Sometimes, as with thalidomide, if horrible defects are obvious at birth, these are factored into the equation. Even if this was enough, government cut-backs mean that almost all of the tests are being done or paid for by the manufacturers. The fact is, current standards are not properly protecting the environment or our health. Nor are we given the information we need to protect our-selves. Looks at the emerging scientific evidence linking many synthetic chemicals in our environment with a wide array of health, development and reproductive problems in humans and wildlife.
Human beings are vertebrates.
We have backbones. So do fish, reptiles, amphibians, birds and all other mammals. Hormones are like little tiny keys travelling around our bodies, seeking out the organ they are destined at a precise time to unlock. Hormone keys, for example, unlock menstruation and prompt the growth of underarm hair in humans. Another way to think of the hormone system is as the body's traffic lights.
