“The worst threat to man is man himself.” These words, from the recent publication The Great Pearl of Wisdom, are from the open mind of Bangambiki Habyarimana, a man known for his work in the fight against HIV and AIDS. His blatant, cut and dry point of view is a very simple way of stating that humanity has the power to destroy itself, whether directly or indirectly. Indirectly, the human race may bring upon its own doom through the destruction and degradation of its caregiver, provider, and home: the Earth. One of the biggest issues in the modern world is climate change, which is directly related to carbon dioxide emissions and the greenhouse effect. The greatest contributor of CO₂ emissions is the use of fossil fuels, such as coal, oil, and …show more content…
Fossil fuels are known as non-renewable resources; the amount in the Earth is limited. On the other hand, renewable sources of energy, like solar and wind, are those that will not be depleted despite their continued use. However, solar energy is difficult to harness and wind energy is not very efficient. The clear choice of renewable energy is water. The Earth has plenty of water to use for power. After all, it is because of its great quantity of water that Earth is nicknamed the “blue planet.” Hydropower is entirely renewable because it is driven by the natural Water Cycle. Lakes and rivers that are used for hydropower will not simply run out because they are constantly being refilled by rainwater. In addition to being renewable, hydropower is superior to other energy sources because it is completely clean of carbon emissions. Once fully functional, dams power themselves and give off no excess gases. Power plants burn coal and pour unthinkable amounts of greenhouse gases into air. Hydroelectric power is a clean, renewable source of …show more content…
Mainly, impoundment hydropower, the creation of large reservoirs, covers all of these gains. The construction of dams has many perks to society. The opportunity for many outdoor sports and activities presents itself. For example, reservoir lakes bring boating, swimming, fishing, and more. Impoundment hydropower also allows for greater control over potential emergencies, like floods and water shortages (dams can be closed to save water). In rural areas, basins provide ready-access water for farmers to use for irrigation of crops. The pros of hydropower go far beyond climate
Global climate change and its apparent effects have been the subject of much discussion for a number of years. It is often claimed that this change is too advanced and the damage caused by it is irreversible, meaning that any efforts by us to undo this are in vain. Although I agree that our planet has become unalterably changed, I don’t entirely concur that this change is now completely beyond repair.
The world in which we live in at the moment has become poisonous. It has been poisoned by the human species’ daily survival activities. Humans around the world have taken for granted the daily impact that we have on the natural world. It all boil down to each and every breath that we take. Each and every breath that we exhale releases poisonous chemicals into the atmosphere. Until when our existence becomes absent, the world will remain poisoned.
For many years we have been hearing about how the world was going to end if we do not clean up our acts and stop causing global warming. In reality, we actually are not harming the planet at all and it is all a hoax in order to help the government raise more money. They say with in an increase in CO2 and the earth’s temperature escalating we are doomed for the world to eventually go down in flames. On the contrary, the multiple unscholarly reports have been used as scare tactics when we actually have little to nothing to worry about.
The first type of renewable energy is hydroelectric energy or well known as hydropower. In greek word, hydro means water and thus hydroelectric energy refers to electricity generated using flowing water at high velocity. Lutgens and Tarbuck (1992, p. 163) stated that “running water is of great importance to people as we depend upon rivers for energy, travel and irrigation”. Continuous availability of water in universe made water to be the main source of hydroelectric energy. Water has been widely utilized by mankind since the beginning of civilization and wate...
Climate change. The two letter word so feared by scientists, so ignored by the average human being. What is it that makes scientists fear this phrase so much? For the concept of “climate change” has been seen throughout the history of the earths existence. For centuries, our climate has fluctuated through increasing and decreasing amounts of atmospheric carbon dioxide and climatic cycles. So what is the big deal? The problem, and the reason why this concept instills fear directly into the core of scientists is the rate at which over the past 1,300 years atmospheric carbon dioxide levels have risen. This unnatural increase in atmospheric carbon dioxide, due to the immense amount of anthropogenic burning of oil and coal, affects the transfer
Climate change is a long-term change in regional or global climate patterns. From the mid twentieth century to now, it has mostly been about a significant increase in average global temperatures. Climate change is a major issue in the world today, and a lot of people feel very differently about the cause of it. The common argument about it is whether climate change is a natural occurrence or if the recent increase in temperatures is because of humans. Climate change is a natural cycle in the Earth’s weather. Before humans started burning fossil fuels, there were still weather cycles on Earth that were as hot or hotter than what it is now. In fact, Earth’s weather now, is on pace with the previous weather patterns in history. Human emitted
Hydropower, the use of water to power machinery or produce electricity, provides the most renewable energy in the United States, and uses alternating current in most modern plants ("Hydropower…”). Hydropower relies on the water cycle and is a clean fuel source; it doesn’t pollute the environment like plants that burn fossil fuels. It is by far the most efficient way to generate electricity, being half the cost of using nuclear power, two-fifths the cost of using fossil fuels, and a quarter the cost of using natural gas ("Wind and Water…”). Also, hydropower is not subject to market fluctuations of embargos, and the average lifespan of a facility is 100 years. Hydropower also has many non-energy benefits such as water supply, flood control, navigation, irrigation, and recreation. However, it does face many environmental challenges such as impacts to aquatic habitats, aesthetic alterations of landscapes, changes to water quality, and interruptions of marine life ("Hydropower…”).
My parents grew up in small town in Mexico. There was a little river that went through part of the town when they were growing up. Every weekend or so they would go out and would go swimming with their families, it almost became a tradition to go swimming there until they noticed that the river 's water level was becoming smaller and smaller. Today there is no river anymore, instead it 's a road that travels through the town. Every time I visit my family in Mexico it would alway be nice and warm up until this year when I went in December. I remember waking up and getting ready to go to my aunt 's house in clothes for warm weather. As I open the door, the cold air punch me and I saw snowflakes falling down. It 's not supposed to snow in that
The Earth is currently locked in perpetuating spiral of climate change. While the global climate has unarguably been changing since the dawn of it's manifestation, the once steadied ebb and flow of climate change has become increasingly more unpredictable.The risk of rising sea levels, and drought plaguing the fresh water supply, during the time that flooding and sporadic storm conditions turn once fully inhabited regions into uninhabitable death traps. Climate change catalyzed by human's increased production of carbon dioxide, is more noticeable than ever in our recorded history (United States, 2014 National Climate Assessment). Thankfully however, with the changing weather conditions due to carbon related emissions, the change in public opinion about their personalized influence on climate change is also increasing. Kevin Liptak Jethro Mullen, and Tom Cohen note that In reaction to the most recent governmental report on climate change, even the U.S. government believes that a stronger approach needs to be taken to correct our self-generated cataclysm.
Hydropower is taking the energy out of water flowing from a higher elevation to a lower one and converting it into electricity. Hydropower has been used as source for electricity for many years and is the leading renewable energy resource in America today. Hydropower is the most dependable and effective of all renewable power sources. “And today, about seven percent of all electricity is generated from hydropower” (DOE.org) The Tennessee Valley Authority is the nation’s largest federal, public power company. TVA also has fossil fuel, nuclear, and hydropower plants. “TVA maintains 29 conventional hydroelectric dams throughout the Tennessee River System and one pumped-storage facility for the production of electricity.” (tva.gov) “Together these plants produced about 13.9 million megawatt hours of electricity in 2004, enough electricity to power nearly one million homes for a year.” (tvakids.com)
In the modern era, climate change is a variation of weather over a long period of time, and it is the most important and controversial global issue. It is arguable in different positions, especially on science, culture, and politics. These three fields all cause a lot of latent concerns. The science of climate change brings out several harmful phenomenon, such as global warming. With respect to the climate change, the culture of humanity may be changed because the changing climate is the most important key factor of forming today’s human societies. Instead, climate change is now a political issue, which will affect the public attitudes directly. In other words, it means the government tends to review and provide latest information in order to adapt and retard the climate change. Over a long period of time, climate change has been taking place because of human activities that affect the scientific, cultural, and political sides.
One efficient way to acquire energy is Hydropower. Hydropower is power derived from the energy of falling water or fast running water. This energy converter is harmless to the environment. Other ways will affect the atmosphere and the environment in a negative way. The most common device for hydropower is a dam. It relies on the water cycle. This is one of the oldest sources of energy.
Hydroelectricity is a renewable source that can be used for years and cam be expanded in many different ways. It also can produce energy from running water without reducing its quantity and can be utilized with other renewable sources that promote energy. Hydroelectricity contributes to the storing of drinking water by collecting rain water, which can then be used for irrigation; however it can also improve the air you breathe because it doesn’t release any toxins or pollutants. For a century, hydroelectricity has made long term improvements environmentally and can continue to do so for many years to come because of how affordable this technology is. (Lamb)
Our planet is suffering from severe pollution, which ranges from contaminated air, water and soil as well. Humans are doing nothing to reduce the amount of pollution that is harming our earth. To understand how pollution works first you must understand that there are different types of pollution. The most common types of pollution and the ones that I will be focusing on which are the ones doing the most harm to our planet are air pollution, water pollution, soil contamination and littering. In order to help out and reduce pollution in our planet people need to be more aware of what these problems are and about the severe damages that they are causing our planet. Before industrialization really jumped into place and had an effect on large cities, nature had its own way of cleaning up its own air and itself. Wind scattered gases, rain washed many substances and the rest dissolved into the ground; while plants absorbed carbon dioxide and made it into oxygen. With big cities growing more every time and with more towns that were becoming more industrialized a lot of more waste began to be released into the environment and the atmosphere and soon this was more than enough for nature to handle. In order to stop and reduce pollution people need to understand the damage that it is causing our environment and our planet as well. People need to be more aware of how they can help out and do their part in reducing these problems that are causing our planet to die slowly with people not even noticing it.
