The different sources of drinking water comprise of streams, ponds, rivers, lakes, groundwater wells and springs. San Jose Municipal Water System, CA, buys treated surface water from the Santa Clara Valley Water District that imports water chiefly from San Luis Reservoir, Lake Del Valle and South Bay Aqueduct (Water Supply, 2016). It also buys treated water and Hetch Hetchy water from San Francisco Public Utilities Commission that gets its water supply from Hetch Hetchy Watershed. San Jose Municipal Water System is run by City of San José, Great Oaks Water Company, and San Jose Water Company. Although the water distribution system is inspected at different locations by state-certified laboratory and Municipal Water System staff. The general concerns related to the quantity and quality of water sources such as streams, ponds, reservoirs, rivers, lakes include the naturally-occurring minerals and substances that get dissolved in water due to the presence of animals or human activity, microbial contaminants, inorganic contaminants, pesticides and herbicides may come from different sources.
Fisher, because of its long, slender body can evade detection by humans. The Fisher is known for its ferocity and is a close relative of the wolverine and badger. The species is esteemed in tribal ceremonies and has coexisted for thousands of years on Hoopa ancestral land. Its population is dwindling in California and action is already on to save the endangered forest-dwelling animal. The major reduction in its population is attributed to predation by bobcats and exposure to anticoagulant rodenticide poison. The species falls under the Endangered Species Act, and efforts are being made to understand the habitat of fishers. The trees are being conserved for female fishers, and efforts are made to restore their habitat (Find Endangered Species, 2016).
For conservation of life on Earth, one has to understand the environmental conditions first. The variable used to describe weather and climate include the wind speed, temperature, atmospheric pressure, cloud cover, humidity, etc. Latitude and Longitude are the major components that influence weather in a particular area. Another important factor is the average tilt, 23.5 o, of the Earth’s axis that leads to seasons. The angles made by the slanted sun rays will decide the amount of energy amassed by the earth. As life on the planet is closely related to the weather and climate, it is essential to keep in mind the important factors that impact the environmental conditions (13.1 & 13.3 A Closer Look at the Earth and Why we have Seasons, 2016). Today, there are several aspects of sustainable agriculture and the central concept lies in discouraging the industrial approach to food production that surfaced during the 20th century. Today, the food has become more affordable and abundant, because of sustainable agriculture. However, there have been steep costs to pay with depleted and contaminated resources of soil and water, erosion, deforestation, loss of biodiversity and decline of family farming. Sustainable agriculture embraces the philosophy of sustainability beyond growing food (Sustainable Agriculture, 2016). It encourages a vast range of farming techniques that are holistic, organic and biodynamic. Critics of sustainable agriculture state that the methods employ higher land use and result in lower crop yields. Still, there is evidence that sustainable farming can be as productive as traditional industrial farms. What is wrong with the industrial, agricultural practice is that it consumes fossil fuel and topsoil at unsustainable rates and leads to pollution, environmental degradation, and soil depletion. The proliferation of such farming methods can create environmental and public health concerns.
