Despite the ecological lessons we've learned about plastic bottled water, it's still growing in popularity, with sales skyrocketing across the country. Only a small percentage of plastic bottles are actually recycled, and it's not necessarily better for you to drink bottled water, either. If you're unsure about making the switch to drinking filtered tap water, maybe this other green fact will change your mind: You'll save about $1,400 a year by ditching bottled water. Move to tap water, and you'll spend less than $1 for the whole year's worth of drinking water. Make 2015 the year to go bottleless.

Many of us like to buy suet balls or birdseed encapsulated in mesh bags, which helps keep the birdseed together when you hang it outside. While our feathered friends can get a healthy meal or snack from these, there is also a chance they can get entangled in the mesh. When the suet or bird food gets low, it creates air pockets around the mesh bag. This can lead to birds digging deeper into the bag, which can lead to their legs and beaks getting trapped and entangled. Stick with traditional methods that involve loose feed instead.

If you bought a bag of baking flour, say, more than a year ago, there's a good chance that flour has gone bad. Pull it out of the pantry and give it a smell. Does it smell rancid? If so, it's a good idea to toss it. But before you do, go grab the stacks of playing cards you have around the house. Throw the cards into a bag and cover them with the old flour, then seal and shake. The flour will coat the cards and take away the dirt, grime, odors and oils to make the cards fresh and clean. And then take all of the old flour and sprinkle it in the yard, it's biodegradable, and your lawn will love it.
