Brand new experiments that are incredibly old

A British geologist has volunteered to spend 48 hours in an airtight chamber relying on the oxygen produced by plants to survive.

“This experiment has never been done before with a human – it seems a fascinating challenge to see if plants really could keep a person alive,” Stewart said.

So I’m left wondering how this “scientist” missed the experiment called “The Earth” and how our oxygen rich atmosphere is a result of photosynthesis from plants and algae? What I only learnt today is that there is strong evidence to suggest that chloroplasts probably originated as symbiotic cyanobacteria¬†in a similar fashion to mitochondria
