What countries are most affected by litter?

Countries most affected by litter typically include those with high population densities, inadequate waste management systems, and significant tourism. Developing nations like Indonesia, the Philippines, and India often face severe litter issues due to rapid urbanization and limited infrastructure. Additionally, coastal countries such as Brazil and Thailand struggle with marine litter, particularly plastic pollution, impacting both wildlife and local economies. The problem is exacerbated in regions where environmental regulations and public awareness are lacking.
