I have 5 apples. If I gave you 1 of them everyday, in how many days would I run out of apples?
Ok, another one - The Earth has 1.4 billion hectares of primary forest. Every year, we lose 6 million hectares. How long would it take to lose the entire forest area?
The first problem is simple because it is easily measurable and tangible in some sense. Most of us know what apples are and how 5 of them together look. But 200 years seems long enough. Or is it?
Think about it...
