There has been so much publicity recently about plastics and pollution that there has been a massive increase in public awareness of the global environmental impact of the unrestrained use of plastics. In the sea, plastic pollution is mostly invisible until it washes up on the shoreline, yet the ‘invisible’ aspect is more disturbing – microscopic particles of plastic are now found throughout the marine environment and food chain. This card in the Cherish the Earth series shows a crashing wave in Cornwall, with an accompanying quotation by His Holiness the 17th Karmapa, Ogyen Trinley Dorje, head of the Karma Kagyu lineage and one of the most eminent figures in Tibetan Buddhism: “Environmental degradation is far more complex than anything we alone can tackle, but if we can all contribute a single drop of clean water, those drops will accumulate into a clear stream and eventually a vast pure ocean. This is my aspiration.” The Karmapa is well known for his interest and commitment to environmental issues, as well as social justice for all. He frequently highlights the issues in his teachings and life’s work.
