China has been trying for 13 years to build a railway in the Gobi Desert to reach Mongolia, and there are still 20 kilometers left that no one can finish due to a problem that seems impossible to solve.

At just 14 years old, a boy creates a system without energy, using steel pipes buried in the ground, that irrigates seedlings with moisture from the air, to combat the water scarcity threatening reforestation in northern China.

Where there was only sand and wind at 40 degrees, China built a megacity of 500,000 inhabitants with farms, wineries, and universities in the middle of the desert using melted glacier water from hundreds of kilometers away.

For 45 years, Spain and Morocco have been trying to connect Europe to Africa through a project of just 14 kilometers in the Strait of Gibraltar, and an active tectonic fault on the seabed continues to make the project nearly impossible.

Attracting around 250,000 people a year, a lighthouse 200 meters from the sea, on a 60-meter high cliff, on the North Sea coast in Denmark, becomes one of the most impressive examples of how nature can threaten historical buildings.

Meteorite scares after crossing the sky at over 56,000 km/h, exploding into pieces and leaving a hole in the roof of a house.

The Earth’s climate is experiencing its most unbalanced moment ever recorded, with heat accumulated in the oceans, glaciers at some of the worst recent levels, and global temperatures above pre-industrial levels.
