A0 – The scale of the problem
There is no waste in nature, yet our planet is drowning in humanity’s pollution. Swelling streams of discarded plastics, textiles, electronics and materials from construction, agriculture and industry are overwhelming the systems set up to manage them. Globally, 37% of waste ends up in some form of landfill, the majority of which is dumped in uncontrolled open sites. Other waste is incinerated, buried, composted, or recycled. Since the 1980s, some countries have been exporting toxic or hazardous waste to developing countries, out of sight but still wreaking damage on people and the land. Rising levels of waste are fuelled by our increasing and careless consumption. We have reached peak waste.
Waste contributes to climate change through the production of greenhouse gases. Human activity – including burning oil and gas in factories, heating our homes, emissions from vehicles and planes, and dumping waste in landfill – produces carbon dioxide or methane, gases that are causing the Earth’s temperature to rise. Higher temperatures lead to melting ice caps, which cool the oceans and cause rising sea levels. These, in turn, lead to extreme weather, affecting vulnerable communities and species.
Our toxic levels of waste are damaging the planet. How did we get here?
