How is it, living in the Anthropocene?
Sea levels will likely rise a few feet by the year 2100. Current fish wet biomass is about 2 billion tons, so removing them won’t make a dent either. (Marine fish biomass dropped by 80% over the last century, which—taking into consideration the growth rate of the world’s shipping fleet—leads to an odd conclusion: Sometime in the last few years, we reached a point where there are, by weight, more ships in the ocean than fish.)
The current world shipping fleet has a displacement of about 2.15 billion tons (most of which is oil and ore), so yeah, we humans are now bulking out more volume in the oceans than the fish do (we’ve got a long ways to go before we overtake invertebrates and bacteria, I suspect).
The other depressing point in the article is that global warming is adding more water to the oceans every second, and that every 16 hours we’re adding more than that 2 billion tons of water to the ocean.
