Biology/grade 10-Today’s topic-Deforestation- course book - pages 297 and 298.
Main points:-
Deforestation is the clearing of trees (usually on a large scale)
If trees are replaced by replanting it can be a sustainable practise
Generally the trees are being cleared for the land to be used in a different way (for building, grazing for cattle, planting of monocultures such as palm oil plantations etc) and therefore it is not sustainable
As the amount of the Earth’s surface covered by trees decreases, it causes increasingly negative effects on the environment.
