Describe the concept of "venting" refrigerants.

Venting refers to the illegal and harmful practice of releasing refrigerants into the atmosphere. This is significant because refrigerants can contribute to environmental issues such as ozone depletion and climate change. The EPA has strict regulations against venting these substances, recognizing that many refrigerants are potent greenhouse gases.

In context, options discussing legal processes or recycling do not align with the definition of venting. Controlled recovery and recycling are methods to manage refrigerants responsibly, aiming to minimize environmental impact. Therefore, understanding venting as an illegal practice is crucial for compliance with environmental laws and for protecting the ecosystem from harmful substances.
