Nice Anime opening song

i found the mp3 named flaco on my hard disk, probably one of my anime-crazy sisters downloaded it. i liked the song very much, so i searched for the anime where it was used as an opening.
The anime doesnt look as good a s the song, but its idea is nice: a boy who has a special power to turn any thing that he believes trash into trees! lool nice he might help our world with the waste & garbage problem and decrease pollution!
any way the song reminds me of the music used in the Prince of Persia 3D game. here's the song with the lyrics as a video. (make sure you learn all kanji in it! its useful ne!) (^_^)


and here's the Anime opening



soon i'll have more time to talk about anime! otanoshimi ni!(^_^)
