What contribution do plants make to human beings?

1. Plants absorb carbon dioxide and make oxygen.

2. Absorb some harmful gases in the air, absorb dust and purify the air.

3. Developed root system ensures that soil and water will not be lost.

4. Adjust global temperature to make it more stable.

Step 5 provide food. Maintain the integrity of the food chain and species diversity.

6. Provide textiles, such as cotton-padded jacket.

7. Treat diseases. Protect human health.

8. Provide wood.

9. Provide fuel.

10, providing entertainment and satisfying human sensory needs (audio-visual, olfactory, etc. ).

Extended data:

Most solid substances in plants are obtained from the atmosphere. Through a process called photosynthesis, plants use the energy in sunlight to convert carbon dioxide in the atmosphere into simple sugar. These sugars are used as building materials and constitute the main structural components of plants. Plants mainly rely on soil as support and obtain water, nitrogen, phosphorus and other important basic nutrients.

Most plants need oxygen in the atmosphere (for breathing) and oxygen around their roots to grow successfully. However, some special vascular plants, such as mangroves, can make their roots grow in an anoxic environment.
