What are the negative effects of overpopulation?
Population is growing rapidly, far outpacing the ability of our planet to support it, given current practices. Overpopulation is associated with negative environmental and economic outcomes ranging from the impacts of over-farming, deforestation, and water pollution to eutrophication and global warming.
How does immigration affect overpopulation?
Immigrants contribute to population growth because of both their own numbers and their above-average fertility. Most of those who immigrate are working-age adults, so immigrants are more likely than U.S.-born residents to be in their child-bearing years.
Can we survive without the moon?
Without the moon, a day on earth would only last six to twelve hours. There could be more than a thousand days in one year! That’s because the Earth’s rotation slows down over time thanks to the gravitational force — or pull of the moon — and without it, days would go by in a blink.

How many people have died throughout history?
