On March 22, we celebrate World Water Day. This celebration was established by the UN General Assembly as part of Agenda 21, during the 1992 Earth Summit (UNCED) conference in Rio de Janeiro (Brazil). The reason was that over a billion people in the world suffer from a lack of access to clean drinking water. It aims to raise awareness of global water challenges, a reminder that water is essential for the maintenance of life and must be available in sufficient quantity and available for all inhabitants of our planet. Always take all available efforts to obtain the best possible water quality. Currently, about 800 million people suffer from lack of access to clean drinking water.
Let not be fooled by the term "blue planet", which is sometimes referred to as Earth. Although about 70% of it is covered with water, only 2.5% is fresh water, suitable for drinking. It is our treasure - let's take care of it while we still have time for it.
For this reason, all over the world, but also in our closest neighborhood, actions are taken on a different scale, from workshops in schools, humanitarian actions through PAH, as part of GDOS, state forests, public and scientific institutions, UNESCO and other larger committees and even smaller organizations and foundations.
We invite you to listen to and watch the lecture by the director of the Institute of Oceanology of the Polish Academy of Sciences, Jan Marcin Węsławski, on the valorization of water. "How is the value of water assessed?" Lecture at the invitation of the Polish Limnological Society provided in Polish.
