Burning any fuel can lead to some pollution the case of biofuels the pollution types may be:
it causes pollution
soil pollution. burning can cause air pollution and breathing cause respiratory problems. water pollution.
Of course, burning any solid fuel generates air pollution.
Biofuel, or biomass, is sometimes the burning of vegetation to produce energy. Burning, especially incomplete burning, can release smoke and other air borne particulates as pollution. The carbon dioxide released was only recently removed from the atmosphere (when the vegetation was growing) so it is not a pollution causing global warming. (This is why biomass and biofuel is counted as clean renewable energy.)
The trains themselves do not cause pollution, but the source of the power such as a coal burning power plant does.
Automobiles, burning of matter and using of natural resources at an exploiting level cause much pollution.
Water pollution is cause by: -the human activity: like when they thrown something away especially in to the water.... -the factory: cause when they flown the water waste in to the river, the sea.... Air pollution is cause by: -burning: forest burning, oil burning(running machine), transportation, factory and so on. so we can say air pollution cause from smoke.....
It pollutes the air
Yes, but since biofuel is a substitute for diesel its only used in diesel burning cars.
source:(http://en.wikipedia.org/wiki/Biofuel)we use biofuels because they do not make as much pollution as normal fuels.
Pollution can deteriorate our body very badly. Excessive pollution can cause burning of eyes also sometimes can cause suffocation. Breathing in of any pollutants is not good for the health. It can cause lungs to lose its efficiency.
Yes. For example, burning logs for energy or fires causes pollution (smoke and ash)
