Take a look at those rolling hills! They stretch as far as a few soccer fields and measure about 50 feet high. Some look grassy. Others look muddy. Unlike normal hills, they shimmer in the sun. That’s because these hills are not made of grass and dirt. They are made of glass.

Phoenicia Glass Works Ltd. is a company in Israel. It makes a million glass bottles and containers every day. Many of those bottles and containers eventually hold Coca Cola, Pepsi, or olive oil. But each day, about 300,000 of them don’t turn out right. They come out of the ovens with defects. They are ground up and put into these glittering piles.

The ground-up glass does not go to waste. Workers shovel it up and throw it back into the factory’s ovens. They fire the glass into new bottles. Maybe you have drunk soda from a bottle that once sat in one of these glass hills!

When God gave us glass, He gave us a material that is cheap and easy to recycle. Every ton of recycled glass saves 1,330 pounds of sand. If you recycle one glass bottle, you’ve saved enough energy to light a 100-watt lightbulb for four hours. No matter how much you use it, its quality will stay good. When you recycle it, no part of the glass is lost. You can keep recycling it over and over again!
