Its not simply an attempt to create a new food source. It is removing the necessity for livestock (which are supposedly a contributing to factor to greenhouse emissions).
We (as a world population) continue to try to band-aid small cuts, while we have gaping wounds that remain untouched.
Cargo ships and oil tankers are the largest producers of pollution.

I don't know about the rest of the world, but here in the US a lot of what we consume is manufactured in China, and how does it get here? Cargo ships.
Furthermore, we pretend like we care about the planet, but we still buy from China, and China doesn't give 2 fucks about being green.
One of the biggest industrial countries in the world, and the one doing the least to curb it pollution/impact on the planet.
Many people believe that the Chinese wear these mask because their are concerned about the health impact the pollution is having, which also isn't true, the majority wear them because the pollution is so bad it will actually turn their skin yellow.
