Buying food

The current global system of producing and transporting food uses huge amounts of energy, is highly polluting to land, destroys biodiversity, and exploits growers and producers. Food consumption is one of the greatest areas of impact people have on the planet. If you can't grow your own, then choose locally grown, seasonal, and if possible organic or fair trade produce, and don't eat meat more than three times a week. But arguments continue as to whether it is environmentally better to buy imported organic tomatoes or those grown locally in artificial heat, and whether vegan-ism is preferable to limited meat consumption.
