14 October is observed as –

World Vegetarian Day
United Nations Day for South-South Cooperation
World Immunization Day
World Standards Day

The correct answer is: World Vegetarian Day.

World Vegetarian Day is celebrated on October 14 every year. It is a day to promote vegetarianism and raise awareness of the benefits of a plant-based diet. Vegetarianism is the practice of abstaining from the consumption of meat (red meat, poultry, seafood, and the flesh of any other animal), and may also include abstention from by-products of animal slaughter. There are many reasons why people choose to become vegetarian, including ethical, environmental, and health concerns.

The first World Vegetarian Day was celebrated in 1977, and it has been observed every year since then. The day is organized by the International Vegetarian Union (IVU), which is a federation of vegetarian societies from around the world. The IVU aims to promote vegetarianism and to educate people about the benefits of a plant-based diet.

World Vegetarian Day is a time to celebrate the many benefits of a vegetarian diet. Vegetarian diets are lower in saturated fat and cholesterol than diets that include meat, and they are also higher in fiber and antioxidants. Vegetarian diets have been linked with a reduced risk of heart disease, stroke, type 2 diabetes, and some types of cancer.

World Vegetarian Day is also a time to raise awareness of the ethical and environmental concerns associated with meat consumption. The meat industry is a major contributor to climate change, and it is also responsible for the suffering of billions of animals each year.
