I can appreacite being vegetarian coz of religious or health purposes but I find it harder to fathom if the reason for being vegetarian is to save the earth.
IMO, moderation is key regardless whether u are vegetarian, canivore, omnivore or even cannibal especially it comes to saving the earth. No point ordering portions that can feed up to 10 persons when there are only 3 persons at the table. We will just end up with loads of wastage and at lot of resources are being churned up just to process our waste. Just walk around the restaurants and hawker centers or even people's dinner table at home and it's criminal how some of us waste food.
