Describe how over extracting raw materials causes global pollution
Pollution is when pollutants (usually green house gases) are released into our atmosphere and contaminate it. Green house gases are the pollutants that are commonly known for contributing to global warming.
When extracting raw materials from our earth we do more damage than we think, in order to build our desired project we must take our materials from the earth. This process is known as the extraction of raw materials In order to acquire the materials that you use for building, you must first extract them from their source. In order to do this you must either use quarries or a mine. Some of these materials will include rock, stone, brick, concrete, cement or iron. Without …show more content…
As you can carbon dioxide is a very small percentage and in 2010 it wad recorded as 0.039%, however due to the extraction of raw materials and other factors, this figure is expected to double within the next 100 years.
Things such as land cleaning, diesel engines, demolition, burning and working with toxic materials will cause pollution to the environment. All of these things are used when extracting raw materials. E.g. diesel is responsible for the emissions for Carbon Monoxide, hydrocarbons, nitrogen oxides and the most known pollutant, carbon dioxide. Dust from site can gather and travel throughout the atmosphere for a long period of time, polluting the atmosphere on its …show more content…
Once oil is in the water it immediately gets to work destroying sea life, removing the fur off life such as otters and making it practically impossible for them to survive the cold. These animals can’t maintain their natural body temperature and will eventually die of hypothermia. Again sea life can then eat stuff containing oil, this has effects on the such as adult fish growth will be limited and reduced, it will also effect their heart and respiration rates and can also cause their fins to erode and reproduction will be severely affected. Sources of water pollution on a construction site include things like diesel, oil, paints and harmful solvents and chemicals. When land is cleared, soil erosion is caused, this soil erosion leads to silt-bearing run-off and sediment pollution. Silt and soil then run into natural waterways, doing this makes them muddy (turbid) this then reduces the amount of sunlight that can be filtered into the water and results in the destruction of any surrounding aquatic life. Surface water run-offs can also carry other pollutants such as diesel and toxic chemicals such as cement. That yet again when consumed by an animal’s will result in death. These pollutants may also soak into groundwater which is a water source for humans, once they have become polluted they are much harder to clean compare to surface water. When it comes to the construction industry you will
