Last week, diplomats from around the world met at the United Nations attempting to reach an agreement on how to protect our planet’s ocean in a fifth round of talks. The waters at stake are the high seas that begin 200 nautical miles off the coast of each country. Currently, only about one percent are protected from things like plastic pollution, abandoned fishing gear, overfishing, and the effects of climate change.
If you had to guess, which do you think could produce more lettuce—a rural farm or an urban garden? That’s exactly what researchers at the University of Lancaster in the UK set out to learn, and it turns out that urban farming produced up to four times more per square meter of some crops than conventional agriculture, including leafy greens, cucumbers, and tubers.
Wind farms are spreading around the globe, which is huge toward getting us to a clean energy future. But the wind turbine blades themselves have only about a 20-year lifespan and also new larger and more efficient blades at sea are coming online that can generate more electricity. That means lots of old blades are ending up in landfills—not a good look for a green industry—but what are you supposed to do with a piece of fiberglass the length of half a football field that’s not easy to transport or recycle?
Ever since the “Age of Sail” between the 16th and 19th centuries when global trade was dominated by galleons and clipper ships, vessels have operated from the same maxim: SFTW—“Sail Fast, Then Wait.” To this day, ships book it to their destinations without any regard for local conditions, only to idle offshore until a berth becomes available, wasting fuel and generating toxic emissions.
