Unclear statement
In "Antibiosignatures" paragraph the statement "The evidence that nothing on an earth is taking advantage of the "free lunch" available due to an observed redox imbalance is called antibiosignatures" is unclear. Please clarify & rephrase. Thanks GOLDSROBI (talk) 17:31, 2 April 2024 (UTC)
