Anthony Martorana Purpose: To inform people of the advantages and disadvantages of fracking. For example: The resources that can be discovered by the use of fracking‚ but also the danger that it can have on a water supply. The purpose is to allow people to be as informed as possible if ever fronted with the decision of fracking Point of view: My point of view is that everyone should be informed going into this decision and that all positives and negatives should be weighed into making a decision

melting; they have trapped CO2 in them‚ and when they melt that trapped CO2 is released out into the atmosphere too. This is a chain reaction of humans being more industrialized. Some other greenhouse gases that effect the warming of Earth include methane and nitrous oxide. Before the Earth started to go through climate change; when the Earth got hot during the day it would always cool down by night enough. But with greenhouse gases they insulate the heat and they just get trapped in the Earth’s atmosphere

ESSAY ON ALTERNATIVE SOURCES OF ENERGY The law of conservation says that energy is neither created nor destroyed. When we use energy‚ it doesn’t disappear. We change it from one form of energy into another. A car engine burns gasoline‚ converting the chemical energy in gasoline into mechanical energy. Solar cells change radiant energy into electrical energy. Energy changes form‚ but the total amount of energy in the universe stays the same. Scientists at the Department of Energy think they have

In the world we live in today we are producing more and more waste and it has come to appoint where we must find the best method of disposing it. There are many methods currently being used such as incinerating our waste‚ recycling it or simply storing and piling it up‚ what we need to identify is the best method of disposing waste. One method of disposing waste is through landfills. A landfill is a site for disposing waste materials by burials. This is the oldest method of disposing waste.

causing it to occur. Firstly‚ there are many causes to global warming and they are split up into two kinds‚ man-made causes and natural causes. Natural causes are created naturally by nature. One natural cause is the release of methane gas from the Arctic and wetlands. Methane gas is a type of greenhouse gas that traps heat inside the atmosphere. Man- made causes do the most damage to earth. One of the common man made causes is pollution. One of the ways humans cause pollution is through the burning

successfully proved that organic compounds can be served substitution of fossil fuel supply. The structure and physical properties of organic molecules are characteristics that aid them to become useful fuels for human beings. Ethanol‚ propane and methane are examples of organic compounds which are commonly used as fuels today. What are the structure and physical properties of these compounds that help them to act as excellent alternative fuel sources? Figure 1 Energy-rich organic molecules (biofuels)

fields of environmental science and climatology. Global warming is the gradual‚ upward trend of global average temperatures which‚ as noted in the 1950s by scientists‚ appears to be closely related to the dramatic increase in carbon dioxide and methane emissions since the beginning of the American industrial revolution. The number of potential topics related to global warming seems almost endless‚ with many possible avenues for original thought and argument. Though the basic fact our world is

greenhouse effect‚ and so we can breathe. The leading factors for deforestation is the need for space for homes and buildings‚ and soil erosion. Another reason people think global warming is natural is permafrost. Frozen soil keeps in the carbon and methane gases. The permafrost is actually leaking carbon into the earth’s atmosphere. However‚ the use of fertilizer is also another contributing factor for global warming. The fertilizer used is it produces nitrous oxide. Nitrous Oxide is 300 times more
