This underwater sculpture in Lanzarote, Spain is by Jason deCaires Taylor, and titled “Crossing the Rubicon”. It symbolizes a point of no return, a warning to humanity that runaway climate change could leave us with no way back to a stable climate.

This sculpture is part of a larger installation, a collection of sculptures each of which is designed to raise awareness about environmental issues. “Crossing the Rubicon” features 35 figures walking towards a gateway in a 30-metre-long, 100-tonne wall. It is a “line in the sand and reminder that our world’s oceans and climate are changing and we need to take urgent action before its too late,” deCaires Taylor writes.

Walls make sense only to humans, but to wildlife and nature, make no sense and only serve to do harm. The wall we here in the USA hear about so often, between the US and Mexico, has fragmented habitat all along the border, endangering species such as the Mexican gray wolf, jaguars, and bighorn sheep.

The U.S.-Mexico borderlands cover six eco-regions and support abundant wildlife. The border bisects the ranges of some 1,500 native animal and plant species, including 62 listed as critically endangered, endangered, or vulnerable.
