Rainforest Trees Make Healthy Precipitation For the Whole Planet!

Seems like no matter where you are, talk about drought is on the tip of everyone’s tongue. I was recently in California this past April and was surprised to see the all fountains, even the ones in Beverly Hills, completely turned off. Babylon is running out of water. How ironic because Babylon used to be known for its lush hanging hydroponic gardens overflowing with plenty of water and more than enough food for all. Now look at us.

Empty fountains in California reveal just how serious the water shortage situation really is!

Water wars have begun whether you know it or not. Competition for this precious resource is going to become ever more fierce because we have altered our air composition and cut down way too many trees. Excess carbon dioxide is driving up temperatures which is, in turn, trapping in more water vapor.

Deforestation means hot ground surface temperatures and NO water absorption.

Rainforests balance the global temperature and water cycles through recycling huge quantities of rainfall. Enormous amounts of water are continuously being elevated through the one-way, antigravity valving system of trees. Each canopy tree transpires some 200 gallons ( 760 liters) of water annually. For every acre of canopy rainforest, trees transpire about 20,000 gallons (76,000L) of water. [1] The tree feeds the rain-forming atmosphere by leaking atomized water out through its leaves while at the same time sucking in fresh water through its roots. Trees run the rainfall/snowfall system through their evapo-transpiration. So how do the trees recycle the rain?

Water evaporates from the sea and from the trees, first rising as water vapor and then condensing and falling as rain, a process referred to as evapo-transpiration. Some rainwater sinks into the earth and some rainwater drains away over the ground surface, depending on the temperature of the ground surface coupled with whether there are trees there or not. In forested areas, the trees cool the ground off with their shading branches and leaves. When the the ground is cooler than the falling rainwater, the warmer rainwater to easily penetrate the earth. Around 85% of the water runoff is retained, with 15% being absorbed by vegetation and humus and about 70% going to recharge groundwater, aquifers and underground stream systems.jenny diagram

In the full hydrological cycle like this, the trees recharge the groundwater table by sending it down through interconnected webs of   tree roots.  This is why biodiverse groupings of different species of trees, like those growing in a natural forest or highly diverse reforestation project, ensure that water is, in fact, penetrating the ground at multiple levels and actually nourishing deeper underground streams and reservoirs instead of draining them like in a monoculture or single species plantation.

In a healthy, full hydrological cycle, diverse tree root systems play another key role in regulation of the water cycle. Roots from all kinds of trees reaching down to all strata of underground levels draw water up from different layers of the soil and underground aquifers. This water then transpires through the tree leaves and rises as water vapor, cooling with altitude and condensing into clouds. Finally, the water aggregates into bigger droplets and precipitates as rain. Some say that water rising from trees is more highly charged and healthy water because it emanates from a living source, with mineral and trace element content much higher than transpiration from the sea, where many creatures have already absorbed the oxygen and carbon dioxide content leaving the water empty.

Now think about what happens to the water when we cut down the trees, particularly around the Equator where the majority of rainwater and oxygen is recycled on our planet. In deforested areas without tree cover, the temperature gradient of the soil is normally so hot that the cooler rainwater cannot penetrate it at all. Instead, the water runs off and just evaporates away. It’s just like when you throw water on a hot skillet and it sizzles and skitters sideways, just evaporating into thin air. Without the trees and cooling clouds to shade and protect and keep the soil cool, the rainwater cannot sink in.

The water vapor in the atmosphere at first increases and the rain spreads out over a much larger surface area instead. Sometimes the rainfall is excessive, then flooding occurs. At the same time, enhanced evaporation causes the atmosphere to become overloaded with water vapor and make the water fall somewhere else instead – sometimes far from the original source of the water vapor. By this process, devastating droughts can also result from the vicious cycle of rain created by a broken hydrological cycle. Yes, a flood in one region begets the next flood, and conversely, a flood can also be the cause of a future drought.

How can drought occur from too much rain? Critical consequence of the half hydro cycle is that there is no groundwater recharge. Think about it. Most of the water is staying on the surface because trees are not rooting the water down and transpiring the vapor upwards in a slow steady balanced process. Instead, the water is rising very fast, in large part as hot vapor and falling as rain without ever actually penetrating the deep levels of the earth. Often, if there aren’t enough trees to hold moisture in the soil, and the winds end up moving the vapor elsewhere which effectively removes the water from that local system.

Where there is no tree cover, the groundwater initially rises and brings with it underground salts, which contaminate the upper levels of topsoil. The plants are not able to metabolize these salts and vegetation and soils dry up and die. Over time the groundwater table will sink and disappear, because there is insufficient rainwater to nourish it and in turn, the supply of nutrients to vegetation from below the ground ceases.

Esteemed scientist Victor Shauberger calls this a biological short circuit which ultimately leads to widespread desertification. Why? The nutrients present in the upper zones of the groundwater table, which are normally drawn up by the trees to a level where they are accessible to the lesser plants are left below instead to sink with the falling ground water. The water table eventually drops to levels far beyond the reach of even the deepest tree roots, taking all soil moisture and trace elements down with it. No water means the desert reigns supreme.

When widespread desertification is the norm, not only is water lost in the deep bowels of the earth, but it also begins to be lost at the great heights of the heavens. The initial greater intensity of thunderstorms and storm activity at first raises the water vapor to levels far higher than normal, even as high as 40 to 80 km above the surface of the planet. Here the vapor reaches altitudes where it is exposed to much stronger ultraviolet and high energy gamma radiation, which break apart the water molecules by disassociating the oxygen from the hydrogen. Due to its lesser specific weight, the hydrogen molecule then rises while the oxygen molecule sinks. This way the water is effectively removed forever – gone gone gone for good.

So what can we do to restore a healthy, full hydrological cycle for our planet? Planting bio diverse trees within 10° of the Equator is one of the best solutions.  In badly deteriorated soils, pioneering species are able to handle the higher levels of soil salts and are critical to plant so they can provide some early shade and ground cover which begins to lower the soil’s temperature. Soil conditions slightly improve as the trees move rainwater deeper into the earth, taking the excess salt down with it. Meanwhile a mix of fruit and hardwood trees can survive in the regenerated soil thanks to the process of creating shade and more soil moisture. Eventually, the pioneer trees die off because the evolved soil conditions are now no longer suitable and the dynamic balance of nature is restored.
