According to the American Meteorological Society (AMS, 2007), the direct human impact on the climate change is through the enhanced concentration of trace gases such as carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor which, collectively, are known as the greenhouse gases. With the enhanced amounts of greenhouse gases in the earth’s atmosphere, the infrared radiation emitted by the earth and its atmosphere is blocked by the thickening blanket of greenhouse gases, resulting to increased warmth in the earth’s temperature in its attempt to equalize the incoming and outgoing flows of energy.
AMS (2007) further reports that Carbon dioxide (CO₂) accounts for about half of the human-induced greenhouse gas contribution to global warming since the latter part of 1800s. CO₂ concentration has been increasing mainly from fossil fuel burning and partly from clearing of vegetation. Significant part (50%) of the increased CO₂ emissions remains in the atmosphere, while the rest of the earth absorbs continually the remaining 50%. Interestingly alarming is that the atmospheric CO₂ concentration has been increasing at a much faster rate than any other observed in the past several thousand years’ geological record.
The World Wildlife Fund (WWF, 2009) reports that around 97 percent of the CO₂ emitted by the western industrialized nations is mainly coming from burning coal, oil and gas energy. The western industrialized nations spew into the atmosphere approximately 25 billion metric tons of CO₂ each year, which is enough to cause temperature build-up that seriously disrupts the world climate’s natural balance.
As the scientific community continues to understand, monitor and discover things about the environmental changes happening around the globe, it also tries to translate scientific discoveries into

Global warming especially has had a control of the worst outcomes in the world today. Global can be defined as the increase of the planet’s over the surface average temperature due to the absorption of the infra- red radiation by the atmospheric gases including carbon dioxide, methane.
For purposes of computing carbon footprint, it is pertinent to ensure that there are established boundaries of computation. This is because the computation of carbon footprint can be visualized as having a number of boundaries that are different.
Man requires the resources provided by nature but how will man know how much he is using and how much he is supposed to use for sustainable development? Ecological footprint is the answer to this question as it is a measure of man’s demand for nature and the capability of nature to regenerate what man has used, as well as to absorb the waste produced by man.
This is apparent in Europe and North America where the early environmental law has inclined to follow the traditional command and control advance. Though the kind of regulation is sometime considered as top-down, it is though based on state-centered vision basically for environmental protection.
Ehrlich, concerned with population, more specifically over-population of the earth, provides a number of imaginary fatalistic and cynical scenarios to illustrate the state of the earth, its governments, and its doom; his answer to population control is death rather than control of birth, death by self-extermination of the environment.
Unlike nitrogen which is fixed from the atmosphere, phosphorus can come only downstream to aquatic systems, not including that deposited from the atmosphere. Appropriate fertilisation plans are required for controlling diffuse
Therefore, 0.01 ppm = 0.01 volume of Ozone gas/106 volumes of air. Ppmv = (ppm/MW) × 22.4. Ppmv of ozone = 0.00467 ppmv O3. This means for every 1 million volume of air, there is 0.00467 volumes of Ozone (Dr Richards 01). Therefore, if 1 million volumes of
In order meet our daily human activities, we have to consume resources and produce waste. For our survival, Mother Nature must have the capacity to meet these demands, failure to which, the planet earth will be an unbearable place to live.
