30 billion trees on the ground.

                                    Each person in the planet represents more than 420 trees, 

A new estimate of 30 billion trees are present on the ground.The best estimates based on data from more than eight times the number of trees which are probably more than 400 billion was reported.This estimate of Yale University and colleagues from Thomas krawthr who lgayagya satellite images taken with a large-scale ground surveys taken together, these results.The team told the journal Nature that the new data shows that the Earth more than 420 trees each person represents.Greater number of trees in terms of the research has been broad-based.

Dr. krawthr warned that such a large number of trees does not mean that there will be no change.

    There is also much scope in this study that the number of errors between them may or ten times.

He told the BBC that a scientific program, is not so large that we have to explore new tree, not so much that we have discovered new carbon. It's not that the world is no good nor bad news that we have achieved this new number.be able to use. "To learn team trees densely forested four million locations around the world are gathering information.According to the team in the most dense northern forest trees were observed.One thing that was clear from the study of human impact on the number of trees are present. The team estimates that 15 million trees are cut each year compared with only five billion trees are planted.
