I have always been a big supporter of going green and recycling. I remember when I was in the fifth grade our Science teacher took us to McDonald’s so we could protest their use of Styrofoam containers for their big macs! So, yes, that seed was planted early!
My kids are also big into recycling…they are also very creative and recently started making these bracelets from pop tabs. 
You can find a good tutorial HERE. I think they are so great. Very funky.
A few other things we do to recycle, reduce, reuse:
1)we try to separate our trash…taking aluminum, cardboard, newspaper, glass, and plastic containers to the local recycling center.
2)we donate our toys and clothes to charity when we no longer need them…we also shop thrift stores and garage sales! We only buy new if we have to!
3)we walk as often as possible…to the park, the library, the gym, and school. We love to take walks
4)we USE our library…we have lots of readers in our house and we are always checking out new things to read!
5)we have lots of house plants around to improve our air quality, and we try to plant a garden every year. This year we are planting tomatoes, green beans and strawberries! We love to feed the birds too!
6)we use reusable grocery bags as often as possible, and on the chance that I forget them, or I don’t bring enough and we get plastic grocery bags, we use the plastic bags to line our small trash cans instead of buying trash bags.
If you stop and think about it…there are a lot of things we just do naturally every day that help to keep our world cleaner, and our lives healthier. And, if you’re not already doing these things…then just start today! Its not so hard if you take it one small step at a time! and I wouldn’t get too discouraged, the earth is like our bodies…in that, it has the ability to repair and rebuild itself…and any little thing that we can do to help will make a huge difference! Good Luck!
