LED lights are extremely directional, to the point it can be difficult getting them to diffuse like an incandescent bulb. Most streetlights (and now, lights in sports stadiums, parking lots and the like) are extremely directional, pointing straight down and having abrupt drop-off in illumination around the periphery. In fact, in my town, streetlights that are being replaced with LED are not as good because they don't cover as large of an area or fade out on the edges in a more natural way. They almost look light spotlights shining straight down - objects are either in the light or not at all.
So I guess the light pollution from LEDs is due to light reflecting off the ground? I'm just surprised LEDs haven't decreased light pollution because of how directional they are. They should definitely be decreasing light pollution outside of the visible spectrum, because that was always an issue with the various kinds of lights used in the past for lighting large outdoor areas. A big part of their inefficiency was generating unwanted infrared or ultraviolet as a by-product.
As far as I'm concerned kids are the most important people and we're just keeping the seats warm for them.
I always hear statements like this thrown around in various contexts, and while on the surface it sounds admirable, it's really not accurate at all.
The most important people on the planet are those with the knowledge, skills and the actual power and means to accomplish what needs to be done. Without the core set of human adults that actually feed our population, keep it safe, fix broken and unhealthy bodies and the like, there would be no children. Or if there were children they would mostly be dying.
Also based on that logic, the instant a "child" becomes an adult sitting in that seat you kept warm for them, they're not important anymore, and the real focus is immediately on people younger than them. Unless there's like a grace period of importance - say you get 5 years of still being most important after you're no longer a child? See what I mean?
Obviously we need children, and we want the human race to continue and all that, and to provide for them a planet better than the one we started with and with more opportunities, but saying kids are the most important people sounds good in a Whitney Houston song, but isn't very realistic.
100% of Americans want the time changes to go away. The problem? 50% think DST should become the permanent time, while the other 50% think it should be non-DST. That's the real problem.
Personally, I'd rather have the extra hour of daylight in the evening. If it's dark in the morning then schools can start an hour later (which some in my region actually did for a week last year).
Either way, if it ever goes permanent, you're going to have half the population unhappy with what became permanent.
