Now, new studies reveal that some medicated baby powders have detectable levels of lead. The active ingredient in the medicated powders is zinc oxide, which is frequently contaminated with lead. Lead exposure is known to cause developmental delays in children until at least age five.
Studies now show that urbanization is disrupting photosynthesis and creating vast heat islands.
Satellite data indicate that cities like Atlanta can register heat 12 degrees above temperatures in the surrounding countryside. Thunderstorms and other weather disturbances are also being linked to urbanization. As the world's undeveloped countries strive to industrialize, the pollution they create not only affects their own environment, but also creates problems for other environments thousands of miles away. After use abroad, residues of these chemicals are blown thousands of miles by wind currents to faraway soil and water, including that of the United States. For each 10.6-ounce steak you eat, 35.2 pounds of livestock feces and urine are produced.
