WATER FOR LIFE ACQUA PER LA VITA

CLASSE 1^A, a.s.2012/13

Page 4: Water for life

Between 70 and 75 percent of the earth’s surface is covered

with water. TRA IL 70 E IL 75 PER CENTO DELLA SUPERFICIE TERRESTRE E’ RICOPERTA DI ACQUA.

Page 5: Water for life

The total amount of water on the earth is about 326 million cubic miles. The same

water that existed on the earth millions of years ago is still present today.

LA QUANTITA’ DI ACQUA PRESENTE SULLA TERRA E’ CIRCA 326 MILIONI DI MIGLIA CUBICHE. LA STESSA ACQUA CHE ESISTEVA MILIONI DI ANNI FA ESISTE ANCORA OGGI.

Where is Earth's water located and in what forms does it exist?

DOVE SI TROVA L’ACQUA SULLA TERRA E SOTTO QUALE FORMA?

Page 7: Water for life

Water has three different states:

liquid, solid and gas. Pure water has no smell and no taste,

it also has a pH level around 7. L’ACQUA SI TROVA IN TRE DIVERSI STATI: LIQUIDO, SOLIDO E GASSOSO. L’ACQUA PURA E’

INODORE E INSAPORE E HA UN PH DI CIRCA 7.

• Water is absolutely essential to the human body’s survival. A person can live for about a month without food, but only a few days without water. (L’ACQUA E’ ESSENZIALE ALLA SOPRAVVIVENZA DEL CORPO

UMANO. UNA PERSONA PUO’ VIVERE PER CIRCA UN MESE SENZA CIBO MA SOLO POCHI GIORNI SENZ’ACQUA)

• Roughly 70 percent of an adult’s body is made up of water. (CIRCA IL 70% DEL CORPO DI UN ADULTO E’ FATTO DI ACQUA)

• Water aids in the digestion process and prevents constipation. (L’ACQUA FAVORISCE I PROCESSI DIGESTIVI E PREVIENE LA COSTIPAZIONE)

• Water is the primary mode of transportation for all nutrients in the body and is essential for proper circulation. (L’ACQUA E’ ESSENZIALE PER UN’ADEGUATA CIRCOLAZIONE E FAVORISCE IL TRASPORTO DI TUTTI I PRINCIPI NUTRITIVI NEL CORPO)

Drinking adequate amounts of water can decrease the risk of certain types of cancers,

including colon cancer and breast cancer. BERE LA GIUSTA QUANTITA’ DI ACQUA PUO’ RIDURRE IL RISCHIO DI AMMALARSI DI CERTI TIPI DI CANCRO

COME QUELLO DEL COLON E QUELLO AL SENO

Page 12: Water for life

The daily recommended amount is eight cups, but not all of this water

must be consumed in the liquid form. LA QUANTITA’ GIORNALIERA RACCOMANDATA E’ DI 8 BICCHIERI, MA NON TUTTA QUEST’ACQUA

DEVE ESSERE CONSUMATA IN FORMA LIQUIDA.

Page 13: Water for life

Water dissolves more substances than any other liquid. Wherever it travels,

water carries chemicals, minerals, and nutrients with it.

L’ACQUA PUO’ DISSOLVERE PIU’ SOSTANZE DI QUALUNQUE ALTRO LIQUIDO. DOVE PASSA TRASPORTA SOSTANZE CHIMICHE, MINERALI E NUTRIENTI.

But when there is not enough potable water for everyday necessity, the threat of awater crisis is realized.

(MA QUANDO NON C’E’ ACQUA SUFFICIENTE PER I BISOGNI QUOTIDIANI SI CONCRETIZZA LA

MINACCIA DI CRISI IDRICA)

Page 15: Water for life

Fifty years ago, when there were half the current number of people on the planet, the common

perception was that water was an infinite resource. People were not as wealthy then as they are today, consumed fewer calories and ate less meat, so less

water was needed to produce their food. CINQUANTA ANNI FA, QUANDO SUL PIANETA C’ERANO LA META’ DEGLI ATTUALI ABITANTI, LA RISORSA ACQUA SI PENSAVA FOSSE INFINITA. LE PERSONE NON VIVEVANO NELLE CONDIZIONI DI BENESSERE ATTUALI, CONSUMAVANO MENO CALORIE, MANGIAVANO MENO CARNE, PERCIO’

ERA NECESSARIA MENO ACQUA PER PRODURRE IL LORO CIBO.

Globally, the problem is getting worse as cities and populations grow, and

the needs for water increase in agriculture, industry and households. GLOBALMENTE IL PROBLEMA PEGGIORA MAN MANO CHE LE CITTA’ E LE POPOLAZIONI CRESCONOE IL BISOGNO DI ACQUA AUMENTA NELL’AGRICOLTURA, NELL’INDUSTRIA E NEI

LAVORI DOMESTICI.

About 700 million around the world

currently suffer from water scarcity, they

could increase to more than 3 billion by

2025.

ATTUALMENTE CIRCA 700 MILIONI DI PERSONE NEL MONDO SOFFRONO PER LA

SCARSITA’ DI ACQUA E POTREBBERE DIVENTARE PIU’ DI 3 MILIARDI NEL 2025.

World Water Day

(WWD)

Water Scarcity is the

theme for World
