Can you imagine the Grand Canyon with barely any water flowing through it? A new report from conservation groups, the Glen Canyon Institute, the Utah Rivers Council, and the Great Basin Water Network, says that, as the Southwest becomes more arid, levels at Lake Powell on the Colorado River could be too low for water to pass through outlets in Glen Canyon Dam—something that could happen if there are two more dry winters.
"Rewilding" is a practice that returns land to natural conditions, and according to research from the UK Centre for Ecology & Hydrology (UKCEH), when used near farms, it can boost biodiversity without reducing crop yields. Over a ten-year period, researchers studied a 2,500-acre farm in southern England where several wildlife habitats were created from land that had been unprofitable or difficult to farm. The habitats had flowers for pollinators, seeds for birds, and grasses that supported small mammals and insects. The farm itself encouraged natural pest control.
Our appetite for electronics like smart phones and computers is generating a growing amount of waste when we toss outdated or broken devices. Some of this so-called e-waste can be recycled or repurposed but much of it ends up in landfills where toxic compounds leach into groundwater and soils.
Does it ever feel like there’s not enough time in the day? Well, technically, on June 29, there wasn’t. Earth's rotation was 1.59 milliseconds shy of 24 hours—the shortest day since scientists started keeping track with atomic clocks back in the 1960s, according to the National Physical Laboratory in England. And it wasn’t a fluke. July 26 was 1.5 milliseconds shorter than the total 86,400 seconds that make up a solar day. And it seems to be a trend. The site TimeandDate.com reported that, in 2020, Earth had 28 days that were less than 24 hours.
