Poisoning the Earth and our health

Lead exposure contributes to about 600,000 new cases of children with intellectual disabilities every year. Aside from the poisoned futures these children suffer, the economic losses are huge: by lowering the IQ of children, lead exposure costs low and middle income countries $977 billion per year.

These shocking facts and tragedies like the mass poisoning in Senegal underscore why it is essential that the world acts immediately to end one of the world's most devastating practices – the unregulated recycling of lead acid batteries.

Every single vehicle in the world uses one of these batteries, which account for more than 80 per cent of the world's lead production. With the rapid rise of vehicle use in developing economies, the amount of lead in the environment will only continue to increase.

While recycling lead from these batteries can generate vital income for families, especially in the developing world, much of the recycling and smelting is done in unhygienic and dangerous conditions – sometimes at home, sometimes with an axe to break open the batteries. These practices allow large quantities of lead to leach into the environment with devastating consequences for ecosystems and human health.

Encouragingly, the world has already proved that it is willing to stop lead from seeping into the environment. These days, only three countries in the world continue to use leaded fuel, which was once one of the main sources of human exposure to the toxic substance.

Similar success has been achieved with lead in paint, which is now regulated in 59 countries thanks to the Global Alliance to Eliminate Lead in Paint, an organisation established by the United Nations Environment Programme (UNEP) and the World Health Organisation.

So we know that, when the world acts together, it can overcome seemingly insurmountable problems. We also know what needs to be done to defeat this insidious menace, which destroys lives, ruins children's future and damages ecosystems.

To begin with, we can improve the quality of lead batteries and so reduce the need for recycling. We can use better technology so that lead doesn't have to be smelted twice before it can be used again. We can insist on better regulation of the lead manufacturing and recycling sector. And we can encourage governments to implement nationwide collection programmes to reduce the amount of lead that is melted down and sold for scrap in the informal sector.

If we can rally the world and implement these cures, then we stand a far greater chance of achieving some of the Sustainable Development Goals set out in the 2030 Agenda – the right to healthy lives, the right to lifelong learning opportunities and the right to live in safe cities while protecting vital ecosystems.

This is why Burkina Faso will table a draft resolution at the upcoming United Nations Environment Assembly (UNEA) that calls on UNEP to work with governments and other stakeholders to help low and middle-income countries modernise the lead battery industry.

It is vital that the world sees UNEA – the world's most powerful decision-making body on the environment – as an opportunity to develop programmes and policies that promote the environmentally-sound recycling of lead batteries.

The stakes are high. If we fail to act now, then we will continue to poison our Earth, the future of our children, the power of our economies and the health of our people. We have the antidote and we simply cannot afford to keep poisoning ourselves.
