The scarcity of building materials is threatening the health of some communities and could force tens of thousands of residents of communities across California and other states to leave their homes, according to a report from the U.S. Environmental Protection Agency.
The report by the agency’s regional office of health says the “Casa building material shortage is exacerbating and threatening to exacerbate health impacts, including health care, housing, and other social services.”
In some cases, it says, the shortage has led to the displacement of more than 2,000 people.
“The lack of building material is also contributing to the health risks of climate change, air pollution, food shortages, and water pollution,” the report says.
As of last week, the state of California reported that more than 1,600 structures had lost their building materials due to the shortage.
California has one of the nation’s highest building materials inventories, with the state estimating that it could need to produce more than 9.4 million tons of the material per year to meet demand.
The state, which has the third-highest concentration of construction materials in the country behind the states of New York and Texas, relies on California’s cement and limestone quarries for building materials.
But the shortage is worsening, with California building materials shortages hitting the hardest in the state’s San Joaquin Valley, where the shortage was particularly acute.
In 2015, the California Department of Water Resources reported that water-supply restrictions in the area forced about 1,200 homes in the region to close.
By the end of 2016, the department estimated that it had lost nearly 2,500 homes due to a shortage of building building materials in areas near the San Joab river.
And in January, the Los Angeles Times reported that the Los Gatos and San Francisco areas were the hardest hit by the shortage, with more than 8,000 homes lost due to construction shortages.
According to the report, the lack of construction building materials could also be affecting the health and wellbeing of the residents.
A lack of access to building materials can lead to problems such as heat and water damage, mold, dust and other environmental contaminants, according the report.
Casa materials, which include cement, limestone, and concrete, can be expensive and require a lot of maintenance, the report found.
More than 30 percent of California homes are in need of building supplies, and the shortage of materials has led some people to flee to California’s cities to avoid the shortage in their own communities.
