How can overfishing lead to ecosystem collapse

Ecosystems are an integrated process that requires each part to be present to allow the whole system to operate correctly. This is similar to a car engine that requires all of its parts to work - "over removing" the crankshaft affects the whole engine.In the case of fish they are both consumers and consumed. Fish eat smaller plants and animals that would overpopulate their niche in the ecology if not removed. This ould cause a depletion of the smaller plants and animals they feed on crating a barren base ecology. As fish are consumed, the animals they feed would be starved for food and either die out or move to other locations. They might also switch to less nutritious food or to species that are not as numerous and deplete their numbers.

It doesn't stop there. Bears, as an example, eat salmon. They then wander through the woods where their faces provide nutrients for trees. The trees provide ecologies for a wide range of animals and have other functions like soil building with their leaves or needles and soil stabilization with their roots. Therefor - no salmon, no bears, no healthy trees, no birds and squirrels, no control of erosion, eroded soil fills the streams and the hydrogeology of the ecosystem changes.

What advantage does nuclear power have over fossil fuels

The major advantage is that the fuel, once introduced, lasts a considerable time without replenishment, and so does not require a constant transported supply.

Other advantages are offset by disadvantages : it produces almost no CO2, but it does give off substantial waste heat. It produces little waste, but the waste produced is highly dangerous and difficult to dispose of.
