I always remember this film as "The Last Tree" regardless of its real title. Maybe because it's about the last tree, so, I considered the title as "The Last Tree".
This film is one of those films which have important message. Tree is one of the most important things to have in this world. Trees make oxygen and prevent the environment from getting hotter. Chopping trees can make you money of course, but at the same time, it makes the environment worse than before. Nowadays, in some countries, the weather is so hot, hotter than past 2 or 3 years. Mostly, it's because there aren't more trees. People are chopping them to sell. Some people make things and sell them like in the film. Some people are just selling the whole thing. Trees becomes less and hence, making the weather hotter and hotter. So, if we want to stop this condition, we have to protect the trees and plant more trees. Otherwise, it will become exactly shown in this animation.
Although this film has the greatest and most important message, it also have the biggest flaw. The trees in this film look weird. The trees from the real world are not like them. In the other words, the trees from the animation aren't realistic. It makes the viewers feel strange.
Overall is that this film is also a great film. It's one of those films you can't miss. Everyone must watch this one at least one time and learn a lifetime lesson.
