How trees bring water ?

 trees make water it's the truth and 

 I'm going to explain exactly how 

 trees can both create water when

they're planted and Destroy water when

they're removed so let's start with the

simple structure of a tree as a giant

net for capturing atmospheric moisture

and nutrients the combined surface area

of a trees leaves or needles branches

and Trunks is surprisingly large when

you imagine humid air or fog moving

through the tree and intercepting each

of its surfaces

atmospheric humidity condenses on every

surface of the tree as moist air rolls

through the water is settled out of the

atmosphere and collected by the tree and

it's not only moisture that's caught by

the tree's net it's also fine particles

of dust pollen spores insect bodies bird

droppings and more that are all

collected by the vast net of the tree's

structure so when moisture is collected

by the tree sometimes in the form of

frost when it's cold

it drips off the leaves bringing all of

these atmospheric nutrients with it to

the soil level and down into the tree's

root zones

this humidity harvested by trees can

actually account for a large proportion

of the total precipitation that falls on

a forest and then when the rain comes

the whole surface of the tree is a giant

intercept for falling rain each

raindrops fall is broken when it hits

the tree and splatters into a fine Mist

where the structure of the tree itself

directs the flowing water through it

down the branches and trunk dripping

through the interwoven network of leaves

washing all the dust and pollen and bird

poop gently down into the tree's roots

out the soil below the trees already

spongy from all of the leaf litter and

sheltered environment beneath the tree

so the water soaks through the soil

sponge and is drunk up by the tree's

roots the tree becomes full of water

just like the human body on average is

60 percent water the body of a tree on

average is 50 percent water both above

and below ground in the root system

so imagine a forest on top of a hill so

with 50 of every tree made up of water

you can think of a forest on a hill as

like a Lake's worth of water just

sitting there remember the total canopy

of a forest is intercepting fog humidity

and nutrient-laden dust so it's

collecting water and nutrients even when

it's not raining. But when it rains the

whole canopy breaks the speed of the

raindrops and gently drips the rain

where the tree structure directs it to

and then the spongy soil soaks it up and

The Roots drink it in and what's not

absorbed flows downhill into the creeks

and rivers below. So the hilltop Forest

moderates the time. It takes for water to

move through the hill it slows the

duration that it takes the water to move

down through the landscape and keeps a

big storage of water at the top of the

hill in the form of the forest which

will slowly release water over the

seasons as gravity pulls it down but at

the same time that gravity is pulling

the water down the tree is also pulling

the water up and out of the leaves and

back up into the atmosphere through

evapotranspiration and evaporation and

it's not just water that's rising up and

out of the trees a forest releases many

tiny particles like pollen Leaf dust

bacteria fungus spores that float up

into the air when these tiny particles

encounter moisture floating through the

atmosphere like clouds then the forest

particles provide nuclei for raindrops

to form around

so we have clouds that have formed from

evaporated water over oceans and seas

moving through the atmosphere over land

and then they encounter the air above a

forest which is filled with water vapor

in organic particles and guess what

happens when they all meet

it rains studies in the Amazon showed

that the forest there actually returned

75 percent of its water back into the

atmosphere in amounts high enough to

form their own rain clouds but it's not

just the wet Tropics we're talking about

trees and every climate have a

partnership with the atmosphere trees

collaborate with the atmosphere to

produce rain and snowfall and so the

clouds that you see move overhead are

not just ocean water vapor they're

Forest water as well in fact

forested mountain ranges help to Leap

Frog water from the coasts to the

interior of the continents as water

vapor hops from one mountain range to

the next

the rainfall in the interior of the

continent is dependent on the forest on

the coast so when you remove trees from

this cycle through deforestation you

break the system it rains Less on Barren

land because forests aren't there to

intercept the clouds with water vapor

and raindrop nuclei and when you break

the system on the coasts it then has sad

repercussions for rainfall further

Inland it's called drought remember

trees don't only bring water vapor and

raindrop nuclei into the atmosphere they

also moderate the flow of water down

into the landscape making it more

consistent and steady because the forest

is a giant sponge of water storage so

when you remove that sponge and then the

rain falls the water rushes down off of

bare hillsides quickly below and all at

once and down below the barren Hills you

get floods in The Valleys so my friends

this sorry State of Affairs is what we

call the drought flood cycle and this is

where much of the world is today

long droughts punctuated by short

intense floods and shortly after the

floods are over the droughts start again

but as I've shown in many cases the

course to take is obvious

trees make water

trees moderate the flow of water

forests are part of the circulation of

atmospheric moisture it's really pretty

basic and hence the solutions are basic.
