Hundreds of thousands of people around the world took to the streets for Saturday’s March for Science – and the signs they made were incredible. Many targeted the Trump administration‘s recent budget cuts to environment-related programs and the President’s perceived hostility to science, which served as a major spark for the movement. Read on for a look at the funniest, the cleverest, and the most creative signs we spotted at the marches around the globe.

With over 600 rallies across the world, the “celebration of science” advocated the use of evidence-based policy making in all levels of government, with climate change a core topic. Inspired by the 2017 Women’s March of January 21, 2017, the March for Science amassed large support in a short amount of time thanks largely to social media channels like Facebook and Twitter. Co-led by nonprofit Earth Day Network, the March for Science was officially declared non-political although many protestors used it as an opportunity to protest Trump’s administration. The main march kicked off in the early morning with a mass gathering on Washington D.C.’s National Mall followed by a march down Constitution Avenue toward the Capitol in the afternoon.

Many protestors displayed homemade signs with many indirectly and directly attacking Trump with slogans such as “What do Trump and atoms have in common? They make up everything,” “Mr. President, science gave us Romaine,” and “Pruitt Plus Trump Equals Bad Chemistry.” A few hours after the marches kicked off, President Trump released a statement on Saturday saying: “Rigorous science is critical to my administration’s efforts to achieve the twin goals of economic growth and environmental protection. My administration is committed to advancing scientific research that leads to a better understanding of our environment and of environmental risks. As we do so, we should remember that rigorous science depends not on ideology, but on a spirit of honest inquiry and robust debate.”

Many scientists, however seem to have a beef with the “alternative facts” coming from the current administration. A good many of the signs we spotted at the Science March had something to do with term “alternative facts”:

The March for Science was held just a week prior to another major science-related march, the People’s Climate March that will take place in cities across the world on April 29, 2017.

Hundreds of satellite marches were held around the world on every continent except for Antartica. In D.C., the event was headlined by Bill Nye, Mona Hanna-Attisha, and Lydia Villa-Kmoaroff who, along with other well-known activists in the science community, presented a series of speeches complemented by “teach-ins,” educational sessions that covered topics from climate change to endangered wildlife.
