Environmental Science...Chapter 6, Section 7.

An ecocity is people oriented because it is designed and built with the well-being and quality of life of its residents in mind. It focuses on creating sustainable and livable environments that prioritize the needs of the people who live there. This includes considerations such as walkability, access to green spaces, public transportation, and community engagement. The goal is to create a harmonious balance between human activities and the natural environment, promoting social equity, health, and overall happiness for the residents.

These three cities, Davis, California; Portland, Oregon; and Chattanooga, Tennessee, are mentioned as examples of cities in the United States that are striving to be more livable and environmentally sustainable. The question asks for the correct answer among the given options, and these three cities are the only ones listed that fit the criteria mentioned in the prompt. Therefore, Davis, California; Portland, Oregon; and Chattanooga, Tennessee are the correct answer.

The statement "all of these answers are correct" means that all of the given statements about Curitiba, Brazil are true. This implies that in Curitiba, day care centers are indeed free for low-income parents, recycled old buses are used as health clinics and soup kitchens, 95 percent of the citizens can read, and 70 percent of the paper used is recycled.

Curitiba, Brazil is known for its sophisticated bus system. The city has implemented a well-designed and efficient public transportation system that includes dedicated bus lanes, express routes, and frequent service. This system has helped to reduce traffic congestion and promote sustainable transportation options. Therefore, if you visit Curitiba, you would expect to find a sophisticated bus system in place.

Plants in an ecocity are adapted to the local climate and soils. This means that they are specifically chosen and cultivated to thrive in the specific environmental conditions of the city. By selecting plants that are well-suited to the local climate and soil, they are more likely to survive and flourish, providing shade and beauty to the city. This also reduces the need for excessive watering and maintenance, making them more sustainable. Additionally, plants that are adapted to the local climate and soils are likely to be more resistant to pests, further enhancing their ability to thrive in the ecocity environment.

The correct answer is taxing land instead of buildings. This refers to a tool used in smart growth or new urbanism strategies where land is taxed at a higher rate compared to buildings. This approach aims to discourage land speculation and promote the efficient use of land. By taxing land instead of buildings, it incentivizes property owners to develop their land and buildings more effectively, discouraging urban sprawl and promoting compact and sustainable development patterns. This approach also helps generate revenue for local governments and can potentially lead to more affordable housing options.
