Environment depletion, child labor exploration in Brazil

Worth watching! It is absolutely real.
Iit is happening not only in the Amazon forest but, chiefly in the State where we live, Minas gerais, in the semi-arid region. Nearly 3 million tons of pig iron (raw iron for producing steels) are exported out of Minas Gerais to the United States. Each ton of pig iron consumes abt 3.5 square meter of charcoal.

Wherever we travel, we see hundreds of trucks hauling charcoal to the pig iron industries close to the capital. Massive volumes are illegally produced.

Developing nations, as Brazil, have not learnt how to live in a sustainable way; developed countries, as USA, have not learnt how to live without exploring the unsustained modes of economic growth.

How shall we tackle this severe problem? Not buying unsustainable products or helping the unsustained commnities to live and work sustainably? or both?
