Pollution can be defined as the physical degradation or contamination of the environment through an emission of harmful, poisonous and toxic chemical substances.

Also, EPA research solutions, policy development, and enforcement of regulations through the resource Conservation and Recovery Act.

In some states, repair shops such as automechanic shops can accept used oil from do-it-yourselfers or Homeowners. Thus, this action would help to mitigate, reduce or prevent the pollution of the environment (society) by individuals fixing their engine oil-related problems themselves.
