President Higgins urges BT Young Scientists to use talents to realise 'a sustainable, just world'

President Michael D Higgins delivered a rousing call to action, asking Irish school children to tackle climate change and create a better world.

"If we are to achieve that transformation that is now urgent, we need the involvement of young citizens to remain curious, constantly seeking solutions to questions they insist on keeping open," he said at the opening of 55th BT Young Scientist & Technology Exhibition in Dublin's RDS.
