Contemporary societies are faced by a new spectre haunting the 'globe' – the changing of the world's climate. Such change is believed to be caused by increased levels of ‘greenhouse gases’ (GHGs) in the atmosphere which cannot be fully absorbed into the oceans and hence impact upon the earth’s present and future temperatures. Such a climate forcing mainly results from systems that involve extra...
In the US, there are more than 163 million dogs and cats that consume, as a significant portion of their diet, animal products and therefore potentially constitute a considerable dietary footprint. Here, the energy and animal-derived product consumption of these pets in the US is evaluated for the first time, as are the environmental impacts from the animal products fed to them, including feces...
The energy demand is sharply increasing due to industrialization, huge population growth, and increased comfort lives etc. This energy demand mostly extracts from the fossil fuels which is non-renewable and the known reservoirs expected to finish in near future. The whole world may face energy crisis soon, altogether the fossil fuel produces greenhouse gasses (GHG) which cause the climate chang...
GreenHouse Gasses’ (GHG) emission control is the greatest environmental challenge facing the world. The energy sector accounts for the highest percentage of environmental pollution. Emissions from internal combustion power generators are high and these emissions are responsible for the fast depletion of the ozone layer. Though there are other measures put in place to control the emission from p...
Carbon dioxide increase is attributed mainly combustion of fossil fuel and deforestation worldwide.1,2 The current atmospheric carbon concentration is 397.60 ppm.3 The CO2 concentration and other greenhouse gases (GHGs) in the atmosphere have increased considerably and are set to rise further. Two major environmental issues of the world today’s are climate change and biodiversity. Increase in a...
a r t i c l e i n f o This study assesses the motivation, willingness, and technical as well as managerial capacities of U.S. cities to store carbon and sell carbon offsets. Based on a national survey of urban foresters, arborists, and other officials responsible for urban forest management within U.S. municipal governments, results indicate that local governments are interested in selling carb...
