Re: Do you think there are too many people in the world? What should we do about
It is impossible to project 50 years into the future and accurately predict what the world population will be, it could less than double, just as likely as more than double, and the difference could be more than a billion. The number and size of the variables is astounding when trying to calculate future population. It has been shown that as people rise above poverty level their population growth lowers, (the rich have fewer babies than the poor). So if we continue to feed the poor they will continue to have more than one child per adult, but if we teach them capitalism they will feed themselves generate personal wealth and begin to feed others as well. Then they will be producing more than they consume and they will be too busy and too educated to contribute to a population explosion. On the other hand Islam may succeed in stopping the spread of capitalism and the world would be awash with men with several wives and dozens of children. The only way to feed the world is to teach the world to work together through capitalism and free trade.

A study on flies may hold the key to future addiction treatments.
- A new study suggests that drinking alcohol can affect how memories are stored away as good or bad.
- This may have drastic implications for how addiction is caused and how people recall intoxication.
- The findings may one day lead to a new form of treatment for those suffering from addiction.
A glass of juice has as much sugar, ounce for ounce, as a full-calorie soda. And those vitamins do almost nothing.
Quick: think back to childhood (if you've reached the scary clown you've gone too far). What did your parents or guardians give you to keep you quiet? If you're anything like most parents, it was juice. But here's the thing: juice is bad for you.
As the world gets hotter, men may have fewer and fewer viable sperm
- New research on beetles shows that successive exposure to heatwaves reduces male fertility, sometimes to the point of sterility.
- The research has implications both for how the insect population will sustain itself as well as how human fertility may work on an increasingly hotter Earth.
- With this and other evidence, it is becoming clear that more common and more extreme heatwaves may be the most dangerous aspect of climate change.
