example of tragedy of high seas starting w high population
high population -> higher demand for fish -> overfishing ->affects food chain -> fish stocks collapse
example of tragedy of atmosphere starting w more cars
-> pollution -> enhances green house effect -> global warming -> affects antarctica eg. peninsula warming
example of tragedy of antarctica starting w burning fossil fuels
-> enhances gg effect -> global warming -> decreases albedo effect -> more heat absorbed by water -> affects penguin colonies and fish
example of tragedy of outerspace starting w more countries putting more satelittes in space
-> overcrowds space -> more space debris -> spacecraft cannot safely leave earth
