Talking about green diet

When you go shopping in the supermarket, have you noticed some packages (boxes) of milk powder, tea, coffee, preserved fruits, drinks, etc. They are all printed with the same pattern-two green leaves holding a green bud in the sun, which is the logo pattern of "green food". These foods are famous "green food".

You may wonder, isn't green food just those green vegetables and fruits? How come even milk powder and drinks have become green food? In fact, green food refers to safe, nutritious and pollution-free food. The logo pattern of green food tells us that green food comes from a pure and pollution-free environment and can bring us great vitality.

Why is green food popular? This should start with environmental pollution.

Environmental pollution is a major problem that puzzles all mankind and threatens the survival of mankind. Because most of the food in people's food structure comes from crops, poultry, fish and eggs in the field, if the growing environment of animals and plants is polluted, harmful substances will accumulate in their bodies, so that people who eat the food processed by these crops or livestock will be poisoned and affect people's health.

Industrial sewage is an important pollution source. For example, factories that make dyes, pesticides, light bulbs, batteries and switches usually contain mercury in their wastewater, which flows into rivers, making fish growing in rivers contain a lot of mercury.
