Animal research is an unscientific methodology for chemical assessment.
Each year, tens of millions of various types of chemical products are manufactured for commercial, industrial, agricultural, military, household, and personal use around the world. Although the exact number is unknown, it is estimated that as many as 70 million different types of toxic and hazardous products are used just by U.S. industries each year. It is these chemicals that contaminate our air, soil, streams, oceans, and underground water supplies, as well as our food and bodies. They do so while they are being manufactured, as they are used, and when they are disposed of. They pollute the air when chemicals escape into the atmosphere from factory stacks during the process of production, use, and disposal.
