What will the Earth look like in 5,000 years?

Human technology has advanced significantly over the past 5,000 years, and the Earth bears the scars to prove it. We've altered the landscape, the climate and the biological diversity. We've erected skyscrapers for the living and colossal tombs for the dead. Perhaps most important, we've learned to harness a portion of the planet's energy, but we still thirst for so much more power.This insatiable appetite for energy will continue to chart the course of human civilization in the 5,000 years to come. As a result, it will also dictate what Earth will look like in A.D. 7010.In 1964, Russian astrophysicist Nicolai Kardashev theorized that a civilization's technical advancement directly correlates to the amount of energy its citizens can manipulate. Along these lines, he defined three classifications for advanced civilizations in the galaxy:

Type I civilizations are masters of planetary energy, meaning that they can harness the sum energy of an entire world.

Type II civilizations can summon the power of an entire star system.

Type III civilizations command energy on a galactic scale.
