Biennial of Poster Bolivia BICeBé 2023 - Earth Overshoot Day
I designed a series of posters for BICeBé to raise awareness about Earth Overshoot Day. Using humorous illustrations, the posters aimed to show people why it's important to take care of our planet and use its resources carefully.
What is Earth Overshoot Day?
Earth Overshoot Day marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. We maintain this deficit by liquidating stocks of ecological resources and accumulating waste, primarily carbon dioxide in the atmosphere. To determine the date of Earth Overshoot Day for each year, Global Footprint Network calculates the number of days of that year that Earth’s biocapacity suffices to provide for humanity’s Ecological Footprint. The remainder of the year corresponds to global overshoot. Earth Overshoot Day is computed by dividing the planet’s biocapacity (the amount of ecological resources Earth is able to generate that year), by humanity’s Ecological Footprint (humanity’s demand for that year), and multiplying by 365, the number of days in a year:
(Earth’s Biocapacity / Humanity’s Ecological Footprint) x 365 = Earth Overshoot Day
Earth Overshoot Day 2022 was on July 28, one day earlier than 2021, from that day everything is a discount. It reminds us that the persistence of the overdraft, now over half a century, has led to a huge decline in biodiversity, excess greenhouse gases in the atmosphere, and increased competition for food and energy. These symptoms are increasingly manifested through excessive heat waves, wildfires, droughts and floods.
One in ten people in the world suffers from hunger. Despite this, over 1 billion 300 million tons of food are wasted every year.
About 23 trillion kilowatt-hours of electricity are used worldwide each year.
The consumption of wood, paper and agricultural products is one of the biggest reasons for deforestation.
