On March 15th across the nation, youths gathered to raise awareness for climate change and its effect on our world. In the Ped Mall in Iowa City, over 50 students from Southeast Jr. High gathered to speak to the community about their concerns.

The students came prepared with a bullhorn and took turns sharing their opinions for two hours. They were holding hand made signs and handing out a sheet of climate change facts. While young, the passionate students created quite an audience stating, “the bigger the fuss we make, the more politicians will listen.” Congressman Dave Loesback was present and talked with the students in his office following the event.

From the climate change fact handout:

  • 408 parts per million. The concentration of carbon dioxide (C02) in our atmosphere, as of 2018, is the highest it has been in 3 million years.
  • 800 million people or 11% of the world’s population is currently vulnerable to climate change impacts such as droughts, floods, heat waves, extreme weather events, and sea-level rise.
  • Thermometer records kept over the past century and a half show Earth’s average temperature has risen more than 1 degree Fahrenheit (0.9 degrees Celsius), and about twice that in parts of the Arctic.
  • We have 11 years to reverse the effects of climate change. We must act now.

This weeks segment looks at how deforestation is affecting coffee production. 

Transcript:

Deforestation and climate change may wipe out coffee worldwide. 

This is the Iowa Environmental Focus. 

Aaron Davis, a British botanist, has spent the last 30 years traveling across the world recording the patterns of coffee forests and farms. Sixty percent of coffee species are at risk for extinction due to the effects of climate change and deforestation. Coffee plantations are expected to vanish from the three major coffee producing continents.

Part of Dr. Davis’ research is the development of a barometer to test the biodiversity of forests and risks posed to coffee plants. The most popular coffee bean, arabica, comes from Ethiopia and has been shown to be extremely vulnerable to climate change effects. He reports that the ecosystems are becoming less diverse which mean less food and less shelter for species. 

While there are 124 coffee species, a majority are wild and inaccessible. Dr. Davis and the rest of his team continue their research to find rare coffee plants and new places to farm them. His travels have been directed toward cooler areas. On the teams’ most recent expedition, they found a hillside in Liberia covered in stenophylla, a flowering coffee plant that they are currently testing.

More research will hopefully ensure coffee is available long into the future.

This weeks segment looks at The Green New Deal, a bill for clean transportation.  

Transcript:

The newly proposed Green New Deal gives some framework for a future of clean transportation.

This is the Iowa Environmental Focus.

The Green New Deal, proposed by Representative Alexandria Ocasio-Cortez and Senator Ed Markey, may not end up passing, but the deal serves as a blueprint for potential environmental policies to follow. Some interesting broad goals for the future include high-speed rail and zero-emission public transportation.

The Green New deal also brings up concerns with transportation access. Many low-income communities of color suffer disproportionately from poor transportation infrastructure and vehicle-related pollution.

The deal focuses on public policy, but will likely need private investors backing it to meet its many lofty goals.

Even if the deal does not come to pass, it’s sparked a conversation in Washington and the country about the desperate need for clean, affordable, and accessible transportation.

This weeks segment looks at how GMO crops could help African farmers.

Transcript: 

A new study from Iowa State University says genetically modified crops are far more helpful than harmful

This is the Iowa Environmental Focus. 

GMO crops have been studied extensively. Iowa State agronomy researchers recently examined dozens of previous studies to assess the overall safety of genetic modification in plants. 

They determined that GMO crops are not only safe, but that delaying their adoption poses risks for humans and the environment in the developing world. Insect resistant crops could help African farmers battle an emerging invasive pest, the fall armyworm, which has been devastating corn crops in Africa since 2016. But fear has kept insect resistant corn commercially unavailable in all but one African country. 

Study co-author Walter Suza directs the Plant Breeding E-Learning in Africa Program, which develops digital learning materials for African universities. He hopes the study will help African policymakers embrace GMOs.

This weeks segment looks at new methods of creating dog food with less of an environmental impact. 

Transcript: 

A potential new insect based dog food could help the planet. 

This is the Iowa Environmental Focus. 

Meat production has been linked to increasing emissions of CO2 and methane into the atmosphere. This is the reason many environmental activists choose a vegetarian or vegan diet but humans aren’t the only mammals reliant on meat.

Pets are estimated to eat twenty percent of the meat produced world wide. A pet food manufacturer in the United Kingdom, Yora,  has introduced black solider flies as a protein substitute. Along with less emissions into the atmosphere, the black solider fly based dog food is cheaper to produce and requires less land and water.

At the Royal Veterinary College, pet diet expert Aarti Kathrani confirmed that soldier flies could meet a canine’s nutritional needs. She told the BBC,  “insects can be a very useful source of protein. More studies are needed to show how much of these nutrients can actually be absorbed by a dog’s body- but some studies suggest that insects can provide nutrients for dogs.”

Yora is not the only pet food manufacturer to use flies in their recipe but other manufacturers typically use only a small amount. Yora is currently planning to transition forty percent of their products to majority fly protein.

This weeks segment looks at the negative impact of the Bela Monte Hyrdodam in Brazil. 

Transcript:

Hydropower is one of the world’s leading sources of renewable energy, but in some places it has come at a cost.

This is the Iowa Environmental Focus.

Hydropower accounts for over fourteen percent of all energy globally and about seventy percent of all renewable energy. Although dams help bring power to people, they can also have negative social and environmental consequences.

Researcher Emilio Moran is helping investigate the negative impact of the Bela Monte Hyrdodam in a developing area populated with indigenous communities. The dam is the third-largest in the world, and was built over Brazil’s Xingu (SHIN-GOO) River near the city of Altamira.

The new dams reduced the amount of fish that flow downstream, impacting the fishing yields of villages that rely on the river for their livelihoods. The project took three years to complete, and twenty thousand people were displaced from their homes during that time. Altamira’s population increased by sixty thousand during construction, and the city built hotels and attractions in response. After the dam was completed, however, those sixty thousand workers left, leaving many buildings vacant in their wake.

Hydropower is an important source of power, protecting Brazil from blackouts. It is also much cleaner than coal. But dams are not guaranteed generators of power, and their effectiveness can be altered by rainfall.

Emilio Moran and other researchers are only looking for some accountability, and are pushing for dam developers to mitigate the negative economic and social consequences before building.

This weeks segment looks at developing research on the effects of microplastic pollution.

Transcript:

Scientists are still researching the dangerous effects of microplastic pollution. 

This is the Iowa Environmental Focus. 

A microplastic is defined as any piece of plastic measuring five millimeters in size or smaller. Every year 400 million tons of plastic are produced worldwide. A significant percentage of the plastic becomes litter and can take hundreds of years to decompose. Humans and other species can absorb plastic chemicals and aquatic organisms can absorb these small pieces of plastic into their skin.

Dr. Natalia Ivleva and her team from the Technical University of Munich Institute of Hydochemistry recently wrote a summary report of the technology they are using to test the effects of micro plastic on species. 

When scientists began to notice plastic entering the environment they used optical methods to observe damage. 

More recently scientists began utilizing heat analysis paired with gas chromatography. These methods helps determine the quantity and type of plastic but struggle to determine the size of the particles. 

Using new methods researchers at the Munich Institute were able to confirm plastic in the digestive tracts of water fleas and that mussels digest small particles of plastic under their shells.

Over the next several decades, plastic pollution is predicted to increase. At the end of her report Dr Ivelva emphasized the importance of plastic recycling in the new year.
