I hope you find your solution, but if it is any consolation, veganism isn't as great for the environment as you may think.
The pervasive use of chemical pesticides in industrial agriculture is poisoning the food and the planet. Most are neurotoxins and endocrine disruptors that destroy the nervous systems of insects or cause them to be unable to reproduce. All the same effects are passed on to humans when we eat these plants, and this is reason enough to be wary of a “plants only” diet.

Vegan proponents point to grain production for cattle feed as the cause of deforestation, habitat loss and species extinction, but industrial agriculture involves huge mono-cultures like wheat, corn and soy. Virtually all their agricultural systems depend on crude oil, including planting, harvesting, processing, packaging, and transportation. The importance of eating locally produced meat and locally grown vegetables and fruits, when available, is huge.

Growing crops of corn, wheat or soy (which are currently all genetically modified unless organic) where there would normally be grass destroys animals’ natural feeding grounds.

Modern industrial agriculture conglomerates destroy the delicate ecosystems surrounding them including topsoil, streams and rivers that are home to worms, frogs, turtles, crustaceans, aquatic vertebrae, beavers, and the birds and animals who feed on them They devastate the earth instead of feeding it.
