- Reduction of diversity of aquatic species
Nature
Catchment changes, together with alien plant and animal invasions and domestic, agricultural and industrial pollution are among some of the primary mechanisms for biodiversity loss in aquatic areas.
Incidence
Between 1970 and 2002 the biodiversity of global freshwater ecosystems declined in the region of 55 per cent.
Counter-claim
Frankly, the so-called “loss of freshwater biodiversity” is vastly overblown. Rivers and lakes have always changed, and species come and go as part of nature’s cycle. Human needs—agriculture, industry, and urban growth—are far more important than worrying about obscure fish or insects. Resources should be focused on real issues like economic development, not on preserving every single species in a pond. The alarmism around freshwater biodiversity loss is simply misplaced.
