Our activities further damage the land surrounding us every year, one of the Earth's most critical natural resources. Land pollution results from human activities, and it has become a severe problem. We do permanent damage and expose the soil to harmful chemicals, which result in the depletion of the soil's quality. The following land pollution facts show how badly our activities affect the environment.
#1 - Over 75% of the land area on Earth is degraded1
According to this evidence-based assessment, land pollution is almost everywhere. This land degradation assessment took more than 100 leading experts on land pollution from 45 countries three years to complete.
Urban planning, green infrastructure development, replanting with native species, and remediation of contaminated and sealed soils are a few proven approaches to reverse this worrying development and help mitigate the impact of waste produced by humans.
#2- If the current land pollution trend persists, the percentage is estimated to rise to 95% by 20502
People and other species we share our planet with will have to migrate as these lands become polluted or deforested. We can expect that more species will go extinct in the coming years as their habitats become uninhabitable for them due to environmental land pollution. We can also expect even more collapse in food production.
#3 - Some 3.2 billion people worldwide are negatively affected by contaminated land2
Land pollution has a direct effect on the well-being of people. These polluted lands may lose their agricultural value, turn to desert, or become uninhabitable wastelands.
#4 - Globally, we’ve lost about 87% of wetlands to land degradation since 19002
The high consumption lifestyle of most developed countries has also contributed to land degradation and soil erosion. This is most common in areas like the Congo region of Africa and South Asia because of their oil palm plant plantations. Learning how to balance our lifestyle will reduce our impacts on nature.
#5 - In 2018, Each person, on average, generated 5.2 tonnes of waste across the EU-273
While we may want to look at big corporations as the enemy of our environment, we all contribute in small ways. Our high-consumption habits lead us to generate lots of waste each day. Many of us can't even go through half of the day without throwing a few items in the trash. This build-up eventually ends up in a landfill somewhere, or worse, the environment.
Romania, Finland, Sweden and Bulgaria, Luxembourg, and Liechtenstein are member states of the EU-27 with a high percentage share in waste production. Researchers claim to see a significant change among the EU-27 Member States that adopted sustainable practices.
#6 - Of the total waste generated in the U.S. in 2018, food waste was the fourth largest category, at about 63.1 million tonnes4
Food made up about 21.6 percent of the total U.S. waste generation in 2018. Food waste continues to be a significant concern for local and state governments. In the U.S., this prompted the creation of the EPA's food measurement methodology that fully accounts for all the ways they manage wasted food.
The food management systems include landfilling practices that meet current standards or newly emerging waste conversion technologies and environmentally sound dirt management through combustion with energy recovery and conversion. Other food management includes donations, animal waste and feed, wastewater treatment, and lots more.
#7- Half of the world's population does not have access to proper waste disposal systems5
Low-income countries often dispose of a large portion of their generated trash improperly in open dumpsites. This often leads to land pollution and also air pollution. Whether these landfills are close to or far away from residential areas, waste materials eventually affect the environment and its people.
#8- 60 million people live less than 10 kilometers away from the world's largest dumping sites5
Land pollution facts like this highlight the risks many people face living close to such areas, resulting in potential illnesses or diseases. Land pollution and air pollution are also common in such places where improper disposal of household and industrial waste can lead to worsening impacts. While there are regulations in place, reducing the amount of waste we put into our lands is the best way to combat land pollution.
#9- Of the 50 largest dumping sites globally, 20 contain both solid municipal waste and hazardous waste products 5
#10- One of the largest dumping sites in the world is called the Estrutural landfill. It is in Brasilia, Brazil, and covers about 136 hectares of land 5
#11 - The Estrutural landfill in Brazil has been active for over 50 years5
#12 - The Estrutural landfill in Brazil alone has collected an estimated 30 million metric tonnes of waste over time, with a daily average estimate of 2 million metric tonnes. Beyond the horrible state of the land, this site has seen many accidents and death reports.
#13 - Results from San Francisco prove we can divert up to 80% of urban waste from landfills[ref]
Much of urban waste ends up in the streets, on the shores, and in landfills worldwide. This is a significant sign of land pollution. Meanwhile, residents can recycle much of this waste. This includes paper waste, plastic waste, aluminum waste, electronic waste, and more. We can always donate the computers or electronics we no longer need or send them off to the proper disposal companies. Sustainable choices and recycling will help solve the problem of plastic and land pollution.
#14 - Researchers found open landfills to be responsible for 91% of all methane emissions, which poses serious health risks for those who live close to them 6
When we burn large, open piles of trash, they emit dangerous carbon dioxide levels. People and waste companies around the world use this method of disposal. Unfortunately, they are ruining the soil quality at their burn sites and producing greenhouse gas, which is heating our planet.
Open landfills and burning sites may seem helpful. But they are also significant contributors to land pollution and air pollution. This poses large-scale risks to both the people living close to the burning sites and our planet at large.
#15 - In China, 20.8% of soil poses a risk of cancer in children7
This study shows the land pollution levels on Chinese farmland soil and how they affect human health risks on a national scale. From the data obtained during the research, we see that the combined pollution ratio of Chinese farmland soil was 22.10%, with 1.23% at severe pollution levels.
The total non-carcinogenic hazard quotients of farmland soil pollution were safe for adults but had a slight non-carcinogenic risk for children. The total farmland area ratio to total carcinogenic for adults was only 1.02%, but the ratio was as high as 20.75% for children.
#16 - About 700,000 deaths yearly are attributable to bacteria from soil pollution [ref]
#17- If not curbed by 2050, researchers estimate that soil pollution would kill more people than cancer[ref]
#18 - In 2017, the U.S. produced 268 million tonnes of waste. By 2018, the number rose to 292.4 million
As the largest consumer market, the US is the end destination of many products from around the world. These items eventually end up in landfills, and they can cause hazardous environmental pollution. Many of these products contain toxic substances. Toxic pollution affects the air, land, and water.
#19 - There are about 1270 landfills in the United States alone8
As the U.S. grapples with growing waste, they must dig up more landfills to manage the problem. This means more land pollution and degradation. Unfortunately, this poses severe health and environmental risks to people living 10 kilometers and more from the dumpsites.
Researchers link an increase in cancer risk, low birth weights, and diarrheal diseases to living near landfills. The Environmental Protection Agency regulates landfills in the U.S. to improve protection from potential contaminants in the waste stream.
#20 - The U.S. landfilled about 50% of the municipal solid waste it generated in 20184
Fast consumption and throw-away habits are significant contributors to the problem of land pollution. As we continue to choose cheap, easy-to-source products with short lifetime value, the land will continue to suffer.
A look at any section of landfill waste globally will show items like paper boxes, bottles, tires, computers, grass clippings, and so on. We can reuse many of these items and materials instead of sending them off to fill the land with more trash.
Adopting personal waste management strategies like reducing purchases, reusing, composting, recovery and treatment, and proper disposal of toxic materials will help reduce landfills.
#21 - Of the 292.4 million tons of waste generated in 2018, the U.S. recycled 69 million tonnes of municipal solid trash 4
#22 - The 69 million tons of recycled municipal solid waste in 2018 was a 2.2% increase from the amount recycled in 20154
These land pollution facts show us that the management of MSW in the U.S. is changing substantially. While the amount of waste the U.S. generates is still on the rise, their waste management system seems to be getting better. Every country must take appropriate steps towards adopting sustainable approaches to reduce land pollution.
#23 - In 2018, the rate of food and other MSW organics composting was 4.1 percent (2.6 million tons)4
Composting doesn't only help to reduce organic waste generation. It's also useful to improve the soil quality of your land or garden area. With your compost, you can enrich your soil and grow native plants. Thereby doing your bit to promote your local biodiversity and land richness.
#24 - The U.S. composted 25 million tons of municipal solid waste in the U.S. in 20184
#25 - The combined rate of recycling and composting of waste in 2018 amounts to 32.1%4
#26 - The total recycling, composting, and energy recovery of waste in 2018 saved over 193 million metric tonnes of carbon dioxide 4
#27 - The combined recycling, composting, and energy recovery of waste in 2018 is equivalent to reducing the cars on roads by 42 million4
#28 - 67% of the materials recycled in 2018 in the U.S. were paper and paperboard4
#29 - 13% of recycled materials in the U.S. in 2018 were metals4
#30 - Glass, wood, and plastic made up only 4-5% of recycled materials in the U.S. in 20184
#31 - Paper and paperboard recycling were responsible for the largest municipal solid waste reduction in 2018. This equates to removing 33 million cars from roads4
