CGW4UA Unit 1_Lesson 1-5 Key Questions
What actions should be taken to reduce 2013's record high for global greenhouse gas (CO2) emissions? Greenhouse gas emissions are 58% higher than emissions in 1990. According to worldwatch.org CO2 is one of the primary greenhouse gas emissions, not the only gas emitted with significant warming effects into the climate. Measurements indicate that as of september 2013, 396.2 parts per million make up our atmospheric concentration of CO2. Scientists have suggested that in order to maintain a climate similar of which that has supported human civilization to date, the atmospheric concentration should be reduced to 350 parts per million. This world issue exists today firstly, because of an increase in cement production. Cement is an important construction ingredient in virtually all countries. In a world with expanding economies and growing population cement is a vital key to construction in cities across the globe. Secondly, this world issue exists mainly due coal related fossil fuels, as this emission makes up 43% of the global greenhouse gas emissions. Coal is a big part of modern day society for uses such as electricity generation, used in production of steel, cements and also as a fuel.
This pressing issue impacts the economy greatly through the changing weather patterns effecting agriculture, tourism, and recreation. Also, through human health as these gasses are expected to place stress to health and social support systems. This will effect culture greatly in the net few years as if we keep emitting excessive amounts of greenhouses gasses, something will need to change. We will not be able to continue living as wastefully as humans do and we will need to change our ways greatly. The political implications will have to take into consideration the fact that a vast majority of the worlds economy energy sources and manufacturing techniques that require these fossil fuels. Nations will need to come together in order to find productive and efficient solutions to this issue. Many social groups and organizations are already coming together working hard to find solutions to this excessive emission of greenhouse gasses.
There are various stakeholders affected by excessive greenhouse gas emissions. On one hand we have the alarming rate in which we are burning fossil fuels which creates pollution for towards humans, agriculture and the environment. On the other if we were to put some major limitations on these emissions, many businesses and even whole economies would crash. Many businesses and economies strongly rely on these fossil fuels for many different reasons. Many companies who are large contributors to these emissions offer opportunities and alternatives to customers to help save the environment. For example Air Canada provides an option for all customers of the air to “Travel Carbon Neutral” Where you can not only gain bonus air miles points, but you can donate money towards pojects such as forest restoration, municipal organic waste, and landfill gas recovery. If other organizations got on board with these ideas we could reduce CO2 and fossil fuel emissions greatly and this would become a much less pressing world issue.
2. United Nations Project Population Growth By up to 4 Billion By 2050.
In 2005 the United Nations recorded a world population of approximately 6.5 billion people. Today January 14th 2014, according to the Population Reference Bureau's world population clock the total population has increased to approximately 7.2 billion. In 2005 the United Nations made two predictions of the population from 2005 to 2050, one is a high growth rate another with a low growth rate. As predicted with a high growth rate by 2015 the population would increase to 7.4 billion, in 2030 8.8 billion, and in 2050 10.6 billion. Predicted with a low growth rate the population would reach in 2015 6.9 billion, in 2030 7.5 billion, and 2050 would go down to 7.4...
