Put simply, sustainability means 'enough for everyone, forever'. It describes the ability for things to keep going at the same rate and in just as good condition as before. It is tempting for humans to think that we should be able to do anything we want. Unfortunately nature does not work like this – our planet has limits. Every living system can only take so much use before it starts to weaken and decline. When this decline reaches a tipping point the living system slows down and can never reclaim its former glory.
