Problems

In Greece, there are many environmental problems such as: ACID RAIN, AIR POLLUTION, SEA POLLUTION, TRASH.


 * Acid rain ** is a [|rain] or any other form of [|precipitation] that is unusually [|acidic], meaning that it possesses elevated levels of hydrogen ions (low [|pH] ). It can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of [|carbon dioxide] , [|sulfur dioxide] and [|nitrogen oxides] which react with the [|water] molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the [|atmosphere] with positive results. Nitrogen oxides can also be produced naturally by [|lightning] strikes and sulfur dioxide is produced by [|volcanic] eruptions. The chemicals in acid rain can cause paint to peel, [|corrosion] of steel structures such as bridges, and erosion of stone statues.
