The Lorax: The Last Tree Falls
Science → Environment → Effects of Deforestation
The Lorax confronts the Once-Ler, who has been cutting down Truffula trees to manufacture Thneeds. The two witness the cutting down of the last Truffula tree, marking an end to the viability of the Once-Ler's business. The lack of trees also adversely affects the environment, as is evident by the coughing of the residents of ThneedVille and the migration of all the wildlife.
