Earth Overshoot Day 2016

Guest Post by Environment Hamilton

Earth Overshoot DayToday is Earth Overshoot day, which means that today humanity has used up the amount of resources that the planet can reliably provide us renewably for the entire year. It moves several days earlier each year; in 2015 it happened on August 13th. The official website makes a number of suggestions for ways that you can make a difference.

The idea that we can continue to demand ever more each year from a planet that isn’t getting any bigger is more than a little nuts, so maybe it’s time to stop taking the word of economists about it.

  1. For what it’s worth, the video shows a relatively small Hamsterzilla, only slightly bigger than a building. If a hamster was really 9,000,000,000 (nine billion) tonnes, it would be the size of a cube 2 km on each side, or a sphere 2.5 km in diameter.

    Assumption: A hamster is approximately the density of water.

    1 tonne of water has a volume of 1 cubic metre (a cube 1m on each side).

    9,000,000,000 = m^3

    2,080 = m, which is just over 2 km

    A sphere has a volume of 4/3 pi times the radius cubed.

    9,000,000,000 = 4/3 pi r^3

    9,000,000,000 / (4/3 pi) = r^3

    2,148,591,731 ^ (1/3) = r

    1290 = r, so diameter is 2580 metres, or just over 2.5 km.
