A cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace has found that pollution is the world's biggest cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace . It caused one in six cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace in 2015. This was 16 per cent of all cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace deaths. Most of these deaths were from diseases like cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace disease, lung cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace and stroke. The study is in the medical cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace 'The Lancet'. Researchers said about 92 per cent of pollution-related deaths were in poorer countries, cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace countries with a lot of economic cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace , like India and China. Bangladesh and Somalia were the worst affected countries. Brunei and Sweden had the cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace numbers of pollution-related deaths. A researcher said: "Pollution, poverty, poor cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace , and social cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace are deeply [linked]." He added: "Pollution threatens fundamental human rights, such as the cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace to life." He said air pollution was the biggest killer. It led to 6.5 million cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace deaths. The second biggest killer was cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace pollution. The next cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace killer was pollution in the cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace . A scientist said: "Air pollution is reaching cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace point." She said the people who pollution hit the cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace are those with breathing and lung problems, children and the cancer crisis deaths development elderly especially global hardest health heart injustice journal killer largest lowest premature right study water workplace .
