From Edutopia, this is the story of a high school student who brought his hobby — growing food with an aquaponic system for his family and neighbors — to his school’s underutilized greenhouse, creating a local edible schoolyard for his fellow students and his community. And he’s not stopping there:
"I want to bring this system into many different schools. You know, learning opportunity that a system like this provides is immense. You’ve got water chemistry, agriculture, science, physics, mathematics, economics. A lot of these subjects could be modeled from this particular system. If I can provide a curriculum to go with this system then the knowledge of aquaponics will be proliferated throughout, hopefully, the United States."
Polar Bears Eat Goose Eggs in the Arctic’s summer months, but now scientists are studying how melting sea ice might affect the bears’ eating habits in the years to come. Will more eggs be on their menu? Utah State University Ph.D candidate David Iles narrates this remote camera footage from Western Hudson Bay near Churchill, Manitoba, as we watch polar bears find these high-calorie snacks (and a few of the birds that laid them):
“In terms of snow geese there’s 50,000 pairs out there, and that could be quite a substantial benefit to polar bears that do happen to take advantage of them,” he continued. “But what we don’t yet know is how often that overlap happens, what types of bears are taking advantage, and what it could mean for both polar bears and waterfowl.”
Melting down and recycling existing steel products is a more efficient and sustainable process than mining iron ore to make virgin steel. From the EPA:
Recovering steel not only saves money, but also dramatically reduces energy consumption, compared to making steel from virgin materials. In turn, this reduces the amount of greenhouse gases released in to the air during processing and manufacturing steel from virgin ore.
“There’s a lot of other pollinators out there,” explains Gratton. The 500 or 600 wild bee species that live in Wisconsin are only a fraction of the 4,000 native to the United States. But because they tend to be solitary, aren’t easily managed, and don’t produce honey, they’ve mostly flown under the radar.
