In some places, you can't buy a plot no matter how much money you have. As a result, cremation rates have risen fast. In 1950, if you suggested your grandmother be incinerated after she died, you'd probably be kicked from the family deathbed. But today, almost half of Americans choose cremation, citing simpler, cheaper and more ecological as reasons. I used to think that cremation was a sustainable form of disposition, but just think about it for a second. Cremation destroys the potential we have to give back to the earth after we've died. It uses an energy-intensive process to turn bodies into ash, polluting the air and contributing to climate change. All told, cremations in the US emit a staggering 600 million pounds of carbon dioxide into the atmosphere annually. The truly awful truth is that the very last thing that most of us will do on this earth is poison it.
