Which of the following is not a pollution control measure?

The option that is not a pollution control measure is "Channelling sewage into streams". This is because sewage contains various pollutants such as pathogens, organic matter, and nutrients that can harm aquatic life and human health. Therefore, channelling sewage into streams will worsen the pollution and harm the ecosystem. Pollution control measures aim to reduce or prevent the release of pollutants into the environment to minimize their harmful effects. Penalizing those who dump refuse on water or land, controlling emissions of smoke from automobiles and industries, ensuring no spillage of oil, and establishing government agencies like Federal Environmental Protection Agency (FEPA) are all pollution control measures.
