World population In demographics, the world population is the total number of humans currently living. The world population was estimated to have reached 7.6 billion as of October 2017 [1]. The United Nations estimates it will further increase to 11.2 billion by the year 2100.[2] The median age of the world's population was estimated to be 30.1 years in 2016, with the male median age estimated to be 29.4 years and female, 30.9 years.[11] Estimates on the total number of humans who have ever lived range in the order of 106 to 108 billion.[21][22][23] Population by region[edit] Meet 'the Tulip,' London's newest skyscraper - CNN Style Written by Jack Guy, CNNLondon First there was the Gherkin, then the Walkie-Talkie and the Cheese Grater.

Solar, wind and nuclear have ‘amazingly low’ carbon footprints, study finds Building solar, wind or nuclear plants creates an insignificant carbon footprint compared with savings from avoiding fossil fuels, a new study suggests. The research, published in Nature Energy, measures the full lifecycle greenhouse gas emissions of a range of sources of electricity out to 2050. It shows that the carbon footprint of solar, wind and nuclear power are many times lower than coal or gas with carbon capture and storage (CCS). This remains true after accounting for emissions during manufacture, construction and fuel supply. “There was a concern that it is a lot harder than suggested by energy scenario models to achieve climate targets, because of the energy required to produce wind turbines and solar panels and associated emissions,” explains project leader Dr Gunnar Luderer, who is an energy system analyst at the Potsdam Institute for Climate Impacts Research (PIK).

How India is building a sustainable city - CNN Style Written by Andrea Lo, CNN In south-east India, 217 square kilometers of farmland along the Krishna River are being transformed into a city billed as an urban utopia. When complete, Amaravati will not only be the new capital of Andhra Pradesh state -- developers hope it will also be one of the most sustainable cities in the world. At its center will be a 5.5-kilometer-long and 1-kilometer-wide Central Park-inspired green spine, according to British architectural firm Foster + Partners, which is leading the project. Solar panels on rooftops will power Amaravati's buildings, while cycling routes, electric vehicles and water taxis will serve the transport network.

Play "Just the Vax" Vaccine Trivia Game “Vaccine Trivia: Just the Vax” is the Vaccine Education Center’s trivia game. As part of the Parents PACK program, the vaccine trivia game offers a fun way to learn about vaccines. It includes four categories of questions about vaccines from which to choose: historical/famous figures, safety, vaccines and vaccine-preventable diseases. Each round presents 10 randomly selected questions in the chosen category and keeps track of your score. At the end, you can compare your score to the average score of other players. Choose other categories or play the same category again to see different questions.

Europe Cities by Population 2019 With a few exceptions, the majority of European cities do not have huge populations. This is partly due to some European countries being relatively small and others having multiple major cities rather than one large capital city. For example, in the United Kingdom, London is the largest city (and the third-largest European city overall), with a population of around 7.5 million, but there are several other important cities, such as Nottingham, Liverpool and Birmingham that each have populations of close to a million. Istanbul in Turkey and Moscow in Russia are by far the largest cities on the European continent (although some may dispute whether they are culturally European, and neither are part of the European Union). Istanbul has a population of almost fifteen million, while 2018 statistics show that Russia's largest city now has more than ten million residents (Saint Petersburg also makes the top five with a population of around five million).
