Human activities22 that have indirect effects on23 animals can be just as harmful24. When we build farms or factories, we destroy7 animal habitats8 and leave many animals with nowhere to live25, 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 influence26 quite far from their source. Partly due to27 pollution caused by28 ship traffic and other human activities, the dolphin9 population has dropped greatly29. As the human population continues to grow, so does the effect we have on animals30.
