What are the effects of pollution on the environment? Why does it matter? All around the world, fossil fuels, such as oil, coal, and natural gas are burned and used to heat homes, run vehicles, power industry and manufacturing, and provide electricity. Even though fossil fuels provide many benefits to humans way of living, they also have many detrimental impacts on the environment and ecosystems, and even to humans. When these fossil fuels are burned, they release a gas called carbon dioxide into the atmosphere. These gases trap heat into the atmosphere, in a process known as the greenhouse effect, “which has been attributed to be the major cause of global warming” (“Shift to electric cars”). Global warming is the idea that because of the excessive …show more content…
A great renewable energy source would be that of the sun, which can be utilized using solar panels, which capture the energy from the sun. According to a National Geographic documentary, it would require approximately 100,000 square miles, or about 10 percent of the state of Nevada, to power the entire United States using solar energy (“Renewable Energy”). If we have the land, why shouldn’t it be used to give clean power to the United States, and used in other countries in need of energy. Solar energy is a great alternative because the sun is already providing enough energy to the earth in one hour to power the entire world for a year, so why not utilize this clean energy source (“Renewable Energy"). Another great renewable energy source would be that of wind power. One wind turbine produces enough energy to power over 700 homes (“Renewable Energy”). Wind turbines utilize the natural air currents of the Earth to spin a turbine that produces energy. Both of these renewable energies produce no additional pollutants into the atmosphere and utilize the natural energy that the Earth already
Greenhouse gases are those that absorb and emit infrared radiation in the atmosphere. The most abundant greenhouse gases in Earth 's atmosphere are: Carbon dioxide, Methane, Nitrous oxide ,Ozone ,Chlorofluorocarbons (CFCs). Human activities also contribute to climate change by the amounts of greenhouse gases, aerosols (small particles). The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas in the atmosphere.
Unfortunately, fossil fuel is the primary cause of pollution. Pollution caused by fossil fuel, causes acid rain and global warming. Global warming affects humans and animals as well with the climate changes due to the burning of fossil fuels. In contrast to fossil fuels, solar energy is
Burning fossil fuels is one of the main culprits that causes climate change because it releases gases into the atmosphere that trap in heat and create the greenhouse effect. According to Klaus S. Lackner, the director of the Center for Negative Carbon Emissions and a professor in School of Sustainable Engineering at Arizona State University,”Dumping carbon dioxide and other greenhouses gases into the air raises their concentrations in the atmosphere and causes gradual warming.” This gradual warming is causing many horrific effects
This is not true, wind turbines cannot produce as much energy as oil or natural gas. When the turbines are finished, the electricity bill will be 37 cents per megawatt. It takes 3 to power a small LED light. One wind turbine usually creates about 24,000 watts a day and with all the turbines built in the CWP, 130 of them, there will be 3,120,000 total watts produced a day. The average american uses about 262,368 and there are 6.745 million people that live in massachusetts.
Today, there is an excess of these heat-trapping gases. With more of these gases in the atmosphere, more heat from the sun is trapped, and therefore warming Earth’s surface. Greenhouse gases that occur naturally may include carbon dioxide, nitrous oxide, water vapor, and methane. For instance, the planet Venus has an atmosphere made mostly of carbon dioxide. As a result, heat from the sun is trapped in the atmosphere and making the planet really hot.
The burning of fossil fuels cause industrial fog and grey air smog. The unburned remains are released as soot or particles of carbon which contains varying amounts of contaminants, including mercury and sulfur. This implements that natural gases have ways of polluting the
By releasing this gas into the air the natural greenhouse gases increase and cause many effects to happen. Carbon dioxide is also caused by removing natural resources from the land for agriculture. When the Earth starts to warm many other things do to, the ocean will become more acidic and glaciers might partially melt. If the oceans become acidic, fish and other sea creatures will have an unlivable environment. If glaciers start to melt arctic animals that rely on the ice may start to become extinct.
These gases retain heat on earth thus increasing the temperature above average. Different gases have dissimilar abilities to trap heat. Deforestation is also another important reason for global warming. Plants release oxygen and take in carbon, thus providing us a clean and healthy environment. But by deforesting the lands, the trees would emit the carbon stored in them from hundreds of years making the air impure.
When burned they release a large number of carbon dioxide particles into the atmosphere. Humans are the leading, and basically only, cause of ocean acidity. Examples of humans burning fossil fuels in everyday life are when we drive our cars, or fly in airplanes. When any company uses power plants or factories they are also increasing the amount of carbon dioxide released into the air because their factories are burning tons of fossil fuels (Stone). These companies are often running their operations for days at a time without shutting them down.
Wind energy is mainly used to generate electricity like earlier wind mills modern wind machines used blades to collect the winds Kinetic energy. 1.1.1 Advantages 1) The blades ere connect to shaft that turn on an electric generator to produce electricity. 2) Use of wind power to produce electricity on commercial scale has become the fastest growing energy technology. 3) Wind energy is comparatively labor exhaustive and as a result creates
For many years now, it has been debated which of the new and upcoming renewable and sustainable energy sources if the best to use. Energy create from wind, is a very favourable contented in this debate as it is a very good alternative energy source. Wind energy is used all around the world. Humanity has been using wind energy for over 100 years. For example, we used to (some still do) use the wind energy to grind grain in old fashioned wind mills..
Non- fossil fuel energy has a lot of trouble producing the amount that fossil fuels can produce. This means we need to cut down on the amount of energy we use or just build a lot more production facilities. Another downside is that renewable energy relies on weather 90 percent of the time. If there isn 't rain to fill the dam the Hydro generators can 't run. If there isn 't wind for the wind turbines it wont go.
CHAPTER 1 1. INTRODUCTION The air we respire contains mixture of natural and man-made chemical, physical and biological elements that modifies ambient air quality. Among all air pollutants, the most threatening for human health include particulate matter and gaseous pollutants such as carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide (WHO). The movement of people into urban areas and the growth of industry within these areas has carried more people into contact with air pollution than any other time in recent memory.
One of the greatest issues that we face towards the environment has been an increasingly difficult problem over the last few years. Earths climate is changing at rapid paces and solutions are needed as quickly as possible to replenish natural ecosystems and cultures that depend on the environment. Climate change not only affects the animals in our ecosystem, but us humans as well. With the human population increasing every year, climate change is only getting worse. Many argue that the effects of climate change towards the environment are due to other extraneous factors, however, I myself am a strong believer that the problems such as rising sea levels, warmer temperatures and natural disasters are all due to both natural causes and human activity.
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. It is the energy which is abundant in nature. The sun is the ultimate source of energy. Almost all the energy that we use eventually comes from the Sun. The exception is the heat of radioactivity deep inside the Earth, which is ultimately responsible for processes taking place inside the Earth.
