RAIN WATER HARVESTING INTRODUCTION 1. Urban centres in India are facing an ironical situation today. On one hand there is the acute water scarcity due to rise in consumption‚ over dependence and over-exploitation of ground water resources. Added to this‚ there is a lack of a coherent and credible water management policy. On the other hand‚ the streets are often flooded during the monsoons‚ giving rise to a situation of ‘water‚ water everywhere‚ and not a drop to drink.’ 2. This shortage

Energy Harvesting and Nanotechnology | April 28 2011 | Energy harvesting generators are attractive as unlimited replacements for batteries in electronic devices and have been the focus of new researches for past years. This paper reviews the principles behind this technology and their integration to harvest energy. Also proposes a greener alternative for the production of quantum dots before the integration to new technologies. | Nanowires and Quantum Dots | Energy Harvesting with Nanowires

Rainwater pollution is a problem that affects anyone that benefits economically‚ residentially‚ or recreationally from the Chesapeake Bay. This includes people that have businesses that rely on how many aquatic organism they capture to either sell or serve as a meal in their restaurant. Runoff is caused by rainwater that does not percolate into the soil‚ and it carries chemicals and waste that are then drained into the Bay through the storm drains (“Stormwater Runoff”). Plant nutrients like fertilizers

Harvesting and Managing Wild Game Unfortunately some people think of hunters as bloodthirsty savages’ that enjoy the killing of animals‚ with blood-smeared faces and howling over a dead animal. I believe wild animals are here for us to respectfully use to survive. How else would ’ve someone lived 80-years ago without the harvesting of animals? And why should it be different now? Just like any stereotype‚ there will always be those who disrespect and take advantage of what God’s

Poverty continues to be a major issue in Rural Kenya; and a number of social factors influence the level of poverty experienced in surrounding communities. The supply of unclean water‚ the vulnerability of the villagers to water-borne diseases‚ the absence of communication channels‚ and the failure of the community heads to treat infected persons due to lack of sufficient funds to upkeep professional medical services – all give rise to further complications‚ such as high mortality rates and consequently
