All biodiversity hotspots put together cover about how much percent of the earth's land area ?

The earth's surface has a negative surface charge density of 10^-9C.m^-2 . The potential difference of 400kV between the top of the atmosphere and the surface results (due to the low conductivity of the lower atmosphere) in a current of only 1800 A over the entire globe. If there wre no mechanism of sustaining atmospheric,electric field, how much time (roughly) would be required to neutralise earth's surface? [Radius of earth = 6.37 times 10^6m ]
