SUSTAINABLE USE OF RESOURCES There are two kinds of resources – finite and renewable. Finite resources, such as coal, oil and minerals, will eventually run out. These we must use carefully and wisely. We must give ourselves time to find substitutes, to avoid sudden disruption that shortages bring to already volatile markets. Renewable resources include the atmosphere, water, soils, plants, livestock, and indeed we humans and our own labour. We can tap these resources, but not so much that they cannot regenerate themselves. Soils must be kept fertile, forests managed, water kept clean and the atmosphere in balance. Waste and pollution must be kept below levels at which they can harmlessly be absorbed. Other resources are based on cosmic energies – the sun’s heat and light (which drive the climate, winds and rain, and enable plants to grow), gravity, tides, and geothermal energy. There is more than enough of these to meet our needs, and we have the technology to exploit them. Furthermore, working at the local and regional levels adds immediate and tangible benefits to the long-term imperative of global sustainability. UNSUSTAINABLE DEVELOPMENT It maximises local productivity, brings local As the world’s population rises, with aspirations by people for a higher standard employment, and reduces the leakage of wealth, of living, the strains on the environment continue to increase. and helps bring communities together with a real stake in their collective future.
