I found this on Youtube about a week ago, and thought I would share it with you. It gives me a lot of food for thought. One thing in particular that interested me was the use of fossil fuels to maintain and harvest certain types of farming.
Vegetarians/Vegans have long argued that a plant diet is not only nutritionally sound but environmentally sound. This documentary highlights that this is not necessarily so. Although currently the majority of animal farms currently use a lot of fossil fuels to maintain the animals and fields, small time animal farmers can, with time and research maintain their livestock during winter without the use of heavy machinery and therefore fossil fuels. Rebecca Hosking says "our hay harvest by far is our biggest single use of machinery and fuel on this farm". She finds a small time farm who have researched and maintain their cattle throughout the winter months without resorting to hay to feed them. Their only piece of machinery is a quad bike. Vegetarian and vegan diets are heavily reliant on grain and energy to harvest these foods are heavy on the use of fossil fuels.
Watch and learn. It is in five parts and can be followed via links in youtube
