The increasing rate of climate change and depletion of natural resources are a consequence of human negligence, and it is up to us to rectify this problem. Although unsustainable packaging only has…

An essay about Environmental, economic and energetic costs and benefits of biodiesel and ethanol biofuels. By Jason Hill et al. The authors try to determine whether ethanol, produced from corn grain, and biodiesel, produced from soybeans provide benefits over the petroleum-based fuels they displace. To be a viable alternative to fossil fuels, a biofuel (ethanol or biodiesel) should provide a net energy gain, have superior environmental benefits, be economically competitive with fossil fuels and…

the transports would have to deliver not only food, but coal for heating. The bags of coal would be bulky and take up most of a plane’s space. As the airlift’s operation increased it exceeded General Smith’s capability. As a result, the duties of running the airlift were given to the Military Air Transport Service and a new commander Major General William H. Tunner. General Tunner had previously operated an aerial supply line during World War II that crossed the Himalayas, from India to China.…

As defined by the Inter-governmental Panel on Climate Change (IPCC), climate change is a change in the state of the climate that can be identified by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer; climate change may be due to…

2.0 Introduction Under the background of the global warming, the climate changes a lot in China over the past century and has the following characteristics.

research. However, there are other energies, less known and therefore less used, like biogas. Biogas is a renewable (source of) energy that belongs to the category of biofuels. It typically refers to a gas produced by the biological breakdown of organic matter in the absence…

worldwide recession and then unemployment crisis will occur. The worst thing that would happened is resource war would break out across the world, which means, this could be an origin of another world war. While becoming more fuel efficient and saving gas does help, it only prolongs the inevitable. On the other hand, It’s time for human races to invent and looking for the best alternative source of oil for us to live. With the consideration about pollution and our efficacy to gain it too.…
