Leaves can regulate the climate and purify the environment. Can you give an example to illustrate this point?

First of all, it can regulate CO2 and O2. The intensity of different tree species is different, and the ability of broad-leaved species to absorb CO2 is stronger than that of coniferous species.

The second is the secretion of fungicides, such as Cryptomeria fortunei and Magnolia grandiflora. Osmanthus fragrans is weak.

Third, absorb toxic gases, such as honeysuckle and willow. Will absorb SO2, and silver willows will absorb CL2.

The fourth is dust retention, the crown is large and dense, and those with hairy or rough leaves have strong dust retention ability.

The above four points are the first aspect in improving environment, air quality, temperature, humidity and noise reduction.

In environmental protection, there are water conservation, soil and water conservation, other protection functions, and of course, the last one, as well as landscaping functions, which make people directly feel its intuitive beauty.
