Earth Day here in Sussex

Each year on 22 April, Earth Day brings together more than a billion people worldwide, making it one of the largest events on the planet. Since it began in 1970, it has helped drive major environmental protections and continues to highlight urgent challenges, from climate change to biodiversity loss.

But while Earth Day operates on a global scale, its impact is ultimately shaped by what happens locally.

Why it matters in Sussex

At home we feel many of these environmental challenges keenly: from flood risks to water pollution to a decline in local wildlife species. Tree cover in parts of the UK remains relatively low, and access to quality green space is decidedly uneven. Because of this, schools and communities are increasingly looking for ways to respond, whether that’s improving outdoor learning, supporting wildlife, or creating spaces that benefit wellbeing.

This is where practical, local action matters. Planting and caring for trees isn’t just a symbolic gesture; it’s a long-term investment in healthier, more resilient communities.

What it looks like on the ground

For Tree Action, Earth Day is a chance to amplify the messages that are at the heart of our work: to connect young people with nature and their environment and give communities the opportunity to make a practical difference.

Over the past few months, we’ve been working with schools across Sussex to transform their grounds, turning underused spaces into orchards and green areas that children can learn from and enjoy. At Seaside Primary, pupils recently planted a mix of apple, pear, cherry and plum trees as part of a wider plan to green their school site.

Alongside this, we’re supporting communities and volunteers to get involved directly, whether that’s helping plant trees in Lancing Ring Woodland, maintaining young trees at Southwick and Adur recreation grounds, or planning future projects.

None of this work can happen on a single day, but Earth Day helps bring it into focus. If you’re looking to take part, this is a great time to connect with what’s already happening.

What you can do

Earth Day is a chance for everyone to get involve in any way they can. No matter how small an action you take, each one will make a difference. Here are some ideas for you to celebrate Earth Day in your own way.

• Join a beach clean – along the coast in places like Brighton or Worthing, regular clean-ups help tackle marine litter and protect wildlife
• Explore the South Downs – take a walk or cycle and reconnect with one of Sussex’s most beautiful landscapes
• Get involved in a community litter pick – many neighbourhood groups organise clean-ups in parks, streets, and green spaces
• Plant for pollinators at home – even a small garden, balcony, or window box can support bees and other insects
• Shop and eat locally – Sussex has a strong network of local producers, helping reduce food miles and support sustainable farming
• Use greener transport where you can – walking, cycling, or taking the train along the coast instead of driving
• Volunteer your time with us! From planting days to aftercare, our local projects rely on ongoing support

Earth Day may be global, but its success depends on consistent local action. For Tree Action that is already underway and growing, one project at a time.
