This store provides embarrassing bags to stop shoppers from using plastic
Grocery store owner David Lee Kwan initially hoped that a fee on single-use bags would discourage his customers from using them.

Concrete could be made cheaper, stronger, and greener using old glass
Although glass is thought of as being relatively eco-friendly because it's recyclable, the fact is that a lot of it doesn't get recycled – this is particularly true of small fragments, that are too fiddly to sort. Now, however, scientists are suggesting that glass waste could be used to make Read More...
You have to see these portraits of farm animals that were allowed to grow old
When you see a really old dog, it can make you feel all fuzzy inside. But have you ever seen an elderly farm animal?
