Qisqacha ma'lumot
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.
