The main goal of the article is to understand how water is used in food production and processing. The researchers used the concepts of 'Virtual Water' and 'Water Footprint' to analyze global water consumption. They found that around 70% of the world's water is used for agriculture, especially for growing food. In contrast, food processing and other activities in the food supply chain use much less water.
