Resource scarcity

Not only has the human population quadrupled in the last 100 years, but our personal consumption of resources has grown tenfold. In our lifetime, the average person uses 100,000 tonnes of fresh water, 750 tonnes of soil, 720 tonnes of metals, 5 billion energy units and emits 300 tonnes of greenhouse gas. Key resources are becoming scarce and landscapes worldwide are being ruined to obtain them.

The self-evident answer is to re-use energy and resources on a continual basis. Thanks to technology the ‘circular economy’ is already feasible and becoming cost effective, while green energy is rapidly replacing fossil fuels. However resistance – by political and vested interests – continues to block energy innovation.
