The United States has more than 6 billion toilets in use, and nearly half of them are in urban areas, where residents don’t have access to clean water.

And many Americans have been complaining about the lack of soap and water.

But one product that can help reduce that problem is toilet paper.

A recent survey by the National Conference of State Legislatures found that in some cities, the prevalence of toilet paper has decreased by more than half since 2000.

The survey found that one product, toilet paper that is “smooth, water-resistant, and eco-friendly,” has the potential to reduce water consumption by up to 10% a year.

The results are based on a survey of 6,000 households in six states over two years, which included an analysis of household data collected from 2008 to 2017.

The researchers compared the rate of toilet use with the rate in the survey year and the average rate of use per household.

The study found that toilet paper in urban households was used less than it was in rural areas.

According to the researchers, in urban communities, people are spending more on toilet paper, which results in higher water consumption.

That means that people who live in the most water-dependent areas are spending less on toiletry and waste disposal.

“The people who have a more water-intensive lifestyle tend to be people who are also consuming more water,” said Dr. David W. Wiedenmeier, the director of the University of California, Davis Center for Environmental Health.

“That may be because of their increased consumption of food, water, and tobacco, and may also be due to lifestyle factors like a diet high in processed foods and sugary beverages, which can make them more susceptible to water-borne illness and other water-related health problems.”

“In urban areas,” Wiedanmeier said, “people tend to spend more on waste disposal.”

According to Wiedmann, the study’s findings suggest that it’s possible to reduce toilet paper use in a few areas.

“It’s definitely possible to have an effect in the cities, but we can’t tell how much,” Waidanmeier told HuffPost.

“We think that we can do something in terms of reducing waste and water use in these areas that could be beneficial.”

He also noted that while some communities are already using toilet paper to help alleviate water scarcity, the amount used in urban environments is still far below that of rural communities.

“A lot of the rural areas use less toilet paper than urban areas do,” Widenmeier said.

“I think the cities will get a lot more use than the rural communities, and then there will be some of that wasted.”
