Which in turn are also relatively small compared to the damages of cattle and fishing.
Seriously adapting our diets around being more sustainable. I'm not advocating for veganism or such, but at least to understand that eating a burger pollutes as much as driving a large vehicle for 50 miles and that maybe we can substitute that with poultry or eggs or cheese many times.
What about putting trees down for soya fields?
Speaking of deforestation:
> Globally, 77% of soya is produced for animal feed, 19.2% for direct human consumption and 3.8% for industry (biodiesel, lubricants, etc.).
https://www.deforestationimportee.ecologie.gouv.fr/en/affect...
Poultry protein efficiency is 21% and beef 3%
> We find that reallocating the agricultural land used for beef feed to poultry feed production can meet the caloric and protein demands of ≈120 and ≈140 million additional people consuming the mean American diet, respectively, roughly 40% of current US population.

Edit:
Note the soy usage vary around regions. The first link is from a French gov page, after the previous citation it gives the world repartition:
> In animal feed, the largest consumer of soybeans is chicken (37% of world production), followed by pork (20.2%), aquaculture products (5.6%), dairy products (1.4%) and beef (0.5%).
Which is quite different than the French reparation :
> flesh and egg poultry account for 44% of total [imported] soy, then diary/mixed cows (36%) then flesh cow (8%) and pigs (6%)

Soy protein are 97.9% as digestible as beef
> protein qualify can be scored in terms of its Protein Digestibility-Corrected Amino Acid Score (PDCAAS). Soy achieves a PDCAAS of 0.92, comparable to beef at 0.94.

The DIAAS is sensibly worse (soy 0.898 - beef 1.116) but still far from the beef protein efficiency cited above (3%)
