The Precautionary Principle

The precautionary principle employs "guilty until proven innocent" methodology, and suggests that we should avoid using questionable chemicals and materials until we know they're safe.

When we decide to avoid the use of certain chemicals, materials, or building techniques because they may harm our health or cause serious environmental damage, we are employing the precautionary principle. This principle says that we should avoid potentially harmful actions even if we are not scientifically certain of the extent of the potential damage.
