One step that humans could take to decrease acid rain is to drive fewer cars. What evidence from the passage supports this conclusion?
“Nature depends on balance, and although some rain is naturally acidic, with a pH level of around 5.0, human activities have made it worse.”
“These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.”
“In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.”
“Over time, these neutralizing materials can be washed away by acid rain. Damage to crops, trees, lakes, rivers, and animals can result.”
