...carbon dioxide emissions resulting from my travels. To quantify this impact, I used an ‘Air Travel Calculator’ that I found online. I was surprised to discover that my three journeys produced similar carbon dioxide emissions to a whole year of car use. In 2005, I drove approximately 16,000 kilometres, which produced around three tonnes of carbon dioxide compared to...

...carbon that provides nutrients to the animals in the river. But if inadequately treated or in excessive quantities, sewage effluent can seriously damage the plant and animal life of a river by reducing the oxygen content of the water. In extreme cases, where the oxygen content is reduced to zero (or nearly so), the river will support very little life, and will become foul...

...carbon dioxide (CO2) 368 ppm methane (CH4) 1745 ppb nitrous oxide (N2O) 314 ppb ozone (O3) 10-100 ppb SAQ 7 Given the information in Table 1, how would you describe the bulk composition of the lower atmosphere? Answer 99% is nitrogen and oxygen (roughly in a 4 : 1 ratio), and most of the rest (0.93%) is argon. SAQ 8 Is any one of these major components a greenhouse gas?...
