# To holiday-makers, Mexico’s Caribbean Coast is a tropical paradise of sun, sand and surf. To the locals, it's a money maker. That adds up to a lot of pressure on the coastline’s ecosystems. What takes priority? The final leg of our journey takes us through Mexico City. The megalopolis provides a fertile ground for art and culture. In Tijuana, on Mexico’s border with the United States, it becomes apparent that Latin America does not end here and with each visitor the Latin rhythms resonate through California as well as through the rest of the world.
