Everyday it's there waiting, from offers and fliers to coupons and catalogs. It's mail from thousands of different senders, but most know it by one name -- junk.
It all adds up to around 100 billion pieces of junk mail to American households each year. If you lined up all those envelopes end to end, they could circle the earth around 540 times.
So what happens to all that mail?
Statistics show in the U.S., about 6.5 million tons of junk mail is thrown in the trash each year.
The amount of trees wasted is staggering. According to DoNotMail.org, it takes more than 100 million trees to produce the junk mail that goes out in America each year. To get that many trees, you would have to wipe out the entire Rocky Mountain National Park every four months.
Environmentalists say that even though most people don't know about it, there is something you can do. The Direct Marketing Association takes requests to unsubscribe. You can visit their website by clicking here.

"We realized that [if] we could connect the consumers with those companies and let consumers tell those companies if they did or did not want their mail, we could save a lot of waste," said Chuck Teller, President of CatalogChoice.org.
The opt out service can also save a lot of money for companies sending out mail that never gets read, and for the communities who have to deal with the trash.
"It is so much more efficient for everybody... the consumer, the company, and the local community to stop waste at the source," said Teller.
It also stops the hassle, for households who would rather not get what they consider junk in the mail.
