The Swampbuster Act: Protecting America’s Wetlands & Farming History
21 分钟
||2026年5月7日
Explore the history of the Swampbuster Act and how the 1985 Food Security Act transformed American farming by protecting wetlands from drainage and development.
The Swampbuster Act: Protecting America’s Wetlands & Farming History最佳语录
Swampbuster shifted the relationship between the federal government and the American farmer from one of 'convert at all costs' to 'conserve if you want to participate.' It turned the economics of drainage upside down by making the loss of program benefits a higher risk than the potential profit from converting a wetland.

常见问题
The Swampbuster Act was introduced as part of the Food Security Act of 1985 to address the rapid loss of American wetlands. Before its enactment, approximately 460,000 acres of wetlands—an area half the size of Rhode Island—were being drained or filled annually for agricultural use. This environmental policy marked a major shift in American farming history by discouraging the conversion of wetlands into cropland to preserve these vital ecosystems.
The Food Security Act of 1985 fundamentally changed the relationship between the federal government and farmers by linking agricultural subsidies to environmental conservation. Under the Swampbuster provisions, farmers were informed that if they wanted to continue receiving government assistance and benefits, they had to stop draining swamps and wetlands. This effectively ended a century-long era where government policy actively encouraged the drainage of millions of acres of land.
For over a century, the prevailing mindset in American farming was that swamps were a waste of productive soil. Government policy reflected this view by giving away millions of wet acres to states specifically so they would be drained and farmed. This 'war on mud' viewed drainage as progress until the mid-1980s, when the ecological value of these areas was finally recognized through new conservation laws and shifting federal priorities.

我买 BeFreed 正好 23 天，从那以后每天都在用。它已经完全融入了我的日常工作流和学习习惯。
@jayallen
说实话，这个 app 超出了我所有的预期。我可以让它就任何主题生成音频，无论是什么，效果都很惊艳。我的专业领域是心理治疗方向，而且是多学科交叉的，但它给出的内容非常准确。
@Raguipa
我最感激的是它大大减少了我刷手机的时间——花在搜索上的时间少了，吸收信息的时间多了。完整有声书、播客加上学习计划的组合，真的很出色。
@colonyofcreatorsNGO
我做 PhotoReading 快速学习讲师已经 24 年了… 书籍、阅读和学习就是我的本行，而 BeFreed 用一种创新的方式，把知识变得特别容易吸收，做得非常出色。
@BeFreed user
它不只是一个书籍摘要 app。我用过「有趣」这个阅读模式，比传统方式的摘要好得多，理解观点也更容易，光这一点就值回票价。
@austinakon
我爱这个 app。用了几天，完全停不下来。作为开始，再好不过了。
@jcrules328
我真的很喜欢这个产品；已经试用了大概一个月，感觉挖到宝了。它特别好用，因为我可以用 BeFreed 创建自己想学的主题，声音也很棒，旁白选择多到用不完。
@DanielCZ
我特别喜欢它能把有用的信息和想法浓缩成 8-15 分钟的播客式音频。我本来不太爱听播客，因为废话太多，但它把这些全都去掉了。
@BeFreed user
我正在读博士的最后阶段，需要读大量不熟悉的材料… 用 BeFreed，只要输入一个提示，app 就会帮你找到源材料并生成一期音频播客。我觉得 BeFreed 的流程比 NotebookLM 更顺畅。
@Brad
我经常在做早餐、散步、通勤的时候上 YouTube 找点东西听，而 BeFreed 提供了更有针对性的选择，没有广告，也没有废话！
@BeFreed user
这个平台最棒的地方是它的多面性。真的没有任何主题是它讲不了的，你丢给它什么它都能处理… 很少能找到一个毫无限制、又真正兑现承诺的学习工具。
@jayallen
BeFreed 太棒了。界面好用，让我花在找功能上的时间更少，花在学习上的时间更多。有声书、播客和学习计划的组合是天才设计，彻底改变了我的日常。
@BeFreed user
一开始我花了点时间才弄明白怎么生成意大利语的播客，然后就——哇！太棒了！我可以让它讲解任何一个话题，它讲得又好又聪明！
@matteo77
BeFreed 已经成了我每天都用的有声书 app… 我最喜欢的是，把自己的文字放进去，它就能生成随时随地都能听的音频。
