Now, with about 4 million miles of public roads crisscrossing the United States, automobiles and roads have had a very adverse impact on America's animal population. Roads result in habitat loss and habitat fragmentation. These animals also run the risk of being killed on or along the roads and highways. Hitting a deer will kill the deer but will also result in major car damage. In Washington State, there are also special fish ladders to help specific endangered fish populations to migrate safely.
American people use dietary supplements.
The dietary supplement industry is part of the American economy, and annual sales are about 4 billion dollars. This law does not require the herbal industry to study these herbal products unless the product is to be marketed as a drug. Since dietary supplements are not drugs and not under the drug laws, the manufactures don't have to test them as drugs. Once marketed, the burden of proof is on the FDA to prove a dietary supplement is unsafe before it can be removed from the shelves. Substances approved for NTP study undergo a series of assays to determine acute, subchronic, and chronic effects.
