BBC Earth is proud to present a special collection of programmes that showcase the beauty of the world that we live in, but also highlight the fragile nature of its existence. Our new Eco Season will take you on a journey of discovery and deeper understanding of the world we live in and how we can protect it.

This landmark season of programming is brought to you in association with One Tree Planted, a non-profit organisation that is supporting global reforestation. To celebrate this Eco Season, One Tree Planted are planting 100,000 trees across regions such as Europe, Asia, and South Africa. To track the charity’s tree planting activities and find out more about the organisation, head to their website.
