Imagine your water filter not just cleaning your water, but also slashing planet-warming methane emissions by 50%! That’s what a PhD student in the Netherlands just pulled off by tweaking how bacteria work in sand filters. Instead of letting methane escape, his new system lets bacteria munch it up, making the process way greener. This could mean cleaner water and a healthier planet—especially for places struggling with safe drinking water. Wild how a simple switch can make such a huge difference! #Science #WaterInnovation #ClimateAction
