Acid Rain

It possesses elevated levels of hydrogen ions(it has low pH level). Acid rain is caused by emissions of carbon dioxide, sulfur dioxide and nitrogen oxides, which react with water molecules. Distilled water(doesn't contain CO 2), has pH level 7. Liquids with pH level less than 7 are acidic, liquids with pH level greater than 7 are alkaline. Unpolluted rain has a pH level over 5.7, s...

Essay on water pollution, global warming, acid rain, deforestation, intensive farming

As the world has industrialized and its population has grown, the problem of water pollution has intensified. The simple fact that millions of people live along coastlines and near rivers means that these bodies of water are likely candidates for heavy and destructive pollution. It is hard to know now what our oceans will look like in the future. Just how damaged they will be by pollution is uncertain. Acid rain The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible g...

Levimuusika

Uimastid olid olnud ameerika ühiskonna salapaheks juba rohkem kui veerand sajandit ning röövinud jazzmuusikutegi hulgast mitu silmapaistvat annet. Hallutsinatsioone esilekutsuvate narkootikumide toimes hakati nägema lahendust ülepääsmatuna paistnud probleemidele. Ilmale tuli rocki kõige ebardlikum vorm: psychedelic rock (hinge kahekordistav, avardav. Kreeka keeles psyche- hing ja delos- selge, nähtav.). [Variantnimed: acid rock (slängis uimasti ) -, head music.] Ülistatud “teadvuse avardum ine” (psühhedeelia) oli tõelik kust m oonutav haiglane sonim ine, psühhoosi seisundis või hallutsinatsiooni mõju all viibimine. Sellise seisundi saavutamiseks keerasid mõned rockmuusikud helitugevuse maksimumini. Sellest saigi muusika tähtsaim komponent. Niisugune muusika ristiti heavy rock’iks. Kõlapildis said tähtsa koha efektiseadmed. Võeti kasutusele light s...

Environment

The ozone layer around the Earth, there is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals also cause acid rain, that destroyes plants, rivers, lakes and buildings. Acid rain can travel thousands of miles, so pollution in one country can become acid rain for another country. So how to avoid the worst? Lets talk about cars, which are the main means of transport in our everyday life, they are useful and take us to the place, where we want to go. But lets be honest, they have also negative aspects. Like heavy traffic in the morning, while you are goin...
