Petroleum is naturally occurring liquid oil normally found in deposits beneath the surface of the earth. Through refinement processes, a variety of consumer products can be made from petroleum. Most of these are fuels: gasoline, jet fuel, diesel fuel, kerosene, and propane are common examples. It is also used to make asphalt and lubricant grease, and it is a raw material for synthetic chemicals. Chemicals and materials derived from petroleum products include plastics, pesticides, fertilizers,...
Biodiversity is any range of different species of plants and animals that surrounds our planet earth. Ecosystems help us lead a healthy life and give us oxygen of its trees, plants for our feeding those plants vegetative. It is therefore very important to take care of our ecosystem because they are essential to our life and development. Day after day our ecosystems are disappearing, pollution of rivers, deforestation and all these damages done by ourselves, humans. In the last decade there...
With the rise in temperature and our country continues to warm, dry areas of land that are already susceptible to wildfires are likely to be ravaged by even more frequent and destructive episodes. Importantly, the carbon dioxide and dangerous other gases released by these large-scale fires together with the deforestation they cause further compounds the problem of air pollution. Also the gases that help to create the greenhouse effect are supplemented and less mature trees survive to draw CO2...
Nanotechnology is an emerging science that has shown promise in humanizing various life facets ranging from medicine to industrial materials. One such application of nanotechnology is for the remediation of contaminated groundwater. Groundwater pollution is becoming a major problem not only for the developing countries like India but also for most of the developed countries of the world. In this respect the application of nanotechnology may prove a boon to the mankind by providing an advance...
By 2030 the world energy needs are predicated to be between 30 and 60 per cent higher than current levels, but of course depending upon the efficiency measures implemented. The International Energy Agency (IEA) estimates that around 4,800 GW of new energy capacity needs to be installed before 2030. This necessitates investments of a mind-boggling US$ 4 trillion.Data indicates 50% of Europe's total energy supplies are imported, much of it from regions considered volatile. Air pollution due to...
Environmental Impact Assessment (EIA) began in the United States of America in 1969 under the National Environmental Policy Act 1969 (NEPA) (1), the UK adopted the policy soon after due to the destructive environmental problems they were experiencing at the time and Australia followed soon then after. EIA focuses on development projects which may have a significant effect on the environment, although EIA is largely focused upon the biophysical environment, best practiced EIA also addresses...
The purpose of this paper is to ascertain whether green supply chain can be achieved considering the global nature of the majority of networks. There have been few ideas, views and opinions expressed by authors, practitioners and other interest group concerning "green" due to its embryonic phase. The scope of the paper is limited to the operational activities of supply chain and its impact on the environment. In this context, green supply chain will be explained, discuss the supply...
What better way to spend a hot summer day - lolling on a li-lo in the pool, with a drink in hand, staring at the clouds? This would be impossible without water. Although over 97 percent of water on Earth is part of the world ocean and a further 2 percent is ice, neither of these is easily transformed into usable water. Less than 1 percent of the total amount of water on Earth is usable for drinking, agriculture or industry (Bartholomew 2005). We take water for granted, yet this most precious...
Comprising over 70% of the Earths surface, water is undoubtedly the most precious natural resource that exists on our planet.  Without the seemingly invaluable compound comprised of hydrogen and oxygen, life on Earth would be non-existent: it is essential for everything on our planet to grow and prosper.  Although we as humans recognize this fact, we disregard it by polluting our rivers, lakes, and oceans. Subsequently, we are slowly but surely harming our planet to the point where organismsare...
Globally, disasters are seen to have one of the most devastating effects on economic development, livelihood, agriculture, health, social and human life.Disasters are said to be sudden, accidental event that causes many deaths and injuries. A large number of disasters in the world also result in significant property damages that are commonly natural causes. These include floods, hurricanes and typhoons, earthquakes and tornadoes. Tsunamis, wildfires, volcanic eruptions and landslides are among...
