Human activities that have indirect effects on animals can be just as harmful. When we build farms or factories, we destroy animal habitats and leave many animals with nowhere to live, or no food to eat. We can also put animals in danger without ever entering their habitats. Air, water, noise and light pollution can all have a deep and damaging influence quite far from their source. Partly due to pollution caused by ship traffic and other human activities, the dolphin population has dropped greatly. As the human population continues to grow, so does the effect we have on animals.
