Artists address environmental issues through their work by creating art pieces that raise awareness about environmental concerns, convey messages about the importance of sustainability, and advocate for positive change. They may use various mediums such as paintings, sculptures, installations, performances, and digital art to explore themes related to climate change, pollution, deforestation, and other environmental challenges. By showcasing the beauty of nature, highlighting environmental degradation, or proposing solutions to pressing environmental issues, artists can inspire viewers to reflect on their relationship with the environment and take action to protect it.
