People have always been troubled by waste management concerns, thus safety health jobs have been developed. When much of the waste was agricultural material, individuals disposed of waste in abandoned pits or they burned it on their own property because there were not many people in the area. When people started to reside in urban areas, the problems of disposing wastes of daily life became serious. The great amount of waste in urban areas was so great that its disposal seemed impossible. Hence, as the situation became a problem the awareness to find its solution became prevalent in order to avoid the widespread diseases to the global population.
Since the Industrial Revolution environmental health employment has increased in its demand. Health problems brought on by smoke, noise and other product output from industries became dangerous. By the nineteenth century areas with high-population density located nearby polluting factories had caused an increasing percentage of death as well as contaminating pollutants that carried diseases. Industrialized places often suffer a distorted change of their surroundings and natural environment. The water and the air are never the same again. Odorous smell and toxic colored-rivers are common scenes which derived from the polluting companies and industrial operations. In the 1970s people began to recognize the dangers posed by hazardous waste and toxic chemicals. Until that time most hazardous wastes were simply dumped in landfills across the country. As awareness began to be raised that these landfills were polluting underground water supplies, farmland, and other ecological damage a movement began to safeguard against hazardous waste contamination and safety health jobs were maximized.
Within environmental health and safety jobs waste management industry is a highly diversified industry with processes designed to handle solid wastes, waste water (sewage), air contaminants, and hazardous wastes. As a result of the decrease in landfill space and the increase in the cost of pollution-control features metropolises are looking for ways to reduce their dependence on landfills. This has led to the development of integrated solid-waste management systems, which include conservation programs to reduce waste with recycling programs to reuse waste. One reason that conservation and recycling techniques are so effective on the solid waste control is that percentage of it is paper and other easily reusable materials.
In safety health jobs careers opportunities in waste management industries are divided between positions that required a college degree and those that do not. For instance, an environmental engineer must possess at least a Bachelor of Science degree in engineering, while water and waste water treatment plant operators just need extensive on-the-job training. Waste management is now a multi-billion dollar industry that is estimated to grow even more.
