    Acid Rain Acid rain occurs when Sulphur Dioxide (SO2) is released into the atmosphere by electricity generation‚ motor vehicles‚ factories and by wildfires and volcanoes. Once released‚ the sulphur dioxide reacts with water to produce sulphuric acid. This has a pH of approximately 2-3 pH. This has a dramatic effect on water dwelling wildlife. Most water dwelling creatures can’t withstand water more acidic than pH 5. This causes the mass loss of life of animals such as trout‚ perch‚ frogs and mayflies

    Melting Ice Caps The Arctic is global warming’s canary in the coal mine. It is a highly sensitive area which is profoundly affected by the changing climate. The average temperature in the Arctic is rising twice as fast as elsewhere in the world (nrdc.org). Because of this‚ the ice cap is getting thinner‚ melting away‚ and rupturing. Here is an example of this; the largest ice block in the Arctic‚ the Ward Hunt Ice Shelf‚ had been around for 3000 years before it started cracking in 2000 (nrdc
