When Grandma says
What's the deal with fracking? It sounds more like a swear word.

You can say
It's actually dirtier than a swear word. Fracking is short for "hydraulic fracturing." It's a violent process where natural gas companies inject chemicals into the ground to dislodge gas deposits from shale rock formations.

It contaminates drinking water, pollutes the air, and causes earthquakes.

When Grandma says
Why aren't we drilling for oil in the Arctic? No one lives there.

You can say
Alaska Natives who live there would very much be affected by oil drilling -- especially when that drilling causes a spill. It's also home to the entire U.S. population of polar bears and is an important migration route for bowhead and beluga whales.

We don't need to open this irreplaceable area to drilling. Instead we should make our cars cleaner and more efficient, expand our transportation choices, and invest in clean energy.
