Human Activity and Energy Sources - 968 Words

Earth’s resources, for instance water, productive farming land and energy, outlines the basic foundations of our continued existence on earth. However, with the continued human activities, for example logging and charcoal burning, these resources are quickly being depleted. Human inhabitation and increased consumption of the natural resources is resulting in untold destruction. The climate change being experienced globally, the rapidly depleting freshwater catchments, the dwindling forest cover, the ever reducing fish ‘stash’ in our seas and oceans and farmland dereliction are some of the effects resulting from human occupation and activities. Poaching, another human activity, is resulting in the extinction of certain animal species thus†¦show more content†¦Sustainability is a model that has been developed to ensure that human life is not threatened by continuing depletion of the natural resources. This model has also been adopted in order to ensure that the ecosystem is protected. Sustainability is being promoted in order to ensure that human beings and the environment coexist within certain set restrictions so as to ensure that the ecosystem continues to support life. In addition, this model ensures that humans understand the relationship which manages the balance between their activities on the ecosystem. Through sustainability, human beings will be able to utilize the available natural resources sparingly with the view that future generations are depending on it too (Maria and Luciana 3). Some of the renewable sources of energy are solar, hydropower, biomass and wind. The use of these energy sources ensures that the ecosystem remain self serving and thus able to sustain human life (Diane and Shubhayu 12). The uptake and use of solar energy is yet to be fully utilized because in America, the percentage of people using this energy is minimal. In the United States, solar energy represents almost a half of one percent of the total electricity use, a number that is insignificant (Diane and Shubhayu 12). The human population is yet to realize that solar energy can be used extensively in both heating and lighting. Moreover,Show MoreRelatedGlobal Environment Essay1298 Words   |  6 PagesThe U.S and the European Union are heavily dependent on expensive imported energy resources that place a big burden on the economy and air pollution is becoming a great environmental concern. In this regard, renewable energy resources appear to be the one of the most efficient and effective solutions for clean and sustainable energy development. In order to increase the use of clean energy, we recommend a Cap and Trade policy: A government-mandated, market-based approach to controlling pollutionRead MoreThe Health Fitness Human Performance Essay1498 Words   |  6 PagesHealth Fitness Human Performance One of the most important parts of an athlete’s training regime is nutrition because of its role in human performance. Athletes need to focus on nutrition because the failure to ingest adequate calories can contribute to a lack of vital macro and micro nutrients. Moreover, nutrition is a crucial element in any athlete’s training regime given the influences of food on a person’s physical mankind. Throughout history, certain foods have been regarded as essentialRead MoreCauses And Effects Of Pollution1578 Words   |  7 Pageshow it’s destroying earth and how it helps the greenhouse effect on Earth’s atmosphere. There are many different sources of pollution, even some that may not seem likely to produce so much. There are many causes of pollution in the environment. Some include natural sources of pollution and some are caused by manmade sources of pollution. Whether they are natural sources or manmade sources, they all contribute to the destruction of our atmosphere and rising CO2 levels which cause the â€Å"greenhouse effect†Read MoreAlternative Sources Of Alternative Energy Sources1123 Words   |  5 PagesRough Draft: Alternative Energy Sources Imagine a world where sea levels have risen, a world where extreme weather happens more often and with more intensity, and a world that has very few species of animals left due to mass extinctions. (Environmental Protection Agency) But that future is still avoidable. The answer is renewable energy sources. Alternative energy sources are sources of energy that does not use fossil fuels, and generally are clean and renewable. (Jessa) Some examples include solarRead MoreThe Causes Of Global Warming Essay1705 Words   |  7 Pagesand consequences of the global warming with the aim of presenting solutions to the problem. Moreover, learning of the causes provides the human race and environmentalists will spread the awareness to more people helping them to reduce their activities that contribute to global warming. With the inquiry, there is the concern that human beings and their activities are indeed the leading contributors to the causes of the global warming. The consequences of global warming have been hugely manifested inRead MoreGlobal Warming : The Persistent Rise Of Air And Sea Temperatures1212 Words   |  5 Pagestemperatures in the last few decades raising major concerns globally. If the current trends persist, it may be difficult for the earth to sustain life in the next 200 years. Global warming emanates from both human and natural causes. The current state of global warming is mostly related to human causes, as natural causes are rare. Natural causes include volcanic eruptions, changes in solar output, and variation of the earth’s position altering its distance from the sun (Singer Avery, 2007). VolcanicRead MoreClimate Change Is An Important Issue That Concerns Humanity999 Words   |  4 Pagesimportant issue that concerns humanity. Climate change refers to an increase in average global temperatures. Every day, the enhanced greenhouse effect continues to advance, which significantly influences Earth’s long-term climate. In addition, hu man activity is also contributing to the increase of global warming and is already leading to harmful consequences. Some people believe that global warming is not occurring and the heating of the globe, is just a part of the Earth’s natural cycle. SeveralRead MoreGlobal Warming And Its Effects1312 Words   |  6 Pagessuch countries is on low altitude areas. This position makes developing countries to be direct victims of floods from the melting snow at high altitude areas. A lot of scientific research associates global warming with the numerous irresponsible human activities such as industrialization in the developed countries. These industries emit a high content of greenhouse gases like carbon into the atmosphere on a daily basis. The resultant effects are very alarming and therefore, need to be put under controlRead MoreMarine Ecosystem1607 Words   |  7 Pageson global warming, the fact remains that humans have an impact on the marine ecosystems through waste from che micals and debris polluting this vast renewable resource. Based upon current scientific evidence, emissions of greenhouse gases from human activities are projected to cause significant global climate change during the 21st century. Such climate change will create novel challenges for coastal and marine ecosystems that are already stressed from human development, land-use change, environmentalRead MoreClimate Change And Global Warming1371 Words   |  6 Pagescomprehend how human activities contribute towards climate change and global warming, we have to truly understand the science behind this phenomenon. First of all we need to clarify what anthropogenic climate change means. This refers to the change in the amount of greenhouse gases and aerosols in the atmosphere as a result of unsustainable human activity. Greenhouse gases and aerosols change incoming and out-going solar radiation, thereby affecting the earth’s climate. The major human activity that contributes
