If you don't know them yet, it's time to discover the 17 Sustainable Development Goals (SDGs) for the future of the planet. They are at the heart of the 2030 Agenda for sustainable development adopted in 2015 by the United Nations.
The goals start from the very basis of the Maslow Pyramid: zero hunger, good health, clean water, no poverty. They also address key issues for humanity such as education, gender equality, reduced inequalities, decent work for all, peace and justice. And then they deal with the preservation of the planet: responsible consumption and production, clean energies, sustainable cities, climate action, life on land and below water.
To discover the 17 goals in more details, have a look at the UN website and discover the action plans behind each goal: https://sdgs.un.org/goals
