A new study has suggested that America’s coffee habit is harming the environment.

Researchers have discovered that because the human body is unable to consume all of the caffeine, the leftovers are expelled in urine and have made their way into rural streams.

Studies have found that, when exposed to caffeine, animals becomes stressed and are unable to protect their DNA for being genetically mutated by the stimulant.

CAFFEINE IS BAD FOR THE ENVIRONMENT 

Researchers have discovered that because the human body is unable to consume all of the caffeine, the leftovers are expelled in urine and have made their way into rural streams. 

A study investigated how the stimulant affects the creatures living in the area.

The team found that near-shore mussels who live in both Oregon and the San Diego area were forced to use energy to make a protein that protects its DNA when exposed to low levels.

However, those found in high level areas stopped producing the protein and were at risk of genetic mutation.

‘They get so stressed out at a cellular level that they can’t protect their DNA with this protein,’ Granek said.

Experts have previously known that the caffeine expelled by humans made its way to sewage systems in urban areas, but new findings have found that the stimulant has reached rural streams.

A team from the San Diego Regional Water Quality Control Board had found traces of it in the wild, knowing that there are no natural sources of caffeine in North America, they were force to conclude that it came from humans.

Researchers collected samples from 2008 to 2015 from streams in the San Diego Region and parts of Orange County, reported Matt Weiser with UPI.

The samples were taken from both raw sewage and treated waterwater in urban areas, in addition to some in streams in remote areas.

After analyzing the water, the team had conclude that the urban water had traces of caffeine – a result that was expected.

Samples from untreated sewage had between 0.052 and 8.5 micrograms per liter and those form septic systems ranged from 0.029 to 1.19 micrograms per liter.

However, researchers were surprised when they discovered that the streams had also tested positive – the samples ranged from 0.032 to 0.662 micrograms per liter.

Other than caffeine, traces of other human waste was also uncovered, such as viruses, pathogens and pharmaceuticals and personal care products were also detect in the samples.

‘No caffeine was detected in samples collected from the sites with little to no known recreational use, and caffeine was detected in all but two of the samples collected from sites with known recreational uses, such as hiking, fishing, or horseback riding,’ the team explained in a press release.

The team had determined that the potential caffeine sources included ‘leaky sewer lines, poorly maintained septic systems, food waste or beverage containers from trash receptacles or littering, recycled water used for irrigation, and storm‐water runoff.’

In a similar study, researchers examined the coast of Oregon where they detected 45 nanograms per liter along coastlines and just 9 nanograms per liter in urban areas.

‘That indicates poor-performing septic systems in rural areas, Elise Granek, the study’s lead author and a marine ecologist at Portland State University, told UPI.

A third study, investigated how the stimulant affects the creatures living in the area.
