List one other human activity that has led to positive and one other human activity that has led to negative impacts on the oceans?

positive: ecosystem organizations that go out and do things like pick up trash and save animals that were affected by trash.

negative: human waste being thrown into the ocean/not recycling to save the ocean

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
