According to the U.N. Population Fund, on October 31, 2011, the earth became home to 7 billion people. And the population is growing quickly. Estimates put the planet at 8 billion in another 14 years, which is an eye blink compared to the 123 years it took us to go from 1 billion to 2 billion.
That means a weighty impact on our planet. How weighty? Our friends at Masters Degree Online did the math and found that we humans account for just .00018% of the earth’s biomass, yet we use 20% of its resources.
And before you start arguing that our weight demands that kind of use, the data shows we humans collectively tip the scales at 350 million tons, while the lowly ants would crush us with their 3 billion collective tons. (Looks like exterminator might be a good career choice for some of the 7 billion of us.)
