In their wordsVerbatim, exactly as submitted

“We must make our state healthy again. We must prohibit the polution of our skies with cloud seeding and sun dimming or whatever else it may be called. We must lessen the pollution of electomagnetic frequencies.…”

— Kathleen Moynihan, Brooklinesupports

“Clean NH skies by eliminating geoengineering in NH Please support HB764. We did not consent to the poisoning of our skies. The air we breathe is sacred. We deserve to breathe clean air.”

— Christyanna Umenhofer, Goffstownsupports

“Long term effects of cloud seeding are unclear, and potentially more hazardous than risks the technology is meant to address.”

— Nicholas Gilligan, Starksupports

“This proposed legislation reflects bad policy on the part of conspiracy theorists who don't understand science, and exemplifies the extreme need for critical thinking and STEM/STEAM literacy in our schools.”

— Jess Gerrior, Durhamopposes

“It’s a shame that this bill is being heard by the “science and technology” committee. This stupid bill is based on bat shit crazy conspiracy theories. It doesn’t deserve a hearing.…”

— dan Williams, Concordopposes

“There are already penalties in place for unauthorized cloud seeding. This bill would add a price tag of $500,000 to $1,000,000 for measures to counter activities that don’t exist in N. H. Please oppose this costly and unnecessary bill.”

— Janet Lucas, Camptonopposes
