Final answer:
Plants contribute to society through bioremediation, intercropping, and vector control.
Step-by-step explanation:
Plants contribute to society in various ways, beyond what is typically covered in biology courses. One original way is through bioremediation, where plants are used to remove or neutralize pollutants from a contaminated environment. For example, certain plants can absorb heavy metals from soil, helping to clean up industrial sites.
Another way is through intercropping, which involves planting different crops together in the same field. This practice improves soil health, reduces pests and diseases, and increases overall crop productivity.
Lastly, vector control is another important contribution of plants to society. Certain plants are natural insect repellents and can help control the spread of vector-borne diseases, such as malaria and dengue fever.
