Acid rain Acid rain Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulphur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Some governments have made efforts since the 1970s to reduce the release of sulphur dioxide and nitrogen oxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes, and sulphur dioxide
Driving in the United States affect a cause of traffic congestion and heavy traffic at the investigated roads. As a result, it causes an increase in CO2 emissions of up to 18%. Using Eco-Driving under limited speed and control of acceleration and deceleration can possibly affect CO2 emissions. Several pollutants can be made by car-driving such as carbon dioxide, carbon monoxide, sulfur oxides, nitrogen oxides, hydrocarbon, and lead. They pollute the environment and affect human health. Carbon dioxide is the dominant greenhouse gas that is one of the causes of global warming. It includes flooding, droughts, storms, and disruption of the ecosystem. Carbon monoxide implores
