Fish stocks are collapsing globally too, and continuing to consume food that has a large ecological footprint will threaten our future food supply.
As many as 40% (63 billion pounds) of fish caught globally every year are thrown out, and some scientists say we could see fish-less oceans by 2048. Moreover, the waste runoff from animal agriculture leads to ocean dead zones — massive algal blooms so oxygen deprived that no animal life can survive.
