Earth crossed 7 billion in population on the October 31st, 2011, and growing quickly. We have had a massive impact on the environment. Here is an amazing info-graphic with amazing statistics on the same!
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.
India is set to surpass China as the world's most populous by 2030.
That means a weighty impact on our planet. How weighty? Our friends at Masters Degree On-line did the mathematics 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.
Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the world, the Blue Planet, or by its Latin name, Terra.
Earth formed approximately 4.54 billion years ago, and life appeared on its surface within one billion years. Earth's biosphere then significantly altered the atmospheric and other basic physical conditions, which enabled the proliferation of organisms as well as the formation of the ozone layer, which together with Earth's magnetic field blocked harmful solar radiation, and permitted formerly ocean-confined life to move safely to land. The physical properties of the Earth, as well as its geological history and orbit, have allowed life to persist. Estimates on how much longer the planet will be able to continue to support life range from 500 million years (myr), to as long as 2.3 billion years (byr)
