According to information from the UNAM, some Mexican coasts lose about 5 meters of beach every year due to sea-level rise. Scientists claim that the biggest problem is that, although we know about this issue, more data is required to find solutions.Curiously, the way to get that data is through photographs of the coastline. And we're not talking about a scientific photograph taken with special cameras; we realized that making a Corona ad could help science. So we invite users around the world to do what they already do: share their moment at the beach by recreating a Corona Ads, and in this way help science collect coastal data from all the beaches in Mexico.
