Some of those responsible for changing the hydrological cycle

The actions of people in their environment have a great impact on the balance of water and energy that sustains this cycle, which is essential to control its existence on the planet, warned Alejandro Jaramillo Moreno, member of the Tropical Hydroclimatology Group of the Institute of Atmospheric Sciences and Climate Change (ICAyCC) of UNAM.

He explained that events such as urbanization, deforestation, groundwater extraction, and climate change, among others, are disturbing the natural hydrological cycle which influences the availability, distribution, and quality of this element, as well as the increased risk of floods or droughts.

The truth is that the surface water of the cities has changed its route; by extracting it from underground, the aquifers are polluted, and infections like Escherichia Coli, salmonella, Schistosoma, and even hepatitis A, which causes us to return poor quality water through this process and also affects other species.

“Like the Cutzamala System, which collects water from dams and transports it hundreds of kilometers from Mexico City, but that surface water represents only 26% of Mexico City’s water consumption, about 70% of the water that is used in Mexico City is underground. water”

The hydrological cycle is one of the most complex geophysical processes that exist, It is not entirely physical but includes biological phenomena, including evaporation that can arise from different forms: Plants carry transpiration in their biological processes and actively participate in this part, which ultimately becomes a cause of rain.

In this sense, he remembers that the amount of water on the planet is constant, but its availability, accessibility, and quality must be understood, along with most of the oceans, which are not suitable for human consumption.

“96.5% of the total water on our planet is salt water and only 2.5% is freshwater, of that 2.5% a large amount of the largest amount is found in glaciers, in ice water”
