Importance of trees
Answers
Explanation:
Trees benefit health
The canopies of trees act as a physical filter, trapping dust and absorbing pollutants from the air. Each individual tree removes up to 1.7 kilos every year. They also provide shade from solar radiation and reduce noise.
Over 20 species of British trees and shrubs are known to have medicinal properties. The oil from birch bark, for example, has antiseptic properties.
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.
Trees benefit the environment
Trees absorb carbon dioxide as they grow and the carbon that they store in their wood helps slow the rate of global warming.
They reduce wind speeds and cool the air as they lose moisture and reflect heat upwards from their leaves. It’s estimated that trees can reduce the temperature in a city by up to 7°C.
Trees also help prevent flooding and soil erosion, absorbing thousands of litres of stormwater.
Answer:
Importance of trees
We depend on trees for our survival. The oxygen of the air that we breathe to stay alive is released by trees. Trees absorb the harmful carbon dioxide and release oxygen. This reduces the level of carbon dioxide in the air and decreases the cases of lungs cancer and other diseases of the respiratory system.
Trees are home to many animals and birds. Many animals feed on tree leaves to survive. Trees offer us shade when it is hot. But despite our dependence on trees, we are continuing to cut them down. This is one of the reasons for global warming.
The roots of trees prevent soil erosion. The absence of trees leads to desertification. Trees retain rainwater in the soil. This rainwater is then available to us in springs and wells during the dry season. Without trees rainfall decreases and cultivation becomes impossible and there will be food scarcity. Many trees have medicinal values and save lives. Trees reduce air and noise pollution. Trees also add beauty to our surroundings. Let us stop felling trees and plant more trees.
