Anthropogenic vs natural Global Warming Anthropogenic is the cause of climate change which is influenced by humans. Many agree that humans are the main cause of climate change due to all the toxins that we release in to the atmosphere on a day to day basis. However it is argued that that natural global warming is also a huge factor influencing climate change. Green House effect Scientists have concluded that most of the observed climate change is due to human activity witch affects the atmosphere such as
needs of the future generations. Currently what has to be understood first is that there is a need for change. The maintenance of ecological processes, sustainable use of resources and maintenance of genetic diversity, as discussed by Middleton (2013), are the priorities to be changed
a fuel derived from biological material or the waste that living things produced. They serve as a renewable alternative to fossil fuels in the transport department , by reducing greenhouse gas emissions.(source: ec.europa.eu). The two most common types of biofuels in use today are ethanol and biodiesel. Ethanol is most commonly made by a process known as fermentation from biomass high in carbohydrates, sugars and starches. Ethanol is mostly used as a blending agent with gasoline to increase octane
and renewable; and finite and alternative energy sources (Hubbert, 1948). The major well-known sources will be unpacked and viewed in more detail, illustrating their life span, accessibility, sustainability and environmental impacts as well as contribution to mankind and the environment.

needs for imported oil to manufacture regular diesel fuel could be reduced by the significant use of biodiesel. The cost of biodiesel is most likely to remain stable than fossil fuel costs in future, as fossil fuel supplies decreases over time. As biodiesel is produced from agricultural feed stocks, it helps in improving economy in rural areas. Some minor changes are needed in refuelling structures and spare parts inventories. It is the only alternative fuel that runs in any conventional unmodified
BIOFUELS Two problems roused the world’s concern in recent years. One is energy crisis caused by the squandering of petroleum fuel. Second problem is environmental problems such as greenhouse effect, global warming, etc. To deal with such problems, renewable sources, utilization technology and bioenergy production technology have been developed. Bioethanol as one of the biofuel can be blended in different proportions in automobiles with gasoline. Biobutanol is also a new biofuel (Liu, Wang, & Zhang
