Grassland is like the lungs of a city. It can absorb a lot of carbon dioxide, release oxygen and stop flying dust. It can also absorb various harmful gases, thus playing the role of filtering and purifying the air. The secretion of grassland has certain bactericidal effect, especially in eliminating urban noise.
According to measurement, most of the noisy noise disappears when it reaches the dense grassland. Grassland is of great benefit to human health, and green can reduce intraocular pressure. Clear and transparent air can improve the adaptability of eyes to light, so vision can be quickly restored and improved unconsciously. Therefore, the correct answer to this question is: absorb carbon dioxide to produce oxygen.
Grassland plays an important role in absorbing carbon dioxide and producing oxygen in environmental protection. Grassland is mainly planted with herbs and shrubs, which is suitable for the development of animal husbandry production. It has a unique ecosystem and is a renewable natural resource. The grassland area in the world accounts for about half of the total land area, which is the most basic means of production and base for developing grassland animal husbandry.
Grassland is a compound plant community, which consists of grass, flowering plants and light-loving plants. The ratio of flowering plants to light-loving plants has changed. Lawn has been kept in a low state for a long time, while grass with rich species can only be pruned once or twice a year, and grass with few species can be pruned many times a year, sometimes as many as six times.
Measures to protect the environment:
1, reduce waste, enough is enough, and waste too much needs to be solved after production is stopped.
2, reduce pollution, such as littering, garbage classification discarded to the designated trash can is conducive to the classification and recycling of sanitation workers.
3. Preventing uncivilized behavior, protecting the environment and wasting resources is also a way to protect the environment.
4. For non-profit organizations, it is often similar to turning off the lights for one hour around the world. If everyone doesn't respond to the activity, the activity will become meaningless. Through activities, more people can participate in environmental protection actions.
5. Start from yourself, do your own behavior well and then influence others, so that this awareness can be deeply rooted in people's hearts and environmental protection can be guaranteed.
