Is it true that there is a football field of rainforest cleared every second?
-
According to this website http://www.nature.org/ourinitiatives/urgentissues/rainforests/rainforests-facts.xml > Every second, a slice of rainforest the size of a football field is > mowed down. That's 86,400 football fields of rainforest per day, or > over 31 million football fields of rainforest each year. How can that be true? Given that a football field (without knowing which code of football, I will just assume American football) is 110m x 48.8m (http://en.wikipedia.org/wiki/American_football_field#Field_and_players) which gives it an area of about 5300 sqt metres. Which means in one year 5300 * 3100000 = 16,430,000,000 sqt metre. [about 16 million sqt kms] of rain forest is lost. Also, in the article they state... > Originally, 6 million square miles of tropical rainforest existed > worldwide. But as a result of deforestation, only 2.6 million square > miles remain. 2.6 million sqt miles = 2.6 * 1.6 = 4.16 sqt kms. Is my math wrong? Cause at this rate, wouldn't this mean that every tree in every rainforest on earth would be gone in like 3 months?

Answer:
According to Greenpeace, 1.5 acres of rain forest is cleared every second. This is the source white paper: https://www.greenpeace.org.au/secure/donate/Greenpeace_workplace_giving.pdf The area covered by a football field is approximately 1.1 acres (160 feet by 360 feet or 57600 sq feet) , so one and half football fields are cleared every second.

The error in your math is here: Which means in one year 5300 * 3100000 = 16,430,000,000 sqt metre. [about 16 million sqt kms] of rain forest is lost. 16.43 billions square meters are just 16,430 sq km and not 16,430,000 sq km. So rainforests would be gone in 3,000 months (250 years) instead of 3 months.
