Air and Water Pollution: Impact — House of Lords, 2017-10-26
Topic: Environment
Nigel David Jones (Liberal Democrats, Centre to centre-left): My Lords, I too thank my noble friend Lady Miller for this important debate. We have heard a lot of figures about the number of deaths caused by pollution, but the Lancet Commission on Pollution and Health estimates that 16%—one in six—of all deaths worldwide are caused by pollution. It is a worldwide problem, not just one for this country I will say a few words on a topic about which I have had a bee in my bonnet for many years: clean water supply. Yesterday on TV I saw an advert by the charity WaterAid. It told the story of a little girl aged about six, somewhere in Africa. Every day she gets up and has to walk for hours, carrying a large plastic container to collect water for the family. The water she fills that container with is not clean water like we get out of our taps, but water full of harmful bacteria. Instead of going to school, this little girl spends a large part of her waking hours fetching water that is positively harmful to her and her family. Every time I visit Africa I come back full of anger that we in the developed world allow so many people in poor countries to live like that little girl, with no clean water to drink I once went as an observer to elections in Sierra Leone. The village where I stayed had been in a rebel-held area during the civil war. Most of the buildings were damaged, many with no roof, no water supply and no communications. Every day a rusty United Nations tanker would visit, disgorging into old oil drums what they euphemistically called "water". This "water" was either brown with green bits floating in it or green with brown bits floating in it. I drank bottled water I had brought from the capital Freetown, but the villagers had no choice. They used this substance for washing, drinking and cooking. I have seen similar conditions in other countries—Kenya, Malawi, Uganda, Cameroon and Mozambique Yet, I met a professor of meteorology in Namibia who told me it does not need to be like this. Enough rain falls on the African continent that everyone could have access to clean water. The issue is how to store the rain and then distribute it to the people—water infrastructure. Charities such as WaterAid do what they can and should be supported, but I learned some time ago that WaterAid’s entire worldwide budget is less than what is spent by Thames Water on trying to improve the purity of the water supply in its area from 99 point something per cent to slightly more than 99 point something per cent. We are very good at water in this country and, post Brexit, we are going to need friends all over the world. I can think of no better way to win the hearts and minds of people like the little girl with the plastic container than to help put in the infrastructure so that they can access clean water, so that she can go to school and many fewer people will die from drinking polluted water. So here is a challenge for our Government and for President Trump and our American cousins, too. Instead of threatening to destroy countries such as North Korea, why not use that money instead to help give Africa a decent water supply? Make long-term friends instead of long-term enemies We heard from the noble Earl that pollution is also a huge problem for animals and our wildlife. Animals are exposed to air pollutants through inhalation or ingestion or by absorbing gases through their skin. It is mostly the soft-bodied invertebrates, such as earthworms, or animals with thin, moist skins, such as frogs and toads, which are affected by the absorption of pollutants, while birds are more susceptible to air pollution by inhalation, due to their higher respiratory rates. Plants take up pollutants from the air, which are then deposited on leaves, ready to be ingested by an unsuspecting herbivore Just as long-term exposure to air pollution can lead to chronic respiratory disease, lung cancer and heart disease in humans, the ways in which pollutants affect these animals are diverse and frightening and include respiratory stress, physiological impairment, gross malformations of bones and teeth, birth defects, and, in birds, decreases in egg production and embryo survival. This can lead to changes in birth, growth and death rates and problems in migrating, which can have disastrous consequences for many species of birds. Of course, problems intensify when pollutants enter the food chain Acid rain changes the ecology of our waterways. An acidic stream or river does not make a happy home for our otters, for example, and fish-eating birds such as the osprey will need to find an alternative place to live. Pollution is destroying the environment by impairing its natural beauty, ruining its natural features and depleting natural resources. It is weakening our ecosystem and decimating biodiversity. While humans can, to some degree, protect ourselves from pollution in air and water, our wildlife simply has no defence against it When I discuss these issues with friends they ask, "Well, what can I do?". Here are six things off the top of my head. Next time you change your car, buy an electric or hybrid model. Secondly, stop using insecticides and weed-killers in your garden. Thirdly, investigate using renewable energy in your home. Fourthly, recycle more, particularly plastic, which the noble Lord, Lord Robathan, told us about. Fifthly, contribute to charities such as WaterAid, which are trying, successfully, to supply more people with clean water. Sixthly, encourage your friends, relatives and local representatives—councillors, MPs, even, dare I say, Peers—to take an interest and take action themselves. Air and water: we cannot live without them.
