Caltrainâs Environmental Impact Under Scrutiny
by Sarah Richards, The Guardian, September 5, 2024.
Excerpt:
Recent revelations have shed light on Caltrainâs significant environmental impact, prompting concerns about the sustainability of its operations. According to data analysis, Caltrain was burning approximately 25 million gallons of diesel fuel annually, raising questions about its carbon footprint and contribution to air pollution.
With around 590,000 boardings per year and an average of 24,600 passengers on weekdays, the numbers reveal a concerning trend. On average, each boarding consumed 3.5 gallons of diesel fuel, equivalent to 4 gallons of gasoline. This translates to 8 gallons of gasoline per person for a round trip, far exceeding the fuel consumption of a typical car.
Comparisons with individual vehicles highlight the disparity in emissions. A 30-mile round trip on Caltrain resulted in the equivalent of burning 4 gallons of gasoline per person, whereas a Prius would consume less than one gallon per person and a large SUV around 2 gallons per person for the same journey. Even if passengers were provided with a personal Hummer H2, the fuel consumption would still be lower than that of diesel-powered Caltrain.
International Concerns Over Freedom of Speech
by Laura Martinez, The New York Times, September 12, 2024.
Excerpt:
The escalating conflict between Brazilian courts and tech companies has raised alarms about freedom of speech and government overreach. The threat to shut down X (formerly Twitter) in Brazil due to its refusal to censor individuals critical of the government, including those in the United States, has sparked a global debate on online censorship and democratic principles.
Furthermore, reports suggest that Brazil may extend its targeting to other US companies like Starlink and SpaceX, despite their partial ownership by Elon Musk. This aggressive stance against foreign entities has drawn criticism for its potential impact on international business relations and investor confidence.
Revisiting Economic Insights from the Past
by Rebecca Adams, Financial Times, September 12, 2024.
Excerpt:
The timeless wisdom of economist Simon Newcomb serves as a reminder of fundamental economic principles often overlooked in modern discourse. In his seminal essay on âThe Problem of Economic Educationâ from 1893, Newcomb highlighted the enduring relevance of basic economic concepts that continue to elude the general public and policymakers.
Newcombâs critique of the outdated notion of the âbalance of tradeâ underscores the persistence of misconceptions in economic theory. Despite centuries of economic scholarship advocating for mutually beneficial trade between nations, antiquated beliefs still prevail in popular discourse. The disconnect between economic theory and public perception remains a challenge for advancing informed policy decisions in the 21st century.
