Factories emit sulfur dioxide into the air which forms acid rain when combined with moisture, harming both humans and animals. They also dump garbage and waste into bodies of water. Cutting down trees can cause soil erosion and floods. To help the environment, we should consider the harmful effects of industry, pollution, and deforestation.
