What's often lost in the political debate is that illegal immigration to the U.S. is on the decline. The number of undocumented immigrants in the U.S. peaked during the mid-2000s and has continued falling.As a result, the number of babies born in the U.S. each year to undocumented immigrants is also declining. After steadily increasing since the 1980s, this figure peaked in 2007 at 370,000 births. Since then, each year has seen fewer births than the previous year, according to the Pew Research Center. Even as the overall numbers have declined, as a percentage of total U.S. births, this group has seen its share increase. The nonpartisan group says the most recent data is from 2014."This trend matches a number of other trends that we've seen among unauthorized immigrants," said Mark Hugo Lopez, director of global migration and demography research at the Pew Research Center. "Generally speaking, that population has been in decline." 943

What we're looking at: Erupting volcanoes spew hazardous sulfur dioxide gas. If conditions are right, that gas and other pollutants can settle with moisture and dust to create a haze called volcanic smog, or "vog," with tiny sulfuric acid droplets.If it rains when it's voggy, you get acid rain.What causes it: We've had vog already, but mostly south of the island over the ocean, because trade winds have largely been keeping it away.But the winds are expected to calm down Thursday and Friday, possibly allowing the vog to settle over more of the island.It should rain over the Big Island on Thursday into Saturday. The vog's sulfuric acid droplets would fall, too -- thus, acid rain.How it impacts people: Vog seems to be the more immediate health concern. At higher concentrations, vog can cause headaches and irritation to the lungs and eyes, the University of Hawaii at Hilo saysHigh levels of acidic particles in vog "can induce asthma attacks, especially in adolescents, and can also impede the ability of the upper respiratory tract to remove other potentially harmful particles," the USGS says.For people with asthma and other respiratory problems, "the effects are much more serious, causing a tightening of the airways in the lungs and making it very difficult to breathe," the university says.But it adds: "There's been no clear evidence that vog causes lingering damage to normally healthy individuals."How acid rain affects human health is more complicated.Walking in acid rain or swimming in a lake affected by it "is no more dangerous to humans than walking in normal rain or swimming in non-acidic lakes," the Environmental Protection Agency says.But acid rain can contaminate household water supplies by leaching metals from building and plumbing materials, the USGS says. That includes rooftop rainwater-catchment systems that Hawaii residents use for drinking water. 1912

We will be working very, very hard on that horrible, horrible issue that took place last week in Florida, Trump said at an event on Tuesday. "We're working very hard. We're going to come up with solutions. It's been many, many years, and there have been no solutions. We're going to come up with solutions." 307

Ralston, who has been teaching for more than 30 years, announced her bid last week in response to Representative Kevin McDugle's angry criticism of teacher walkouts."That's when I decided, 'Oh, we're coming. I'm doing this,'" Ralston told?CNN affiliate KOKH while she waited for registration to begin. She's running for McDugle's seat in District 12."I feel like we're showing the students what a free democracy is all about."Before the deadline ends on Friday at 5 p.m., dozens more plan to sign up. 624
