A Coastal Environment Untouched by People
The natural environment continually renews itself, thereby staying in balance.
Some natural degeneration of the environment occurs, but it is offset by its natural ability to regenerate itself.
When the degeneration rate and the regeneration rate are equal, then the environment is kept in a consistently healthy state.
It is constantly changing, but stable. This is called 'dynamic equilibrium'.
However, if something happens to affect this balance, then over time the environment can degrade beyond its ability to repair itself.
Your turn to experiment!
In the graph below, the environmental quality is initially constant, at 100%. That's because the regeneration rate the and the degeneration rate are the same, at 5%.
Try increasing the degeneration rate, and see what happens to the environmental quality!
If the degeneration rate remains high, the environmental quality drops dramatically over the years.
