The correct answer to this open question is the following.
Almost 70% of freshwater water on planet Earth is used for irrigation.
Let's have in mind that although 85% of planet Earth is water, it is salty water from the oceans. The rest is water that is considered fresh that can be used by humans. Of that percentage, 70% is used for irrigation in agriculture and the rest is for drinking purposes. That is why is so important to take care of the water because in some places is scarce.
