  • What was the role of the Department of Agriculture (DOA) in addressing the tumbleweed issue?

    -The DOA was responsible for providing tips on farming and collecting seeds from the continent. When tumbleweed became a problem, they tried to educate people to kill the plants on sight and attempted to contain the situation but ultimately faced challenges due to the vast land and limited resources.

  • How did the Great Plains contribute to the spread of tumbleweed?

    -The Great Plains, with its flat, open, and windy terrain, provided an ideal environment for tumbleweed to spread rapidly, as it allowed them to travel and colonize new areas easily.

  • What was the impact of trains on the spread of tumbleweed?

    -Trains helped spread tumbleweed by carrying them over mountains and to new locations, allowing the plants to establish themselves in previously inaccessible areas.

  • Why was the Department of Agriculture's effort to eradicate tumbleweed unsuccessful?

    -The effort to eradicate tumbleweed was unsuccessful due to the vast land area involved, the limited resources and cooperation available, and the plant's ability to reproduce and spread rapidly.

  • What is the significance of the United States Department of Agriculture's ongoing efforts against tumbleweed?

    -The ongoing efforts by the USDA signify the persistent problem that tumbleweed poses and the department's commitment to finding a solution, despite the challenges faced over the centuries.
