The central theme of this course is resource sustainability. The meaning of resource is anything from the environment that meets our needs and wants. Meanwhile sustainability is the ability of the earth’s natural systems, cultural systems, and economic systems to survive and adapt to changing environmental conditions indefinitely in the face of exponential population growth. In class we studied five ecosystems that were vital to resource sustainability and the continuance of life on planet earth. These five cycles we studied were: the water cycles, the carbon cycle, the nitrogen cycle, the phosphorus/ rock cycles, and the sulfur cycle.
First I will describe how the water (hydrologic) cycle contributed to resource sustainability and to continue life on planet earth. The water cycle filters, cleans, and transports fresh water to organisms throughout the entire planet by using energy from the sun. The water cycle includes the processes of transpiration and evaporation to receive fresh water from the oceans or ground into the atmosphere, the cycle also includes precipitation and condensation to bring it back to the earth’s surface. According to SSWM (sustainable sanitation and water management), “humans significantly influence the global water cycle, both quantitatively and qualitatively. The more humans use water, the more they also influence water quality. Nutrients from fertilizers and from disinfecting systems are carried to aquatic ecosystems. This causes pollutants,…
