Two Scientific Ideas Dramatically Shift Thinking

These two discoveries blew me away. The first argues that the Black Death plague in Europe contributed to a 300 mini ice age. The theory argues that after such a huge number of people died so quickly, trees sprang up on unused farmland, lowering carbon dioxide levels.

This gives some awful sense of balance to the way global warming, cited as a possible cause of the destructiveness of recent natural disasters, has taken so many lives — some kind of tragic buffering capacity.

The second discovery also requires an adjustment in thinking. Viruses may have been part of the evolutionary origin of life. Woah. I can't describe it as well as the Discover article can. Stuff in there made me feel like we're still in the Dark Ages. But I can quote this stunning statistic:

Scientists estimate that they have discovered and documented less than 1 percent of all the living things on the planet. But for every organism in that unidentified 99 percent, at least 10 times as many unknown viruses are thought to exist—the vast majority of which are harmless to life and yet integral to it.
