Considerable attention has been paid to tropical deforestation in recent years; yet much less is said about mid-latitude deforestation. Why should tropical deforestation draw such special concern?

What will be an ideal response?


Answer: Trees in the tropics grow year-round where mid-latitude forests only have a growing season of 5-7 months. With rapid growth, these forests are able to attain 60%-75% of the growth of the plants of the tropics. However, because of the year-round growth patterns, loss of tropical forests have a greater significance on global patterns than the mid-latitude forests.
