2 min Science: Trees pollute. Is that bad?
Ronald Reagan blamed trees for polluting. Should we cut them down? As usual, the effect depends on context.
This video was inspired by a conversation with a visitor to Biosphere 2, who asked “Wait, so trees emit all these hydrocarbons to the air, is that good or bad?” Traditional environmentalism says a thing is either good or bad. Holistic management of the planet should be based on the complexities understood through science.
