Most global challenges, including global warming, food for everybody, the race for sustainable energy, water quality, dwindling raw materials, and health problems, are chemical problems by nature. Therefore, Humankind cannot meet these challenges without the chemical sciences and will not solve any of these problems without global cooperation. Chemists have always been doing much better than politicians in meeting these challenges, working together across borders through unique collaboration and friendship. Despite fundamentally different political systems and cultural diversity, chemists go beyond borders, find each other, share their findings, and solve problems together.
