Phathu said: “The piece reflects my community, the homes they live in and how we can improve those standard of living while healing the earth. I believe for us to have a future we want, we need to go back to the root and start from the beginning. I want a future where people have access to renewable energy, using less fuel and more Eco-friendly cars. More locally grown food, where households have access to food and water. I want a future where we invest in young people no matter, their gender or race.”
