Interior Cabinet Secretary Kithure Kindiki on Friday joined residents of Saku in Mesabit, to mark the national tree planting day.
During the exercise, the CS said climate change has become a national security threat.
"We consider climate change and its devastating effects as a national security threat," Kindiki said.
"We must reclaim our environment by growing enough trees for ecological sustainability."
He was accompanied by PS Correctional Services Salome Muhia-Beacco, Principal Administrative Secretary, NPS Bernice Sialal, National Administrative Secretary Beverly Opwora and Eastern Regional Security Team led by Regional Commissioner Paul Rotich.
The government's ambitious goal is to cultivate 15 billion trees in 10 years.
Today's exercise is Kenya’s second National Tree Growing Day, following the inaugural ‘Green Holiday’ on November 13, 2023.
