The world depends heavily on fossil fuels such as coal, oil, and natural gas for energy, and while the worlds population and energy consumption continue to increase, the non-renewable resources we need to produce energy will eventually be depleted. According to the U.S. Energy Information Administration, the supply of oil left in the world will last us twenty five more years. One may say that twenty five years is a long time, and by then new sources of fuel will surely have replaced the nonrenewable sources we currently use to meet our energy demands. This, however, should not be the approach the world takes to solve this issue. Instead of hoping that the problem will solve itself in the years to come, it is our duty as a planet to†¦show more content†¦Through anaerobic digestion, methane gas is produced, which can then be refined for use as fuel. Biomass can also be converted into ethanol or biodiesel, which can serve as substitutes for currently used transportation fuels, decreasing the reliance on fossil fuel. Crops such as sugar cane or corn can be fermented to produce ethanol, while natural oils from palms or soybeans can be used to create biodiesel. Another way to harness the energy of biomass it to burn it. Even though the combustion of solid biomass may not be as environmentally sound as fermenting and refining it to make fuel, combusted biomass still emits less pollution than the combustion of other fuels such as oil and coal. The combustion of biomass can be used domestically to heat homes in place of oil or gas heaters, or even industrially to provide electricity to run machinery. With less of a negative impact on the environment, the use of biomass to create energy can decrease the worlds reliance on fossil fuels, and decrease pollution through the conversion of waste into a usable energy source. The use of biomass as an alternative energy source to fossil fuels is considered to be beneficial to the environment because it is believed that it will reduce the increase of carbon dioxide in the Earths atmosphere. Biomass is considered a carbon neutral source of energy because the carbon released into the atmosphere will be absorbed again when new plants/biomass grows in aShow MoreRelatedNuclear Fusion And Nuclear Energy Essay1638 Words   |  7 Pages ¬Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together. Nuclear energy can be used to make electricity. But first the energy must be released. It can be released from atoms in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. This is how the sun produces energy.

Plato s Meno As A Socratic Discussion On Human Sexuality...

Plato s Meno is a Socratic discussion on the definition of human virtues where the main participants are Socrates and Meno. Other speakers in the dialogue include an Athenian politician, one of Meno s slaves, and Socrates’ prosecutor Anytus, who is a friend to Meno. Meno wants to understand the broad definition of human virtues and while visiting Athens he initiates the dialogue on virtues with Socrates. The discussion begins with Meno inquiring from Socrates whether virtues can be learned. Meno argues that, according to the Georgian’s, the attribute is defined differently by different people, and there is no common way to define it so as to apply it to all human beings. In response, Socrates argues that the Georgians do not understand the real meaning of virtue and in his opinion that some attributes are common to all human beings. Socrates also rejects the idea that virtues depend on human sexuality and age and insist that there are common attributes in humans. The conversation between the two becomes an argument on about the perfect definition of human characteristics. In essence, this paper discusses the critics in Plato s Meno that led to a senseless conclusion on virtues as it was significantly contributed by Socrates. As well, the paper will support the argument that the agreement between Socrates and Memo was based on distinct ideas. A misunderstanding starts when extracting virtues from the human characters. Meno, defines quite a number of human virtues, but

Life, the universe and everything else Essay Example For Students

Life, the universe and everything else Essay before and after DarwinIn the beginning was God.And everything was simple and easilycomprehensible. You had God to worship, the Ten Commandments to follow andnothing to worry about. Because God was responsible for everything and Hewas supposed to take care for you if you truly believe in Him and pray hardenough. And there were no questions without an answer because everythingwas encoded in one word God. And although man knew he was part ofsomething greater than himself, he was feeling important because God hadcreated everything to serve man and man only.There were no questionsabout the meaning of life, no speculations on morality, no doubt about theright way in life. Some things never change. But some things do change. George BernardShaw said that: The reasonable man adapts himself to the conditions thatsurround him The unreasonable man adapts surrounding conditions tohimself All progress depends on the unreasonable man. And CharlesDarwin was one of these unreasonable men, who carry the progress on theirshoulders. He took the ideas and findings of early scientist, the observations ofdifferent farmers and his own personal experience about the diversity andfitness of life on earth and put together the foundation of modernevolution theory used by scientist today. Darwin presented a vast amount ofevidence showing that all living things ultimately descended from a few oreven one type of ancestor. The greatest naturalist also presented his ideaof how this descent with modification, or evolution, works; it was callednatural selection. Natural selection was considered a force for thealteration of species. In essence, in the battle for their survival, onlythose individuals best adapted to their environment are more likely tosurvive, reproduce and pass on their genes. Favourable or beneficialmutations of species are favoured and retained, while harmful or uselessones are rejected and lost. So, across generations, different speciesundergo adaptations through the gradual accumulation of useful variations those which help them better survive and successfully reproduce in theirparticular environments. Over time, in a series of tiny, steady, andimperceptible steps, beneficial mutations accumulate and the result is anentirely different organism. Not just a variation of the original, but anentirely different creature. Suppose a member of a species developed afunctional advantage (it grew wings and learned to fly). Its offspringwould inherit that advantage and pass it on to their offspring. Theinferior (disadvantaged) members of the same species would gradually dieout, leaving only the superior (advantaged) members of the species. Naturalselection is the naturalistic equivalent to domestic breeding. Over thecenturies, human breeders have produced dramatic changes in domestic animalpopulations by selecting individualstobreed.Breederseliminateundesirable traits gradually over time. Similarly, naturalselectioneliminates inferior species gradually over time. Darwin proposed sexualselection to explain the accentuation of features, not always essential oreven beneficial to survival, that increase a species chance of securing amate and breeding. Moreover, sexual selection can produce individuals withsuch elaborate ornaments that they must be either energetically costly todevelop, costly to maintain, or even lead to a direct survival cost for theindividual that bears the ornament. For example, the male peacocks immenseand lurid tail attracts female peacocks. But imagine a population that hasnot yet evolved elaborate sexual ornaments compared to the population,which is derived from the original stock, but males have now evolvedelaborate ornaments. In the derived population, many males die due toreasons of sexual selection owing to their ornaments. The average fitnessof individuals in the initial population is higher because fewer males dieselective deaths compared to the number of males that die selective deathsin the sexually-selected population. And the result is declinati on in theaverage chance of survival of the population over time. .ue995ae7a71d6d310ea9f7d00130169d6 , .ue995ae7a71d6d310ea9f7d00130169d6 .postImageUrl , .ue995ae7a71d6d310ea9f7d00130169d6 .centered-text-area { min-height: 80px; position: relative; } .ue995ae7a71d6d310ea9f7d00130169d6 , .ue995ae7a71d6d310ea9f7d00130169d6:hover , .ue995ae7a71d6d310ea9f7d00130169d6:visited , .ue995ae7a71d6d310ea9f7d00130169d6:active { border:0!important; } .ue995ae7a71d6d310ea9f7d00130169d6 .clearfix:after { content: ""; display: table; clear: both; } .ue995ae7a71d6d310ea9f7d00130169d6 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ue995ae7a71d6d310ea9f7d00130169d6:active , .ue995ae7a71d6d310ea9f7d00130169d6:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ue995ae7a71d6d310ea9f7d00130169d6 .centered-text-area { width: 100%; position: relative ; } .ue995ae7a71d6d310ea9f7d00130169d6 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ue995ae7a71d6d310ea9f7d00130169d6 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ue995ae7a71d6d310ea9f7d00130169d6 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ue995ae7a71d6d310ea9f7d00130169d6:hover .ctaButton { background-color: #34495E!important; } .ue995ae7a71d6d310ea9f7d00130169d6 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ue995ae7a71d6d310ea9f7d00130169d6 .ue995ae7a71d6d310ea9f7d00130169d6-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ue995ae7a71d6d310ea9f7d00130169d6:after { content: ""; display: block; clear: both; } READ: Environment Report: Tidal Power In The Bay of Fund EssayDarwins ideas turned the world upside-down and changed the way weunderstand ourselves and everything around us radically. His most infamousidea was that human beings evolved from apes through a series of gradualsteps. Its here that modern evolutionary psychologists pick up from whereDarwin left off. Humans and all their associated habits and behaviours,they suggest, can be explained as products of evolution. He implied thateven attributes, previously identified as uniquelyhuman,suchasintelligence and emotion could come about through natural selection. Before that no one could challenge Gods authority but Darwin did itand was very successful in this undertaking, although it wasnt hisintention. He did believe
