Black spheres with a distinctive odor have been discovered on the beaches near Sydney, Australia. Initially, they were thought to be remnants of an oil spill; however, research revealed that these spheres are made from feces and more. They are referred to as "fatbergs" and are typically found in sewage systems, composed of waste materials.

Detailed testing revealed that these black spheres contain a mixture of substances that alarmed scientists. In addition to human feces, they found recreational drugs, industrial chemicals, cooking oil, and diesel fuel. Although the composition is now known, the source of these spheres remains unclear. Experts from the University of New South Wales (UNSW) stated that while the composition aligns with anthropogenic waste, it is still unknown whether they originated from local sewage systems, were dumped from boats, or resulted from stormwater runoff.

The presence of such fecal spheres indicates water pollution around Sydney. Authorities have already closed the beaches where these fatbergs were found and have begun cleanup efforts. The investigation into the origins of the fecal spheres is ongoing.
