Planet Earth is undergoing an accelerated process of change associated with a wide range of anthropogenic phenomena. The future of these changes is uncertain, but there is general agreement that this negative development might be detrimental to our own survival. Although different environmental engineering strategies have been developed, none of them seem to address carbon dioxide accumulation, biosphere, and ecosystem safety. The rapidly increasing potential for the development of living systems through the biotechnology and bioengineering of microbes is a sustainable alternative to address safety issues.
