Half of the inhabitants in the world live in cities. In the following twenty years, the number of urban dwellers will swell to an estimated five billion people. does exness have copy trading transportation systems, many cities particularly in the United States use up enormous amounts of fossil fuels and emit high levels of greenhouse gases. But our planet is quickly running from the carbon-based fuels that have powered urban growth for centuries and we seem to be not able to check our greenhouse gas emissions. Are the world's cities headed for unavoidable failure?
The authors of the energetic book do not consider that oblivion is essentially the destiny of urban areas. Rather, they believe that direction is visionary and sensible planning that can help cities meet with the impending disasters, and look to existing initiatives in cities around the world. Rather than responding with fear (as a legion of doomsaying prognosticators have done), they choose expectation. They confront the issues, describing where we stand now in our usage of oil as well as our contribution to climate change. They then present four potential results for cities: collapse, ruralized, divided, and resilient. In response to their scenarios, they say a new sustainable urbanism could replace today's carbon-consuming urbanism. They address in detail how buildings and new transportation systems can be feasibly developed to replace our low efficiency systems that are present.
That is not a publication filled with blue sky theory (although blue skies are going to be a welcome result of its recommendations). Rather, it's packed with practical ideas, a few of which are working in cities today. It implies these problems are solvable, although it frankly confesses that our cities have issues that may worsen when they are not addressed. And the time to begin solving them is now.
