News broke last week that we passed a grim milestone. There is now more CO2 in the atmosphere than at any time in at least four million years. The amount of carbon reached nearly 421 parts per million because of power plants, transportation, farming practices—and a less talked about source—buildings.
Scientists might have discovered the largest living organism on Earth—and it’s ancient—perhaps 4,500 years old. A team from the University of Western Australia and Flinders University discovered a single seagrass plant in Shark Bay off Western Australia that extends for about 110 miles—the same distance from Los Angeles to San Diego.
Home improvement stores have shelves full of chemicals that kill dandelions, which many consider to be unsightly blemishes on green lawns. But if not sprayed with chemicals, many people eat the plant in salads as all parts of the dandelion are healthy. They contain antioxidants, can reduce inflammation, and manage blood pressure.
Food waste is a huge problem worldwide. Not only do people go hungry, but discarded items took a lot of land, water, and energy to produce, only to have them rot in landfills and emit greenhouse gases that harm the climate.
