Isang Puso, Isang Puno para sa Panginoon (translated literally as ‘One Heart, One Tree for the Lord’), a tree planting activity was held on June 23, 2023, at Mount Purro Nature Reserve (MPNR), Antipolo City. Over 100 TSPI employees participated and was made special by the presence of Dumagats. Its impact on the environment is evident: planting trees will prevent flooding and protect the environment and the people, especially those living in Metro Manila, since MPNR is situated in the Sierra Madre Mountain Range mountains.
