Pollution that sits above a region can be blown hundreds of miles away and affect people in another region. For example, the pollution that is produced in China can often cause breathing disorders for people in South Korea. Water pollution can be transported almost as easily. This occurs frequently in some of the river systems that run through several countries. Several countries may depend on the water from the same river to supply their needs, and a contaminated river can spread sickness and disease throughout a large area.
