For the environmentally concerned fellow humans I would totally suggest a vegan diet (at least for 5/7 days per week!) and a huge cut of energy expenses especially petroleum-based although not every country has currently many non coal alternatives for transportation or air-conditioning... also joining massive protests coming up this year like #earthstike is a great idea for a systemic change!

And sorry for the really long posts! 😅
