A new art show called 'Roots of Cool' at Descanso Gardens in L.A. brings attention to the role of trees in mitigating climate inequities in urban environments. The focus of the show is on the contribution of trees, particularly their ability to provide shade, in enhancing the health and well-being of urban communities. Through the lens of all-women artists, the exhibition sheds light on the importance of urban green spaces and their impact on creating healthier living conditions, especially in the context of rising temperatures and climate change.
