Video: 35 Years of World Economic Evolution in 20 Seconds
Watch GDP for the world’s countries change over decades
Today’s video takes a similar approach, but focuses on the evolution of the global GDP breakdown over time. It does not show GDP in absolute terms, but instead illustrates changes to each country’s contribution using annual data from the IMF.
The most obvious observation to note is China’s rise and eventual dominance of the Asian sector of the diagram. The time series starts with Japan as the biggest Asian economy by far, with output greater than all Asian countries combined. At the beginning of the Lost Two Decades (1991-2010), Japan is the 2nd biggest economy in the world, reaching a height of 17.4% of the global economy in 1994. By the end of this challenging period in Japanese history, it gets easily and clearly surpassed by the emerging Chinese giant.
Also noteworthy is that North America has two separate peaks on the recent global economic landscape. First, in 1985 it peaks at 40.1% of global output. It subsequently recedes to a trough of 28.1% a decade later. Then, just after the Dotcom crash in 2001, it re-peaks at 36.6% of worldwide GDP. Today it sits at around 28% again.
Visualizing the World’s Top Plastic Emitting Rivers
Every year, 8 million metric tons of plastic enters the world’s oceans – much of it through our river systems. See which rivers are polluting the most.
Visualizing the World’s Top Plastic Emitting Rivers
Every year, approximately eight million metric tons of plastic enters the world’s oceans – the equivalent of one garbage truck of plastic every single minute.
Every plastic fork and bottle cap bobbing along the surface of the ocean has made its way to the ocean from dry land at some point. As it turns out, the hydrological cycle that keeps water circulating around the planet is also an effective means for trash to hitch a ride from our riverside cities to the open ocean.
As today’s unique, vintage-themed map – via John Nelson at ESRI – visualizes the shocking amount of plastic emitted by major rivers in the world.
It would be hard to overstate plastic’s influence on modern life.
Unfortunately, when plastic is finished doing it’s job, only 10% of it ends up being recycled. Instead, much of the 300 million tonnes of plastic produced each year ends up in the ocean, congregating in places like the Pacific Garbage Patch.
Plastic discharge is especially pronounced in large population centers along large rivers – particularly in rapidly urbanizing regions in China, Indonesia, and Nigeria.
Waste management practices are limited to non-existent in many of Asia’s fast-growing urban areas, so it comes as little surprise that 14 to the top 20 plastic emitting rivers are located on that continent.
The mighty Yangtze – China’s largest river – supports a population of over 400 million people and is the most prolific emitter of plastic waste on the planet. Over 1.5 million metric tons of plastic is unleashed into the Yellow Sea from the river each year.
Stemming the Tide
Plastic emissions data makes one point clear – China is the key to decreasing the volume of trash entering our ocean ecosystems.
The good news is that the Chinese government has recognized the problem, mandating garbage sorting in nearly 50 cities and setting a target for at 35% recycling rate by 2020. A positive first step in the battle to stem the tide of plastic entering ocean systems.
Upward Momentum: Charting a Year of Skyscraper Construction
Nearly 150 skyscrapers were completed around the world last year. Find out which cities and regions are growing skyward the fastest.
Ever since the first towering spires broke through the clouds in New York and Chicago, skyscrapers have remained a potent symbol of economic might.
The tallest buildings require vast amounts of materials, expertise, and capital to make them a reality, but the cities that add these landmarks to their skylines gain prestige and send a powerful message to competing economic centers.
Skyscraper Construction in 2018
Where are the most skyscrapers popping up? Let’s take a look at regional hot-spots around the world.
Note: For the purposes of this article, “skyscraper” will refer to buildings 656 feet (200 meters) or more in height.
China is Flying High
For well over two decades, China has led the world in skyscraper construction, and 2018 was no exception.
The country’s fixation on urban growth and continued economic success is producing tall buildings at a staggering rate. Last year, a mind-boggling 89 skyscrapers were completed in 28 different cities around China.
To put this building boom into perspective, China completed more skyscrapers in one year than New York City’s entire stock of 656ft and taller buildings.
In 2018, no city reached for the stars quite like Shenzhen. The city, which is a hub of China’s high-flying tech sector, now has the second-most skyscrapers in the world, surpassed only by Dubai.
Shenzhen isn’t just building a lot of skyscrapers, it’s building extremely tall ones too.
In 2017, for example, the ribbon was cut on the massive Ping An Finance Center, which is currently the 4th tallest building in the world. Last year alone, four new towers cracked the 1,000ft (300m) barrier.
While China’s scale is hard to beat, other cities in the region are also undergoing dramatic changes, particularly in Southeast Asia. Malaysia and Indonesia completed a combined 13 new skyscrapers, and the Vincom Landmark 81 was added to Ho Chi Minh City’s growing roster of unique skyscrapers.
While there are two skyscrapers under construction in Japan – one in Tokyo and one in Yokohama – none of them were completed last year.
A New Era of American Skyscrapers
After a two-decade lull in skyscraper construction, the United States is embracing taller buildings again. Last year alone, the U.S. added 14 new skyscrapers into the mix, particularly in New York City, where construction cranes dot the horizon. In the past decade, NYC has added 25 new skyscrapers to its iconic skyline.
This trend is showing no signs of slowing down. Between now and 2022, 44 skyscraper projects are expected to be completed in the United States, with the vast majority being built in the Big Apple.
