Must-Have Eco Travel Guides

I've been dreaming about travel lately, and have been planning a few trips to Copenhagen, London and Paris. Luckily I came across a great new site with tips for green travellers such as myself on Strawberry Earth (a great resource site for all things cool+green): Very-Eco are eco-friendly travel guides, and they have tips for cities like London and Paris, which are just up my alley. I also recently discovered on Strawberry Earth's website that there are a host of Dutch city "green" guides, called Good & Green Guides - they even have one for Rotterdam! How did I miss that?!! Also, if you're travelling in Europe, or even in NYC soon, there are a host of good eating guides (mostly vegetarian, but they tip you off to organic/bio places too) available here. When in NYC, I absolutely lived by my Vegan Guide to NYC which gave me the ins and outs of all the vegan places to eat in all the boroughs. So what are you waiting for? Get to (eco) travelling!
