The document discusses the choice between conserving biodiversity or not. It notes that human activities like land reclamation are threatening biodiversity by disrupting ecosystems. However, not taking these actions would limit satisfying growing human needs. The document argues we should conserve biodiversity for several reasons: every organism supports ecosystems that provide food; once lost biodiversity can never be replaced; and environmental changes affect both nature and humans. It provides ways to conserve like being careful not to harm biodiversity, preventing pollution, and avoiding driving species extinct since all life is interconnected. The conclusion is that with so many reasons to protect biodiversity, we should make an effort before it's too late.
