We may be one of the last generations to see some of the Earth’s most cherished places. Here’s our list of 10 places to see before they vanish.

It is funny how now that we can recognize the damage to our world we so badly want to wrap it in bubble wrap and keep it the same. New species are happening from cause and effect. Not always visible immediately but it’s happening around us. The condor would have died out but people think if we protect it we can save it. But what if it’s death brings open a niche for its replacement. Without that hole, nature can’t try to fix it.

Scientists discover most accurate clocks in the universe
Pulsars, or stars that pulse due to rapid spinning, may be the best way to keep time in space.

I always laugh when people say “day” as if it’s a finite time and is universal. But in reality the only planet it effects is earth. Even the human biological clock is not set at exactly 24 hours, it runs based on a “circadian rhythm.” Circadian rhythm has been estimated from 25-26 hours to be (in more recent tests) 24.18 hours. If we can ever leave the surface this definition of time will not be useful without clocks. And with the biological clock being different from even the planets time scope, I’d rather use a more universal (no pun intended) clock than that to the planet’s rotational spin around the sun to decide my time.
