Final answer:
In the Lorax, the commons are represented by the Truffula Trees and the land they grow on. Before the Once-ler arrived, they were managed naturally, but after his arrival, the commons were destroyed, leading to negative consequences for the entire ecosystem.
Step-by-step explanation:
In the world of the Lorax, the commons are represented by the Truffula Trees and the land they grow on. Before the Once-ler arrived, the commons were managed naturally, with the ecosystem being in balance. However, after the Once-ler arrived, he began mass-producing Thneeds from the Truffula Trees, leading to deforestation and destruction of the commons. The consequences of the Once-ler's actions were faced by the entire ecosystem, including the animals and the environment, as they lost their homes and resources.
