¿Que impacto tiene los diferentes tipos de centrales eléctricas en nuestro medio ambiente?​
Fofino [41]

Answer:

Sin los correspondientes controles y marcos regulatorios, las centrales eléctricas pueden tener efectos adversos sobre el medio ambiente y contaminar los ecosistemas naturales, representando un serio riesgo para la salud humana

Explanation:

Las centrales eléctricas representan un riesgo latente para el medio ambiente, con lo cual ellas deben estar bajo un estricto marco regulatorio y control por parte de las instituciones gubernamentales especializadas para tal fin. Por ejemplo, las centrales hidroeléctricas generan la inundación permanente de grandes áreas (incluso miles de hectáreas) con el objetivo de aumentar la capacidad de generación de energía eléctrica. Por otra parte, se cree que aproximadamente el 50% de la polución industrial se debe a la acción de centrales eléctricas convencionales, las cuales utilizan la combustión del carbón, el petróleo o el gas natural con el objetivo de generar energía eléctrica. Este tipo de centrales eléctricas producen dióxido de carbono (CO2), el principal gas de efecto invernadero y considerablemente deterioran la calidad del aire que respiramos mediante la liberación de partículas contaminantes, presentando efectos adversos tanto para la salud humana como para el medio ambiente. Finalmente, la instalación de centrales eléctricas a base de la energía nuclear no generan gases causantes del efecto invernadero, pero pueden representar un serio riesgo debido a la posibilidad de liberación de materiales radiactivos durante accidentes nucleares, los cuales son capaces de contaminar permanentemente el medio ambiente. En este punto, es importante aclarar que los riesgos de accidentes en centrales nucleares se ha reducido notablemente en las últimas décadas y, por lo tanto, este tipo de centrales eléctricas se consideran relativamente seguras.

<span>Biotechnology is a set of techniques by which human beings modify living things or use them as tools. In its modern form, biotechnology uses the techniques of molecular biology to understand and manipulate the basic building blocks of living things. The earliest biotechnology, however, was the selective breeding of plants and animals to improve their food value. This was followed in time by the use of yeast to make bread, wine, and beer. These early forms of biotechnology began about ten thousand years ago and lie at the basis of human cultural evolution from small bands of hunter-gatherers to large, settled communities, cities, and nations, giving rise, in turn, to writing and other technologies. It is doubtful that, at the outset, the first biotechnological understood the effects of their actions, and so the reason for their persistence in pursuing, for example, selective breeding over the hundreds of generations necessary to show much advantage in food value, remains something of a mystery.</span>
