Green Amendments Land Use And Transportation: What Could Go Wrong?, Michael Lewyn

Scholarly Works

Numerous states have amended their constitutions to include a green amendment (that is, an amendment providing that the state's citizens have a right to a healthy environment). Unfortunately, the vagueness of these amendments leaves an enormous amount of interpretative power to courts. This article examines how some courts have interpreted green amendments and how these interpretations risk the misuse of green amendments. Additionally, this article examines how such misuse may be avoided.

Train Travel As An Adventure, Stormy Kara May 2023

Train Travel As An Adventure, Stormy Kara

Honors Capstones

The train is often seen as a slow, old, and antiquated mode of transportation, and the prevalence of train travel in the modern-day United States is nowhere near where it once was. Other methods of transportation, such as the airplane or the automobile, have taken over as primary choices for travelers in the country. The Bureau of Transportation Statistics (2022) reported approximately 80,400,000 trips were taken by airplane in July 2022, compared with just 2,500,000 trips taken via intercity rail in the same time period. However, more than 300 intercity trains operate daily via the quasi-public corporation Amtrak and serve …
