For the majority of human history, litter has not been a big problem. Most of it was organic, food and kitchen waste, which decomposed and went back into the earth.
The problems began as cities grew in size and we gained practical new materials such as plastic. It was handy to be able to store food and other stuff in secure containers. However, this has generated much more waste on the planet that doesn’t break down by itself. Consequently, many countries have built up systems for handling litter. Many poor countries have invested money in other things. In addition, many rich countries, sometimes illegally, send much of their most hazardous waste off to poor countries. This includes car tyres made of toxic rubber and electrical waste made up of mobile phones and computers. But this is no longer an option. The mountains of waste are growing too quickly.
