Burge and Hide (1997) point out the "world total rubber consumption (i.e. Natural plus synthetic rubber) has increased dramatically in the last two decades." The "most major NR producing countries are net exporters; the only major producers being (mostly) net importers are India and China." Until the first decade of the twentieth century, Brazil dominated the natural rubber market, but now it is dominated by Asia (see Fig. The world's largest natural rubber producers...
UK Government and a majority of developed nation's representatives have started paying a lot of attention towards low carbon emitting technologies. This proposal is for the production of photovoltaic cells in an economic way, to make this most abundant and clean fuel the cheapest and best option for people to use.Why should we emit less Carbon in the atmosphere, and shall we switch to the energy resources which are less carbon emitting?Are we aware of our environment in which we live? Do we...
Oil has provided much of the world's energy in the twentieth century, and it is likely to be an important part of energy mix well into the twenty-first century. Due to its high energy density, easy transportability at normal temperatures and pressures, and relatively high abundance, oil was, and still is, one of the most important sources of global energy. In 2009, Oil was responsible for a third (34.8%) of the world's total primary energy supply compared with almost half (46.1%) in 1971 (BP,...
The collection of source segregated food waste from households is becoming increasingly important: a number of countries have already implemented food waste collection schemes in order to divert these materials from landfill and minimize greenhouse gas (GHG) emissions. Various types of collection system have operated in the UK and elsewhere in Europe, however, only a limited number of studies have been carried out to assess the energy consumption and GHG emissions of these systems. A...
In this term, we first introduce two definitions of sustainable transportation, and then explain why it is important. After that, we focus on types of them. Finally, there will be case study and policy. What is sustainable transportation? Sustainable transport refers to the broad subject of transport that is or approaches being sustainable. It includes vehicles, energy, infrastructure, roads, railways, airways, waterways, canals, pipelines, and terminals. Transport operations and logistics as...
"All we are is a lot of talking Nitrogen" ~ Arthur Miller 1915-2005. While there remains to be a focus into ongoing investigation about the negative (or positive) health effects of Human induced Nitrogen, on both the environmental health as it relates to Earth processes and Nitrogen Cycle, as well as the health of its inhabitants. It's important to point out that Nitrogen is essential for many of those processes; it is crucial for any life on Earth.Human activity is responsible for...
Let us see at the first global warming, people in the northern region, especially its. But 60 years began in the 20th century, scientists remote intensive sea-level rise, food is the first recognition of the problem of intimidation. Gradually, the list and add a new project, the threat from ecosystem degradation to human health. Economic experts from the forestry and national security experts to assess the range of possible investment results. This will be regardless of the complexity of the...
Air pollution is the substances that accumulated in the atmosphere, which will endanger human health or produce other measured effects on living matter and other materials. [1]Air pollution is mainly emitted from the exhaust of motor vehicles, the combustion of fossil fuels as well as the burning process of coal and oil. As can be seen, the production of electricity generates the most of the pollution through coal burning.Generally speaking, pollutants can be in the form of solid particles or...
The Earth is both the creator of mankind and the sole rock on this universe with the proven capabilities for supporting living beings. The earth- especially in the past two centuries has seen vast developments and changes that have brought goodness and at the same time negativity too. The earth's continuous survival has been a topic of debates and discussions in lots of forums both local and internationally.Recently, an alarming batch of results from various scientific research on the condition...
Today climate change is a major problem our world is facing. There are many reasons for climate change. Due to increase in population there is increase in human need and its increases pollution. Due to increase in industrialization pollution has increased a great extent.Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. It can be a change in the average weather or a change in the distribution of weather...
