TREES are beautiful and are also absolutely crucial to our existence on earth. They absorb carbon dioxide and turn it into oxygen, which we can then breathe in.

The natural carbon dioxide cycle keeps the amount of CO2 in our atmosphere in balance. But we do things that can upset this balance. Too many greenhouse gases lead to heat being trapped in the atmosphere, which increases the average temperature, causing global warming.

The burning of coal and petrol (fossil fuels) produces too much carbon dioxide. But we can make a difference by planting more trees. - plantzafrica.com; plantdatabase.co.za; forestry.co.za
