Thousands of people marched in Sao Paulo to pressure the Brazilian government to do something about the burning Amazon Rainforest. Here's what it looked like on the ground.

The demonstration began at the São Paulo Museum of Art, and art was a major feature in the protest. Here, kids paint to encourage preserving the Amazon Rainforest.

A young man held up a quote from Chief Seattle, a leader of the Suquamish and Duwamish tribes in the 1800s: "The Earth does not belong to man, man belongs to the Earth." The chief is the namesake for Seattle, Washington.

A group of young people held signs side-by-side. One reads, "Fire on racism, not in Amazonia."

People screamed words pro-Amazônia and anti-Bolsonaro. Late Friday night, the Brazilian president announced he would send the army to fight the forest fires.

The avenue filled up with people waving flags, signs, and banners.

This large sign reads: "Burn fascist, not forests."

Many police officers were also present during the protest.

Along the way, on the road Alameda Tiete, a wall was filled with protest words.

"Amazônia viva!" a woman wrote on the wall.

The protest was made up of different people, from different religions, styles, and cultures, but all with a common point: Protect Amazônia from everybody who doesn't care — including the Brazilian president.
