Nature’s Pharmacy: Why Earth Day 2026 is Your Business

Dear all

Monday 20th April marked the anniversary of the Deepwater Horizon disaster in 2010, when an explosion on an oil rig in the Gulf of Mexico led to the largest marine oil spill in history, causing catastrophic damage to marine life and coastal ecosystems – a stark reminder of how fragile our environment is and the importance of Earth Day, which took place on Wednesday (22nd April). The theme for this year’s Earth Day is ‘Our Power, Our Planet’, representing a call to arms for people around the world to take notice of the threats to our environment and do something positive to help. However, campaigns like this can often seem abstract and remote from our daily lives in Brentwood, in the UK, and even in the Western world. On Monday, I shared with our students just one of the many ways in which the natural world affects everyone, no matter where they live.

One of the most vital resources we have is our forests, which have stood for centuries as humanity’s first pharmacy. You might not realise it when you go to the pharmacy or open a medicine cabinet, but many of the treatments we rely on daily come directly from trees. For example, aspirin, which has long been a first response when we have a headache or a fever, has its roots in the white willow tree. Ancient Greeks and Sumerians used willow bark for pain management long before scientists isolated the ingredients to create the pills we use today. Forests also provide the front-line defence against some of the world’s deadliest diseases:

• Malaria: Quinine, the first antimalarial drug, was discovered in the bark of the cinchona tree in the Andes. Later, the Nobel Prize-winning discovery of artemisinin came from sweet wormwood.
• Cancer: More than 65% of cancer medications originate from plants. This includes paclitaxel, derived from the Pacific yew, which stops cancer cells from dividing, and treatments from the “happy tree” (Camptotheca acuminata), used to fight breast and lung cancers.

In fact, around 11% of the World Health Organisation’s ‘essential’ drugs originate from flowering plants, while it is estimated that 50,000 medicinal plant species form the basis of more than half of all medications globally.

When we hear stories of deforestation – the industrial-scale clearance of trees for building materials, fuel, or to create space for agriculture, grazing, mining or human settlement – they can sometimes feel distant from our daily lives, but maybe less so when we connect our forests to our medicine cabinets. Up to 20% of medicinal plants are at risk of extinction because of habitat loss, and once this biodiversity is lost, it won’t come back. In that sense, protecting forests is an investment in the medical research of your future.

Earth Day 2026 seeks to raise awareness of this and other similarly significant reasons to protect our planet, which – as we’ve seen above – protects us.

If you’d like to know more about Earth Day, there are lots of details on its website, while the specific article on which the above is based can be found here.

Have a great weekend
