice levels hit their lowest point since satellite measurements began in 1979, specifically on February 13.

Marine scientist Dr. Daniel Pauly explains that aquaculture sustainability varies greatly. Low-trophic species like bivalves (mussels, oysters) and seaweed are sustainable. In contrast, industrial farming of carnivorous fish, such as salmon, depends on wild fish feed. With China producing over two-thirds of global farmed fish, expanding these predator species significantly magnifies environmental impact.

To support sustainable seafood, ocean health, and marine conservation, advocate for low-trophic aquaculture. Demand stronger regulation of open-net pens and real industry transparency. Share this video to help spread the message.

Most purchases become waste within a year, an economic reality Tom Szaky terms "negative demand." He asserts this is fixable, as everything is recoverable if economics support the effort. Though convenience led us to abandon reuse, modern systems globally prove large-scale reuse is achievable across many product categories.

Szaky, founder and CEO of TerraCycle, pioneered recycling for challenging items like cigarette butts and diapers. He also launched Loop, a platform for products in durable, reusable packaging from major brands. An author recognized by global organizations, his insights were shared at a TEDx event.
