But the bacteria growth in Petri dishes is limited by resource, and bacteria has no way to change the situation. Maybe we are really limited by available resources. We know for sure that we have limited supply of the solar energy. At the other hand, we are just using what is available on the surface of the Earth. Maybe we are going to figure out how to utilize more resources outside the surface of the Earth, or efficient way to use and recycle resources.
