It seems to me that living in an Eco-conscious way is important for a Pagan....  The Earth playing such a vital role in our beliefs, it would be sacrilegious not to really....  Now I'm not suggesting we all run out and make mud brick houses, without amenities, and live in non-consumerist solitude... (I can afterall not live without my computer!)  But there are choices we can make that can help live a more eco-friendly lifestyle, without too much strain.   Sometimes it can be easy to get caught up in convenience of modern society, with our single use products and disposable attitude, but we of all people should take more care.  Unfortunately too the nature of Witchcraft tends to use single use items, like candles, a lot.  But with a bit of thought we can have our Witchcraft and not have to sacrifice the Earth. Eco-friendly ideas for everyday living For Pagan stuff, read on...

Candles
Burning candles is actually not so great for the environment - for a start most candles are petroleum/parrafin based, plus you have the fact they burn oxygen... Since most of a Pagan's Ritual and Spellwork includes using candles, there are a few things you can do to have a lower impact.

• Use fewer candles - Use the ones you need, but less candles just for mood
• No Single Use Candles - Rather than using a new candle for each ritual/spell - cleanse and consecrate the same candles.  Even if you keep a box with compartments or some other means for storing candles, so you can keep track of which ones have been used for what, and use the one candle for all healing spells for example.  Or melt the candles down and use them to make other candles.
• Don't bury - candles are wax and are not going to break down quickly, so it is better to reuse them that to leave them discarded in the ground.  If you must bury a candle, perhaps return after a while to dig it up and reuse or melt it down again.

Organic
While not always possible.... where you can, try to buy organic herbs, oils and other ingredients.  These are grown without the use of pesticides and are much better for the Environment.  When having a simple feast, try to incorporate organic foods, and homemade foods, rather than buying prepackaged ones.
 

Earth Hour

One thing that really urks me about people's attitudes to Earth Hour is that "it does no good, so I won't bother" - worse when it's from people who believe it's not doing enough, so they won't bother.   It is one step, and if you can inconvenience yourself for an hour (better yet, do what I do and turn everything possible off, for a couple of hours!), then it does make a difference.  Consider it a modern Pagan Sabbat - it's a night where we are encouraged to do something for the Environment - something on a global scale...... Seems Sabbat-worthy to me!  Maybe get some Pagan friends together and have a ritual based on the Earth to celebrate.
