Overpopulation: The root of the world's biggest problems?
Think about this:
- It took millions of years for humans to reach a population of 1 billion
- That milestone happened about 200 years ago
- 100 years ago, there were 1.6 billion people around
- Today there are 6.7 billion people walking the Earth
- In 50 years, there could be 9 billion
More to think about:
- 200 years ago, forests covered about 40 percent of the planet's land mass
- Today we are closing in on 20 percent coverage, losing close to 1 percent per year
And some more:
- Species loss today is about 1,000 times greater than the Earth's background level
- In 1950, no fish stocks had collapsed
- Today, 30 percent of fish stocks are unharvestable
- Before 2050, all fish stocks may be collapsed
And even more:
- In the past 100 years, sea levels have risen 4.33 inches -- for which natural process cannot account
- By 2100, that change could amount to more than 20 inches
- The world's temperature has risen 1.1 deg C (2 deg F) since 1900
- Average temperatures may climb by to 1.9 deg C (3.5 deg F)
Giving our solar system a "slap in the face."
- A stream of galactic debris is hurtling at us, pulling dark matter along with it
- It's traveling so quickly it's been described as a hurricane of dark matter
- Scientists are excited to set their particle detectors at the onslffaught
The climate change we're witnessing is more dramatic than we might think.
A lazy buzz phrase – 'Is this the new normal?' – has been doing the rounds as extreme climate events have been piling up over the past year. To which the riposte should be: it's worse than that – we're on the road to even more frequent, more extreme events than we saw this year.
Once again, our circadian rhythm points the way.
- Seven individuals were locked inside a windowless, internetless room for 37 days.
- While at rest, they burned 130 more calories at 5 p.m. than at 5 a.m.
- Morning time again shown not to be the best time to eat.
