What is an example of pollution mitigation that reduces environmental impact before it occurs?

Green buildings represent an example of pollution mitigation that proactively reduces environmental impact before it occurs. These buildings are designed and constructed with a focus on sustainability and energy efficiency, minimizing waste and promoting the use of renewable resources.

In green building practices, materials are chosen for their low environmental impact, and design features such as energy-efficient systems, natural lighting, and water conservation are prioritized. By implementing these features, green buildings not only reduce the carbon footprint during their construction and operation but also limit pollution associated with energy production and waste generation.

Other options, such as landfills or industrial waste treatment, address pollution after it has occurred. Landfills manage waste but do not prevent pollution from happening in the first place. Industrial waste treatment involves processing pollutants after they are generated, which is reactive rather than preventive. Similarly, controlled burning may be used to manage waste or clear land but can produce pollutants if not managed properly, again addressing pollution post-factum. Therefore, the proactive nature of green buildings makes them a clear example of pollution mitigation by reducing environmental impact before it occurs.
