When getting from one place to another by car involves the combustion of fossil fuels that emits gasses which are harmful to the environment. The invention of automobiles is one of the cases where the invention has had a negative impact to our environment.
One of the gasses emitted is carbon dioxide, a greenhouse gas. It absorbs and emits radiation within the thermal infrared range. Greenhouse gases greatly affect the temperature of the Earth by trapping heat. Therefore when a lot of carbon dioxide is released into the atmosphere, it means that more heat is trapped in the earth’s atmosphere, leading to global warming. Some other pollutants released from the combustion settle in water and dirt through which they can enter the food chain and

E-waste is a term used describe most types of electrical and electronic equipment that have a possibility or have already been thrown away; a waste. This includes products such as computers, smartphones, mobile phones, televisions, monitors, and many other electronic goods. E-wastes have been exponentially increasing due to the increase of production of such electronic goods. According to step-negative.org the Organisation for Economic Co-operation and Development noted that between 2000 and 2005, there has been 26% of increase in the production of such electronic goods. What caused this is the increased demand for these electronic goods du to companies reducing the prices for many electrical goods. E-waste is a special kind of waste which contains many valuable and precious materials. In fact in complex electronics like computers, a wide range of elements on the periodic table can be identified. To summarize, we can see the problems that e-waste holds, and we can understand that it is a global concern due to the amount produced and the amount disposed. Moreover, large amounts of e-waste can end up in places where it may not be able to go through the proper process of being recycled. This leads to an issue concerning the efficiency of such valuable materials and their hazardous nature towards the environment. Thus the increase in production of such goods leads an increase in e-waste, which is unethical due …show more content…
The most common energy sources we know today are oil and petroleum, natural gas, coal, hydroelectric, solar power, and nuclear energy. [Carnegie Mellon University] Oil and petroleum are not renewable resources. In the year 2000, it made up 38% of all of the what the world depleted. What caused this was the fact that it can easily be transported. But this resource is considered environmentally irresponsible because it pollutes air, water, and soil. Natural gas is also a non-renewable energy source. Similar to oil and petroleum, natural gas constituted to one-fifth of the world’s dissipation, which in fact is a large amount. What makes it so serviceable is it’s flexibility to be used in industries, transportation, and to generate power. But the drawback of this is that it produces pollutants which harm the environment. Coal by far is the cheapest source of energy. But it also a non-renewable resource. It is the primary resource for electricity therefore to create this electricity, workers are needed to obtain coal. This also creates many job opportunities. Its drawback is that it produces CO2, polluting the air, water, and soil. Hydro-electric power is renewable that can be slightly cheaper than coal but it has many issues. Although it is a clean resource and very productive in the creation of electricity and is influenced by climate and geography which
Unlike traditional gasoline vehicles, electric cars do not have any in-use emissions. This drastically reduces the emissions we emit into the earth. To put this in context, “burning 1 gallon of gasoline pushes more than 19 pounds of CO2 out of your vehicle’s tailpipe”(Kliesch). As many know, gases like CO2 are classified as greenhouse gases. These gases trap heat inside the earth which causes the phenomenon known as global warming.
Hydropower dates way back to two thousand years ago, the first culture recorded in history to find use of water other than drinking and sailing were the Greeks. They have created a water wheel as a method of using water to grind down wheat into flour. In the time of 202 B.C and 9 A.D, the Han Dynasty, water power was used to break ore and was used for paper-making. For over a thousand years no one has constructed a new use for water power. Until in 1712, Thomas Newcomen from england developed the first steam engine.
The greenhouse gases in the atmosphere absorb some of this energy, while the rest is emitted back into space, as a naturally occurring cycle that repeats daily which is needed to keep the earth 's surface warm. The green house gases that humans are adding to the atmosphere are like the steroids of the climate system. The problem is that humans are producing far too much greenhouse gases due to increased human activities that demand the use of energy, which has led to emissions and an increase in greenhouse gases. An increase in these greenhouse gases in the atmosphere means more heat is trapped in the atmosphere, and less is emitted into space, which essentially warms up the average temperature of the earth. A small increase in temperature creates major effects to our environment, which is seen in the idea of climate change.
With coal mining comes the stripping of mountains, also called mountaintop removal. This is the act of blasting and stripping miles of mountain and forest to gather enough coal for the coal plants. One form of energy that could prevent the landscape from suffering is using Hydroelectric power. Hydraulic power or Hydropower uses the energy from water when the H2o moves the turbines to create the electric energy that is then sent to power grids and then homes or workplaces. Hydropower is made when the water being held in a reservoir is passed through turbines turning the kinetic energy of the water into mechanical energy when the water's force moves the turbines.
When all these extra gases are released, carbon dioxide stars to accumulate in the atmosphere. Climate change is a global issue because when the temperature of the Earth changes even very slightly, it can cause droughts and our crops can die. This is affecting our food supply. Also, when water levels rise even slightly, it can be very destructive for
Due to these issues, renewable resources should become our primary source of energy. First, there are many issues with the energies sources we use now, but one of the major ones is that nonrenewable resources cannot replenish fast enough to replace what is being consumed. Energies made from fossils are the most common types of nonrenewable resource. Specifically, the three main types of fossil fuels are coal, natural gas, and oil.
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.
1. Introduction: Carbon dioxide (CO2) is one of the important green house gases (GHGs) emitted in the atmosphere through various human and natural activities. The human activities include rapid industrialization and urbanization, deforestation, excessive use of fertilizers in agriculture, excessive use of fuels, papers and many other manmade resources whereas natural activities include volcano eruption, forest fires, earthquakes etc. Emission of GHGs in the atmosphere leads to global warming which is one of the primary reasons behind the atmospheric changes that affect the human life directly or indirectly. The consequences of global warming are extremely harsh seasons, untimely rains, extended summers and floods that results in human deaths, destruction of flora and fauna in addition to the huge economical losses.
In automobile an exhaust gas is emitted during a combustion process. The exhaust gas is actually a combination of many different gases such as N2, CO2, H2O and O2. Though some are harmless, there are few that are harmful and are considered major pollutants. The major pollutants are Hydrocarbons (HC), Nitrogen oxide (NOx), Carbon Monoxide (CO), Sulfur dioxide (SO2), etc. These gases can affect human health in both short and long term.
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.
All of the greenhouse gases contribute to the atmosphere trapping heat and warming the earth and warming the Earth has many effects. The earth being warmed, meaning from North Pole to South Pole, melts ice in the poles. The melting of the ice causes sea levels to rise and the effect of that is flooding and lost habitat for animals. Increase in temperature makes some of population of plant and animal species go down. Increase in temperature also affects the weather.
It is commonly known throughout human history that the energy used is burned from coal which creates biomass. During the Industrial Revolution, coal was an essential need to everyone, hence the discovery of oil as a substitute. Yet, the mass formation from the unearthing of oil causes more damage than benefits for the planet. Humanity had never seen a more compatible source in which came a higher demand for oil. As the public has urged to generate more oil, scientists theorized that fossil fuels will eventually run out, making way for a renewable energy route in the future (Mason).
The most intense greenhouse effects include water vapors, carbon dioxide, methane and nitrous oxide. Moreover, the other chemicals such as CFC also contribute to the green house effects. It should be noted that the absorbed energy from the atmosphere by the earth directly increase the surface temperature. The Earth only has the tendency to absorb and maintain 33 degree Celsius temperature, and rapid increase lead to destruction of the human life on Earth.
Arguably the most significant thing humans have done to cause climate change is the drastic increase in CO2. As a result of human activities, carbon dioxide, methane, nitrous oxide, and the halocarbons (a group of gases containing fluorine, chlorine, and bromine) build up in the atmosphere over time, as well as the natural sources of CO2, like vegetation. The concentration ofCO2 has went from 280 to more than 380 parts per million in just two hundred years. Still currently rising, the burning of fossil fuels by humans will continue to cause global warming and climate
2.1 INTRODUCTION Non-Renewable Resources are resources that have the potential to be used up due to consumption or overuse, they have production, development or replenishment rate that cannot match up with the depletion rate. In short these are resources that can be finished, output exceeds input, and they are infinite. Non-Renewable resources vary from non-renewable fossil fuels like coal, natural gas and oil, non-renewable alternative energy sources like nuclear energy and deep-earth geo-thermal energy, soil, and minerals (Botkin & Keller, 2012). These non-renewable resources range from a few years, up to thousands of years to replenish. The local as well as global challenge, is that most non-renewable resources are directly exploited by humans and their existence is widely threatened were usage
