>Globally, land-use change is the direct driver with the largest relative impact on terrestrial and freshwater ecosystems, while direct exploitation of fish and seafood has the largest relative impact in the oceans (well established) (Figure SPM.2) {2.2.6.2}.

>Over one third of the world’s land surface and nearly three-quarters of available freshwater resources are devoted to crop or livestock production {2.1.11}. Crop production occurs on some 12 per cent of total ice-free land. Grazing occurs on about 25 per cent of total ice-free lands and approximately 70 per cent of drylands {2.1.11}. Approximately 25 per cent of the globe’s greenhouse gas emissions come from land clearing, crop production and fertilization, with animal-based food contributing 75 per cent of that.

Background on IPBES https://en.wikipedia.org/wiki/Intergovernmental_Science-Poli...:

>The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is an intergovernmental organization established to improve the interface between science and policy on issues of biodiversity and ecosystem services.[1] It is intended to serve a similar role to the Intergovernmental Panel on Climate Change.[2]

According to this [1], producing tofu for protein consumes more energy (fuels), and emits more greenhouse gases, than producing chicken. Tofu wins in total calories produced, but chicken wins if we only look at the amount of protein produced.

We don't know what fraction of plants can be used to produce these plant-based egg and shrimp, what what happens to the parts of the plants that they were not able to put into use in these products. We don't know if they are more or less efficient way to turn plants into protein, than poultry or dairy.

Vegans are vegans for many reasons, the environment is just one of them. Maybe Tofu is not as easy on the env as chicken, but on average a plant-based or completely vegan diet is way better than a meat/fish/milk/egg-based one.

Anecdote from Germany: Anti-Vegans or Meat-Conservatives always like to say "Yeah you vegans say your food is way better for the environment, but then you only eat avocados which need tons of water!!!" which is of course completely wrong (and the avocado water thing can be helped).

People didn't wait for ultra processed plant based food to be vegetarians/vegans. If anything it's just capitalism catching on a trend now that the market is big enough.

Nestlé doesn't give a single fuck about ethics and morality
