Remember when we used just one earth?
In 1970 - the last time humanity consumed the resources of just one earth in a year - many of you probably weren't even born. Since then, we've added almost another earth to our yearly needs. The changes in figures.
Many more of us
In 1970, 3.7 billion people lived on the planet. Our numbers today exceed 7.5 billion. China and India top the global population list, with 1.4 billion and 1.33 billion inhabitants respectively. (Source: Statista, Deutsche Stiftung Weltbevölkerung)
Where do you live?
About 64 percent of the world's population were rural dwellers in 1970. That's changed drastically. In 2016, the proportion had dropped to 45 percent. (Source: WorldBank)
Urbanists
We are becoming city people instead. The number of us living in urban areas rose from 1.34 billion in 1970 to 4 billion in 2016. According to the latest estimates, the majority of us are living in urban areas even in less developed countries. (Source: WorldBank)
What's your ride?
People love cars, right? But do you know how many there are today? The exact figure is hard to come by but estimations draw a relatively a clear picture. In 1970, 250 million cars were on the road worldwide. That number shot up to 1 billion in 2010 and will have skyrocketed to 2 billion by 2020. The figures include cars, all kinds of trucks as well as buses. (Source: Wikipedia)
Like taking a bus
In 1970, the first Boeing 747 began its passenger service, flying 324 passengers from New York to London. Those 324 people were among the 310 million passengers who flew that year. Around 3.7 billion people took to the skies 2016. (Source: Worldbank)
Keep it in the ground?
Do you ever think about oil? Well, there's still plenty in the ground and we should keep it there if we want to avoid catastrophic climate change. But we actually put a lot of effort into getting the black gold out instead. Crude oil production has nearly doubled from 48,000 barrels a day in 1970 to 92,000 barrels in 2016. (Source: Statista)
Up in the air
Whatever we do, we create carbon emissions. And - rather unsurprisingly - we create a lot. Back in 1970, the world's population exhaled about 14.4 billion tons of CO2. In 2015, we breathed out about 35 billion tons. (Source: Statista)
What about the green lung?
The Amazon is one of the most precious and impressive rainforests on Earth. It's described as the world's green lung because it sucks up so much carbon dioxide. But mankind uses lots of wood and the lung is shrinking. Its area fell from 4,100,000 square kilometers in 1970 to 3,300,000 square kilometers in 2016. In other words, 81 percent of 1970's forest cover still remains. (Source: Mongabay)
