This day is remembered in much of Latin America, Spain and the United States. Its origin dates back to the beginning of the 20th century, initially spontaneously and unofficially, to commemorate the new cultural identity, the product of the encounter and fusion between the indigenous peoples of America and the Spanish conquerors, in addition to the enhancement of the Hispanic-American cultural heritage.

The main principle which World Food Day celebrates is the furtherance of food security all over the world, especially in times of crisis. The launch of the Food and Agriculture Organisation by the UN has played a huge role in taking this worthy goal forward. Its annual celebration serves as a marker of the importance of this organisation and helps to raise awareness of the crucial need for successful agriculture policies to be implemented by governments across the world to ensure there is ample food available for everyone.

Although it is undoubted that this day should be celebrated, the origin of the chosen date is somewhat uncertain. It is celebrated every October 21 and it was created with the intention of conserving natural resources and achieving efficiency in the energy area.

Caring for the environment is a task that corresponds to all of us, because we live here, we share here and the goal is to be able to preserve and protect it for future generations.

In this area of ​​energy saving, initiatives such as Earth Hour have been created, which is held on the last Saturday of March and consists of a voluntary one-hour electricity blackout.
