Wales is playing a key part in a plan to plant a million seeds to help tackle climate change.
Unfortunately the views will be far more impressive for snorkelers than ramblers - because all these plants will be under the sea.
Several sites around Wales will be part of the project to restore large amounts of seagrass to Welsh waters.
Why seagrass?
Though it just looks like, well, grass, it has amazing properties.
Seagrass is a flowering marine plant that captures carbon from the atmosphere up to 35 times faster than tropical rainforests.
Globally, it accounts for 10% of annual ocean carbon storage, despite occupying only 0.2% of the seafloor.
It helps protect our coasts from erosion as it absorbs wave energy, produces oxygen, removes polluting nutirents and also helps protect sea animals.
To put this in context, a 10,000m2 of seagrass can support 80,000 fish and 100 million invertebrate.
Devastatingly, up to 92% UK seagrass has been lost in the last century.
So what are they planning to do and where in Wales will it be?
Sky Ocean Rescue, leading conservation organisation WWF and Swansea University aims to restore 20,000 m2 of the marine plant in west Wales.
This summer, one million seeds were collected from areas like Porthdinllaen in the Llŷn Peninsula by a group of volunteers.
The seagrass, which is found in shallow, sheltered areas along the coast, was reached by snorkelling, diving and wading.
The blades containing the seeds were snapped off, causing no harm to the plant, and then taken to laboratories at Swansea University where they are currently being sorted and prepared, following a method pioneered by the University
The seeds will be put in hessian bags to secure them when they are planted on the seabed, which will take place this winter at a site in Dale Bay, Pembrokeshire.
Historically this area has lost seagrass, but has the right features for it to survive in terms of water depth and sufficient light.
If successful, the pilot scheme could be scaled up around the UK.
Alec Taylor, WWF Head of Marine Policy said: “Seagrass is a wonder-plant that doesn’t get the recognition it deserves, so its steep decline is extremely concerning. Without seagrass the myriad of amazing species that depend on it could disappear, the food we eat will be affected and the amount of carbon in the environment will increase.
“Along with Sky Ocean Rescue and Swansea University we are urgently calling on governments to use the model our project is creating to bring back these lush underwater meadows. Governments also need to work with local communities to ensure that these vital areas are well managed.
"The UK can become a global leader on restoring ocean health and combating climate change, if it uses the solutions that nature provides.”
This is not the only idea for tackling climate change in Wales.
It is not just beneath the waves where the battle against global heating is taking place.
