Given the task definition and input, reply with output. In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: disagree or agree. Classify the comment as disagree if it is likely to raise a certain level of public disagreement, whether healthy or unhealthy. The disagreement can be due to toxic content (for example, disrespect, identity attack, insult, and threat), controversial content, misunderstandings, or conflicting opinions. Classify the comment as agree otherwise.

Comment: Sustainability?
What is sustainable about deforestation?
The amount of useful soil on Canadian land is quite thin, compared to more southern climes. When you take a tree and ship it fifteen hundred miles south, you have also taken the nutrients that built that tree with it.

By sustainable, are you suggesting that Canadian foresters take a tree and leave an equivalent amount of fertilizer? No? Then explain further this "sustainable" thing...
