Climate change

As pollutants flow beyond local boundaries, the political difficulties of​ implementing comprehensive, cost-effective control measures are compounded (murakkablashgan).​ Pollutants crossing boundaries impose external costs; neither emitters nor the​ political jurisdictions within which they emit have the proper incentives for​ controlling them.​
Unfortunately, the problems are so important and the potential​ consequences of inaction so drastic (keskin) that procrastination (kechiktirish) is not usually an optimal strategy.
