2. Read the passages given below
Both water and energy are integral parts of the human body, wy weight abtront of
adult's human body is water and dehydration is one of the biggest single kniers of
children in the modern world. Life without water is unthinkable
The human body needs its daily intake of food to meet its energy requirements, which
according to the Food and Agriculture Organisation of the United Nations is about 1.800
kcal per day. Life without energy is equally unthinkable,
The energy that we take in through food again depends, amongst other things, on the
water for agriculture and often that water is pumped with electrical or other forms of
energy. The interdependence of energy and water is evident.
The world at large seeks both water and energy security. The Worldwatch Institute
estimates that about 1.1 billion people (one-fifth of the world population) live in areas of
physical water scarcity and another 1.6 billion are facing economic water shortage (when
existing water sources cannot be used because of a lack of investment in water related
infrastructure). We will probably have a world population of 9 billion by 2050 and this
will put further stress on the water sourcing and supply systems. Here again, the
connection between energy and water is evident: globally about 70% of water
consumption is for the agricultural sector. No water, no food, no energy
Actions needed on the waterfront include a reduction in water usage for agriculture
(pump efficiencies, drip irrigation instead of flood irrigation, change in crop patterns),
recycling of water, extensive rainwater harvesting programmes, stoppage of run-offs and
water pollution.
We need to remind ourselves that the fossil-based energy that we rely on so much for
almost everything we do is stored solar energy. And while the sun took over 150 million
years to store its energy in the form of fossil fuels, we are busy discharging that huge
solar battery in a matter of a few hundred years.​
