The number of Internet users reaches record highs every year, but did you know that for every tweet, comment, email and google search, a small amount of CO2 is emitted?

The world’s bitcoin network uses enough cooling fans and manufacturing hardware for mining that it’s expected to use as much as 7.67 gigawatts of power by the end of 2018.
That’s about as much power as the entire country of Ireland uses in energy — and it’s expected to reach the same consumption level as Austria.

President Donald Trump’s plan for a southern border wall will cost billions of dollars and has already sparked a diplomatic rift with Mexico. It’s also going to be bad for the planet.
A 1,000-mile (1,600-kilometer) wall would require an estimated 275 million cubic feet of concrete. It would release as much as 1.9 million metric tons of carbon dioxide into the atmosphere, according to Christoph Meinrenken, an associate research scientist at Columbia University’s Earth Institute. That’s more than the annual emissions from every home in Pittsburgh.
What we wear has an embodied footprint from the energy that went into creating its raw materials, assembly, manufacture, final finishing,and transportation. Learn the relative footprint of common fabrics and the relative volume of atmosphere your outfit occupies!
More recent studies show that food system emissions could account for as much as quarter of all human emissions. That is 12% from agricultural production, another 9% from farming induced deforestation, and a further 3% from things like refrigeration and freight.
