Seed dispersal: Snails help to disperse plant seeds by eating fruits, passing the seeds through their digestive system, and then depositing them in new locations. This process is essential for the reproduction and spread of many plant species. Snails are particularly important for dispersing the seeds of plants that are eaten by birds and other animals, since they are able to pass these seeds through their digestive system without damaging them.
Nutrient cycling: Snails help to decompose plant material and other organic matter, releasing nutrients back into the environment that can then be used by other organisms. This process is vital for the proper functioning of ecosystems, as it helps to maintain soil fertility and other nutrient cycles.
Scavenging: Snails feed on dead animals and other organic matter, which helps to clean up the environment and reduce the spread of disease.
Economic and cultural impacts: Snails are used as food, medicine, and in other commercial products. In addition, they are also important cultural symbols in many societies. If snails were to go extinct, it would have a significant impact on the economies, cultures, and traditions of many people around the world.
Overall, the extinction of snails would have a devastating impact on ecosystems, and it would be a major blow to the quality of life of many people around the world.
