Curitiba, A Sustainable Urban Oasis

A sustainable city. Curitiba, located in Brazil, stands as a remarkable example of a sustainable urban oasis. Renowned for its innovative urban planning and commitment to environmental preservation, the city has successfully transformed itself into a model of sustainable development.

Curitiba’s integrated and efficient public transportation system is one of its most notable achievements. The city’s Bus Rapid Transit (BRT) system, known as the Rede Integrada de Transporte (RIT), provides affordable and convenient transportation options for residents. With dedicated bus lanes, pre-paid boarding, and strategically designed routes, the RIT has significantly reduced traffic congestion and air pollution, while promoting the use of public transport.

Another key aspect of Curitiba’s sustainability efforts lies in its dedication to preserving green spaces and promoting biodiversity. The city boasts an impressive number of parks, including the expansive Parque Barigui and the beautifully landscaped Jardim Botânico. These green areas not only provide recreational spaces for residents but also serve as natural filters, improving air quality and reducing the urban heat island effect.

Curitiba’s waste management system is also worth highlighting. The city implemented an innovative recycling program in the 1980s, which incentivizes residents to separate and recycle their waste. The program has achieved impressive results, with Curitiba boasting one of the highest recycling rates in Brazil. Additionally, the city promotes composting and operates recycling centers where residents can exchange recyclables for fresh produce or bus tickets, fostering a culture of sustainability and resource conservation.

Furthermore, Curitiba places a strong emphasis on urban planning that prioritizes pedestrians and cyclists. The city’s extensive network of pedestrian-friendly streets, bike lanes, and parks encourages active transportation and reduces reliance on cars. By providing safe and accessible infrastructure for pedestrians and cyclists, Curitiba promotes healthier lifestyles and reduces carbon emissions.

The sustainable achievements of Curitiba are a testament to the city’s visionary leadership and the active participation of its residents. Through innovative transportation systems, green spaces, waste management initiatives, and pedestrian-friendly planning, Curitiba has become an inspiring example of sustainable urban living. As other cities face similar challenges, they can look to Curitiba as a source of inspiration and guidance in their own pursuit of a greener and more livable future.

Decent and intelligent people respect the rights of parents to homeschool their children, but there are two reasons for concern: a) socialization, failure to expose children to their peers, so that they may make friends and come to understand the norms of society, and b) the quality of the education itself.

Almost all homeschooling in the United States is conducted on the basis of a radical rightwing viewpoint, normally a blend of evangelical Christianity and Trumpism.

The Positive Effects We’ve Had on Others Are Profound, Whether We Know It or Not

There’s a theory that most people underestimate the positive effects they’ve had on other people.

Yes, that’s the theme of “It’s a Wonderful Life,” but it’s also the core of the 1995 film “Mr. Holland’s Opus,” in which a music teacher who deemed that his life had been a failure because he never completed writing a great symphony, is gently and beautifully corrected. Please see below.

Renewable Energy Concepts Can’t Violate the Laws of Physics

In the early days of 2GreenEnergy, my people and I were vigorously engaged in finding solid ideas in cleantech that needed funding in order to move forward.

I vividly remember a conversation with a guy in Maryland who was trying to explain the (ostensible) breakthrough that he and his team had made in hydrokinetics. When I was having trouble visualizing what we was talking about, he asked me to “think of it as a river in a box.”

“Oh!” I exclaimed. “You mean you take a box full of standing water, add energy to it get it moving, then extract that energy, leaving you with more energy that you added to it.”

“Exactly.”

I politely explained that the laws of physics, specifically the first and second laws of thermodynamics, make this impossible.

He wasn’t through, however, and insisted that, in his office, his people had constructed a “working model.”

Here’s where my tone descended into something less than 100% polite. I told him that he may think he has a working model, but he’s wrong; if he believes this, he’s ignorant; if he doesn’t, but is conducting this conversation anyway, he’s a fraud.

“But don’t you want to come see it?” he implored.

“No. Not only would not fly across the country to see whatever it is you claim to have built, I wouldn’t walk across the street to a “working model” of something that is theoretically impossible.”

—

I tell this story because the claim made at the upper left is essentially identical. You’re pumping water up out of a stream, and then claiming to extract more energy when the water flows back into the stream.

Of course, social media today is rife with complete crap like this. We’ve devolved to a point where defrauding money out of idiots is rapidly replacing baseball as our national pastime.
