None of these things: population, services, energy or carbon output are any of Bill Gates' business nor are they within the realm of his power.
Ecclesiastes 1
4 One generation passeth away, and another generation cometh: but the earth abideth for ever.
5 The sun also ariseth, and the sun goeth down, and hasteth to his place where he arose.
6 The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to his circuits.
7 All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again.
8 All things are full of labour; man cannot utter it: the eye is not satisfied with seeing, nor the ear filled with hearing.
9 The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun.
Amen friend!
