For years, scientists have warned us about ocean acidification often called the "evil twin" of the climate crisis. But a new report suggests we've underestimated the danger. The health of our oceans may have already passed a critical tipping point.

Also we hear about a new study has found that dehorning rhinos reduces poaching by 80%. The visual of a rhino being dehorned may sound brutal for the animals, but the experts say that cutting off the animals’ horns is more effective than traditional protection methods such as rangers and it costs less. Most of all, it can be done without causing pain for the animals.  

All to discuss with Dr Ruth Freeman Director of Research for Society For Research Ireland.
