"We conducted ceremonial gatherings and visited sacred sites," said Masso. "Pools in the river provided an abundant fishery to families and there was a village at the mouth of the Kennedy River."
In this video Mark Koh explains about alternative energy sources that can be used as alternative options to fossil fuels, how they work, and how they are used today. Some of the more common sources are: Solar, Wind, Hydro, and Geothermal energy. The video will only explain briefly about solar, wind, and hydro energy sources.
Current energy sources will not be able to sustain our growing society. We must look to alternate energy sources for the answer.
Alternate energy sources must replace our traditional energy sources because they are sustainable for our lifestyles. Since the age of industrialization, we have relied heavily upon traditional energy resources (mostly the burning of fossil fuels such as coal, oil, and natural gas). These traditional resources have shaped our culture as well as our development. However, when these resources are used to produce energy, they negatively impact our delicate environment. They are also nonrenewable and will one day run out. However, we may solve the problem of our depleting resources through current technology, which promise new alternative methods to produce energy. Using these alternative resources will greatly increase our sustainability.
