Welcome to Learning English, a daily 30-minute program from the Voice of America.

I'm Ashley Thompson.

And I'm Mario Ritter Jr.

This program is designed for English learners, so we speak a little slower and we use words and phrases

especially written for people learning English.

On today's program, Anna Mateo tells about a Brazilian artist whose subject is climate change.

Brian Lynn has an unusual fish story from Cambodia.

Then learn more about the most common prepositions in English on everyday grammar.

And finally, the lesson of the day.

But first...

Brazilian artist and activist Mundano recently used some unusual substances to paint a picture on a building in Sao Paulo.

The paint included materials such as ash and mud

collected from natural disasters.

Mundano created the mural to highlight the issue of climate change.

Extreme weather events have been causing destruction highlight the issue of climate change.

Extreme weather events have been causing destruction across Brazil.

The mural is very large, over 30 meters high, and 48 meters wide.

The artist used ash from wildfires and mud from floods.

His painting shows the gray remains of trees on a brown land so dry it is cracked.

The picture represents the deforestation and severe drought in the Amazon rainforest.

The mural also shows indigenous activist Alessandra Korape, wearing a circle of flowers around her head. She holds a sign that says, stop the destruction.

Hashtag keep your promise.
