An energy crisis is any great bottleneck) (or price rise) in the supply of energy resources to an economy. In popular literature though‚ it often refers to one of the energy sources used at a certain time and place. Causes Market failure is possible when monopoly manipulation of markets occurs. A crisis can develop due to industrial actions like union organized strikes and government embargoes. The cause may be over-consumption‚ aging infrastructure‚ choke point disruption or bottlenecks at

In the 8 million tons of industrial waste‚ the materials contained large amounts of acid based materials‚ metals‚ and waste from coal mining. Another cause is radioactive waste from medical use‚ nuclear power processes and research by using radioisotopes. Since radioisotopes are radioactive for an increasingly large amount of time‚ the waste can be extremely fatal to marine animals

The increasing reliance on fossil carbons began in the Industrial Revolution‚ but when scientists at the International Geosphere-Biosphere Programme (IGBP) undertook the detailed work of quantifying the changes in the Earth System that define the Anthropocene‚ they discovered an unexpected pattern.

Vincent Rafael P. Violago 1BSBA2 ACADEMIC READINGS The Triune Brain The first of our three brains to evolve is what scientists call the reptilian cortex. This brain sustains the elementary activities of animal survival such as respiration‚ adequate rest and a beating heart. We are not required to consciously “think” about these activities. The reptilian cortex also houses the “startle centre”‚ a mechanism that facilitates swift reactions to unexpected occurrences in our surroundings. That panicked

On the local level‚ there is erosion of soils (and the loss of vegetation)‚ the depletion of water supply‚ and intoxicating of the air and water. The earth is dynamic though‚ all of these aspects are interrelated‚ and no one impact is completely isolated. All of these destructive elements can be traced to our enormous population. As

ENERGY RESOURCES Energy is defined as ‘the capacity to do work’. Sun is the primary source of energy. Joule is the standard unit of energy in SI units. Energy utilization is an index of economic development‚ which does not take into account of ill effects/damage on to environment. From 1900 to 2000 population increased by 3 times while energy consumption by 14 times! Energy Resources All energy sources ultimately come from the sun‚ the moon or the earth.

and technological development. The pace of development after industrial revolution is unprecedented. Just 200 years ago‚ the world experienced energy revolution that launched the industrial age. The catalyst to this epochal change was ordinary black coal - an energy rich hydrocarbon. A century later‚ oil and gas were added to satiate the thirst of industry. Man still relies mainly on these fossil fuels. Nevertheless many other sources of energy: hydro‚ solar‚ nuclear‚ wind‚ geothermal‚ biogas and

Forests are cut down to accommodate human occupancy. When there is a high demand for lumber‚ buildings‚ and roads there is a need for infrastructure. In the 21st century we are more connected than ever. Agriculture is another big contributor to land depletion because the demand for crops. Poor practices of farming have also contributed to the unnecessary loss of land because of companies stimulating the world economies for profit. When companies are trying to make a quick buck they will cut through a
