Both water and energy are integral parts of the human body. By weight about 60% of an adult's human body is water and dehydration is one of the biggest single killers 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.
Q. We get ________ from food.
  • a)
    energy
  • b)
    life
  • c)
    fuels
  • d)
    water

Understanding Energy from Food
Food is essential for human survival, and one of its primary roles is to provide energy. Here’s a breakdown of why the correct answer is option 'A'—energy.
1. Energy Requirements
- The human body requires energy to perform essential functions such as:
- Breathing
- Digestion
- Physical activity
- According to the Food and Agriculture Organisation of the United Nations, an average adult needs about 1,800 kcal of energy daily.
2. Source of Energy
- Food contains macronutrients—carbohydrates, proteins, and fats—that are broken down by the body to release energy.
- Each macronutrient contributes different amounts of energy:
- Carbohydrates: 4 kcal per gram
- Proteins: 4 kcal per gram
- Fats: 9 kcal per gram
3. Importance of Energy
- Energy is crucial for:
- Growth and development
- Maintaining body temperature
- Supporting metabolic processes
- Without adequate energy intake, the body cannot function optimally, leading to fatigue and various health issues.
4. Interconnection with Water
- Food production relies on water for agriculture, illustrating the interdependence of food, water, and energy.
- Efficient use of water in agriculture ensures a sustainable food supply, which in turn supports energy needs.
In summary, food is a vital source of energy for the human body, making option 'A' the correct answer. Understanding this relationship highlights the importance of sustainable practices in food production and water management.
