• The coal fuel should be replaced with gas fuel to control the air pollution • The automobiles must be designed with emission control system • The wastes must be removed and recycled in the industrial plants and refineries • Plants like pinus and ribes need to be planted to metabolize the nitrogen oxides and other pollutants • Timely servicing of the car helps to keep it in a good condition, and also minimizes fuel exhaustion • Using public transportation helps to prevent the air pollution • Using alternative energy sources like solar energy, hydroelectric energy, and wind energy
2.Water pollution: When some foreign particle, organic, inorganic or biological impurities are added to the water so that it becomes unfit for use is known as water pollution.

• Avoid using salt to de-ice walk ways
• Maintain your septic system

• Limit the use of fertilizers and pesticides
• Awareness about biological control methods and their implementation • The grazing must be controlled and forest management should be done properly • The afforestation and reforestation must take place

• Proper preventive methods like shields should be used in areas of wind erosion and wind breaks • Remember to carry paper bags and minimize using plastic...
