On Tuesday 10 December 2019, the Junior and Senior Science Clubs hosted two presentations by the AKTH organization. The talks entitled ‘Τηγανοκίνηση: Ανακύκλωση του χρησιμοποιημένου μαγειρικού λαδιού’ and ‘Θαλάσσια ρύπανση: Πηγές, επιπτώσεις και λύσεις’ provided the attendees with insights on the state of the environment and useful tips to help reverse the negative human effects that have been taking place for a few centuries.
