About 320 trees per square mile in continental US.
10^9 trees.
Area of continental US is 3,119,884 square miles.
10^9 / 3,119,884 = 320.5 trees per square mile.
Throw in Alaska which has an area of 665,400 square miles were at about 264 trees per square mile. Get Canada to help out -- that about halves the number.
Let's see. Plant 10,000 per day.
10^9 / (365 * 10000) = 274 years.
OK that's seems a bit unreasonable.
