So someone on a forum told me this about veganism and the environment:
Him: "Animals take Oxygen and breathe out Carbon Dioxide which Humans can't use.
Plants take Carbon Dioxide and breathe out Oxygen which Humans can use.
By eating plants you are killing off our supply of Oxygen and causing an increased level of Carbon Dioxide production.
Vegans are destroying our planet"
Me: "Vegetarians use less resources like water, food, oil, contribute less CO2 to the atmosphere, and animals are not killed for their consumption.
Raising livestock contribute more to global warming than automobiles, and is the second leading cause of global warming behind industrial pollution.
Being a vegan for 1 year;
How many animals a vegan saves: 200~
How many lbs of meat a vegan didn't eat: 200~
Lbs of CO2 not released into the atmosphere: 1,609~
Also, we usually don't eat trees. Your claim is literally nonsense.."
Him: "How much oxygen is produced by a single leaf in an hour : 5mL == 120mL a day == 43.8L of oxygen a year from a single leaf. Humans requires about 50L of Oxygen an hour to survive. ( source =https://io9.gizmodo.com/5955071/how-many-plants-would-you-need-to-generate-oxygen-for-yourself-in-an-airlock ).
Every time you rip a leaf off a plant you're effectively making someone's life over the course of a year 1 hour shorter. How do you feel about this?"
Me: [Insert what I should say here
