As we enjoy the July 4th fireworks this year, think about what it took to provide the show. In 2016, more than 268 million pounds of fireworks were consumed in the U.S., according to the American Pyrotechnics Association.
Fireworks are fueled with black powder and use various metals to create the special effects and vivid colors. Potassium nitrate (aka saltpeter) comprises 75 percent of black powder and is primarily mined in Canada, with some produced in New Mexico and Utah. Flashes and bangs are produced by aluminum powder. The largest producers of aluminum ore are China and Australia. Sparks are produced by iron filings. U.S. iron ore is mostly mined in Michigan and Minnesota.
As for the brilliant colors, greens result from barium, which is primarily mined in China. Copper is mined in Arizona, Utah, New Mexico, Nevada, Montana, Michigan and Missouri, providing the blue colors. Reds are created by strontium, mined mostly in Mexico. Yellows are created from sodium nitrate, which is mined mostly in Chile and Peru. Silvers are produced from titanium, zirconium and magnesium. Titanium and zirconium are mined in Florida and Georgia, with significant quantities imported from Australia, South Africa and China. Magnesium is mined from saltwater in Utah, California and Delaware, with significant quantities imported from China.
So as you watch the fireworks this year, remember they come from mines all over the world. If you like the fireworks show, thank a miner!

IMMIGRATION
Of course we should abolish ICE, open borders, sacrifice eagerly
The question of whether or not to abolish Immigration and Customs Enforcement shouldn't even be a question at all ("Mpls. marchers: Reunite parents, kids," July 1, and Readers Write, July 3). ICE needs to go, and there doesn't need to be a replacement for this terrorist organization. President Donald Trump uses ICE as a political weapon.
I believe in all sincerity that there should be no borders at all. Those who want to come here should be able to. Everyone's welcome. True, most of the new immigrants are poor and bring nothing but their children and the clothes on their back. America is a wealthy country. We can pay for them by taxing the upper 10 percent at a 90 percent tax rate. Also, Social Security and Medicare payments can be slashed, with that money also going to the refugees. America can suck it up. Its people don't need all that they have.
Another idea is to find out who lives in homes with extra bedrooms. Those who have extra rooms should allow refugee families to move into their homes. There is no better way to show the world how kind, generous and accepting Americans are than by sharing our homes and wealth with those who are less fortunate.

'GOOD GERMAN,' 'GOOD AMERICAN'
Freedom of speech and response; the weight of events and words
The " 'Good German,' 'Good American' " commentary (June 25) generated some well-considered replies to a complex issue that may never be fully understood. One Readers Write response, in its final paragraph, could raise a certain level of discomfort in the minds of many journalists. I draw a parallel to the accused shooter in the deaths of five people at a newspaper in Maryland, because that attacker, as reported, had a long conflict with the Capital Gazette.
