73 million, average salary is around 50k in total compensation, works out to 1,460. For the amount of money lost on this vanity project you could have hired the working age population of a village to spend a year planting trees, with paid vacation, 401k matching of about 3% and 80% of health insurance coverage. Still leaving enough left over for weekly Pizza instead of pay raise parties.
I found a reference online claiming that by handtools a human can plant between 800 to 2000 trees a day. I am going to assume they all are bad at their job and can only plant 500 a day. At the end of the year 73,000 trees would been planted. The Pacific Northwest forest has 40,000 trees per square km so our planters could reforest 1.825 square km.
Glad we have our priorities correct as a civilization
