             Human life on earth relies on the constant use of natural resources to drive, cook, use electricity, and so much more. Energy resources have become a big concern as our current resources are limited and causing problems in the environment like climate change. Energy resources are classified as renewable or nonrenewable. Nonrenewable energy resources come from nuclear materials and fossil fuels. The limited and damaging nature of these sources makes them not desirable for long-term use. Some pluses of natural gas are its more abundant and can help humans make the transition to using renewable resources. Nuclear energy is initially more clean and less harmful to the environment than the other resources combined, but the fact that there is no agreed upon way to get rid of nuclear waste overall end up causing more problems. Renewable energy resources come from moving water, biomass, the sun, wind, and geothermal activity within the earth. All ...

More developed country: -Name: Canada  -Birth rate (per 1,000 population): 10 -Death rate (per 1,000 population) 8 -Rate of natural increase (%): 0.3% -Life expectancy: Male- 80 Female-84 -Fertility rate: 1.7 -Gross national income: $47,280 Less developed country: -Name:  Niger -Birth rate (per 1,000 population): 47 -Death rate (per 1,000 population): 9 -Rate of natural increase (%): 3.8% -Life expectancy: Male- 60 Female- 63 -Fertility rate: 7% -Gross national income: 1,030       The information above is presenting demographic data about the two chosen populations of Canada and Niger. "Demography studies how human populations grow, shrink, and change in terms of age and gender compositions using vital statistics about people such as births, deaths, populations size, and where they live" (Mutiti, et al, pp.16). The information comes from the population reference bureau and is utilized to make projections on population increase/decrease over time (Population Refe...

  The Interconnections of energy and energy transformations in ecosystems      Energy exists in many different states, and is constantly making changes from one state to another. When energy is transforming it must obey the laws of thermodynamics, as they are universal. The first law is the law of conservation of energy, which states that energy cannot be create nor destroyed, only transformed. The second law of thermodynamics says the transformation of energy is always inefficient, and that life and ecosystems can't exist without a continuous energy input from outside sources (n.d.1).      All ecosystems have an energy budget, which focuses on the absorption of energy by photosynthetic organisms as well as the transformation of fixed energy through the trophic levels of the ecosystem. Trophic levels are the different levels of a food chain. Moving up in levels of the food chain results in a loss of about 90% of the starting energy at each transformati...

       Water is a finite resource on planet Earth. On average the American citizen uses about 80-100 gallons of water in just one day (Water questions and answers)! With only 2% of all water on Earth being viable for human consumption, and less than 1% of that actually being accessible to humans, it is important that we become aware of out water usage is order to cut down and help conserve this precious resource (Mutiti, et al.). The following data presents my water usage over the last three months as is stated on my San Antonio Water Systems (SAWS) monthly bills, as well as the calculations that brought me to my daily water usage, and some projected daily water usage calculations from water use calculators I found online.     1.       My household water usage over the last 3 months                        June- 2,244 gallons (gal)           ...

Problem-  To clearly define the problem there is a level of understanding that is needed in order to fully comprehend the issue. Firstly, there is an atmosphere surrounding earth which is comprised of key gases including nitrogen, oxygen, carbon dioxide, and other trace gases (Freedman, Chapter 3, pp. 52-53). Some of these trace gases are greenhouse gases (GHG's) like methane, and nitrous oxide (EPA, n.d.3). When the sun sends solar electromagnetic radiation through space it penetrates our world's atmosphere and gets absorbed by the earth's surface where it is then re-radiated in the form of long-wave infrared radiation. If the atmosphere were non-existent, these waves of infrared radiation would scatter out into space and would drastically reduce the temperature of the earth. This is where our greenhouse gases come into play. GHG's are effective at absorbing this infrared radiation and get heated as a result. Some of this thermal energy is then re-radiated in all direc...

                                       ( www.pophistorydig.com/topics/cuyahoga-river-fires/.) 1. Point of view- The point of view for this video comes from that of individuals who were actively present in the clean up process, as well as from individuals who are experts of their fields.  Captain Wayne Bratton was a gentleman who first hand saw and lived through the effects being caused by river pollution. He remembers a time when the sights and horrid smells were seen as signs of job prosperity, and they were thought to just be a normal part of the day, but now knows that things are different in the way people view pollution (Andrew J Tobias). Bob Wysenski is a current member of the Ohio EPA and was a part of the initial clean up crew for the river who too part in Remedial Action plan meetings with the International Joint Commission   Jenn Greiser who is the senior natural ...
