hello @madridbg,
This is a very aggressive practice with the planet, although it is possible to obtain more benefits in terms of oil production the reality is that this practice pollutes the water and scientists mention that it destabilises the different layers of the earth, recently a group of scientists protested against these practices saying that if they continue implementing this type of aggressive techniques with the planet the damage will be irreversible and that very probably the planet will suffer a climate change that will lead to the extinction of the human being.
