The test is due tonight ugh it's for environmental science not bio

The tragedy of commons, is when somebody acts individually, and not in the way a group of people wants. You could say it's when they act out of common sense in a way, and the only thing that represents that is the first option.

Not everybody likes the idea of pumping and other gasses in to the atmosphere, in fact, nobody should. But there are some people that benefit from that (owners, managers from factories and their associates).

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
