The project "Let's turn off the light and sing for the HOUR OF EARTH!" is an event that we propose from March 2 to April 2, 2020, organized on the occasion of the Earth Hour, which takes place on March 28, 2020 internationally, organized on the last Saturday of March of each year, starting with 2007, which consists in extinguishing the light and stopping non-essential household appliances for one hour, voluntarily, both by individual consumers and institutions. It is a project designed to draw attention to climate change and the loss of biodiversity, organized with the purpose of raising awareness of the negative impact on the environment caused by the excessive consumption of energy resources.
