All the cell phones used around the world in one day produce less electric impulses than a single human brain for the same period.
In Iceland, there are 210 000 cell phones in use for a population of 250 000 inhabitants.
The Nunavut Territories in Canada are about 2 million square kilometers wide; on this territory live less than 30 000 persons and more than 300 000 cariboes.

It is not uncommon that some spotted hyaenas tear out and eat some car pieces.
Hyenas can comsume prey carrying anthrax without contracting the disease itself.
Thomas Harvey, the pathologist who made Albert Einstein’s autopsy in 1955, stole Einstein’s brain and put it in a jar. He kept it in that jar for himself during 43 years (sometimes giving pieces of the brain to promising researchers), before finally giving the jar to the pathology department of the University Medical Center at Princeton in 1998 (Harvey was then 85 years old).
There have been 5 biological crisis bringing massive extinctions in the history of Earth. At the two firsts, during the primary era, 70% of all species disappeared; 90% disappeared at the third, marking the transition from the primary era to the secondary era. The fourth crisis, at the Jurassic period, was much less catastrophic. The fifth one, at passage from the secondary era to the tertiary era, has been the one where the dinosaurs and a large part of the marine vertebrates disappeared; the diversity of the insect species wasn’t affected by that massive extinction. These biological crisis were most likely caused by natural catastrophies (like meteor collisions or gigantic volcano outbursts).
