US president Donald Trump completed 100 days in office today (Apr. 29), and he was greeted by more than 200,000 people marching to the White House in Washington, DC and thousands of others marching in cities around the country. The People’s Climate March was designed primarily to resist Trump’s views on the environment. Unlike its predecessor, the March for Science held last week (Apr. 22), the climate march did not claim to be non-partisan.

As with any large protest, there was no scarcity of witty and incisive protest signs. Quartz has curated a few of the best examples from marches held across the US.
