Which of the following groups of people would be the least affected by air pollution? a. people with asthma b. infants c. teenagers d. the elderly
Weegy: Which of the following groups of people would be the least affected by air pollution? The answer is a. people with asthma Most air pollution is unlikely to cause any serious health effects for the average person. [ If air pollution is severe, you can get eye irritation and/or have trouble breathing. People who smoke or suffer from respiratory problems (such as asthma, lung disease, bronchitis, ect.) are more sensitive. Of course, effects of air pollution will vary for the individual. While air pollution may or may not cause asthma, it is more likely to trigger an attack if you already have asthma (but not as much as an infection or allergen.) Source ; ] (More)

The best method to improve air quality is to _______. a. use technology to reduce the pollutants in air b. produce less pollution c. produce less pollution and use technology to reduce the pollutants in air d. better utilize land and technology to prevent pollution
Weegy: d. [ better utilize land and technology to prevent pollution There are many different kinds of pollutants, but some of the more larger problems result from: Greenhouse gases - Carbon dioxide and methane are two of the most important of these gases, [ called greenhouse gases because they trap heat in the earth's atmosphere. This is already causing severe problems around the world and the situation will only get worse. The rising temperatures will likely lead to more severe weather events, cause shifts in natural communities, and probably lead to greater species extinction rates, among numerous other effects. Heavy metals - Most heavy metals, such as mercury, are a natural part of the earth's crust, and would be slowly released into the environment over time anyway, just from weathering of soils and rocks. However, our consumption of fossil fuels has greatly increased the introduction of heavy metals into our environment. ] ] (More)
