Qualitative research refers to a family of philosophies which are characterized by positive evaluations of science and scientific methods. Qualitatively, variance can be expressed as the real or positive number in many situations. When a variance amounts to zero, this is an indication that all the scores for that particular variable are the same or are similar.
Countries all over the globe have been impacted by climate change arising from environmental degradation, Australia being no exception. Over the past century, the temperature in Australia has risen by 0.8ºC, with the minimum temperatures rising quicker when compared to the maximum. On the other hand, the western parts are receiving lesser rain. An increase in coral mortality and bleaching in the Great Barrier Reef have been attributed to a rise in the sea surface temperature. Although the rise in the sea level in Australia has varied across its regions and has remained below the global average, the Snowy Mountains have seen a fall in snow cover. According to CSIRO, when compared to 1990 figures, the average annual temperature by 2030 could rise between 0.4ºC to 2.0º C and 1.0ºC to 6.0ºC by the year 2070 (CSIRO, 2001). The level of climate change in the future remains uncertain and debatable, although it is certain that fluctuations in rainfall, tropical cyclones, and El Nino Southern Oscillation events, as well as decreased snow cover and duration can be expected.

This paper presents the design of a solar powered refrigeration system. The design of the system takes into account the solar sorption principles which include both the absorption and adsorption. Research has been conducted and it has been proven that the design and implementation of solar refrigeration system comes with several advantages. It helps in meeting the demand for energy conservation and the protection of the environment.
Hunger and famine are two natural calamities that have serious and devastating effects on the life in this planet. Famine is a long season without rain, which leads to a decrease in agricultural productivity. Of course, this leads to hunger. In the various economies around the world, man is engaged in trading activities. Agro-business is one of the trading activities. This essay seeks to establish the position that agro-business exaggerates hunger and famine rather than help in curbing it.
