Document Summary
2050 = 9. 2 billion (increase competition for earth resources: nas consume most energy, raw materials per person than any other (worldwide) Sulfur dioxide [yellowish-brown gas product of burning fossil fuel. Consequiences: heart and lung diseases, precursor of acid rain]. Particulates [tiny solid particles or liquid droplets suspended in the air; product of cigarette, combustion engine. Consequences: irritate lungs and carry heavy metals and cancer-causing agents]. Carbon monoxide [gas originates primarily from motor vehicle emissions; conseguences: interferes with blood"s ability to carry and absorb oxygen, impaired thinking, slows reflexes, drowsiness, unconsciousness, and death]. Nitrogen dioxide [amber-coloured gas emitted by coal-powered electrical utility boilers and motor vehicles; lungs diseases]. Ozone [a form of oxygen; irritates respiratory mucus membranes causing coughing and choking. Lead [metal pollutant, motor vehicles, birth defects, affects circulatory, reproductive and nervous systems]. Hydrocarbons [chemical pollutans in the air; combination of carbon and hydrogen, internal combustion engine, formation of smog]: photochemical smog: brownish-yellow haze (neblina) resulting from the combination of.
