It takes approximately 123 liters of water to grow one apple. Most of this water comes from natural precipitation (green water) that the trees absorb during their growth. However, some of the water may also come from artificial irrigation (blue water) if the apples are grown in drier areas.

An egg may be small, but it still carries its own water footprint. Approximately 175 liters of water are needed to produce one egg. Most of this water is used for growing feed for the hens, which includes both blue water for irrigation and green water from rainfall. The egg itself is not very water-intensive, but the entire production process demands its share of water.

Chocolate is produced from cocoa beans and sugar, with the largest cocoa producers being Côte d'Ivoire, Ghana, Indonesia, Nigeria, and Ecuador. The water footprint of chocolate depends on the cultivation methods used—most of the water comes from rainfall (green water), while only a small amount comes from intensive irrigation (blue water). Additionally, the use of fertilizers and pesticides can pollute water (gray water), as well as the processes of production, packaging, and transportation of chocolate.

The top producers of coffee beans are Brazil, Vietnam, Colombia, and Indonesia. Shade-grown coffee plants utilize rainwater (green water), while sun-grown varieties require intensive irrigation (blue water). Coffee cultivation can pollute water due to the use of fertilizers and pesticides (gray water) and the resource-intensive processing, particularly wet washing. Dry processing is more water-efficient but still consumes a certain amount of water. Additionally, pollution related to the packaging and transportation of coffee further contributes to its overall water footprint.

Tea, a popular beverage worldwide, is primarily grown in countries like China, India, Kenya, Sri Lanka, and Vietnam, where tea plants mainly rely on rainwater (green water). However, in drier areas, they may receive supplementary irrigation (blue water). During cultivation, fertilizers and pesticides are sometimes used, contributing to gray water, which is further associated with the processing, packaging, and transportation of tea.

Beer is not only a popular beverage but also a product with a significant water footprint. The largest beer producers are China, the USA, Brazil, and Mexico. Most of this water is consumed in the cultivation of raw materials, such as barley and hops, while the remainder is used in the actual brewing process. The Czech Republic, renowned for its beer tradition, ranks 21st among the world's beer producers.

Chickens are primarily raised in the USA, China, Brazil, and the EU. This production mainly relies on rainwater (green water) and irrigated water (blue water). However, raising chickens can lead to water pollution (gray water) due to manure runoff and the use of fertilizers and pesticides in feed production.

Beef is primarily produced in the USA, Brazil, China, Argentina, and Australia. Cattle spend most of their lives on pasture but are fed corn and hay in feedlots towards the end of their lives. The feed mostly relies on rainwater (green water), but an increasing amount is irrigated. However, beef production can pollute water, as fertilizers and pesticides from fields and manure runoff can end up in rivers and lakes. The beef industry also has a significant environmental impact, as high water consumption and greenhouse gas emissions contribute to the degradation of natural resources. For instance, beef production requires about eight times more feed (on a dry weight basis) per kilogram of meat compared to pork and eleven times more than chicken.

Bread made from wheat flour requires a significant amount of water for its production. Wheat, the main ingredient in bread, is primarily grown using rainwater (green water), but in some areas, irrigation (blue water) is also necessary. Additionally, gray water, which refers to pollution caused by the use of fertilizers and pesticides, can also contaminate water sources. In the Czech Republic, wheat is mainly cultivated in fields that utilize natural rainfall, and most of the water used for wheat production comes from these precipitation sources.

The water footprint of a hamburger is influenced by the amount of water required to produce its individual ingredients. Average water footprint values per kilogram of ingredients are used for the calculation. The main components include the beef patty, a slice of tomato, a slice of cheese, a leaf of lettuce, and the bun. The beef has the largest water footprint because a significant amount of water is needed for feeding and raising cattle. Other ingredients, such as tomatoes, cheese, and lettuce, have a lower but still notable impact on the overall water footprint of the hamburger.

Cotton, the material from which t-shirts are made, is a very "thirsty" crop—requiring an enormous amount of water for cultivation. In addition, the actual production of textiles, such as dyeing and washing the fabric, is also water-intensive. Whether it's the irrigation of cotton or the processes in the textile industry, the water footprint of a single t-shirt is substantial.

The production of a single pair of jeans requires approximately 11,000 liters of water. Water is consumed not only during the cultivation of cotton, from which the jeans are made, but also in later stages such as dyeing, finishing, and washing the fabric. These processes not only increase water consumption but also lead to pollution—industrial wastewater contains large amounts of dyes and chemicals. With over 3.5 billion pairs of jeans produced annually, the scale of this environmental impact is significant.

The water footprint of leather shoes is substantial, as their production involves several water-intensive processes. The majority of water is consumed during the cultivation of materials, such as leather and natural textiles, that make up the upper part of the shoes. Leather, primarily sourced from cattle, undergoes a tanning process, where it is treated with chemicals and water to make it durable and long-lasting. This process is water-intensive and often results in water pollution from chemicals and dyes. Additionally, significant water consumption occurs in the production of other materials, such as textiles and synthetic components. Water is also used during various manufacturing stages, including shaping and securing the form of the shoes.

The overall water footprint ranges between 300 and 2,600 m³ per ton of paper, which corresponds to approximately 2 to 13 liters per A4 page. The largest portion of water is consumed during the cultivation of trees, with most of the water evaporating from the soil and leaves (known as green and blue water). Interestingly, using recycled paper can significantly reduce the water footprint—on average by 40%. Additionally, selecting locations for paper production and using tree species that require less water can contribute to lower water consumption.

An average showerhead uses approximately 12 to 15 liters of water per minute, meaning that a 10-minute shower can consume up to 150 liters of water. For more water-efficient options, low-flow showerheads are available, which use 6 to 9 liters per minute, resulting in a total of 60 to 90 liters of water for a 10-minute shower.
