What are the disadvantages and benefits of snow to people?

First, the newly fallen snow is loose and porous, which can store a lot of air and has the function of preventing freezing and keeping warm.

Secondly, the content of heavy water in snowmelt water is 25% less than that in ordinary water. Heavy water is a radioactive substance, which has a strong inhibitory effect on the life activities of various organisms. The low content of heavy water in snow is obviously beneficial to promote biological growth and development.

Third, the physical and chemical properties of snow water are different from ordinary water. Due to freezing, the gas in snow water is removed, and the conductivity and density have changed. Studies show that snow water is very close to the water in biological cells in physiological properties, so it shows strong biological activity. The ability of plants to absorb snow water is two to six times that of tap water. Snow water can stimulate the activity of enzymes and promote metabolism after entering organisms.

Fourthly, snow water contains more nitrides, which is five times that of rain water and higher than ordinary water. It can be said that it is a kind of fat water. "Falling red is not heartless, but turning into spring mud is more protective of flowers." In this way, snow moistens the land, nurtures crops and benefits mankind with its own "life".

Disadvantages:

1, blocking roads, affecting traffic and easily causing traffic accidents.

2, snow pressure plants, easy to make plants injured or killed.

3. Heavy snow can crush houses, causing casualties or livestock deaths.

4. Heavy snow can freeze some animals to death, or cover grasslands to starve all kinds of herbivores. Cattle and sheep die every year in Inner Mongolia.

Chun Xue is a devastating disaster for crops such as wheat and rape.
