Water crisis

*

Increase in the need of FOOD

Increase in consumption of WATER.

Excessive ater consumption Overpopulation

Increased VITAL NEEDS

=

This is very little water for human

progression…

…We arrive at these effects•Exploitation of aquifers

•Exploitation of rivers

•Construction of infrastructures

•Environmental degradation

•Discharges.

• Great artesian basin in Australia – 1.750.000 km3

• Ogallala Aquifer in USA - 450.000 km3

• Aquifer Arabia in Asia - 160.000 km3

• Guaraní aquifer (South America) – 1.200.000 km3

Exploitation of aquifers

Aquifer Guaraní (South America)

Exploitation of rivers

1. As a consequence, the Jordan River is endangering the Aral Sea.

2. Chemical Industry, Nuclear Centre, Textil Industry, Fish industry.

Discharges

Global Warming effects

• Melting

• Sudden Atmospheric changes

• Depletion of aquifers.

• Biodiversity.

• Displacement of ecosystems

• Health.

Melting snow and ice Reserves

• Kilimanjaro

• Himalaya

Depletion of aquifersSalinization of aquifers caused by water shortage

Salinization of aquifers caused by water extractionAlteration of the ecosystem

Biodiversity: Fauna and flora

Biodiversity: Health

Water Cycle Changes

Direct aspectsWe need more quantity & better distribution

Indirect aspectschanges in the climate of the planet,

global warming

We need :

•Money for investigation

•Good Global Water Politics

•Change of mentality

EffectsUnequal quantitative distributionIndustry and agricultureConsumptionPopulation growthPollutionEnergy sourceTemperatures increase evaporation

Do you think this is funny?........ Some people think that this cartoon strip is funny,

but if we don´t work together to save our planet,

it will become a sad reality…

And if our governments don´t react NOW, what future awaits our new generations?
