In February of 2018, a dead sperm whale washed up on along the picturesque shoreline of Cabo de Palos in Spain.
Officials noted that the whale was unusually thin, and a necropsy confirmed that the whale died from an acute abdominal infection. Put simply, the whale ingested so much plastic debris – 67 lbs worth – that its digestive system ruptured.
The Plastic Problem, Visualized
Today’s infographic comes to us from Custom Made, and it helps put the growing marine debris problem in perspective.
A Spiraling Problem
The equivalent of one garbage truck full of plastic enters the sea every minute and the volume of ocean plastic is expected to triple within a decade.
Every stray bit of trash that enters the ocean, from a frayed fishing net off the coast of the Philippines to a plastic bottle cap from an Oakland storm drain, all end up circulating in rotating ocean currents called gyres.
For this reason, the Pacific Gyre is now better known by another name: The Great Pacific Garbage Patch.
The Sum of Many Plastic Parts
The Great Pacific Garbage Patch is often misrepresented online as a literal raft of floating trash stretching as far as the eye can see. The real situation is less visually dramatic, but it’s what we can’t see – microplastic – that’s the biggest problem. Tiny fragments of plastic pose the biggest risks to humans because it’s easy for them to enter the food chain after being ingested by marine life.
While derelict fishing gear such as nets and floats are a contributor to the problem, land-based activity accounts for the majority of the garbage circulating in the ocean. Most of the world’s countries have ocean coastlines, and with so many jurisdictions and varying degrees of environmental scrutiny, truly curbing the flow of plastic isn’t realistic in the near term.
No Solution on the Horizon
Garbage patches have formed deep in the middle of international waters, so there is no clear cut way to decide who is responsible for cleaning up the mess. Organizations like The Ocean Cleanup are researching ocean gyres and providing better insight into the extent of the plastic problem. The Ocean Cleanup is best positioned to make a real impact, though executing on their vision will require vast resources and substantial funding.
Nobody likes seeing whales wash up on shore, but for now, a fully-scaled solution may still far out on the horizon.
Understanding How the Air Quality Index Works
This graphic breaks down how the air quality index is measured, and looks at which regions are hardest hit by atmospheric pollution and wildfires.
Understanding How the Air Quality Index Works
Air quality levels have received a lot of attention in recent months.
In the wake of COVID-19 lockdowns, many places reported a marked increase in air quality. Northern India captured the world’s attention when it was reported that the Himalayan mountain range was visible for the first time in decades.
On the flipside, later in the summer, wildfires swept over the Pacific Northwest and California, blanketing entire regions with a thick shroud of smoke that spanned hundreds of miles.
How is air quality measured, and what goes into the health scores we see?
Measuring the Air Quality Index
When we see that air quality is “good” or “unhealthy”, those public health categories are derived from the Air Quality Index (AQI).
In the U.S., the AQI is calculated using four major air pollutants regulated by the Clean Air Act:
- Ground-level ozone
- Carbon monoxide
- Sulfur dioxide
- Particle pollution, also known as particulate matter
Some countries have a slightly different way of calculating their scores. For example, India also measures levels of ammonia and lead in the air.
To make these readings more accessible, the AQI has a scoring system that runs from 0 to 500, using data collected from air monitoring stations in cities around the world. Scores below 50 are considered good, with very little impact to human health. The higher the score gets, the worse the air quality is.
To make communicating potential health risks to the public even easier, ranges of scores have been organized into descriptive categories.
|AQI Score Range||AQI Category||PM2.5 (μg/m³)||Health Risks|
|0-50||Good||0-12.0||Air quality is satisfactory and poses little or no risk.|
|51-100||Moderate||12.1-35.4||Sensitive individuals should avoid outdoor activity.|
|101-150||Unhealthy||35.5-55.4||General public and sensitive individuals in particular are
at risk to experience irritation and respiratory problems.
|151-200||Unhealthy||55.5-150.4||Increased likelihood of adverse effects and aggravation
to the heart and lungs among general public.
|201-300||Very Unhealthy||150.5-250.4||General public will be noticeably affected.
Sensitive groups should restrict outdoor activities.
|301+||Hazardous||250.5+||General public is at high risk to experience strong
irritations and adverse health effects. Everyone
should avoid outdoor activities.
While all the forms of atmospheric pollution are a cause for concern, it’s the smaller 2.5μm particles that get the most attention. For one, we can see visible evidence in the form of haze and smoke when PM2.5 levels increase. As well, these fine particles have a much easier time entering our bodies via breathing.
There are a number of factors that can increase the concentration of a region’s particulate matter. Some common examples include:
- Coal-fired power stations
- Cooking stoves (Many people around the world burn organic material for cooking and heating)
- Smoke from wildfires and slash-and-burn land clearing
Wildfires and Air Quality
Air quality scores can fluctuate a lot from season to season. For example, regions that are reliant on coal for power generation tend to see AQI score spikes during peak periods.
One of the biggest fluctuations occurs during wildfire season, when places that typically have scores in the “good” category can see scores reach unsafe levels. In 2020, Eastern Australia and the West Coast of the U.S. both saw massive drops in air quality during their respective wildfire seasons.
Luckily, while these types of fluctuations are extreme, they are also temporary.
MegaMilk: Charting Consolidation in the U.S. Dairy Industry
This graphic charts the American dairy industry’s shift in milk production from small commercial farms to fewer, larger farms.
MegaMilk: Charting the Consolidation of the Dairy Industry
Today’s dairy industry looks very different to how it did just 30 years ago.
Milk production in the U.S. has increased by a whopping 50% over that time frame—yet, the total number of dairy farms has dropped by three-quarters.
Fewer and larger farms now have the lion’s share of all U.S milk cow inventory. While they have the ability to produce more competitively priced dairy products and provide more value to consumers, it is causing financial devastation for small farmers.
The graphic above uses data from the USDA to chart the rapid consolidation of the American dairy industry between 1992 and 2017.
The End of the Small Dairy Farmer?
In the U.S., the dairy industry is one of the fastest consolidating industries in comparison to almost all other agricultural sectors.
Between 1992 and 2017, small commercial farms with 10-99 cows saw an average decline of 70%. These farms accounted for 48.5% share of all U.S. milk cows in 1992. In 2017, that number stood at just 12.2%.
Over time, small farm production has been replaced by that of bigger and more consolidated “megafarms”—a move that can be attributed to the many benefits that scale brings, such as lower costs of production and the potential to compete in the international market.
|Share of U.S. milk cow inventory (by year)|
|1-9 milk cows||0.9%||0.7%||0.6%||0.4%||0.4%||0.4%|
|10-49 milk cows||19.5%||13.8%||9.2%||6.8%||5.9%||3.6%|
|50-99 milk cows||29%||24.5%||19.1%||13.8%||11.1%||8.6%|
|100-199 milk cows||19%||18%||15.4%||12.8%||10.6%||9.4%|
|200-499 milk cows||13.7%||15.3%||14.7%||13.8%||12%||12%|
|500-999 milk cows||8%||10.2%||12.2%||12.5%||11.3%||10.7%|
|>999 milk cows||9.9%||17.5%||28.8%||39.9%||48.7%||55.2%|
The Need For a Survival Strategy
While small dairy farmers simply cannot keep up with larger farms encroaching on their turf, they also have fluctuations in dairy prices to contend with. Milk prices fell in 2018, narrowing the gap between milk prices and feed costs so much that another wave of farm closures ensued.
To make matters worse, many small dairy farmers are close to retirement age, and according to the USDA, exits are more likely if the farm operator is 60 or older.
Despite the hardship facing small dairy farmers, analysts suggest that consumer backlash against large-scale production could present opportunities for small dairy farmers to create premium artisanal products. However, such initiatives would be entirely dependent on the state of the economy and where consumer’s values lie.
The Wider Implications
With milk production shifting to larger farms, a range of both direct and indirect impacts are being felt across the country.
For example, milk production is now predominantly focused in fewer states such as California and Wisconsin, which together accounted for almost 33% of all U.S. milk production in 2018.
In larger farms, the herds are typically confined to tight spaces— rather than grazing in pastures—making animal welfare an issue for many of these farms. Concern over waste contamination and air pollution also brings the environmental sustainability of larger farms into question as they come under more pressure to reduce their impact on the planet.
Looking beyond the production of milk, changing consumer preferences could result in the most transformative effects on both large and small scale dairy farmers.
While rising populations are increasing the demand for dairy, per capita milk consumption declined by 24% between 2000 and 2017 in the United States. Consequently, the largest dairy producer in the country, Dean Foods, filed for bankruptcy in 2019, followed by another major milk producer, Borden Dairy, just two months later.
Experts claim that changing consumer preferences, along with competition from other beverage categories, are responsible for 90% of the total dairy decline.
No Country for Old Farms
The confluence of changing economics and an aging population of farmers has brought the U.S. dairy farming industry to a tipping point, and the near future is likely to bring a fresh wave of dairy farm closures.
I don’t see anything that would give them hope at this point. The best advice I can give to these folks, dairy farmers, is to sell out as fast as you can.
– Joe Schroeder, Farm Aid
As smaller farms continue to disappear from America’s rural landscape, the impacts of consolidation will not only affect dairy farmers, but entire rural communities too.
