Do plants cause harm to humans?

No, humans only bring harm to plants.

Yes, some plants are like overbearing people, and they will take up space for other creatures, such as water hyacinth.

Plants are inseparable from human survival and living relationships.

1. Plants are the main food for humans. Humans need a large number of plants to serve as food, including food provided by crops; edible oils provided by cash crops; Fruit trees and fruits provided by economic plants and much more.

2. Plants provide important raw material resources for human life. Cotton and linen plants provide textile raw materials for human wear; Timber provides building materials for human settlements, building houses, building bridges, etc.

3. Plants provide a large amount of feed for livestock and animal products needed by human beings, and the main energy supply of animals lies in plants, and animals will die because of lack of energy without plants.

Fourth, plants form a forest scale and are the purifiers of the air. Forest plants grow 15-50% less sulphur dioxide in the air than in open land. In the summer of high temperature and humidity, the absorption rate of sulfur dioxide by forest plants will increase with the vigorous physiological activity of forest trees.

The relative humidity is above 85%, and the rate of absorption of sulfur dioxide by forest plants is 5-10 times faster than that of 15% relative humidity. Humans need to breathe oxygen, while plants can absorb carbon dioxide and exhale it. The oxygen released by plant photosynthesis is supplied to humans.

5. Forest plants have a regulating effect on climate. The dense canopy of forest plants absorbs, scatters, and reflects some of the solar radiation energy in summer, reducing ground warming. Because the roots of the forest trees go deep into the ground, they continuously absorb the water in the deep soil for the transpiration of the trees, so that the forest normally forms fog and increases precipitation.

Without plants, soil erosion leads to greater water scarcity and less arable land. Plants also regulate the global environment.

6. Plants themselves have the function of conserving water, and the decay layer of dead branches and leaves on the surface of plants is increasing, forming a thick humus layer, which has the functions of strong water absorption, delaying runoff and weakening flood peaks. The canopy of the tree has a trapping effect on rainwater, which can reduce the impact of rainwater on the ground and maintain water and soil. The canopy can hold back 10-20% of precipitation, most of which evaporates into the atmosphere, and the rest falls to the ground or seeps into the soil along the trunk of trees to become groundwater.

7. Plants in complex ecosystems, as producers, support the existence of various biological chains. Plants are the main source of energy, an important part of the energy cycle, and the main body to maintain the balance of the ecosystem.

The emergence and development of human beings have always been accompanied by plants; People's perception of plants has undergone a process of constant change. Human beings rely on the minimum living conditions provided by plants, such as perching, feeding, laboring, etc., and plants will quickly be fatal to human survival once they are lacking, and no matter the survival or living environment, they all restrict the safety of human beings.

I don't think dripping Kannon will, it should.

Vegetation plays an important role in soil formation, so when destroyed, it can cause soil erosion. degrading soils, such as grasslands into deserts; The second is to bring environmental pollution problems, such as eutrophication of water bodies.

Plants can photosynthesize, convert inorganic matter into organic matter, and live independently as an autotrophic organism. Therefore, when it is destroyed, it will reduce the carbon sink effect. The amount of carbon dioxide in the air increases, which in turn contributes to global warming.

Resulting in the destruction of ecosystems. Vegetation plays an important role in the ecosystem and is a habitat for animals, insects, etc. Biodiversity is also destroyed when vegetation is destroyed.

Causes cosmetic problems. There is no vegetation, bare mountains or ruins, and it is clear that there is no affinity for nature's dusty rocks.

1. Human beings are at the top, without plants, animals and people cannot survive, and plants need animals and people to spread seeds, interlocking, a mistake will make the ecology unbalanced, causing a large-scale extinction, so we must protect animals and plants.

2. All the oxygen that humans rely on for survival is produced by plants.

3. Plants are the providers of the human food chain.

4. For a long time, plants were the main way for humans to obtain energy, including coal and 5 charcoal.

5. Humans are destroying and destroying the planet's biodiversity.

6. Plants are very adaptable, and if humans eventually destroy the ecology of the earth and humans themselves, plants will be the ultimate victors.
