Topic Sentence: Counterclaim Introduction
Some people may say that freshwater is not essential for biodiversity, arguing that certain species can adapt to changing water conditions.
Evidence:
However, studies show that freshwater ecosystems, like rivers and lakes, support about 10% of all known species, including many fish, amphibians, and plants that rely specifically on these habitats.
Explanation:
This evidence proves that freshwater is crucial for biodiversity because many species depend on it for survival and cannot thrive without it. Losing freshwater resources can lead to diminished populations and even extinction of these species, ultimately harming the entire ecosystem.
