If human civilization is to continue in the long term, it will be absolutely necessary to harness the power of biology in ways that make use of biological systems (from single cells all the way up to ecosystems) to sustainably modify our environment and produce food and other goods. Reworking ecosystems to flourish even as they accelerate the weathering process (far beyond what existing biological systems can achieve) is going to be needed, just as we need to move from a mode of agriculture that works at odds with natural ecosystems to one that adjusts them to supply human needs. And such work is especially necessary in the realm of materials--if we don't learn to make what we need from the carbon, hydrogen, oxygen, and nitrogen the atmosphere supplies essentially for free (plus a dash of some other elements like phosphorus and sulfur, and trace quantities of metals) the way biology does, we will surely wreck the planet by way of overconsumption even if we do manage to mitigate climate change.
