Where is most life on Earth?

A poorly-worded, vague question. What does "most life" even mean? Biomass, numbers of individuals, number of species, most birds? For example, there are more described species in rainforest than in the oceans.

we do our best to kill as many sea creatures though ! Plastic and pollution as well as over fishing.

i love 💕 the sea

Obviously because water is the most part of the world

Humans mostly use only the tops of oceans.
