This document summarizes a presentation by Leverage International (Consultants) Inc on maritime threats to the supply chain. It discusses how over 80% of global trade is transported by sea due to the low costs and improving transit times of ocean freight. However, it also outlines threats like piracy, terrorism, theft and natural disasters that can disrupt maritime supply chains. It proposes increased cooperation between governments and the private sector through initiatives like the ISPS Code, C-TPAT, and ISO 28000 to help secure the maritime industry and global trade.
