Japanese pop star AYAKA called on the crowd at the Tokyo LIVE EARTH concert to help save the world. The star, part of the line-up at the Japanese event, has already started changing the way she lives in a bid to cause less damage to the environment. Speaking at the concert, she said, "We can start helping by doing something small. "I started to carry my own eco-bag so I don't have to use plastic grocery bags, and use my own chopsticks instead of disposable ones."
