Environmentalism in the Progressive Era & WWI (c. 1890-1920)

Overview

The primary source documents and videos in this section illustrate the growing environmental ethos evident in the early twentieth century, from the Progressive Era through Wold War I.

The Progressive Era, spanning roughly from 1890-1920, can be understood as a period of reform movements formed in response to rapid industrialization, urbanization, and commercialization. Among these reform movements were two early environmental movements known as preservationism and conservationism. Preservationists believed that natural landscapes should be left exactly as they were, and conservationists sought to maintain natural resources in order for them to be best used and enjoyed. John Muir was known as the most prominent preservationist, whereas Gifford Pinchot was known as the most prominent conservationist.

This growing environmental ethos continued into World War I, as Americans conserved and rationed resources in order to support the war effort. Through their participation in garden clubs and local victory gardens, American women and children on the home front used agricultural practices to support soldiers abroad.

The sources in this section exemplify the many perspectives among Americans fostering connections to the environment in the early twentieth century.

1916 Congressional bill to establish the National Park Service & NPS Video

Link: https://dp.la/primary-source-sets/environmental-preservation-in-the-progressive-era/sources/913

Background:

• President Woodrow Wilson established the NPS
  into law through the 1916 “Organic Act.”
• Congress proposed a bill to establish the NPS in response to the growing national ethos toward conservation coming out of the Progressive Era.
• This Congressional report summarizes the bill,
  highlighting the utility behind the creation of the
  NPS under the Secretary of the Interior.

Annotation/Discussion Questions:

• In the first paragraph, the report summarizes the main purposes behind the foundation
  of the National Park Service. What are they?
• Which department will manage the NPS? Why do you think Progressive Era Americans wanted the federal government to oversee parks? How might this fit into broader Progressive Era reforms?
• How does Congress distinguish the difference between the National Parks and the National Forests?

"Everybody Plant a Garden," Richmond Times-Dispatch, April 22, 1917

 

Annotation:

• As a newspaper, this was intended for a wide audience and was published just weeks after the US declared war on Germany during WWI. Victory Gardens were encouraged as a way to help with food shortages and rations during the war. Gardening also gave people something to do and a way to participate that would ease anxieties about the war, food, and the threat of inflation.
• While Garden Clubs were primarily run by women, men and children were also encouraged to join so the whole family could be involved.
• War took millions of men away from their jobs which included agriculture and transportation. Imports of goods from other countries including fertilizer also slowed or stopped. With decreased home grown food and decreased imports of foreign food, shortages occurred  which caused increased prices and hoarding.
• The bank invested in the Garden Club in support of the war effort and the local economy.

Discussion Questions:

• Why might the Bank sponsor a Garden Club? For what reasons might the government have encouraged victory gardens?
• What benefits do you think victory gardens provided?
• What do you need to start a Victory Garden? Can everyone do it? (knowledge, tools)

 

"Yule Exhibits in Portsmouth," Virginian-Pilot, December 11, 1941

Annotation:

• As a newspaper, this was intended for a wide public audience. The date reveals that this Yule Exhibit was held the weekend after the attack on Pearl Harbor.
• A Federation of Garden Clubs through the County indicates that Garden club work was important to the government. Even on the local level, there was institutional support of the war effort.
• This exhibit attempted to make conservation interesting
  to a wide audience by connecting it to Christmas, and
  hoped to encourage families to reduce waste and decorate using recycled materials at home. Reducing
  waste was important during war time when money and
  resources were scarce.
• All of the club’s leaders were women which shows that
  conservation was seen as a “women’s activity.” Garden
  Clubs provided women leadership opportunities. Also note that they were all listed by their husbands’ names.
• Garden Clubs were often made exclusive to only wealthy
  white women. This article shows that in spite of
  segregation, Black women organized their own Garden
  Clubs and advocated for conservation.

Discussion Questions:

• How might Garden Clubs connect to politics?
• Why was gardening an “acceptable” way for women to become activists and professionals?
• What were gender roles of the time? How did this work stay within or reject them?

 

Will you have a part in Victory? 1918

Link: https://www.loc.gov/item/2002712327/

Annotation:

• This was published by the National War Garden Commission, a temporary department created to encourage gardening during WWI.
• Dressed in the American flag, this woman, beautiful and innocent looking, represents the country. She appears delicate and yet powerful, but ultimately worthy of
  protection. She walks with a purpose and sows seeds that presumably will allow the nation to win the war. This imagery is often used for America or American ideals (think Statue of Liberty). The image conjures an emotional attachment to the nation, but also inspires women to join her in the garden or farm fields.
• “Every Garden a Munition Plant” communicates that growing food is just as important as manufacturing guns and ammunition.

Discussion Questions:

• How is this similar to or different
  from other propaganda images?
• Why might America be depicted in
  this way? Where have we seen
  something similar?
• Why do you think the painting/image
  was made to look this way?
• Who is the audience for this image?

 

The Gardens of Victory

Gardens of Victory Video

Link: https://www.youtube.com/watch?v=uBg1ND5X3tA

Annotation:

• This film was made by the United States Office of Civil Defense. It shows the wartime need for vegetable gardens. It advertises that people can get instructions from the government on how to plant a successful garden. The film also says that people benefit from being in the sun and feeling involved in the war effort.
• In both of these sources, every member of the family is shown participating in the garden. The poster is not just focused on a wife or mother, in fact she is in the back. This family also does not appear to be wealthy which suggests Victory Gardening is for everyone.
• “Our food is fighting,” is similar to the WWI Poster that said “Every Garden, a Munitions Plant.” Food is seen as just important as military material and action.

Discussion Questions:

• Do you think this video would have been helpful to people? Why?
• What are some of the benefits victory gardens provided?
• How is this poster similar to or different from other propaganda images?
• Do you see any similarities or differences between these sources and victory garden material from WWI?

 

The Great Depression & The New Deal (c.1929-1945)

Overview

The sources in this section chronicle the environmental aspects of the Great Depression and the New Deal. This period can be studied for both its environmental disaster and federal initiatives toward conservation and reforestation.

In the early 1930s, as the Great Depression wreaked havoc on the economy, the Dust Bowl hit in the Great Plains and the eastern US. The Dust Bowl became known as the largest human caused environmental disaster in US history and is largely attributed to the poor use of agricultural lands as well that were intensified by a long drought in the region. The disaster would lead to mass migration from the Great Plains to Wester states, including California. Primary source photographs, an interview, and a PBS video illustrate the toll the Dust Bowl had on the environment and the people living there.

President Franklin Roosevelt’s New Deal ushered in a series of federally funded programs to alleviate financial burdens of the Great Depression, while also focusing on environmental projects. Notably, the Civilian Conservation Corps (CCC) employed young men to work on conservation initiatives and reforestation projects. Their work would benefit the National Park Service, as well as State Parks around the country.

The Dust Bowl and the Great Depression

Background:

• In the early 1930s, extreme drought hit the Great Plains. For decades, farmers in the region had been over-plowing and depleting the soil through a lack of crop rotation.
• The drought, combined with high winds, caused massive
  dust storms that blew across the plains, further stripping topsoil.
• Along with environmental damage, the Dust Bowl caused
  further economic hardship and health issues.
• The Dust Bowl would also cause a mass migration of
  farmers out of states like Oklahoma, Texas, and Arkansas
  and to California as they searched for better opportunities.

Discussion Questions:

• Describe what you see in the photo.
• Read the caption:
  • Who took this photo and when?
  • Where is this located?
  • Why do you think this photo was taken?
  • Why might this photo have historical significance?

• How does a personal account of the Dust Bowl add to your understanding of what happened?

 

Segregation and Jim Crow in the Environment

Overview

In the early twentieth century, Jim Crow segregation relegated Black Americans to separate and often unequal environmental spaces. In spite of this, Black Americans had robust relationships to the environment through recreation, and commercial or personal ownership.

The sources in this section highlight the specific ways outdoor spaces were segregated through law and social custom. The sources also reveal how Black Americans maintained connection to the outdoors despite the segregation they actively fought, creating spaces of joy and environmental connection for their communities. By exploring these not so distant stories, students will also be able to consider what effects of environmental segregation and racism are still present today.

Ownership and Segregation of Beaches

Annotation:

• Incorporated in 1922, Highland Beach was the first African American municipality in Maryland. It was also the first African American Summer Resort in the Country.
• Many very wealthy African Americans including Mary Church Terrell and Charles Douglass.
• In the late 1800s and early 1900s, most beaches and coastal properties were owned by Black people, particularly formerly enslaved folks and their descendants because the weather and sandy soil made the land less valuable. In the 20th century, predatory white land developers started trying to take these properties and monetize them as segregated beaches and resorts.
• The car and clothing hint at when this was taken, and reveal the presence of Black people in outdoor spaces, specifically beaches, long before desegregation.
• This photo is of a YWCA camp for girls. Recreation, specifically in the outdoors, was not limited to just boys.

Annotation:

• Wade-ins were just like sit-in protests happening at lunch counters during the civil rights movement. Instead of sitting down in restaurants, activists were visiting the beach and swimming in the ocean.
• Many of the beaches where wade-ins occurred, including Rainbow Beach, were not legally segregated, but were “segregated by custom,” meaning that only white people had been welcome there for many years, they were dangerous places for Black people to go.
• Wade-ins advocated for integration. Many communities ended up getting designated Black beaches rather than equal access to all beaches.
• The police are facing the group of protestors. This stance indicates that the protestors were seen as the threat of violence rather than the racist mob.
• Although no violence was reported, ten people were arrested for “unlawful assembly.” This charge is meant for people who enter a space illegally or who threaten public safety. Since there was no legal segregation of Rainbow Beach, neither one of these things was the case.

Discussion Questions:

• What or who do you see in these photos?
• When do you think these photos were taken?
• Why do you think the photos were taken?
• Did anything in the photos surprise you?
• What questions do you have for the photos?

 

The Environmental Movements of the 1960s and 1970s

Overview

By the 1960s, decades of industrialization, resource over-extraction, and use of harmful chemicals had taken a noticeable environmental toll. The sources in this section explore the environmental movements of the 1960s and 1970s and pieces of federal legislation passed in response to the growing popular movement to protect the environment.

By the early 1960s and 1970s, what had been a burgeoning environmental movement grew into the mainstream as activists and scholars alike noticed an intensifying environmental crisis. Some key issues included deforestation, air and water pollution, and species extinction. A few key moments in this growing environmental movement include: the fight against DDT, made popular by Rachel Carson’s Silent Spring; the first Earth Day in 1970; and the American Indian Movement’s March to Wounded Knee in 1973. Important pieces of legislation include the Wilderness Act (1964), Clean Air Act (1970), the Endangered Species Act (1973).

Background

• Created by the Penn Salt Chemicals company
• Published in Time Magazine, June 1947
• Touts the multiple uses and benefits of DDT for different audiences, including commercial farmers and in the home.
• Dichloro-diphenyl-trichloroethane (DDT) was developed in the late nineteenth century, but became commercially available by the 1940s.
• The US military initially used DDT to stop the spread of diseases, like malaria, that spread through insects.
• DDT became commercially available in the 1940s as a pesticide that everyday Americans and famers could use to keep insects off of crops.
• Rachel Carson’s Silent Spring has been credited with exposing the harms of DDT on human, animal, and plant health.
• The movement against DDT can be seen as one of the main signifiers of the modern environmental movement, which had already started to take shape by the early 1960.

Environmental Movement: Legislation 

Background

The growing social and cultural movements throughout the 1960s and 1970s helped push both state and federal legislatures to pass a series of laws to combat air and water pollution, and curb species extinctions. Legislation including the Clean Air Act (1963, 1970), the Wilderness Act (1964), and the Endangered Species Act (1973), provided federal support for the conservation and protection natural environment. These acts, along with the creation of the Environmental Protection Agency (EPA) in 1970, formed the backbone of modern environmental policy, as the federal government began to take a more active role in environmental protection efforts.
