Objects may fall from a variety of heights, and hurt people. The heavier the object, the stronger its force when it reaches the ground. Yes, we are talking about the Law of Gravity. Its validity applies to branches or tree trunks, and also for tiles, boards, or any sort of architectural fixture.
Another remarkable fact is that a gale or thunderstorm does not spare any object ahead, neither Nature’s nor human creation.
We want therefore state that, just for living in our planet, in a forest or in a city, we are subject to be hit by a falling object (caused by natural phenomena or not).
To keep a clean and safe environment in the cities is an honorable initiative. Nevertheless, when a hazard caused by a tree is identified, most of the times it can be resolved by pruning. Big and heavy branches may be cut without compromising the tree’s life.
The choice about what and where to plant are preventive solutions for this problem (to be adopted before it shows up). Systematic pruning is another preventive solution, to be put in practice continuously, i.e., during the growing phases of the tree.
Trees are Oxygen Producing Units (OPU) and putting them down is justified in extreme cases only. An example is when a tree is bent over a ravine and its fall is imminent. And, definitely, putting down a tree just for personal convenience is an anti-social and unacceptable attitude.
It is worth saying that the careful pruning of a tree means labor (people’s effort and costs). However, its outcome is highly compensating. Profits are: keeping the tree alive, better air quality and thermal stability.
