Why is water considered a key resource?

Water is essential for survival, making up 2/3rds of a person’s body. It is used to absorb nutrients, remove waste, maintain hygiene, support farming, cooling, and production of goods.

Humans need around 2 litres a day depending on activity and climate.

What are the daily calorie needs for humans, and what are the consequences of not meeting or exceeding these needs?

Humans need about 2,000-2,500 calories per day. Eating too few calories causes weight loss and health problems, while eating too many leads to weight gain and related health issues.

How is energy used in developed societies?

Energy is used to heat homes, run schools, power hospitals, cook food and power transport.

Electricity, a secondary energy source, is generated from primary sources like wind and fossil fuels.

How does uneven distribution of key resources affect global development?

Uneven distribution of resources like water, food and energy leads to disparities in health, economic growth, and living standards between countries, contributing to uneven global development.

What are the differences in calorie intake between High-Income Countries (HICs) and Low-Income Countries (LICs)?

In HICs, calorie intake is often higher than needed, leading to obesity.

In LICs, undernourishment is common due to insufficient calorie intake, leading to health issues like stunted growth and weakened immunity.

What regions are most affected by water scarcity, and what is a water footprint?

Central Africa, Northern Africa, and the Middle East are most affected by water scarcity.
