4 Environmental Effects

1) Poor Parental Care

(Ex: Of a pregnant woman takes certain drugs, malnourished, contracts infections, smokes, drinks or is exposed to second hand smoking, her child is at risk of having learning disabilities and a lower IQ).

2) Malnutrition

(Ex: The average IQ gap between severely malnourished and well-nourished children can be as high as 20 points).

3) Exposure to Toxins

(Ex: Dust, contaminated soil, lead paint, old lead pipes can cause brain damage and damage to the nervous system).
