About Tens of thousands  advocates of science and research took to the streets of New York on Saturday to promote greater understanding of science and protest against their work being compromised by proposed federal budget cuts.

The March for Science, with coincided with Earth Day, began with a rally at 10:30. An estimated number of over 30,000 people filled up at least a dozen blocks north of the Trump International Hotel at noon.
The March for Science festivities on Saturday included 'teach-ins' on the National Mall and parades in midtown Manhattan and hundreds of other cities and towns.

Marchers held aloft placards with slogans such as “Don’t hate, educate,” and “There is no planet B” as they sought to spread their message.

As the massive crowd walked down to Broadway and on to midtown Manhattan, chants of “Science makes America great” rippled down the street. A 2.5-kilometer stretch of Broadway was also closed to cars for the march.
Many of those active in the march were university students and teachers, as well as many who work at research institutions. Some dressed for the occasion in their lab robes while others sought to make their point clear by donning shirts coated with arithmetic formula.

March for Science is the latest in a series of national demonstrations staged since Mr Trump's inauguration nearly 100 days ago. Previous marches and protests have focused on a range of partisan issues, from abortion rights to immigration policy.

The event was initiated online by U.S. scientists in response to fears over the Trump administration’s policies. A budget proposal released on March 16 looked set to cut down funding on the departments of agriculture, labor and the environmental protection agency, while increasing the budget for the departments of defense and homeland security.
