Thinking about ozone
Article Abstract:
Ultra violet (UV) energy both creates and is potentially destructive of ozone. Ozone depletion is caused either when chlorine atoms are released by UV energy reacting with natural chloromethane or when artificial pollutants increase the destructive elements. Gases released during volcanic eruptions may also affect stratospheric ozone. Ozone hole refers mainly to the ozone depletion over Antarctica during spring. Research is being done on the extent of impact of ozone depletion on plant and animal life. The ozone problem can be solved by taking steps such as checking vehicle and industrial emissions, reducing energy needs and controlling pollutant usage.

Time and temperature
Article Abstract:
Global warming is caused by the absorption of infra-red rays by water-vapour and carbon dioxide. Gases such as methane, nitrous oxide and ozone influence the greenhouse effect. A study of the global patterns of air temperature suggests that mean air temperature is likely to be warmer, whether for natural or man-made reasons. While floods are likely because of increasing storm activity, global warming can be beneficial for some places if shifts are made in agricultural habits. Volcanic eruptions and cloud formations may reverse the global warming process.

Earth's vital energy flows
Article Abstract:
Solar energy, geothermal energy and the energy from the evaporation and condensation of ocean water have a flow pattern influenced by the gravitational force of the earth. An ecological imbalance is caused when these flow patterns are altered by human beings to use these energies. Man-made changes can have a powerful impact which can cause disruptions of the environment. The manner in which nature responds to such changes is worth analysis.
