#vegetarian #vegan #evolution Originally shared by Sean P. O. MacCath-Moran +Eve Volve: "Meat allowed us to evolve" Really? I think you're mistaken to believe this is a certainty, but what causes you to believe this is so, +Eve Volve ? As I understand it, there have been healthy, thriving vegetarians and vegans for as long as there have been humans. Some were so due to moral or ethical concerns, others due to resource utilization issues, others due to cultural taboos. All other factors being equal, the veg(etari)ans have thrived, and continue to do so. For some more recent historical examples of vegans, we can look at Pythagoras, the "Pythagoreans" (as vegans were called for the following 1300 years), along with a plethora of like-minded contemporaries (e.g. goo.gl/lgDBL ). Buddhists, Jainists, et al., have been doing grand as veg(etari)ans since around the 6th century BCE. Prior to this, there's compelling reason to believe that most people were veg...
Go 100% LED Jessica Meyer !
ReplyDeleteEnergy saving light bulbs are dangerous closer than several dozen centimerters.. So, they are OK for roof lighting, but are NOT okay for bedside lighting.
ReplyDeleteAs for LED: they are OK (more than OK http://www.ted.com/talks/harald_haas_wireless_data_from_every_light_bulb.html) as long as you take into consideration that the backside is really hot.
Several new LED 'lightbulb' designs have surfaced within the last few months, with better heat dispersion technology.
ReplyDeleteI agree with Zephram Farrington I am currently using the LED bulbs and I'm quite happy with the light color and as far as I know my skin is fine. :)
ReplyDeleteZephram Farrington and Gunther Cox Thanks! Dare to share some links? The main issue for me is not heat dispersal, it is heat creation. Any progress on this?
ReplyDeleteDavid Latapie This is the type that I am using: http://www.amazon.com/LED8E26A1930K-3000K-Dimmable-Watt-Lamp/dp/B005FG51XA
ReplyDeleteThe price makes some people back off and not buy these but the thing is that the only reason that it is higher priced is because the manufacturer has to be able to compete with other light bulb makers. If they sold them for less they wold go out of business because the LED bulbs can last for over four years! I am sitting under the light from one now and the bulb is just about skin temperature when I touch it.
Also, regular bulbs which last only a few months run at about $9.00 so it all works out to be about the same price for bulbs in the end. You just pay a lower electric bill.
I will try, David Latapie, but I am on mobile and might not be able to track them down. As I recall, the recent innovations were primarily in heat distribution/dispersal, not heat creation, but I may have missed something.
ReplyDeleteGunther Cox Thank you, but my point whas that led are cold on the frontside (the lighting side - that is why this is skin temperature), but actually hot on the backside (the part you don't see). This matters if you plan to avoid any kind of ventilation or put them close to a flamable object (like papier), I'd say.
ReplyDeleteand LEDs are hardly great either http://ceolas.net/#li15ledax
ReplyDeletedont confuse color temperature with their uneven spectral quality
The pushed white LEDs are basicaly like CFLs given their use of phosphorescent coating to spread light
Peter Dublin Thanks. Alarming.
