Finland is one of these countries that care much about the environment, being among the least polluted countries in the world. The air pollution control has made air quality much better in recent decades. Finland is doing great in other fields as well, having reduced industrial and agricultural waste to a minimum recently. Though that was not always the case. Some thirty years ago Finland had a great issue of polluted waters exactly due to the industrial development. But things seem to be going great nowadays.
