Pesticides Float from distant farms to Protected Forests

According to a new study published in the journal of Environmental Science and Technology, large concentrations of pesticides have been found in higher elevations of mountain ranges. The discovery of these contaminations in areas thought they could never be reached might explain why there have been an unusually high number of frog species becoming endangered and extinct in Costa Rica's protected forests. The researching team took samples from 23 different areas around the country and found unusually high concentrations of the more than 9000 tons of pesticides that are imported into Costa Rica every year.
