Happy Reverse the Red Day 2025!

Biodiversity is a key pillar in upholding the health of ecosystems around the world, but the decline in global biodiversity is often overlooked as an environmental threat. Reverse the Red is a pioneering global movement that works to reverse biodiversity loss and showcase positive achievements for species on the brink of collapse by celebrating efforts that bring species back from being endangered. Today, 7 February 2025, is the third Reverse the Red Day!

Reverse the Red brings together a collective of like-minded scientists, advocates, and partners to assess, plan, and act for species conservation using science-based approaches. Reverse the Red, as the action hub, provides the tools and expertise to empower government, organisations, and local communities to set and reach conservation targets specific to their areas. The movement makes a point of celebrating and amplifying achievements for species.

What is biodiversity loss?

Reverse the Red is dedicated to reversing biodiversity loss. Biodiversity refers to the variety of life in the world or a particular habitat. This includes plants, animals, bacteria, and fungi – basically, every living thing you can imagine. Every ecosystem in the world hosts a myriad of diverse life forms that play vital roles in maintaining the health of these habitats. In turn, these healthy ecosystems provide humans with the air we breathe and the food we eat. Unfortunately, biodiversity loss is happening at unprecedented rates due to habitat destruction, human consumption, pollution and more. This means that more and more species are becoming extinct, leading to the collapse of valuable ecosystems and the consequent loss of natural resources. For example, cutting down trees for agriculture eliminates shade, temperature and moisture regulation, animal habitats, and nutrient transport services. This is the domino effect that biodiversity loss has on ecosystems.

What is “the Red”?

The International Union for Conservation of Nature (IUCN) established the Red List of Threatened Species in 1964. It has become the world’s most comprehensive information source on the global extinction risk status of animals, fungi, and plants. This list is a critical indicator of the health of the world’s biodiversity and a powerful catalyst for biodiversity conservation and policy change. The Red List provides species-specific information on range, population size, habitat, ecology, use or trade, threats, and conservation actions. This list inspired Reverse the Red. Already, there are more than 46 300 species on it. The organisations and individuals involved in Reverse the Red are working towards the survival of these species and the prevention of more being added to the list.

What is Reverse the Red doing?

How are we boosting biodiversity?

Many of our Aquarium family are familiar with the work of the Two Oceans Aquarium Foundation’s turtle conservation work. The Turtle Conservation Centre works to protect endangered turtles and contribute to the recovery of global turtle numbers.

Turtles are indicator species, meaning their abundance, distribution, and health reflect environmental conditions. Essentially, when there are fewer turtles in the ocean, it is indicative that something is wrong in the marine environment. Not only do turtles’ presence indicate marine health, but they are also keystone species. This means that turtles play a crucial role in the ocean ecosystem – without them, ecosystem health would decline or collapse entirely. Turtles keep beach dunes, seafloor habitats, and coral reefs healthy and jellyfish populations in check.

In the wild, only one or two out of every 1 000 turtle hatchlings survive to adulthood. While this is a natural phenomenon, coupled with increased plastic pollution, climate change, and other human-induced hazards, turtle populations are suffering. Furthermore, all seven species of turtles appear on the Red List.

The Turtle Conservation Centre has treated and rehabilitated five turtle species of varying ages for a range of ailments, from plastic ingestion to severe external injuries. The programme consistently achieves an 85% release rate. This means that the majority of turtles received by our team were successfully treated and rehabilitated, allowing them a chance to reproduce and continue the species.

All the turtles leaving the Turtle Conservation Centre are tagged in some way: larger turtles are satellite-tagged, while hatchlings are microchipped. In October 2024, we satellite-tagged and released our second batch of juvenile loggerhead turtles in a groundbreaking global research project. The tracking information gleaned has been of incredible value to understanding "the lost years", a period in which very little is known about the movements and lifestyles of young turtles. All of the data collected from the Turtle Conservation Centre's work contributes to post-graduate studies and publications, as well as the growing global knowledge base of turtle rehabilitation and treatment plans. Most importantly, by rehabilitating and releasing turtles, the Turtle Conservation Centre is giving turtle species' a greater chance at surviving into the future.

Biodiversity loss is a bigger deal than we realise. While there are myriad issues facing our environment, you can do quite a lot to save it. Start by being smarter about your waste: Think twice about plastic products and try to get into a recycling routine. Most waste products will end up in marine or terrestrial environments, so you can do your bit to break the cycle. Even something as simple as sharing a post about Reverse the Red on your social media will help – the more people are aware of biodiversity loss; the more people can help to reverse it!

You, too, can help to Reverse the Red.
