How Mexico City engulfed Lake Texcoco, from 16th Century to 2000

For centenaries, the Valley of Mexico was filled with a range of rainwater lakes. The Aztecs built their capital Tenochtitlan on an island in the midst of one of those lakes - Lake Texcoco. They built causeways and channels and floating gardens. The Aztec capital was like the Venice of Mesoamerica.

When Spaniards looted Tenochtitlan, they reconstructed a modern city with a grid. However, this new metropolis would regularly flood, eventually leading to efforts to drain the former lakes of the basin. Little by little, the Tenochtitlan city drained the lakes and extended out over the dry lakebed.

Engulfed Lake Texcoco

Mexico City still has significant flooding problems to this day, but it also faces a seemingly paradoxical situation: it's running out of water. All of the infrastructure proposed at draining the rainwater from the basin serves against attempts to preserve water for human needs. Nowadays, many districts in Mexico City don't have regular running water, and when the rainy period comes, those same districts get far too much water all at once.

To resolve the deficiency problem, the city started piping water in from far away and pumping it up from the aquifer below, creating yet another problem: the city is sinking. 

As the water was sucked up, the ground began to break and crumble like a dried cookie, occurring at various subsidence rates. 

Meantime, rainwater, instead of replenishing the ground, can't infiltrate it thanks to impervious asphalt and concrete surfaces above.

How Long Does Plastic Take to Decompose?

  Plastic: the unwelcome house guest at nearly every corner of our lives — from shopping bags to footwear, coffee cups to car parts. And yet, discarded, plastic doesn't just evaporate into thin air. No, it lingers. For decades. Even centuries. According to statistics presented by Visual Capitalist , plastic daily consumer goods can break down between 20 and 600 years, depending on the composition used, how they were created, and natural elements like water and sunlight they are exposed to. Let's go deeper into why plastic takes so long to break down — and what horrid messes it leaves behind in the process. Why Plastic Isn't "Natural" — and Why That's a Problem Plastic does not naturally exist. It's a product made from petroleum and natural gas. Its long, tough carbon bonds differ from anything naturally found in ecosystems, making it extremely resistant to microbial breakdown. When we toss a plastic bottle or bag away, it's not a matter of if it will s...

Map of Fox Species Distribution

Foxes are small to medium-sized members of the Canidae family, which also includes wolves, dogs, and other related animals. There are about 37 species of foxes distributed around the world, and they inhabit a wide range of environments, from forests and grasslands to deserts and urban areas. Below is the map of fox species distribution  created by Reddit user isaacSW Here are some of the most well-known fox species and their distribution: Red Fox ( Vulpes vulpes ): The red fox is one of the most widely distributed fox species and is found in North America, Europe, Asia, and parts of North Africa. They are adaptable and can live in a variety of habitats, including forests, grasslands, and urban areas. Arctic Fox ( Vulpes lagopus ): The Arctic fox is found in the Arctic regions of North America, Europe, and Asia. They have adaptations that help them survive in cold climates, such as a thick coat that changes color with the seasons. Gray Fox ( Urocyon cinereoargenteus ): The gray ...
