Vehicle Fuel
As the world continues developing, there has been a rise in the use of vehicles as well. There are millions of vehicles running on our roads and releasing toxic fumes of sulfates and nitrates every day. When released into the air, they come in contact with the water vapor present in the air, and become mild corrosive acids such as hydrochloric or sulfuric acid. They then return to the ground as acid rain. The acid percolates through the ground and mixes with the groundwater, which is then used by humans for consumption.
