Resilience – the ability to respond to changes

Nature is exposed to changes all the time, but it is able to respond to such changes. In forests, for example, trees fall in storms and are cut down by people; however, because of nature's ability to respond to changes, trees grow in their place and eventually replenish the forests.
This does not, however, happen in all cases. We have learned that forests can undergo sudden change and be unable to return to their original state. That is, they have lost the ability to respond to change.

The ability to respond to changes is called resilience. Professor Walker has studied resilience in depth. As an ecologist he encountered resilience while considering sudden changes arising in natural ecosystems. Through his research, he came to see resilience as very important not only for ecosystems, but also human society.
