Depens on how you pose the question. Ships can move far more goods per horsepower than a truck, so they should pollute less. OTOH ships usually burn much cruder (dirtier) oil, so smoke puff by smoke puff they pollute more.
Fossil fuels are primarily transported through pipelines, trucks, trains, and ships. Pipelines are the most common method due to their efficiency, while trucks and trains are used for shorter distances or where pipelines are not available. Ships transport fossil fuels internationally through oceans and waterways.
A substance that pollutes the air, water, or soil is called a pollutant. Pollutants can come from various sources such as industrial activities, vehicle emissions, and agricultural run-off.
Iron ore is commonly transported using trains, trucks, and ships. Trains are often used for long-distance transportation from mining sites to processing plants or ports. Trucks are typically used for shorter distances within mining sites or between processing facilities. Ships are used for bulk transportation of iron ore across large bodies of water to reach international markets.
Several sources contribute to air pollution, including industries, vehicles, power plants, agricultural activities, and household activities like burning fuel for heating and cooking. Pollutants released by these sources include nitrogen oxides, sulfur dioxide, particulate matter, and volatile organic compounds, which can have harmful effects on human health and the environment.
Overall, cars and trucks contribute more to pollution than factories do. This is because there are far more vehicles on the road emitting pollutants on a daily basis compared to the emissions from individual factories. Additionally, vehicles release a variety of pollutants directly into the atmosphere, including greenhouse gases and particulate matter, which can have a significant impact on air quality and public health.
the car that pollutes more is the three wheeler and the BMW X5
