Why have sustainability?
Glass half empty answer…
The graph below shows that around 1970 humans reached the biocapacity of the earth. Biocapacity is the earth’s ability to provide the resources we consume. The graph shows that humanity currently needs about 1.5 earths to sustain our current consumption. This might seem impossible – how can we consume more than the earth can provide? The answer is that we are making up the shortfall by using up the earth’s natural capital like freshwater, soil, biodiversity, coral reefs and wetlands. These crucial resources will run out unless we change.

It is all too easy (and depressing) to be negative – the problems are dire and the solutions seem complex and difficult.
However, there are many, many direct and indirect benefits to being sustainable and by focusing on these we will find out that the solutions aren’t so difficult, the problems will disappear and we will all be better off.
By implementing the means for sustainability such as: doing no harm; reducing consumption; buying fresh local food; being self-sufficient in energy using solar income; being precautious and preventative, and; being efficient; we will be rewarded with:
- Better health
- Stronger, plentiful relationships
