Have you considered how Earth feels when you are having revels or a celebration? The past Valentines Day is a fine example to exhibit the lifestyle of people. Who didn’t buy flower for his girlfriend in the past Valentines? The ones not being given a bunch of flower but seeing other friends receiving them may feel left out and not cared about by their boyfriends. But do the ones who bought flowers, do you know where these flowers come from? Presumably, most of them come from foreign countries and excluding the wrappings or others things, they still bring a lot carbon dioxide to the Earth.
Aren’t there other, maybe better ways, to show your affections towards your lover? Have you considered singing a love song? Or giving her another kind of presents like chocolate? Many say that peer pressure is one of the causes of buying their lovers flowers.
All in all, Valentines is only a day, a festival for the people to show their affection to their love ones and the simplest and purest way of showing it may be better than giving a rather conventional gift. Flowers.
