Biofuels Environmental Sciences Essay Nowadays, as the problem of greenhouse gases emissions is getting more serious, Carbon-negative biofuels represent the first potentially huge assault on the problem, in ways that are already technically feasible and practicable (Mathews, 2008). Scientists are having their research on how to ease or solve these problems. The topic of biofuels is being more popular in the recent years because it has the most potential to be a significant source of energy. Biomass

Climate Change is a Natural Cycle: Global Warming is a Hype Terra Nova is a new American TV series on the Fox network, which airs on Mondays and has caught the attention of a wide audience for its science fiction suspense. The show is intriguing because it relates to a huge debate going on right now amongst scientist, politicians and environmentalist; Global Warming. Is it real and if so, are humans the cause. In Terra Nova it is year 2149 and Earth is being destroyed to extinction due to air

any contamination of the atmosphere that disturbs the natural composition and chemistry of the air. This can be in the form of particulate matter such as dust or excessive gases like carbon dioxide or other vapours that cannot be effectively removed through natural cycles, such as the carbon cycle or the nitrogen cycle. Next is water pollution. Water pollution involves any contaminated water, whether from chemical, particulate, or bacterial matter that degrades the water's quality and purity

acid molecules. The fatty acids each break down into 2 carbon parts. Each part of the carbon makes Acetyl CoA. The Acetyl CoA molecule then enters the Citric Acid Cycle before it moves on to the next step, the electron transport chain. The end result of each of these steps is the production of 12 ATP (Hudon-Miller, 2012). B. 1. Saturated fats do not contain a carbon-carbon double bond. Unsaturated fats contain at least on carbon-carbon double bond. The saturated fatty acid chains can stack

environmental advantages. Plant needed to generate biomass feedstock removes atmospheric carbon dioxide, which offsets the increase in atmospheric carbon dioxide that results from biomass fuel combustion. At present,there is no researched commercially viable way to offset the carbon dioxide added to the atmosphere (with the resultant greenhouse effect) due to fossil fuel combustion. The climate change effects of carbon dioxide from fossil fuels are now generally and globally recognized as a potential serious
