Kind of like how fertilizer runoff is a good thing since it causes algae blooms, and more life is good right? Except that it disrupts existing ecosystems and can cause vast oxygen-free dead zones.
One of the things we should be doing is intentionally fertilizing oceans, particularly the "deserts" where not much grows at all, as an intentional way to cause blooms and sink carbon.
Yes, let's not stop doing the thing that we know is destroying our ecosystem, and instead, lets try a mass geoengineering effort when we are incapable of knowing what unintended side effects will happen when we do it on a large scale.
