What is the cause of lake Victoria before the disaster?

Answer 1

Before the disaster, Lake Victoria faced significant environmental degradation primarily due to pollution, overfishing, and invasive species. Agricultural runoff introduced harmful nutrients, leading to eutrophication, which degraded water quality and harmed aquatic life. The introduction of the Nile perch disrupted the native fish populations, impacting the local fishing industry and biodiversity. These factors combined created a precarious ecological balance that contributed to the lake's decline.
