Although the artificial neural networks used in the research are much less complex than the human visual system, this simplicity helped the researchers to identify and further understand what they believe is a fundamental principle behind why we see illusion: the statistics of our past visual experiences.

Extending that principle, perhaps with special bridges that can support local vegetation and thus allow animals the illusion of an uninterrupted habitat, might be a cheap way of letting man and nature rub along a bit better.
