Challenge
Every year, up to 12 million tonnes of plastic end up in the oceans and 80% of this waste found at sea comes from land. As the ocean is the primary climate regulator, preserving marine ecosystems also means fighting global warming.
To take action and implement appropriate and effective public policies, we need to better understand this pollution: data on waste collected during clean-up operations are invaluable and enable us to trace waste back to its origin in order to draw up recommendations. It is also essential to involve the younger generations to raise their awareness of this pollution and prevent the same mistakes from being made again.

It is also essential to involve the younger generations to raise their awareness of this pollution and prevent the same mistakes from being made again.
Solution
To meet this dual challenge, MerTerre has developed the participatory science program Adopt'1 Spot: a central tool of the Zéro Déchet Sauvage collaborative platform. Thanks to regular pick-ups, this program makes it possible toprotect fragile locations subject to chronic pollution and monitor this issue by collecting reliable data on the waste collected.
Through its educational component, Adopt'1 Spot also makes it possible toraise awareness in a fun way among schoolchildren (schools, collèges, lycées, leisure centers, etc.), introducing them to the scientific approach in the field and making them aware of their ability to protect the environment.

Recent result
Adopt'1 Spot is already 150 spots created, half of which are adopted (monitored, cleaned, preserved).
56 structures participating in the program, including 8 schools.
338 collections have been made, freeing nature of 220m3 and more than 25 tons of waste.
More than 8,500 people made aware and already a hundred schoolchildren.
The money will be used for
The sum raised will strengthen the educational aspect of the Adopt'1 Spot program and offer customized support to schools, middle schools and high schools: awareness-raising, on-site waste characterization, coordination of collections, equipment, etc.
Goal
Mi 2023: Accompany a dozen educational structures in classrooms and in the field.
End 2023: A thousand schoolchildren made aware.
End 2023: A thousand schoolchildren made aware.

On the program, awareness-raising and collection to understand the problem of waste abandoned littering the coastline.
Lots of fragments plastics and packaging food plastics picked up including sticks from sucker or cotton tips...

Adopt'1 Spot: 30 children mobilized to preserve nature!
Back to yesterday's (April 25) superb intervention with some thirty children from the centre aéré ACM de la Savine on the plage de la Maronaise!
On the program, raising awareness, collecting then sorting and characterizing waste to understand the problem of abandoned garbage littering the beaches.
All in all, that's around ten kilos and at least 50 L of waste collected thanks to them!
MerTerre thanks you!

Year in review 2022
MerTerre has been keen to introduce students to the scientific approach, so that they have the tools and knowledge to become agents of change. In 2022, we developed a pedagogical kit to offer a playful knowledge path as well as a guide for the proper execution of their waste collection operations. 123 new structures were integrated in 2022, for a total of 449 structures including 15% local authorities and 14% schools.
We have also drawn up a deployment plan for Adopt'1 Spot so that in 2023 schoolchildren will participate in enriching local authority diagnoses via a dashboard developed specifically for this purpose.
Adopt'1 Spot in 2022 means :
- 86 collections with surveys ;
- 20 structures mobilized ;
- 39 spots cleaned ;
- 1,653 participants ;
- 10 surveys using level 1 ;
- 53 surveys using level 2;
- 12 surveys using level 3;
- 11 surveys using level 4;
- at least 3.2 tons of waste collected;
- at least 27 m3 of waste collected, including: 60,921 cigarette butts, 1,722 glass bottles, 1,625 metal cans, 2,051 plastic bottles and 49 tires.

New partner schools for Adopt'1 Spot!
We wanted to raise awareness and support as many schools as possible with the Adopt'1 Spot program to monitor and protect fragile sites. Thanks to part of the donations, we have been able to create an educational kit (awareness-raising documents, collection kit) and are in contact with 4 schools to start our program this autumn.
