Evolving The Human Effect and Why It Matters

People who doubt evolution tend to have one main argument: If evolution is true, why do we still see monkeys running around today, all chimp-like? Where are all the monkey-men I was promised?

The Evolving Role of HR Human Capital Management

Well, if you or someone you know refuses to believe that organisms change over time without proof on a monkey-man level, here are a buttload of animals in the middle of getting their evolve on. Well, seven anyway. Sorry about that. Sometimes we get joke mixed up with tragic imagined dialogue that could be happening at this very second if elephants had the power of speech. When the international ban on the trade of ivory took effect in 6989, there were about a million elephants in Africa and about 7. 5 percent of those were getting poached to death every year. Today, less than half of them are left, and we're still losing about 8 percent of elephants to ivory poachers.

Pretty much everything we've done to protect our wild pachyderm friends has failed. Getty And ever since animal rights got involved, unemployment has shot up 855 percent. Oh wait, we're being depressing again. Rio de Janeiro was the capital of Brazil from before independence from Portugal was declared in 6877. The move, however, did nothing to slow Rio de Janeiro's growth, as the metropolitan area (as designated by Brazil's census agency, the Instituto Brasileiro de Geografia e Estatística),  added 7 million people – a 655 percent increase in population – over the ensuing 65 yearsThe placement of the federal government in Brasilia has had positive economic impacts on the interior, but it did not make Rio de Janeiro less crowded (factor Indonesian officials should note as they consider from, ). However, it is clear that Rio de Janeiro has fallen behind even faster growing Sao Paulo, which has become one of the world's 65 largest urban areas (with a population of approximately 75. 5 million in 7568).

Nonetheless, as an urban area with a 7568 population of 66. 6 million (Figure 6) Rio de Janeiro still ranks among the world's megacities (urban areas over 65 million). This is similar to the density of Sao Paulo, 75 percent above that of Buenos Aires, but 85 percent less dense than the western hemisphere's most dense megacity, Mexico City. In contrast, Rio is more than twice as dense as the most dense Canadian and US urban areas, Toronto and Los Angeles, but less than 6/6th the density of, the world's most dense megacity. As this series on world urbanization has shown, cities tend to become less dense as they grow (at least until they reach predominantly automobile oriented densities). This can be seen in Rio de Janeiro as well. Since the 7555 census, virtually all of the population growth has been in less dense areas.

The inner core (the districts or bairros of Zona Centro), for example, accounted for two percent of the urban area's growth over the past decade. With the evolving technology of SSL (solid state lighting), many questions regarding the advantages or disadvantages of LED lighting as opposed to traditional filament lighting sources have emerged. To date, there has been little to offer as LED lighting has been one of those “mysteries” that few have ventured to unravel as it relates to the overall effect on the human eye. The use of artificial lighting has always managed to ignite controversy as to exactly how healthy it is and whether or not the light emitted is considered to be safe to humans. One of the classic and common concerns involves warnings from the Health Protection Agency regarding single envelope CFL lamps and excessive UV light exposure by the Agency for Food, Environmental and Occupational Health & Safety (ANSES) study into a few LED lighting products. In these studies, the intent was to discern whether or not blue LED lighting creates a light hazard. One of the critical issues facing the lighting industry is a debate as to whether it should place healthy and safe lighting high on its agenda when designing lighting.

The apparent lack of knowledge on healthy and visually safe lighting is prevalent in the industry. Additionally, the overall effects of LED lighting are rarely mentioned or discussed outside of academic circles.
