They exist in all studies and can affect the measurement of study variables and the relationships among these variables. Because of this, they are of primary concern in quantitative studies because they can interfere with obtaining a clear understanding of the relational or causal dynamics within these studies (Burns & Grove, 2011). Another way to think of it is they are variables that could possibly
In theory, this is easier for MEDC’s due having more advantaged technologies and more money available to spend on monitoring the ‘danger zone’ and then warning and planning for the hazard. However in some situations it isn’t the primary effects of the earthquake or eruption that have the greater impact, therefore not even MEDC’s can plan for it. For example in the 2010 Eyjafjallajokull eruption in Iceland, it was not the primary effects that caused problems, it was the ash cloud which was produced after the event. The Icelandic volcano, Ejajjallajokall, affected many people around the world, both wealthy and poor. The cloud caused problems for all over the world, which lead to most of the airspace to be closed.
It addresses hazardous substances in the work place and identifies the manufacturer or the importer of the substances as the primary source of information (including for distinguishing substances as hazardous substances). It recognises the material safety data sheet and the work place label as important health and safety information sources with the employer assuming responsibility in applying and communicating the (manufacturers or importers) information to employees in the work place. The legislation will therefore provide for more clearly defined rules for work practice, and information and responsibility where 'hazardous
A hazard can be defined as natural phenomena that produce negative effects on life. According to Dr Martin Degg at the University of Chester, a natural hazard only becomes a disaster if it threatens humans. In Degg’s model, the hazard circle includes all the physical factors while the factors that make a population vulnerable are mostly human. In other words a hazard that produces a disaster in one population may have only a limited effect on another less vulnerable population. Take for example the two earthquakes that affected Northridge and Haiti.
To what extent can preparedness and planning mitigate the effects of volcanic hazards? (40 marks) Volcanic activity happens across the surface of the globe and naturally hazards occur too. A hazard is a situation that poses a level of threat to life, health, property, or environment. It is easy to locate volcanoes, but it is very difficult to predict exactly when activity will take place, particularly a major eruption, this makes it difficult to prepare or plan for one. There is a very big difference that helps prepare for a volcanic hazard and that is whether you are in a MEDC or a LEDC.
Wisner, Blaikie and Davis (2004) argue that "disasters occur when hazards meet vulnerability,” meaning that in unpopulated areas hazards can not become disasters as there is no vulnerability (Quarantelli 1998). Without humans being involved, tsunamis are nothing but giant waves; they may modify areas of deserted land and destroy coral reefs but that does not make them disasters. Tsunamis become disasters when humans are involved; when their lives are at risk, their homes are destroyed, their livelihoods are lost etc. In addition, the economic loss caused by tsunamis could also largely effect the country as a whole. This essay will address the factors that affect the quality of human life in the 2011 Japan and 2004 South Asia tsunamis, and what made them become two of the word's biggest disasters.
Less rainfall means there is less water to enter into the facility and transport radioactive waste. On the negative side there are three things which cause me an unsteady feeling. First, the mountain is in an area where there has been volcanic activity. Because of the activity strong gases have entered into the ground which could cause explosions to be destructive. Secondly, the area has several faults running through the area where the proposed facility was to be built.
“While [hydraulic fracturing] can help provide energy for America's future, it also poses a new dangerous threat to wildlife and the environment. Toxic chemicals are used during fracking that can infiltrate and contaminate habitat, waterways, and even the drinking water that people and wildlife depend on” (1996-2013). Evidently, “some opponents of oil and natural gas production claim that fracking has serious environmental consequences. The truth is, while all development has challenges, hydraulic fracturing technology has a strong environmental track record and is employed under close supervision by state, local and federal regulators. Studies by the Environmental Protection Agency (EPA) and the Ground Water Protection Council (GWPC) have confirmed no direct link between hydraulic fracturing operations and groundwater contamination.
Contaminating these waters will not only harm the wildlife, but it will kill a source of food that is so dominant in Newfoundland, and also will harm hundreds of people’s jobs. Oil spills cause a lot of problems in our ocean and to our marine life. Everywhere you look people are trying to create a more sustainable ocean, and this is hard to do when there is so much pollution and threats to our environment all around us. We, as youth need to step up and try to make a change and help to make our province a better place. We can help thousands of animals survive by taking action against oil drilling in our
Economic long term effects are still unknown about this pesticide; therefore to use this pesticide could cause irreparable damage to the environment. Not knowing all there is to know about the long term exposure of Malathion, I can not willfully allow the environment and citizens to suffer. Taking into consideration the population that lives near and around the river and the emissions that would be released from the pesticide was a large factor in making my
