Even though it’s not easy to get people to change and it is not completely fail proof, green living should be introduced into the American way of life because it can make the environment cleaner and safer and save people money on electric, water, and gas. The concept of green living is based on simply carrying out acts of knowledge to keep our planet healthy. People were put on the earth to take care of it, not hurt it. Ironically, however, we are hurting it every day and in result it takes a toll on our population in negative ways. People will most likely not make a big issue about this because there are no catastrophic affects to them directly yet. The enforcement of green living happens to be very controversial and if people don’t take action soon enough it will be too late. According to the article “Renewable Energy”, “Renewable energy accounted for only 10.5 percent of all the energy produced in the United States” (Renewable Energy). Our planet relies on hundreds of thousands of different resources. Generation after generation, the human population has created potential for various studies and developments of more efficient ways to get energy that we need without harming the environment. The consumption of energy sources for simple operations like driving, heat and cooling for our house and much more is extremely high and always in demand. Renewable energy or alternative energy is energy from sources that are infinite and natural such as solar, hydrogen, wind, and hydroelectric power. Its abundance makes it easier to produce for the energy companies; therefore it makes energy bills less expensive. Solar energy is used by absorbing the suns rays and converting it into heat to bring water to a boiling point to produce... ... middle of paper ... ...Social Science Library.

Natural gas, Priuses, LEDs, hydropower, solar power, burning trash, or improving traffic is not the answer to becoming a green nation. People need to change their behavior in order to change their actions; everyone must take a stand and use cars less, use less electricity, and use less of everything, because less is enough. If we wish to discourage society from using excess energy there needs to be an increase in: prices of oil, electricity, worsened traffic, and denser city populations. There is a way to do this without having the populace revolt: increase the prices of these services or goods nevertheless offering a modest stipend for those who decrease usage. If we truly want to live on Earth for a prolonged period of time, then we need to take care of her but are we willing to change our consumer mentality for the future of our
The California water drought has been declared a crisis by the governor of California. 2013 was the driest year on record, and California could be running out of water. Californians should be water wise, and their use, or no use, of water will have an enormous impact on this drought. They can use the techniques published in a recent Time article called, 5 Ways to Bust California’s Drought, to reduce their water use. Landscape techniques, alternate water sources, and the personal conservation of water can reduce the use of water, and can have a positive change on this water crisis.
On the heart (center) of California is a flat area with miles and miles of farms and up to 230 different crops. The central valley agriculture is essential to the United States; it not only delivers almost half of the produce but also helps the economy by also giving more job opportunities (California Department of food and agriculture, 2014). Many families depend on the central valley agriculture to survive economically in the United States. It is a well-known fact that rain and snows in the Sierra Nevada Mountains are a very important element in the central valley. No rain in the central valley can cause many devastating issues to occur quickly. Recently in the year of 2013 California received less rainfall than years before. The small amount of water the central valley is receiving is harming not only to the land but humans and animals as well. It’s destroying the habitats of animals with forest fires caused from the dry spells occurring. The central valley is going through a drought, so much that around this time of year the central valley usually accumulates enough rain for the necessities in the valley, agriculture for example. This year, however, has been different, the central valley hasn’t received enough water and this has caused a drought in the valley. Water is an important element in this world for not only human life, but for the environment in general, a shortage of water supply can bring issues to the environment and those living in it. The central valley holds the largest percent of class one soil, not only that, the valley grows a third of all the produce being grown in the United States, that’s more than 230 crops that are being grown in the central valley. However, this drought isn’t only affecting the resident...
With the rapid growth of our global population pouring into the next millennium, we will witness an ever-growing hunger rate around the world. That is unless we call for a revolution on the global scale. The Green Revolution which already sprouted in the early part of the century only need to add a bit more momentum and we will see a bright future for the human race, a future without hunger and starvation ¡V hopefully.It is becoming increasingly difficult for the planet to support its overwhelming population. And since the amount of arable land available is becoming scarce, we must seek ways to dramatically improve crop yields of existing cropland.
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
According to the Union of Concerned Scientists, “Renewable energy — wind, solar, geothermal, hydroelectric, and biomass — provides substantial benefits for our climate, our health, and our economy.” One major benefit is that there would be little to no global warming emissions. Currently, electricity production accounts for about one-third of the emissions put off by the United States, mostly due to coal-fired plants. Renewable energy sources would produce little to no emissions. “According to data aggregated by the International Panel on Climate Change, life-cycle global warming emissions associated with renewable energy—including manufacturing, installation, operation and maintenance, and dismantling and decommissioning—are minimal” When comparing renewable sources to natural gas, which emits between 0.6 and 2 pounds of carbon dioxide equivalent per kilowatt-hour (CO2E/kWh), renewable sources such as wind, solar and hydro-electrical power emit somewhere between .07 and .5 (CO2E/kWh). It is obvious that renewable energy is the way to go in order to solve the energy production problem. (Benefits of Renewable Energy
Don’t you want the trash cleaned up to enjoy nature? Don’t you want the water clean for you to drink? And don’t you want to see the skies clear and blue all the time? If we don’t act now, there might not be a world to save. Go green for the sake of the future.
Review: So today, I brought to light just how serious this water drought is, what we as individuals can do to reduce the problem, and what many organizations are doing to promote awareness and find more efficient ways of using water.
Clean and safe drinking water resources are becoming scarce as the population grows. The world is facing many problems, but the most important thing needed to survive, is water. Water is getting low in many countries, therefore residents are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands.
Why do we need to rely on renewable sources? Most of the energy that we use today comes from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, so you can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy.
With the population expecting to rise 40-50% within the next 50 years, the demand for water in Agricultural needs and Environmental needs will rise as well, creating a more desperate water crisis.
By showing the world the severity of our need for conservation, we will be able to save the earth and get the most out of our resources. We need to fix this problem before it becomes uncontrollable to the point of having no resources to supply our needs. By reducing our consumption of resources, we will be able to become closer to fixing the problem of global warming, high gasoline prices and pesticide filled meats. The outcome of respecting our world and “going green” will better how we live our lives, our communities and the environment. The concept of “going green” is a necessity for the future because “our children deserve cities as beautiful as they are.
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
One fairly simple way that people can immediately contribute to the green movement is by recycling. “Recycling is the process of turning one products useful part or parts into a new product; this is done to conserve on the consumption of resources, energy and space used in landfills.” (Recycling Facts and Benefits) Most household paper, plastic, glass, aluminum, and cardboard products are recyclable. Many towns in the United States offer recycling services that will pick up your recyclables and transport them to a recycling facility. These facilities reuse the materials that the recyclables are made from and make new products. This process saves energy, and conserves resources by reducing the amount of renewable resources that would normally end up in a landfill or in an incinerator. These recycling plants “increase jobs in manufacturing while simultaneously increasing the Unite State’s competitiveness in industry.”(Recycling | Reduce, Reuse, Recycle | US EPA.)
