We are fortunate to live in a geologically stable period. In 535 AD, a supervolcano blew away one island in the Philipines creating an 18-month nuclear winter world wide. However, that's small potatoes compared to what this planet has been through. We have enjoyed about 12,000 years of relative comfort after the last period of glaciation. This brief warm period is predicted to go away in another 10,000 years. The further you go back in time, the more extreme some of the events have been, including at least five mass extinctions. One of these was caused by an asteroid strike and another may have been caused by a deadly gamma-ray burst from space. Twice, the planet has frozen solid, covered in a mile or more of ice worldwide. In the very early days of planet Earth, a Mars-sized object hit the Earth scooping out enough material to create the moon.
The U.S. Supreme Court late Wednesday gave the Trump administration permission to enforce its toughest restriction yet on asylum seekers at the southern border
As a result, the government can now refuse to consider a request for asylum from anyone who failed to apply for it in another country after leaving home but before coming here. The order means, for instance, that migrants from Honduras, Guatemala, and El Salvador cannot seek asylum in the U.S. if they didn't first ask for it in Mexico.
National Geographic made a great documentary about the 9/11 attacks called "Inside 9/11 Zero Hour." I made an effort to watch this on youtube every year on September 11, just because I thought it was important to not forget.
The video I used to watch on youtube doesn't seem to be there anymore. There is still video available, but the video quality is not great.
It is a myth that the Amazon rain forest produces the world's oxygen. Whenever plants are consumed, whether that be by animals or by bacteria due to decay, it takes an equal amount of oxygen to metabolize the plants.
