Africa is a continent of many treasures; it has minerals, diamonds, forests, rich fauna and a lot of people. In the future, consumerism will increase and piles of garbage are going to rise in the same speed as standard of living. The biggest trouble would be plastic garbage, it takes decades before it will disappear from nature. We are now building a hen house from empty mayonnaise, milk and oil bottles. What is the benefit of this? We can use ordinary soil which is free, instead of expensive sand and cement. This is the beginning of the hen house.

If you build a hen house from cement and sand, costs for 35 blocks would be around 18 e.
That is expensive when an average salary is around 37 e / month.
Instead you can fill empty plastic bottles and cans with soil, that has been soaked with water.
Costs: 35 blocks of plastic bottles and cans about 6 e.
A builder saves 12 e which is 1/3 of his monthly incomes and he SAVES NATURE.
