[Time Travel] I live in a "Branching Timeline" universe. Can I create an infinite energy source by continuously harvesting resources from the past and bringing them back to the present?

I know that each travel back creates a new branching reality that does not affect my present, though i can still seamlessly return to the present. Whats to stop me harvesting past resources and bringing them forward? As far as I can tell, I can keep making new universes to mine since the energy required to travel back is far less than the big bang.I can easily go to before life evolves to get around any ethics issues.

That is actually very unethical.  
Except for that, i see no reason why you couldn't do that infinitely.  
The only way i can see this f you in the a is, when a future version of you comes to your unirverse and steals all your resources.
