General note on trees
our consumption of water is ever increasing and our drinkable water supply is shrinking because of polution ,and the production of potable water is less all the time because of deforestation.
the forrests make most of the water that we can drink or use for plant growth(sweet water)
some is condensed from the sea but that reaches only the coastel aereas .
the bulk however,comes from the forests who feed the rivers and keep them running all year round,with their excess subteranean water,and from the rainfall which also comes from the trees .the trees condense water from the atmosphere in the night with the surfaces of the leaves,this feeds the rivers after the tree has had enough the excess moves on to subteranean water,
on the other hand in the day water that is brought up by the roots and that is within the foilage evaporate and creates clouds the dust from the leaves seeds the clouds and rain is the results
this process is called precipitation
If we kill all the trees,we kill the rivers .we kill the rain. we kill us.
the trees also absorb the heat in the day and heat up the place in the night ,so they keep the temperature confertable to live in.
desertification is also a result of bad agricultural methods and deforrestation
in the dessert the nights are freezing cold and during the days you burn up
the saharaa is growing by 7 kilometres every day.
two major desserts in northern china are growing together making one giant dessert and,causing dust storms so making thousands of people refugeese
the trees evaporate a mist which ,which protects us from the strong rays of the sun .
in the days of the dinasaurs this planet was under an aquiferus manta ,a mist that covered the entire earth ,and there were no desserts .
Count how many there are today,and all of them are as a result of mans actions.
the sahara used to be forrests
arabia ,irak ,iran used to be fertile lands in biblical times
Ghengas Kahn burned all the forrests here and filled the well with water and so turning vast lands into dessert.
Modern agriculture today is doing the same as ghengas kahn but in much bigger territories.
these are some of the reasons why trees are important.
so to counter act these fatal processes we must reforrest and at the same time reduce our carbon emissions.
most governments are aware of these and many first world countries now include programs to reduce their carbon emissions.
the world bank pays large subsidies for farmers to plant trees especially a tree called Pawlomia because it is one of the better ones that capture carbon.
In the sierras in Mexico in Guerrero we are planting Pawlonia to capture carbon and the World bank gives large subsidies for that,
also coffee is the most recomended bush because it lives beneath the trees ,and forrests are created intead of destroyed for agricultural reasons.
En la region Montaña(parte alta) de Guerrero, los productores siembran un arbol llamado Cuajinicuil, este arbol es de muy rápido crecimiento, se clasica dentro de la familia de las leguminosas por lo que es un exelente fijador de nitrogeno. El arbol es utilizado con exelentes resltados para la sombra del café, además su fruto (vaina) es comestible pues sus semillas estan cuviertas de un material fibroso y muy dulce. Sus semillas son utilizadas tambien como alimento para lo cual estas deben pasar por un proceso de cocimiento (hervidas). La cascara de la vaina se utiliza para alimento del ganado. (Es Arbol perene)
so plant a tree every week,and help us save the world
