Who gets to starve then, so you can eat your organic chicken etc...?
There are too many people on the planet for everyone to eat that way & without intensive farming methods not enough food to around because you don't get the same yields.
Or do we rip out all the rain forests etc... for land, because most of the land used for animal farming is not suitable for crop growing, so you can't just pull out those cows & plant a field of crops instead.
So, who gets to starve & who gets to live on a subsistence diet so you can feel better about what you eat?
It's a great theory, but in practice a lot of people will need to die for a vegan or all organic diet for the privileged few.
Nobody chooses to eat poor welfare meat, but if that is all they can afford, then they will choose to eat it rather than nothing.
How about you pay double for everything you buy, for your hairdresser, cleaner, match the cost to the NHS of every treatment you have so everyone else can live the organic lifestyle you prefer.
Or do you want everything else to stay the same but the rest of the world to struggle for something only the wealthy get to have a choice about?
