list 5 reasons why groundwater is important?

Answer 1

underwater reservoirs (aquifiers) suport forrests and supply rivers and are inturn replenished by the forrest precepitacions ,like rain(2)

,it can be pumped for drinking water or for irrigation for
agriculture and used for aquaculture,(3)

and ground water is a store for sweet water that will not return to the sea it is safe(1)
sweet water is scarce
only 3% of the global water is sweet and 75% was locked in Ice and a lot of this has melted and run into the sea becoming salted
,most of the water we gor is locked in forrests (and thes are under attack globally)and the resst is in underground water supplies rivers and lakes ,and lots of this is becoming poluted
so it is a fraction that is available to us in uncontaminated conditions
aquifiers is such a resource
and the spraying of agro chemicals is endangering that as well

the deep underground carbon aquifiers are best alone because the do not get replenished and can colapse if pumped dry causing sinkhole miles deep or be filled with sewage instead which has happened in some parts ot the USA


there is a lot of detail on water in this book
the Permaculture designers manual by Bil Mollison cost about 40 dollars.
and is the best all round book you can get.(tagiari publishing, [e-mail])

Permaculture means permanent agriculture
a concept put forward by Bill Mollisson in the 60`s
which is a complete hand book for environmental design.
for those who seek an ambiotic relationship with our planet
With practical solutions for energy systems ,infratructure ,housing,
animal shelter ,water systems and sustainable agricultural practises.
With the world and it`s history as it`s source
From the chinampas of Mexico to the teraced gardens of the Andes.
From the dessert whadis to the steppes of Russia.
Covering all climatic conditions temporal, dessert, humid and dry tropics.
with chapters on soil ,Water harvesting and land design,
Earth working ,Spirals in nature,Trees and water ,utilising energy flows,
Strategy for an alternative nation

Answer 3

photograph voltaic for plant photosynthesis (meaning nutrition for all residing animals in the international). warmth tocontinual climate (to grant rain, snow, and sunshine) for residing issues to stay and advance. Gravity to maintain the Earth in a good orbit around the sunlight (so we get the photograph voltaic and warmth on a daily basis). photograph voltaic magnetic field to guard the planets (alongside with Earth) from cosmic radiation from outdoors the photograph voltaic device. Sorry, this is barely 4 i'm able to think of of off the right of my head (in case you considered it you will possibly have considered a minimum of three of those your self). If its a examine challenge, shouldn't you do particularly some the examine?
