Due to the high friction with the atmospheric gases, the debris burns up, causing the release of its chemical components, which may contribute to atmospheric pollution and ozone depletion. [12] Additionally, space debris orbits the Earth at extremely high ...

This became an important part of the Deep Green ideology. Throughout the rest of the history of environmentalism there has been debate and argument ...
