Crown shyness is a phenomenon observed in some tree species, in which the crowns of fully stocked trees do not touch each other, forming a canopy with channel-like gaps.
Each year, we cut down 26 billion trees, for lumber, agriculture, mining and development projects. Every year, we plant about 15 billion trees, so that still leaves us with a huge deficit - something which is not sustainable and has to be addressed as soon as possible to avoid further problems down the road. Now, a former NASA engineer has found that drones could play a key part, and he plans to plant up to 1 billion trees a year using them.

The leading cause of the demise is thought to be rising surface temperatures which but high stress on large trees, along with water shortages.
Modern climate tracking and water flow records go back only 100 years, but to prepare for the worse, scientists and policy makers alike need to understand how the weather was like in the world many more years prior. A solution is to study the tree rings of certain tree species which bear telltale signs of water […]
