Pescetarianism is a specific dietary practice centered on plant-based foods and seafood. 
A typical pescetarian diet relies heavily on fresh produce and plant foods. 
There are several ways to categorize these eating patterns based on specific rules. One type is the standard pescetarian diet, which allows for eggs and dairy. Another is the seagan diet, which removes those animal products to focus more on plants. Some people use pescetarianism as a transition toward full vegetarianism. Others view it as a practical or ethical compromise. These distinctions allow individuals to balance nutritional needs with their personal beliefs.
The history of eating fish instead of meat spans many centuries and cultures.
Today, pescetarianism is a recognized global dietary trend with specific demographics. Research from 2017 to 2018 indicates that approximately 3% of adults worldwide are pescetarian. In the United Kingdom, studies show between 3% and 4% of the population follows this diet. In Africa and the Middle East, the incidence is slightly higher at about 5%. 
People choose this diet for several significant environmental and ethical reasons. One major motivation is sustainability and reducing a person's carbon footprint. A 2014 lifecycle analysis estimated that a pescetarian diet could provide a 45% reduction in greenhouse gas emissions compared to an omnivorous diet. 
Ultimately, pescetarianism connects individual health to broader global systems. It relates to the "green movement" and the goal of global food sustainability. By choosing seafood over land animals, people attempt to manage the impact of their food on the earth. This includes reducing the nitrogen footprint and protecting land resources. Whether for nutrition, ethics, or the environment, the diet represents a specific way of interacting with the world's food systems.
