Acid Rain

Acid rain causes acidification of lakes and streams and contributes to the damage of trees at high elevations (for example, red spruce trees above 2,000 feet) and many sensitive forest soils.



In addition, acid rain accelerates the decay of building materials and paints, including irreplaceable buildings, statues, and sculptures that are part of our nation's cultural heritage.




Effects of Acid Rain

Acid rain is particularly damaging to lakes, streams, and forests and the plants and animals that live in these ecosystems. "Acid rain" is a broad term referring to a mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids.

Pasto

 In non-urban areas, coffee production, mining activities, clearing of land for cattle grazing, all contribute to deforestation and the concomitant problem of soil erosion.




Erodibility of soil is an estimate of the capacity of soil to resist erosion, based on the physical characteristics of each floor.





The World Health Organization reported that 13 million people die annually from environmental causes and denounced this figure could be reduced if reduce polluting factors.
