Today's holiday is a reminder of the importance of supporting and promoting art as a means of cultural enrichment and an important component of society and the economy.
International Day of Environmental Knowledge
Since the middle of the 20th century, environmental education, both worldwide and in Ukraine, has been considered a priority area for reforming the education system. Attention to the formation and development of environmental education began to grow after the Stockholm Conference on the Protection of the Environment, which in 1972 adopted a recommendation on the creation of an international program on environmental education.
The content of environmental education is aimed at forming a personality with an environmental worldview that is set to comply with the norms of environmentally sound behavior and to perform practical actions to protect one's own health and the environment, to develop a system of scientific knowledge that reflects the philosophical, moral, ethical, socio-economic, technical and military aspects of environmental education.
McDonald's Day
Fast food lovers can join the celebration of McDonald's Day today.
The event is dedicated to the fact that on April 15, 1955, Ray Kroc opened the first franchise of this fast food chain in the American state of Illinois.
The history of McDonald's began in 1940, when brothers Richard and Maurice McDonald opened a restaurant in California and revolutionized the fast food industry. Ray Kroc supplied kitchen utensils to McDonald's and persuaded the brothers to allow him to open a franchise.
Currently, McDonald's has about 40,000 locations in 120 countries, serving more than 70 million visitors every day.
