Snails slow to escape death

Hello world,
The Irish National Biodiversity Centre reports that one third of the snails in Ireland are endangered. Ireland had 150 species of snail, two of which are extinct. Some of these snails live in very small areas of space. Most of the deaths are due to water contamination. This is caused by an increase in good production and harmful farming practices. The Kerry snail is supposed to benefit though, because of its proximity to currents. The only thing to inhibit its spread is the expansion of the territory of the rhododendron. I did not know that there were that many snails in Ireland, but I'm not surprised that they're not doing well. No animal is happy with global warming, but I thought snails were pretty resistant.
