First of all, the most intuitive thing is garbage, such as lunch boxes and tableware.
The second is the pollution in the cooking process, which is not as environmentally friendly as frying, smoking and barbecue.
Third, it is the pollution in the process of food collection. For example, animal husbandry has a greater impact on the environment than planting, and restaurants with a high proportion of vegetarian food are naturally more environmentally friendly than restaurants with whole meat.
Fourth, agricultural pollution, such as pesticides and fertilizers, agricultural machinery tail gas, clinker film and other industrial products.
Fifth, it is the pollution of food industry, such as water pollution caused by additive production and industrial pollution caused by food finishing.
If we want to talk about an environmentally friendly diet, we should first give priority to pure natural, organic and pesticide-free vegetables and fruits, supplemented by the meat of small animals. It is best to go directly from the agricultural front line to the dining table without food industry processing. Secondly, we should pay attention to cooking and eat it raw under the condition of ensuring cleanliness. This is the most environmentally friendly way to eat. If you want to cook, consider cooking first.
