So Crowther and his team had to find scientists in those countries who were willing to share their tree density studies. According to the latest research, the total number of trees in the world is 3.041 trillion (that’s 3,041,000,000,000). His team collected 1,170 data points for his analysis, which is less than one-half of 1 percent of the points included in the updated estimate.
