Many laptops have a webcam built in to the computer screen, but external webcams are also sold.

Environmental Protection Agency: The US government agency founded to protect human health and to safeguard the natural environment--air, water, and land--upon which life depends.. The Environmental Protection Agency is known as the EPA.
The applicator is responsible for knowing and complying with the federal laws and regulations and the specific requirements in each state they may be working in. The United States Congress established the Environmental Protection Agency (EPA) in 1970 and has mandated that the agency regulate pesticides. The U.S. Department of Agriculture (USDA) regulated pesticides before EPA was created.
