Supreme Court Guts Clean Water Act as Conservative Justices Side with Polluters and Developers

We look at how a new Supreme Court ruling awards a major victory to polluters and land developers. In a 5-4 decision last week, the justices sharply limited the authority of the Environmental Protection Agency to protect and preserve wetlands under the Clean Water Act. The ruling ends protections for about half of all the wetlands in the contiguous United States, jeopardizing access to safe drinking water for millions. “That just defies science, physics, commonsense,” says Earthjustice’s Sam Sankar, who urges Congress to take action to once again protect the country’s critical water resources.

Inside The Grand Canyon

This guerrilla style documentary film captures a Colorado River rafting expedition through the Grand Canyon. Exhilarating and sometimes dangerous expeditions like this are not often considered when discussing global climate change but could be helpful to enlighten more folks about the changes to our planet. This rafting trip will soon be a thing of the past with record draughts continuing due to ongoing global climate change caused largely by humans. This is just a tiny slice of natures many warning signs of things to come. We find ourselves in a world of ongoing disbelief and hesitation in lieu of planning for the clear and present dangers from climate change. The Colorado River has already reached devastating levels for communities that depend on the water and electrical power resource. Government study in 2022 showed that Lake Powell could reach ""dead pool"" by 2023. There is no plan to mitigate the catastrophe that will leave over a million and a half people with no electricity.
