Climate change, antibiotics may threaten soil

Researchers say livestock antibiotic residues can degrade microbe activity when combined with rising temperatures

Higher temperatures brought on by climate change in many regions can disrupt soil microbe effectiveness, recent research shows. A study by researchers at the Cary Institute of Ecosystem Studies in Millbrook, New York, has shown that when rising temperatures combine with antibiotic residues expelled by livestock, it degrades soil microbe efficiency, soil resilience to future […] Read more
