The Nature and Art of Fireworks

The World

Every year we celebrate America’s independence by sending combustible cocktails called fireworks into the sky. And every year some environmentalists object. This year, a lawyer representing a coastal conservation group in California won a suit that would force locals wanting to light-up to first file an environmental impact report with the state. It nearly kept the town’s fireworks show grounded. Living on Earth’s Ike Sriskandarajah looks at the chemistry of what goes up and what comes down.

Do you support journalism that strengthens our democracy?

At The World, we believe strongly that human-centered journalism is at the heart of an informed public and a strong democracy. We see democracy and journalism as two sides of the same coin. If you care about one, it is imperative to care about the other.

Every day, our nonprofit newsroom seeks to inform and empower listeners and hold the powerful accountable. Neither would be possible without the support of listeners like you. If you believe in our work, will you give today? We need your help now more than ever!
