It could be an outdoor activity because of season and location in Yilan, Taiwan. Enjoy to follow them and keep an eye close on the fish they are trying to save and the lake they are trying to green. People carry hand-made-fish-ladder and showing how they tried to assembly next to a small creek, they look so careful, fine and smooth.
Also, fish seems accepted all that and play around in front of camera all these days. Visitors like to watch all the process and experience themselves, tree, bird and water could speak every word and everything loud.
A small island on earth that could not get more attention in public, and it is warm and meaningful this way.
