We can talk about what other folks should or could do but at our house economics and value management meet in the adage, "Waste not, want not." The trick is to find the critical cause and affect relationships. God only knows what the optimal population of Sri Lanka should be in fifty years.

At some point supply and demand will make substituting one product for another a viable change. The task is to make the change in an orderly and safe manner.
