The main objective of pollution control in environmental engineering is to reduce harmful emissions and waste. This focus is essential for protecting human health, preserving the environment, and ensuring the sustainability of natural resources. Pollution can have severe impacts on air and water quality, soil health, and biodiversity. By implementing measures to control pollutants, engineers aim to minimize the release of toxic substances and contaminants into the environment.

Pollution control includes a variety of strategies such as designing systems for waste treatment, improving energy efficiency, and developing technologies to minimize emissions from industrial processes. These efforts contribute to a cleaner, safer environment and help promote public health standards.

In contrast, the other options do not address the primary concerns of pollution control. Limiting natural resource extraction is more concerned with sustainability than directly controlling pollution. Enhancing agricultural production can sometimes lead to increased pollution if not managed correctly, particularly through the use of fertilizers and pesticides. Promoting industrial growth often focuses on economic development, which may conflict with pollution control efforts unless it's paired with sustainable practices. Thus, the correct focus on reducing harmful emissions and waste addresses the critical need for a healthier ecosystem and society.
