To what effect are humans directly affecting the earth's orbit around the sun?

For example, as we are extracting oil, gas, and coal and burning them; heating and evaporating water; felling and burning trees wouldn't those actions cause the earth to get lighter and affect its gravitational position?

The bye products of combustion remains in earth itself.So mass is not changing. example heating water the steam or vapor remains in the atmosphere.So total mass of earth is not changing .Products of combustion carbon di oxide is absorbed by trees and ocean.Water vapour come down as rain.


No appreciable change due to these activities If some hydrogen or other gases escape to space we also get meteorites to add weight..
