Deforestation to plant veggie crops.
Pesticides that are ingested by consuming the veggies.
Toxins from pesticides and fertilizers entering the water supply.
Agricultural run off contributing to toxic algae blooms killing fish and sickening humans.
What else...???
Oh yeah, displacement of wildlife.
Fossil fuel powered farm equipment pollution.
Radiation from alien crop circles. 🤭
Consumption of large amounts of water for crops.
Carbon emissions from the plants manufacturing the farming equipment, the planting, harvesting, packaging (mostly plastics), and shipping of produce.
Migrants exploited to pick veggies that cannot be done mechanically.
Having to hear the constant self righteous virtue signaling from vegans.
Veggies are inhumanely harvested. We know that they scream (clicking noises) when injured by cutting, pruning, or plucking.
Okay... I'm starting to get silly. Still true, but silly.
