Hamburg (AP) - The rapper Smudo and the pop singer Sasha have planted in the new "Fame Forest" ("Forest of the Famous") in Hamburg first trees for a good cause.

"It is said that in life one should build a house, father a child and plant a tree. I have completed this today », said Sasha on Wednesday the German Press Agency.

For Smudo, a member of the hip-hop band The Fantastic Four, it's been the first tree he has ever planted: "Everyone should pay attention to their carbon footprint - fun does not mean CO2 consumption at the same time," the rapper said. Smudo runs "green" motorsport with his own racing team, using fuel that is partly made from biowaste.

In the future, every artist will be able to plant a tree in the "Fame Forest", which will perform in Hamburg's Barclaycard Arena. The trees would then be provided with a sign with the name of the artist.
