It is the Earth Day today. The day for global environmental questions has been around since 1970. During that time a couple of environmental problems have been more or less solved in Western Europe, but many global questions have emerged. Acid rain is not a problem any more in Europe - smoke cleaning standards have abolished it. The ozone hole has started to shrink, because the most harmful chemicals have been banned. The levels of persistent organic pollutants in the Baltic Sea have dNorsu.jpgecreased markedly as water treatment has become strictly required. These examples show that environmental problems can be solved if it is deemed necessary. Today's urgent environmental problems are climate change, and associated with it the availability of water. Solving the climate problem requires many different actions, but two are clear, changing our energy use habits, and increasing carbon dioxide fixation by plants. The most effective solution to the plastic waste problem would be to make waste collection effective everywhere and influence the attitudes of people. In the present situation, if it weren't for plastics, other types of waste would be filling our beaches and seas. Finally, the Earth is facing mass extinctions. For big mammals a solution is to stop trophy hunting completely, but in addition to the mammals, also other species are suffering from the decreased availability of suitable habitats and deaths caused by pesticides and other environmental toxicants.
