We’re doing that regularly now.
There are always algues and fish unless we go out of our way and poison the ocean.
You mean like the Pacific garbage patch? Or the numerous “spills” and effluent pipes that feed directly into the ocean? I think we’ve already got that killing the oceans thing managed.
I thought so too but with the warming trends we are experiencing at unprecedented rates the planet does not have time to adapt as well. We are now looking at a possible Venus scenario if this warming continues at this rate. If we look closely we are still increasing our load on the planet and thus increasing the speed of the cycle. Meaning all flora would not have the thousands of years to adapt to the warming as it has previously in earth’s history.
We may just kill every live thing on the entire planet because of our greed.
