This is a great idea from the Mexican internet portal company - Terra - to encourage dog owners to pick up after their dog. If the owner scoops the poop then Terra will reward them with some free Wi-Fi time!!
The company is piloting the idea in ten parks in Mexico City and if it catches on it will roll out across the whole of Mexico.
When people throw away their bags of poop in a special box in the park, it calculates the weight and Terra gives everyone free minutes of Wi-Fi in the park. The greater the weight, the more minutes are added - and everyone can enjoy a poo-free park. In an age when people are probably more interested in staring at their smartphone than watching what their dog is doing, it's a smart idea!
