What percentage of species do scientists predict we will drive to extinction by the year 2100?

50%

Life on Earth appears to be on its way to extinction because of the carbon being pumped into our atmosphere.

Biologists reported that one in five species on Earth show signs of extinction, and unless urgent action is taken to save the planet’s biosphere, scientists predict that  50% of species will be driven to extinction by the year 2100.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
