Is it possible for somebady to translate into polish:
All these changes have made more acute a longstanding asymmetry: national borders are a boon for traffickers and a nightmare for law-enforcement agencies. Borders allow for the price differences that yield rich profits to smugglers with the ability to transport goods across them. (While in 2004 the average annual income of a poppy farmer in Afghanistan was just $1,700, a kilo of heroin fetched more than $39,000 in the United Kingdom.) Borders also provide a convenient legal shield for smugglers once they cross over to another jurisdiction. Governments have a very hard time collaborating with other governments; their natural habitat is inside their national borders. In contrast, traffickers are most effective when operating across borders—which makes them in many ways better suited to today's world.
