The Coller FAIRR Protein Producer Index, in its second active year, just released their report analyzing the environmental, social, and governance risks of meat, dairy, and farmed fish producers. One large take away from this year’s study was the lack of attention given to environmental and animal welfare by some of the world’s largest protein producers.

The FAIRR Index looked at 60 different companies and found evidence of lacking sustainability efforts for greenhouse gas emissions, water pollution, food waste, conditions for workers, antibiotic use, and animal welfare. Only 30% of the analyzed companies were able to give the researchers specific environmental strategy plans which focused only on reducing greenhouse gas emissions. One-quarter of the companies refused to even disclose their use of antibiotics on their animals.

As more research regarding climate change emerges, this isn’t just a problem for consumers. The conversation is shifting toward some of the financial consequences of severe weather for these large companies.

“What we’re seeing is that companies in the sector are contributing to many of the risks we discuss in the report, but they’re also deeply vulnerable…to the impacts of climate change,” says FAIRR’s Head of Research, Aarti Ramachandran. In an interview with Forbes, Ramachandran gave an example of an Australian Agricultural Company that lost over $100 million in damages due to extreme flooding.

Ramachandran does leave the report on a positive note acknowledging the increased investments in plant-based proteins by meat and dairy companies. He stated, “we think that, overall, there should be a rebalancing of protein so that animal protein consumption doesn’t continue to grow at the same trajectory, and so that there is a sustainable balance between plant-based and animal-based food.”

Invasive pests contributing to climate change

A study from Purdue University says 15 different kinds of invasive bugs and insects kill so many trees each year, it’s equivalent to 5 million car emissions. 

The report said that while not all dead trees immediately release carbon, part of the dead biomass will eventually make its way into the atmosphere. It says that the large amount of dying trees suppresses the hope of those forests taking enough carbon out of the atmosphere to combat climate change.

Purdue professors and members of the U.S. Forest Service found that of the 15 invasive pests, “nine are pathogens, four are sap-feeders, one is a wood-borer and one is a foliage-feeder.”

The annual loss of biomass from invasive species is 0.04 percent, but the authors of the report warn that number has potential to grow. The report also says that the researchers did not account for losses in urban areas, so the percentage is likely higher.

It said that mitigating future invasions will also affect the changing climate, because currently, the invasive species are significantly contributing to the increase in greenhouse emissions. 

The Amazon is on fire, again

The Amazon rainforest is on fire. There have been over 74,000 fires in the Brazilian Amazon since January, according to a report from the Washington Post, making for an 85 percent increase in fires since last year.

Researchers at Brazil’s space center, INPE, told Reuters that there is nothing abnormal about climate or the amount of rainfall this year in the Amazon. A majority of the fires were started by farmers in the region preparing farmland for planting season, as natural fires in the Amazon are rare. There were hundreds of recorded fires set by farmers on Aug. 10 in an attempt to clear land and further development, much of which is illegal according to the Washington Post. Farmers often use the land for cattle and soybeans.

The Amazon, sometimes referred to as the Earth’s “lungs,” has an extremely role in releasing oxygen and storing carbon dioxide. The Amazon lost 1,330 square miles of forest cover during the first half of 2019, according to The New York Times. The report says that while climate change did not start these fires, a changing climate can make human-caused fires worse. Fires burn more quickly in dry conditions.

According to the European Union’s Copernicus Climate Change Service, the fires have caused a spike in carbon monoxide and carbon dioxide emissions — a serious threat to public health and to global warming.

On The Radio- Drinking water and your health

This weeks segment looks at how nitrate pollution in drinking water can affect pubic health. 

Transcript:

The Environmental Working Group released a study that links nitrate consumption through water to an increased risk for cancer.

This is the Iowa Environmental Focus.

In Iowa, nitrate pollution in drinking water remains an everyday threat. The current federal limit for nitrates in drinking water is 10 milligrams per liter, but according to the study, adverse health risks can be caused by a nitrate amount just one-tenth under that federal limit. The Environmental Working Group recommends a nitrate limit of 0.14 milligrams per liter in order for there to be no health risks.

The risks for bladder and ovarian cancers are increased for postmenopausal women. According to the study, nitrate pollution potentially caused over 12,000 cases of cancer in the U.S. – or 300 cases annually – totaling $1.5 billion a year in medical costs.   

The high volume of nitrates in water can be attributed to Iowa’s farm runoff that contains fertilizer and manure. In 2018, IIHR research engineer Chris Jones released a study that said the Des Moines River, Cedar River, and Iowa River combined produced a nitrate equivalent of 56 million people.   

There are currently no state or federal regulations for farmers in terms of controlling agricultural run off. Some political leaders and farm groups support the voluntary Nutrient Reduction Strategy of 2013, which aims to eliminate 45 percent of the nitrogen and phosphorus that contribute to the dead zone in the Gulf of Mexico.

FDA did not find contamination in Yuma romaine lettuce, PMA calls for investigation into environmental causes

The Food and Drug Administration announced this week that it did not find any contamination in romaine lettuce from the Yuma, Arizona, area. Five sometimes deadly outbreaks have been tied to Yuma since 2012, the FDA said this week.

The FDA tested 118 lettuce samples for shiga toxin-producing E.coli and salmonella. One test came back positive for STEC, but the agency determined it was not pathogenic. According to a report from Politico, the Produce Marketing Association said it’s not taking the results as a sign that everything is fine.

Bob Whitaker, Chief Science and Technology Officer at PMA, said, according to Politico, that due to the limited scope of the sampling, the FDA should not be encouraged to slow down investigations into food-borne pathogenic outbreaks. He added that the industry needs to dig into the role of the changing environment on food and contamination, according to the report.

The World Health Organization reported in 2018 that climate change is likely to have a big impact on food contamination, putting public health at risk. With increasing rainfall, temperatures, and extreme weather, bacteria, parasites, and harmful algae will persist, along with their patterns of corresponding food-borne diseases. Chemical residues of pesticides will be affected by the changes in pest pressure, and the risk of food contamination from organic pollutants and metals in crop soil will be affected as well.

The WHO study also said the risk for food contamination will not be even across the board. While some countries will see an increase in food production, other countries, particularly those that are lesser developed, will see negative impacts from climate change on food security. Climate sensitive illnesses will be one of the largest contributors to global food-related diseases and mortality, WHO reported.

It is currently unknown if climate change had any significant impact on contamination tied to the Yuma region.

Microplastics found in Arctic snow

Pieces of microplastic were found in arctic snow just weeks after World Meteorological Organization and Copernicus Climate Change program announced July 2019 was the hottest month ever recorded, period.

Microplastics are falling from the sky via atmospheric transfer and are landing in remote places in the Arctic in substantial amounts, according to a study from Science Advances published on August 14. Scientists studied ice floes in Fram Strait, an unpopulated expanse of ocean near Greenland, and compared it to populated European sites. The study showed that the populated areas had a higher concentration of microplastics, but that the amount in remote areas was still high.

According to a report from National Geographic, scientists from Germany’s Alfred Wegener Institute for Polar and Marine Research and the Swiss Institute for Snow and Avalanche Research said the amount of microplastics in the atmosphere could potentially pose a risk to public health.  Temperature fluctuation among other things can cause plastics to break down into smaller fragments, which then produces the microplastics.

These institutes have been studying microplastics in the Arctic region since 2002 and have noticed drastic increases over the years. In the Arctic water column they found 6,000 microplastic particles in every 2.2 pounds of mud. In every 34 ounces of melted sea ice, they found 12,000 particles.

The report from Science Advances projects annual waste production to reach 3.4 billion MT in the next 30 years. Additionally, mismanaged plastic waste could reach 265 million MT by 2060. The report also highlights the fact that microplastics are ubiquitous in almost all ecosystems – freshwater, urban areas, terrestrial areas – because plastic is designed to be durable.
