Over the last 50 years, our use of phosphate based fertilizers has quadrupled. These are essential to modern agriculture, used especially for growing potatoes. A team of journalists, in collaboration with European scientists, set out to search for evidence of the extent of pollution in Morocco. They also want to see if the cadmium in these fertilizers is contaminating potatoes and entering the food chain. Their revelations will make the news and change the law. In this investigation, the Green Warriors team reveal the implications of our addiction to cheap fertilizer.

Every year, 500,000 Europeans are meet a premature fate due to air pollution. One of the main causes of this pollution is coal – a fuel that is still used in many European countries. And this air pollution has no borders – it spreads its contamination throughout the continent, where citizens fight every day for their basic right to breathable air. Many doctors have raised the alarm, but there is a lack of evidence to make real change. Together with scientists and citizens, a team of journalists sets out to search for evidence of air contamination. They will carry out a unique, one-of-a-kind scientific study: comparing the levels of carcinogenic pollutants found in the bodies of European children. Despite the hardships and an arrest by the police, after a year of investigations, their results make the headlines, force a government to act and will draw the attention of the European Parliament. Will the powerful coal lobby resist these revelations?

In this episode, we follow the uranium path from Niger to Europe to reveal the extent of the radioactive pollution created.

From Peru, where the mineral is extracted, all the way to France, where the metal is refined, lead pollutes the earth, the rivers, food supplies, and local people. Despite being banned in numerous products including fuel, paints and the manufacture of pipes, lead is still often used in buildings, weapon development, jewellery and even in batteries. At Évin-Malmaison, France, lead from refineries has contaminated the earth underneath various schools, stadiums, parks and gardens. The farmers of the area can no longer feed their population, because their produce is too contaminated by this lead. It has become the most polluted area in France, and there are thousands of victims. Many children of the area have lead-poisoning and, as a result, serious neurological problems.

Many factories around the world use perfluorinated chemicals to make everyday products. Due to their chemical stability, these compounds are “forever chemicals” They do not break down. Even worse, they can build up inside the human body and cause health problems, including cancer, and compromise the immune system. Companies have routinely dismissed campaigners who insist that cancer cases have risen close tofactories which use perfluorinated chemicals. They claim that only small amounts of chemicals are released into the environment. Our investigation proves that they are wrong.

The investigation begins in Iraq, in the oil fields which extend from Nahr Umar to Halfaya. Black gold is a sensitive subject, a notorious source of conflict throughout Iraq’s recent history. This region is as rich as it is dangerous. We meet local people who are convinced that pollution from flares at the oil refineries is responsible for a rise in illness, including breathing difficulties and childhood cancer. The site is vital for Iraq. It supplies energy to more than half the country.
