Climate change is not a problem in isolation ,What people do is mixed up with it ,such as desertification because of overgrazing and intense and irresponsible farming ,using fertilizers and herbicides and pesticides,
As well as the overpumping of surface and carbon Aquifers,
Deforestation resulting in wind and water erosion or landslides.
And the forrest fires that are caused by slash and burn methods gone out of control
this also affecting wildlife because of loss of habitat
on top of all this is Soil.Water and Air polution caused by Humanity
in North Africa,India,Mexico ,millions of people are effected by land loss and desertification and some have died as a result,
And there have been heat waves or cold spells and floods that have killed people in France,Mexico,Africa,India,
And now many animals are becoming sick because of changes in temperature ,
vital links in the food chains are disapearing affecting other species further along in the chain
90% of the feral (wild) bee population in the United States has died out.but this is mostly because of a parasite whether or not the increase of this mite is related to clomate change i dont know
In the Netherlands bee diversity is down 80 percent in the sites researched, and "bee species are declining or have become extinct in Britain."
wildflowers that depend on pollination have dropped by 70 percent
we are witness to a mass exstinction ,for the first time since the dinosaurs, of the earth's estimated 10 million species, 300,000 have vanished in the past 50 years. each years, 3,000 to 30,000 species become extinct.
everything is happening so fast it is not possible to monitor things any more.
,the Sahara is growing by 7 kilometers a year
and most of the desserts we know are a results of mans actions ,and they are increasing ,not getting less ,in the dinosaurs days ,there were few desserts.
collectively this planet is drying up ,
each degree rise in temperature means 10%crop loss
and there is less and less water (because of deforestation),to irrigate this production ,
and there are less and less farmers to do it..
Arable lands and their farms are lost all over the globe. Many farmers sons abandon farming and head for the cities.
Northern China is drying up, what once were millions of food producing people, are now hungry refugees ,running for their lives from the all consuming dust storms.
This will have a great effect on world food prices when they start buying at what ever cost, to feed their people.
25% of the planets surface is land
75%of the surface is water and it is rising
97%of the Earths water is salt
fresh water is only 3% of all the Earths water
most of it is beyond out reach
STORAGE or Location of % of the fresh water
ice and glaziers 74%
groundwater 800 meters + 13.5 %
groundwater less than 800meters 11.o%
Atmospheric in circulation 0.0035%
frozen land or permafrost is not included and represent an unavailable storage of 40%
now much ice is melting and running into the seas fresh water lost for ever.
the ice of the North pole is already in the water and it wont make a difference to sea levels ,but the ice of the Glaziers .mountain snow,Antarctica and Greenland is on the land and this WILL affect sea levels ,the lost of fresh water is the worst part of this ,and right now there is a rush to the ice bergs to save some of it to put in bottles.
so of the 3% about 11.6 ,is easily available to us ,in rivers, lakes and ground water surface aquifers,more and more of this is becoming contaminated
Each year farmers have to feed some 70 million more people than the year before but with less topsoil.
Over the last half century,
Population growth & rising incomes have tripled world grain demand from 640 million tons to 1,855 million
In the near future the global farming community will not be able to feed every body ,food prices will continue to rise. .
potable water is getting at critical levels and people are already fighting over water this will only get worse Source(s) Lester E Brown is the director and founder of the global institute of Environment in the United states .he has compiled a report based on all the satalite information available from NASA,and all the information that has
