Problem–Solution — Overconsumption of oil, forests and fresh water

Oil that took millions of years to form is burned in an afternoon, and forests are felled faster than any planting scheme can replace them. Consumption on this scale creates both economic and ecological dangers, but each of them can be reduced if resources are priced and protected properly.

The first problem is scarcity and the conflict it breeds. As the most accessible oil reserves run down, energy becomes dearer, which raises the price of food and transport. Fresh water is a more immediate source of tension: the countries along the Mekong are already in dispute over upstream dams that reduce the flow to farmers downstream. The second problem is ecological. Forests store carbon and hold soil in place, so clearing them accelerates climate change, destroys the habitats of countless species and leaves hillsides prone to floods and landslides. In both cases the heaviest costs fall on the poor and on generations not yet born.

Solutions must target the reason for overuse, which is that these resources are too cheap. Governments should tax extraction and phase out subsidies on petrol and irrigation water, since people conserve what they have to pay for; the revenue can then fund solar and wind power. Shared rivers require treaties that fix how much each state may withdraw, because no country will save water that its neighbour is free to take. Forests are best protected when local people earn more from standing trees than from timber, so schemes that pay communities to conserve woodland often succeed where bans have failed. Individuals have a smaller but real role: buying durable goods and wasting less food curb demand at its source.

In conclusion, the reckless use of oil, water and forests threatens to produce shortages, disputes and irreversible environmental damage. These outcomes are avoidable, but only if governments make waste expensive, cooperate over what they share and give people a stake in conservation.
