The sun’s light is responsible for life on Earth. However, too much of our sun’s energy can burn our skin and increase skin cancer as we’ve all been told. In addition, excess UV is known to accelerate development of cataracts in our eyes and most likely macula degeneration as we age.
The sunlight though stimulates our bodies to produce Vitamin D which is necessary for bone health and development. With this mind, we need to strike a balance between what is harmful exposure to our sun’s rays and what is excess.
Another recent study in the U.K. connects adequate exposure to sunlight to keeping our blood pressure healthy. With this study, it becomes even more necessary to learn what balance our bodies need with regards to UV exposure.
You’ve most likely by now heard about how dolphins are caught in tuna fishing nets in large numbers. That same thing has been happening to sea turtles for decades now. It is estimated that millions of turtles have been ‘accidentaly’ caught up in these nets and die.
In Costa Rica for example, Duke University, Stanford University,San Diego State University and the International Conservation Society have performed a study in Costa Rica showing widespread harmful effects not only on turtles but mammals and birds.
Sea turtles see in the UV range of light. Now, researchers have come up
with small UV LED lights which are attached to fishing nets about 5 feet apart. Studies have shown a drop of about 40 percent in turtles caught in these nets directly as a result of these UV LED lights.
Fish do not see in the UV range so are not disturbed by these UV LED lights. Since fishing is such a big part of local economies and people do need food, environmentalist organizations like the World Wildlife Federation have instead helped with fisheries to develop solutions like these UV LED lights.
The fishing industry realizes also that turtles often destroy their nets and so are cooperating for the most part with new ways to steer turtles clear of nets.
According to the WWF, “The idea is that widely available fishing lights (LED or chemical lightsticks) can be attached to nets to create enough of a warning to alert marine turtles to a barrier.” Technology, though often part of ‘the problem’ at least sometimes offers up hope and benefits.
Electric cars have been around for since the 1830’s. Yes, that’s not a typo … over 180 years ago electric vehicles were cruising down the streets, or hay fields. Now in 2013, we are once again revisiting the electric car as energy conservation becomes more important. Formula 1 car racing is the fastest and most technical of all auto racing. Next year, the F1 organization will have Formula E .. all electric race cars.
By putting electric race cars on the track, its is hoped that public opinion and desire for electric cars will increase. Certainly electric vehicles are seen as less powerful and limiting. Tesla Automotive has risen to the occasion to also demonstrate that electric vehicles can be exciting.Hopefully, things like Tesla and F1 – Electric racing will promote change and stimulate companies to keep pursuing new innovations which ultimately may greatly change the face of our automotive energy world.
