Blue Ollis is a popular sustainability blogger and vlogger who became a full-time eco-traveller when she left her city life behind in the spring of 2022 to travel the Earth (at the time of writing she is in Colombia having spent time in Spain and Portugal). She blogs about her travels on her eponymous website and her popular YouTube channel, explaining how she is travelling alone and sustainably on a tiny budget. She has a combined audience of over 110,000 souls across YouTube, Instagram, and TikTok, and that number is growing all the time.

Ollis was born in London and also spent time living in California as a child before returning to London. Her articulate passion for everything from Zero Waste living to animal rights to mindfulness and self-love made her a natural blogger, and she soon built a reputation as an ethical influencer of note. She began her YouTube channel back in 2011, and since then, her audience has grown with her, following her journey as she simplified her lifestyle, became self-employed, stopped wearing bras, grew her hair, got a vegan tattoo, and ultimately, decided to sell most of her possessions and embrace a nomadic lifestyle, travelling the world as cheaply and as eco-consciously as possible.

As well as her blog content, Ollis is the author of three digital books: My Essential Vegan, My Essential Meal Plan, and The Guide to Sustainable Living. She has also designed a journal, Journal to Self. All are available from her website. She will also soon be offering virtual courses on sustainable living.
