Article one: carbon dioxide (CO2) is the most important greenhouse gas produced by human activities, primarily through the combustion of fossil fuels. Its concentration in the earth’s atmosphere has risen by more than 30% since the Industrial Revolution. What an astonishing growth rate. Of course the resources are manifold, but can be reduced to six. First is respiration, both in land and sea it is a key component of the global carbon dioxide. Second are industries in the fuel and power and chemical sectors. Third are mobile sources. Globally, transport-related emissions of carbon dioxide are growing rapidly. Road transport dominates these emissions, though off-road, air and marine transport emissions are also significant. Forth is land-use change. Sixth is volcanism.
Air quality in the North West is improving. It has substantially reduced emissions from regulated industrial sites, but traffic is still causing air quality problems in major cities. From preston council I got some details about carbon dioxide emissions in recent years. Road traffic in the region increased by 15.8% between 1996 and 2006. There are around 3.8 million cars travelling on the North West’s road and this is causing air quality problems, particularly at peak travelling times. Total CO2 emissions in the Lancashire sub-region in 2006 were estimated at 12.2 million tones. This represented just over a fifth of the North West total of 59.5 million tones or 2.3% of the UK total.
Article two: what can we do to reduce the emission of the greenhouse gas? First we will review what the government did to protect air quality. The UK government published its strategic policy framework for air quality management in 1995 establishing national strategies and policies on air quality management in the environment Act.1995. The air quality strategy provides a framework for air quality control through air quality management and air quality standards. It requires all local authorities in England, Scotland and Wales to conduct local air quality reviews. The 2000 Strategy provided the framework for achieving further improvements in ambient air quality in the UK to 2003 and beyond. It set health-based standards for eight important air pollutants and objective to be achieved in the short to medium term.
What can people do to reduce the emissions of carbon dioxide? One-third of the global warming because of industrial gas, one-third is from the emission of vehicle, the final one-third is from the respiration and other causes. So we can see the combustion of the fossil fuel is primary resource of carbon dioxide. How to solve this problem completely, the only way is to develop new energy, minimize the use of coal and oil. Because it will have a lot of greenhouse gas emissions. In our life there have many ways to prevent the emissions of greenhouse gas. For example, plant trees; reduce solid waste, as far as possible to use clean energy. Make full use of solar, wind energy and other clean energy. Carry shopping bags by yourself when you shopping. We can do more to reduce the emissions.
Multimedia. I have a choice of two elements. I will do a slideshow that show the damage and resource of the greenhouse gas. My other idea is to make an interview with local people who has different job and also they will have different view of this question.
