Benefits:
1. Wind can spread plant pollen and seeds, helping plants to pollinate and reproduce. For example, the most common example is that dandelion seeds are spread by wind.
2. Wind energy is a widely distributed and inexhaustible energy source. By using wind energy to generate electricity, we reduce the use of fossil energy and protect the environment.
3. Wind plays an important role in improving farmland environment in agriculture. We know that air flows to form wind, which transports and exchanges carbon dioxide, oxygen, heat, etc. in the air. Create conditions for the growth of crops.
Disadvantages
1. The impact of strong wind on the land. Strong winds may cause soil erosion and land desertification. For example, the formation of the Loess Plateau.
2. Strong winds can cause mechanical scratches on leaves, lodging of crops, broken trees, and falling flowers and fruits, thus affecting yields.
3. It can spread pathogens, spread plant diseases, cause crops to fall, break trees, drop flowers and fruits, etc., causing harm to people's production and life.
Precautions in windy weather
Be careful not to use the narrow passages between high-rise buildings when walking or cycling. Because the long and narrow passage will form a "narrow tube effect", the wind force will increase in the passage, which will bring certain dangers to pedestrians.
Some billboards may collapse due to weak installation due to strong winds; some old trees are dead and have weak foundations, and may break in strong winds, causing serious damage to pedestrians. Danger.
Bad things:
1. Spread pathogens and spread plant diseases. High-altitude winds are the meteorological conditions for pests such as armyworms, rice planthoppers, rice leaf rollers, and migratory locusts to migrate over long distances.
2. Strong winds can cause mechanical scratches on leaves, lodging of crops, broken trees, and falling flowers and fruits, thus affecting yields.
3. Strong winds also cause soil erosion, sand dune movement, and damage farmland. Blind reclamation in arid areas will cause land desertification due to wind. Strong winds and snowstorms in pastoral areas can disperse livestock herds and aggravate freezing damage.
4. Winds sometimes cause a small number of casualties and missing persons, but also mainly damage houses, vehicles, ships, trees, crops, communication facilities, and power facilities.

Extended information:
Wind in nature
Wind refers to the horizontal flow of air. Wind direction refers to the direction of the wind; wind speed refers to the speed of air flow. Meteorological services often use wind power levels to express wind speed. Wind promotes the exchange of dry, cold and warm and moist air and is often an important cause of weather changes.
Wind is a natural energy source. A long time ago, humans learned to make windmills and use wind power to blow them to pump water and process food. People also used windmills to generate electricity. The movement of a sailboat is also driven by the wind. Wind plays many roles in daily life, but it also often brings disasters to humans. Storms, typhoons, hurricanes, tornadoes, etc. are very harmful to humans.
