Children and Our Future
Children and Environmental Health Hazards
As we consider environmental problems, we must not forget the world’s children, who are at special risk for environmental health problems precisely because they are children. Their bodies and brains grow rapidly, and they breathe in more air per pound of body weight than adults do. They also absorb substances, including toxic substances from their gastrointestinal tract faster than adults do.
These and other physiological differences all put children at greater risk than adults for harm from environmental health hazards. Children’s behavior also puts them at greater risk. For example, no adult of normal intelligence would eat paint chips found on the floor, but a young child can easily do so. Children also play on lawns, playgrounds, and other areas in which pesticides are often used, and this type of activity again gives them greater exposure. Young children also put their hands in their mouths regularly, and any toxins on their hands are thereby ingested.
Poverty compounds all these problems. Poor children are more likely to live in houses with lead paint, in neighborhoods with higher levels of air pollution, and in neighborhoods near to hazardous waste sites. Poor children of color are especially at risk for these environmental problems.
Three of the greatest environmental health hazards for children are lead, pesticides, and air pollution. Lead can cause brain and nervous system damage, hearing problems, and delayed growth among other effects; pesticides can cause various problems in the immune, neurological, and respiratory systems; and air pollution can cause asthma and respiratory illnesses. All these health problems can have lifelong consequences.
Unfortunately, certain environmentally induced health problems for children are becoming more common. For example, US children’s asthma cases have increased by more than 40 percent since 1980, and more than four hundred American children now have asthma. Two types of childhood cancer thought to stem at least partly from environmental hazards have also increased during the past two decades: acute lymphocytic by 10 percent and brain tumors by 30 percent.
It should be evident from this overview that environmental health hazards pose a serious danger for children in the United States and the rest of the world. Because children are our future, this danger underscores the need to do everything possible to improve the environment.
