Answer:
Characteristics of a green city are low environmental impact per person, renewable energy generation, a high percentage of people using public transportation, green spaces, recycling programs, etc.
Explanation:
There is an ever-growing interest in making the cities around the world ''green'', mostly because of the growing dangers of climate change and negative environmental impact. This is not an easy thing to do though as it requires big changes in almost every aspect of the cities and their functioning. The basic idea behind these cities is that they are sustainable, ecological, have a high living standard, and protect the environment.
In order for a city of this type to arose it needs to produce most of its energy from renewable sources. The buildings should be ''green'' and there should be a high percentage of green areas. Walking and cycling infrastructure at a high level, and high usage of public transportation. All materials that can be recycled need to be recycled, the poverty rates close to zero, and the population density at a very high level.

With bioengineered foods, you risk ingesting chemicals that are foreign to your body. If you ingest too much of the chemicals, your own body could be changed. For example, you have a natural orange. Scientists want to make your natural oranges bigger and sweeter, so they modify the DNA of the orange. With the modified DNA the new orange changed how it grew, increasing the number of natural chemicals (chemicals created by the orange to grow) it created. These chemicals are ingested by you, the consumer, and after eating your new oranges for a year every day, you notice you may have fertility issues, increased aging, etc. By eating bioengineered foods, you can find changes in your body that wouldn't have occurred if you stuck to that natural orange.
Hope this isn't too long and confusing.
