Nuclear pollution is the most dangerous type of pollution. Answer: On a worldwide basis the number of deaths and illnesses from pollution can be significant. Some sources indicate that up to 40% of all deaths ae related at least partly to pollution. Gases causing global climate change are the most significant as they are likely to caue wordwide problems over the next hundred years.
The principle immediate problem would be contamination of drinking water by fecal pollution from sewage and diseases passed on by poor sanitary waste disposal.
Air pollution from industrial sources such as particulate, sulfur dioxides, volatile organics and toxins would probably be second.
Industrial pollutants such as benzene, Mercury, lead,asbestos, arsenic, seelenium etc would be low but measurable
Pollution from radioactive sources such as radon (from granite and drywall), smoke detectors, denatured uranium would be considerably lower than deaths from secondhand smoke. a damage from power plants, X-rays etc would be even lower.
I think the pollutants that do most damage are carbon oxides, freons, and heavy metals.
pollution causes harm by hurting animals and the environment around us (this it coming from A fifth grader)
pulling on the nerve
Most pollution in streams is caused by agricultural runoff. Many farms and ranches do not take precautions against the runoff.
loss of habitat
It causes brain damage
Cardiac arrest is the most common condition that causes cerebral hypoxia. When the heart stops pumping, oxygen-rich blood cannot be delivered to vital organs such as the brain. Hypoxia to the brain causes irreversible brain damage after two minutes.
Air pollution
land pollution causes soil damage .This would affect the farmers.
Air pollution is one of many major forms of pollution. It causes major damage to the environment including acid rain.
A hurricane causes the most damage overall.
cars
Pollution
gasoline

i believe it is carbon monoxide from cars
The explosive blast behind the shockwave causes the most damage.
The mass of the wavefront causes most of the damage.
