Tree planting involves transplanting seedlings or saplings to a permanent location. It is best done during rainy seasons in the Philippines. Deforestation is the clearing of forests through various means such as agriculture, livestock, and logging, which has negative environmental impacts like loss of habitat, climate change, and soil erosion. Planting trees provides benefits such as oxygen, shelter, climate control, and wood products, so it is important to plant trees now to offset deforestation and environmental problems.
