For example, at a distance of 300 metres (980 ft) the sound generated may be around 45 dB; however, at a distance of 1.5 km (1 mi), most wind turbines become inaudible. [176] [177] Thus the noise generated by wind turbines does not affect human health when the turbines are properly placed. [178] [179] [180]
The Intrepid Wind Farm, in Iowa, is an example of one wind farm where the environmental impact of the project has been minimized through consultation and co-operation: "Making sure the wind farm made as gentle an environmental impact as possible was an important consideration.
An example is zinc oxide, a common paint pigment, which is extremely toxic to aquatic life. [citation needed] Toxicity or other hazards do not imply an environmental hazard, because elimination by sunlight , water or organisms (biological elimination) neutralizes many reactive or poisonous substances. Persistence towards these elimination ...
The windmills at Kinderdijk in the village of Kinderdijk, Netherlands is a UNESCO World Heritage Site. A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, by tradition specifically to mill grain (), but in some parts of the English-speaking world, the term has also been extended to encompass windpumps, wind turbines, and other applications.
Wind turbines have been used for household electric power generation in conjunction with battery storage over many decades in remote areas. [105] Examples of small-scale wind power projects in an urban setting can be found in New York City, where, since 2009, several building projects have capped their roofs with Gorlov-type helical wind turbines.
Therefore, wind is caused by the rotation of windmills. (Or, simply put: windmills, as their name indicates, are machines used to produce wind.) In this example, the correlation (simultaneity) between windmill activity and wind velocity does not imply that wind is caused by windmills.
One example I sometimes mention is the Wittgensteins. Three of Ludwig Wittgenstein’s four brothers killed themselves, and Wittgenstein himself often reported the desire. The Wittgensteins were brilliant, hugely wealthy, important members of Viennese society: people who, superficially speaking, ought to have had every reason to live.
Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Some scholars believe that the projected peak global population of roughly 9-10 billion people could live sustainably within the earth's ecosystems if humans worked to live sustainably within planetary boundaries.
