In the last 50 years, human beings have launched thousands of artificial satellites into space. When one of these stops working, it usually falls back toward the Earth and burns up in the atmosphere. Satellites at high altitudes, however, sometimes remain in Earth’s orbit. Later, they may fall apart or explode into thousands of smaller pieces. The higher the satellite, the longer it stays in orbit, and the more likely it is to break apart. The pieces may stay in orbit for years, decades or even centuries.

Student Max Robson, an amateur inventor, built his prototype using rubbish collected from bins including an old bike frame and wheel bearings, the magneto from a Vespa, a battery from a Ford Fiesta and bits of wood to create a wind turbine.

Roadways, beaches, and rivers are some of the areas where trash collects. You can be an environmentally responsible citizen and directly improve your community and city by spending some time cleaning up.
