Question

which human activity would be most likely to have a negative impact on the environment?
planting trees to control soil erosion
limiting the use of chemicals that kill weeds.
burning coal and oil to generate electric power.
stopping the draining of swamps.

Explanation:

• "Planting trees to control soil erosion" is an eco - friendly activity that helps the environment by preventing soil erosion and sequestering carbon.
• "Limiting the use of chemicals that kill weeds" reduces the amount of harmful chemicals in the environment, which is beneficial.
• "Burning coal and oil to generate electric power" releases large amounts of pollutants like greenhouse gases (e.g., carbon dioxide), sulfur dioxide, and nitrogen oxides into the atmosphere. These pollutants contribute to air pollution, climate change, and can have negative impacts on human health and ecosystems.
• "Stopping the draining of swamps" helps in preserving wetland ecosystems, which are important for biodiversity, water purification, and flood control.

Answer:

C. Burning coal and oil to generate electric power.
