Concerned scientists — World Scientists’ Warning to Humanity: Second Notice
It’s been 25 years since more than 1,700 scientists, including a majority of the world’s living Nobel laureates in the sciences, co-signed the Scientists’ Warning to Humanity. This startling document published by the Union of Concerned Scientists, expressed concern about ozone depletion, freshwater availability, marine fishery collapses, ocean dead zones, forest loss, biodiversity destruction, climate change, and continued human population growth.
