What are the major sources of air pollution?
The major sources of air pollution include burning fossil fuels (such as coal, oil, and gas), industrial processes, vehicle emissions, and agricultural activities.
How does air pollution affect human health?
Air pollution can cause a range of health issues, including respiratory problems (like asthma and bronchitis), cardiovascular diseases, and even cancer. Long-term exposure to air pollution can shorten life expectancy and reduce overall quality of life.
What are the consequences of land pollution on soil quality?
Land pollution can degrade soil quality by introducing harmful chemicals, toxins, and waste materials into the soil. This can lead to reduced fertility, loss of nutrients, and contamination of groundwater, affecting plant growth and agricultural productivity.
How does land pollution affect plants and animals?
Land pollution can harm plants and animals by disrupting their habitats, contaminating their food and water sources, and exposing them to toxic substances. This can lead to reduced biodiversity, ecosystem imbalance, and even extinction of certain species.
