-Will Ecofont's innovation save the planet? Well, probably not. But at the very least, it's prompting people to practice a more sustainable way of life - especially in seemingly insignificant things that are easily overlooked.
I have looked the word 'practice' up in dictionaries, but I still can't understand what it means in the above case. Would you please interpret it for me? And could you please give me one or two more examples that have similar meanings of the word? Thank you!
