By 2050, about half of the world’s people will live in urban areas.
That means more than 10 percent of the globe’s population lives in cities.
While some urban populations are thriving thanks to economic growth and urbanization, the majority of cities in developed countries are shrinking, even as some rural areas thrive.
Here’s how to find out which areas are thriving, and which ones are going the way of the dodo.
The Global Urban Environment A map shows the global urban environment.

Why do cities matter?
The map shows that the global cities are largely dependent on the global economy, with many areas having very little in the way on the environment or human welfare.
For example, the map shows urban areas in the U.S. as being in dire straits, with one-third of their land area underdeveloped and only a third being fully developed.
The global urban ecology and climate model suggests that these are areas with the highest risks of extreme weather and rising sea levels.
The cities are also highly reliant on fossil fuels, water, and energy, so these are places that could face a massive and rapidly increasing crisis.
The map below shows the top 10 cities with the most water and land use, according to the Global Environment Institute.
This is the water-intensive industrial areas in developed regions, and these cities have a high rate of greenhouse gas emissions.
The bottom 10 cities are mostly agriculture-based areas.
These are areas that depend on agriculture, but also on food imports and the production of products that have to be shipped around the world.
Urbanization and the Urban Environment There are currently 5 billion people in the world, making up nearly half the global population.
Most of them live in cities and towns.
In the U, for example, almost 90 percent of residents live in metropolitan areas.
As a result, cities are becoming more crowded.
According to the World Bank, about 90 percent more people live in small cities than in larger cities, with the rest of the population living in more urban areas and towns, like in Beijing, Singapore, and Mumbai.
The number of people living in a city, and the amount of land that can be used, is also a huge issue.
According the World Resources Institute, the world population is expected to increase by 10 percent by 2050.
That could mean more than a billion more people will need to move to cities, as well as a lot of urban spaces that are not designed for human habitation.
The maps below show the top cities with water and greenhouse gas pollution.
Some of these areas are also very poor, and their people are struggling to feed their families and maintain their basic lives.
The water crisis is also affecting the livelihoods of many rural people.
These people rely on water to drink, to heat their homes, and to heat and cool their gardens.
Urban environments also are a major source of pollution, as more and more people are using water to flush toilets.
Urban ecosystems can also lead to pollution.
According a study by the Center for Science in the Public Interest, one of the biggest polluters of the Earth’s atmosphere is the construction of buildings, such as buildings and cars.
Some studies also have found that pollution in urban environments contributes to global warming.
The climate is changing, and urban environments can’t keep up.
As urban areas become increasingly congested, the air quality in these areas can get worse.
Urban areas have been hit particularly hard by the changing climate, according a 2015 study published in the Proceedings of the National Academy of Sciences.
The study found that while urban areas have experienced a steady rise in CO2, the warming of the atmosphere has actually been greater than what was predicted by the climate models used to predict the global climate.
The paper found that CO2 concentration levels had been rising much faster than predicted, and that this caused urban areas to have more CO2 and more heat waves.
The report noted that in the past 10 years, global temperatures have risen by 0.8 degrees Fahrenheit (0.5 Celsius) in the northern hemisphere, compared to the previous 10 years.
According another study, cities have been getting warmer in many parts of the planet, with areas in India and China having become more acidic, and areas in Mexico and Africa becoming more acidic.
The most acidic areas in Europe and the United States are now considered particularly dangerous, the report said.
