Listen to the Scientists.
Climate Change is Real!
Make America Think Again!
Science and Education are crucial to a Sustainable Future!
Think Global; Act Local (I prefer “Think Globally, Act Locally, personally)
Alternative Energy, not Alternative Facts
With that last one, I must persist in my role as English Language Arts teacher as much as my role as progressive activist. Positive statements are much stronger than negative. If you, the sign maker, need the word NOT in big letters, go back and rephrase it. For example, “Climate Change is Real!” is much stronger than this slogan.
The phrase “Liberal Conspiracy” is more likely to stick in someone’s mind than the idea that “Science is Real.” The sign to the right has a major problem, too: no one can read it. The letters are much too thin and faint, and they fade completely in the bright sunlight.
As for message, this one gets right to the point.
