I bet greenhouse manufacturers don’t like their product being associated with global warming:
Greenhouse Gases, Greenhouse Emissions, Greenhouse Effect.
Describing global warming using the greenhouse analogy is pretty easy to understand, but probably a lot of people subconsciously believe greenhouses are bad or at least look on them suspiciously.
In the summer, they are definitely bad to work in.
At 19 a friend and I removed the old plastic coverings from 10 large greenhouses. That was hot work: we sweated like crazy working inside them.
I guess we could have removed the plastic from the outside, but we were 19 and not so smart.
They should put air-conditioners in those things!
note: If you are in a greenhouse during an earthquake, you don’t have to worry about being buried alive in the rubble. And if you are buried alive, people will be able to spot you quickly.
