Human Activity and Energy Sources

The number of wild animals on Earth has halved in the past 40 years . Creatures across the land, rivers, and the seas are destroyed as humans killed them for food in unsuitable numbers, while polluting or destroying their habitats.

In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on

Solar Resources are not only affecting the GDP for power, but in other areas as well. Over a million residential water heaters are replaced each year and more are being replaced by using solar power. The solar power is given an opportunity in use solar power as the primary heating source for homes and commercial buildings. Which can increase the amount of GDP that is spend, yearly on solar and a large share of the energy market.

The term sustainability is one that been conceptualized since the early civilizations of humans inhabited the earth. During those primative times, everything that allowed civilizations to thrive came from the earth. Humans during those times were more more in touch with their reliance on the environment. In today's society, the reliance on our natural environment seems much further away due to our insulation from modern conveniences. Nevertheless, this conception could not be further from the truth; we are more reliant now on the world's renewable resources than ever before.

In order for one to further understand the importance of solar energy, the problem of global warming must be explained. As defined by Webster’s Dictionary, “Global Warming” is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. With an average increase in atmospheric temperatures, our planet is slowly deteriorating. In order to stall or halt this global destruction, countries must turn to solar energy as a cleaner alternative to the depletion of fossil fuels. Solar energy creates a homeostasis for the climate. Due to its ability to decrease global climate changes, solar power can address global warming in several ways.

Sustainability is a topic that has become very important in recent years. Sustainability is defined as, “the ability to continue a defined behavior indefinitely.” ("Finding and Resolving the Root Causes of the Sustainability Problem", 2014)

One of the biggest problems facing the global population of the world today is ecological sustainability. Ecological sustainability is when the rates in which renewable resources’ are harvested, population is increases and non-renewable resources are depleted can be continued indefinitely. If all of these aspects cannot be continued indefinitely then ecological sustainability

According to Morris (2003), Humans are also killing the animals for food and this choice also destroys the natural habitat. Many humans are making the choice to catch fish faster than the oceans can restock. When people choose to destroy these animal’s homes, it has a negative effect on the food chain. When one sees the impact of human interaction on the natural habitat, society must realize that they have a responsibility to do something because our future as a species on this planet is in jeopardy.

The dictionary meaning of sustainability is “the ability to be maintained at a certain rate or level”. In real terms this means we need to treat and respect the environment and keep it at a level that the is still reasonable to the human eye. This is so that future generations will be able to enjoy the beautiful serenity in its respectful state.

The term sustainability is defined as endurance of a system. Likewise, the sustainability of energy sources is the provision of energy sources without compromising for present and future use. The major sources of energy are natural resources such as fossil fuel and coal. These natural resources are limited in our universe. Therefore, there is maximum compromise in the use of these resources. To sustain the lives of future generation, alternative sources must be created. The energy which can be provided without compromising is renewable energy sources and they are reproducible. For instance: wind energy, geothermal energy, solar energy, bio energy, etc. Due to increased urbanization, mobility, and economy; necessities of renewable sources

Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C, when the sun’s heat was concentrated by glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental, economic, psychological and ethical implications for our society. Actions taken by companies and individuals to increase the use of solar technology will create good local jobs, improve our environment and reduce our dependence on foreign oil while doing what’s ethical and moral for our society.

This paper was constructed to give an overview of the vast majority of species that are disappearing and have disappeared from the earth. With informative knowledge and accurate numbers the reader was introduced to the different ways that animals are becoming extinct, deforestation, overpopulation, economic prosperity, population growth, urban environment, global perspective and science and ethics. Each of these is affecting different species at different rates, but what was concluded by comparing numbers is that humans are truly responsible for their actions and the actions of causing the exaction and endangerment of animals. Humans are the

1). So, why is solar energy not being used? Currently, solar energy accounts for 8 TWh, terawatt-hour, of the more than 10,000 TWh of electricity produced by the countries in the OECD, Organization for Economic Cooperation and Development (Resch and Kaye, 2007, pg. 63). When comparing these two, energy produced by solar energy is less than one percent of their total energy use. Solar energy is a fantastic resource that is not being taken advantage of all around the world. Resch and Kaye (2007) state that “... these low- carbon technologies could provide more than 30 percent of the world’s energy supply in aggregate by 2040” (pg. 63). In addition, if the world switches to solar energy completely and only are able to harvest 10% of the energy actually emitted by the sun, that 10% of energy would equate to 200 times more than the energy obtained from fossil and hydroelectricity (Emetere, Akinyemi, Edeghe, 2016, pg. 2). Solar energy not only has the ability to produce very large amounts of energy and is more environmentally friendly, it is becoming more and more cost effective. The cost for solar energy is currently decreasing 10% every year (Jurich, 2015, pg. 32). Currently, single solar modules are 3-5 dollars per watt; however, if this technology gets more support and funding, it would be cost-competitive with the current energy cost for the United States (Resch and Kaye, 2007, pg. 63-64). Solar

Solar power happened to be the first source of energy that was ever available to mankind. The amount of dependency on solar power is tremendously high. On the downs side, it is

Today more and more wildlife is becoming extinct or in danger of extinction for various reasons. There are different types of wildlife exploitation, with varying effects on the welfare of the animals involved< worldanimal.net, n.d>. However, we should notice that wildlife is killed and exploited by us. In other words, Human beings are destroying the planet.
