oh well where do you come from?What good is it to want to quantify precisely all of this?
well to estimate the importance right? when you say billions of fish, it is an estimate! but where do you come from?
IN fish farming there is a direct link between the rate of dissolved oxygen in the water, the temperature of the water and the production of fish. when it is hot there is less oxygen and therefore less fish, which is why we add oxygen to the water to increase production.
So if the oceans heat up and the fish have no more oxygen, it is the animals that need less that proliferate. Less fish less fishing.
so it's not too hard to quantify the number of fish less in relation to co2 in the atmosphere. After no one has yet quantified the value of the fish stock in the oceans, so quantified the loss on the stock ???
