Human activities that have i    1     effects on animals can be just as harmful. When we build farms or factories, we destroy animal habitats and leave many animals with n    2     to live, or no food to eat. We can also put animals in d    3     without entering their habitats. Air, water, noise and light pollution can all have a deep and damaging influence quite f    4     from their source.
