Lesson 65: The Importance of Trees (Level 2+)

Trees are vital. As the biggest plants on the planet, they give us oxygen and absorb carbon dioxide. Each year a mature tree produces enough oxygen for ten people. Trees also help prevent flooding and soil erosion by absorbing thousands of litres of rainwater. They provide a home to many birds and animals. Many types of fruits and nuts come from trees- including apples, mangoes, papayas, and almonds.

Trees provide us with wood for building and pulp for making paper.

Trees reduce wind speeds.  It is estimated that trees can reduce the temperature in a city by up to 7 degrees Celsius.

Trees improve air quality by acting as natural air filters.  They remove dust, smoke and fumes from the atmosphere by trapping them on their leaves, branches and trunks. Each individual tree removes up to 1.7 kilos of pollutants every year. They also provide shade from solar radiation and reduce noise.

Many trees have medicinal properties. Almost every part of the neem tree can be used. Neem leaves repel insects. They can also be eaten when tender. The twigs make excellent toothbrushes. Neem oil extracted from neem seeds is rich in medicinal properties and is used in soaps, hair oil and cosmetics.

Research shows that within minutes of being surrounded by trees and green space, your blood pressure drops, your heart rate slows and your stress levels come down.
