On Tuesday next week, environmentalists will be celebrating the 55th annual Earth Day since its inception in 1970. As usual, climate change, and its evil twin — “renewable” energy that is actually the dirtiest source of power on the planet — is a primary focus of this year’s Earthday.org. This distracts activists from addressing real environmental concerns, such as overfishing in the oceans and pollution of air, land, and water in the developing world.
