Acid rain is a widespread term used to describe all forms of acid precipitation (rain, snow, hail, fog, etc.). Atmospheric pollutants, particularly oxides of sulphur and nitrogen, can cause precipitation to become more acidic when converted to sulphuric and nitric acids, hence the term acid rain. Acid deposition, acid rain and acid precipitation all relate [...]

The ozone layer absorbs most of the ultraviolet radiation coming from the sun and is very important for the survival of life on earth. Ozone is a gas composed of molecules of three oxygen atoms (O3). There is a layer of ozone in the stratosphere, which is most dense between 20 and 25 km above [...]

Every increase in air pollution kills a few more people; find Demosthenes B. Panagiotakos, PhD, and colleagues at the University of Athens, Greece.
For every one-unit increase in carbon monoxide, the researchers suggest, there are two or more extra deaths each day. “These health effects occur even at exposure levels below those stipulated in current air-quality [...]

A mixture of pollutants, principally ground-level ozone, produced by chemical reactions in the air involving smog-forming chemicals. A major portion of smog-formers comes from burning petroleumbased fuels such as gasoline. Other smog-formers, volatile organic compounds, are found in products such as paints and solvents. Smog can harm health, damage the environment and cause poor visibility. [...]

Pollution in the ocean is a major problem that is affecting the ocean and the rest of the Earth. Pollution in the ocean directly affects ocean organisms and indirectly affects human health and resources. Oil spills; toxic wastes, and dumping of other harmful materials are all major sources of pollution in the ocean.
Toxic wastes are [...]

What’s an earthquake?
Earthquakes occur because of a sudden release of stored energy. This energy has built up over long periods of time as a result of tectonic forces within the earth. Most earthquakes take place along faults in the upper 25 miles of the earth’s surface when one side rapidly moves relative to the other [...]

1960’s Earthquake
It was in May 22, 1960 when the history of Valdivia was darkened by tragedy. A tremendous earthquake of 8,5 degrees affected the cities of Valdivia and Puerto Montt in Chile. The quake originated 180 feet below the bottom of the sea and 100 miles into the Pacific Ocean.There were not extremely large numbers [...]

The importance of keeping a healthy, clean environment in our cities should be evident to everybody. However, the state of the streets in any city is pitiful: broken trash bags and their content scattered everywhere, excrement from animals whose owners take them for a walk, dirty parks and squares where children are supposed to play, [...]

I personally find passage graves – caves – standing stones and everything else in that frame of things to be truly fascinating, Dunmore Caves in Ireland have become one of the top seven most sought after sights for architects over the last 5 years. Ireland embodies so many wonderful treasures within her, we [...]
