How does water pollution affect aquatic biodiversity?

Water pollution makes river biodiversity more vulnerable to climate warming. Polluted rivers with low oxygen levels are more susceptible to the harmful effects of climate change, according to a new study co-authored by MARS scientist Professor Steve Ormerod. … “First, at higher temperatures, water can hold less oxygen.

How can aquatic resources be protected and conserved?

One such option that has potential to protect freshwater environments from numerous threats is the use of freshwater protected areas (FPAs). FPAs are portions of the freshwater environment partitioned to minimize disturbances and allow natural processes to govern populations and ecosystems.

What are the negative effects of water pollutants on aquatic ecosystems?

Algal blooms can reduce the ability of fish and other aquatic life to find food and can cause entire populations to leave an area or even die. Harmful algal blooms cause thick, green muck that impacts clear water, recreation, businesses and property values.
