Lords ChamberMy Lords, I am grateful for the opportunity to speak to Amendment 31 standing in the name of the noble and right reverend Lord, Lord Harries of Pentregarth. In doing so, I also give my support to the lead amendment in this group, Amendment 6, moved by the noble Lord, Lord Teverson. I hope that the Minister can accept Amendment 6 and incorporate it into the Bill. I indeed agree with many of the comments made by the noble Earl, Lord Devon, a moment ago, particularly with regard to trees.
Amendment 31 addresses a tragic contemporary issue: tree disease. I remember, last year hearing the noble and right reverend Lord, Lord Harries, speak extremely movingly about the issue of ash dieback, which has been acutely evident in parts of Wales, particularly in Ceredigion, as he knows better than anyone. I should, perhaps, declare an interest: on our fields we had to fell four ash trees last November, because ash dieback was already devastating them. Our tree feller told me then that I probably face several more trees having to be felled this autumn. It is heart-breaking that, on our roadsides in Wales and along our cycle tracks, we see trees with orange marks designating that they have this awful condition and are doomed to be felled. I support this amendment. We are in the middle of a war against tree disease and, in any such battle, we must be adequately equipped with the facts.
In many ways, it is surprising that the considerations covered by this amendment are not already part of government strategy. If they are, perhaps the Minister could put me right. They certainly should be. I hope that he can provide us with assurances that all these provisions are really covered in legislation or, if they are not, that the Government will seriously consider each of the various proposals included in this amendment. If they cannot accept the wording, perhaps they will bring forward at Report their own amendment that can deal effectively with these issues.
Finally, again, can the Minister give an assurance that there is cross-border co-operation with the Welsh Government on this issue, as tree infections are no respecters of political borders? I urge support therefore for both Amendments 6 and 31.
My Lords, I would like to speak in favour of Amendment 10 in the names of the noble Lords, Lord Randall and Lord Taylor. The effect of light pollution is intrinsically part of the existing four priority areas for which environmental targets will be set, but it is not mentioned in any of the actions identified in the Bill to remedy or mitigate the underlying issues raised by these targets. Hence a separate target to reduce levels of light pollution is necessary and will not be difficult to implement or measure.
I declare my interest, being a vice-chair of the APPG on Dark Skies, like the noble Lord, Lord Taylor of Holbeach, and as the grandson of a knighted astronomer. Light pollution is relevant to human health, nature and wildlife, energy consumption and thereby greenhouse gas emissions. First, on health, epidemiological studies conducted in the United States have identified poorer sleep and anxiety disorders emanating from outdoor illumination, affected physical and mental health and well-being. Constant light is a well-known method of torture. Secondly, there is the effect on nature and wildlife. A review from Nature magazine in 2018 concluded that
“early results suggest that light at night is exerting pervasive, long-term stress on ecosystems, from coasts to farmland”
and
“waterways, many of which are already suffering from other, more well-known forms of pollution.”
The article then mentions a UK study on the timing of bud opening in trees, also raised by the noble Lord, Lord Randall. The study demonstrated a rate of acceleration “similar to that” now “predicted for … global warming”.
A Defra report in 2019 showed a sharp decline in insect numbers, with a 31% drop in insect pollinators between 1980 and 2016, and a 60% decline in the 2,890 priority species from 1970 to 2016. The State of Nature 2019 report by the National Biodiversity Network identified urban areas as particularly affected. In 2017, a paper from Nature highlighted the connection between light pollution and pollinating insect species, suggesting a threat to world food production.
Thirdly, there is the additional and unnecessary fuel consumption associated with aggressive illumination and the extra burden on greenhouse gas emissions. The reason for illumination that is so often given is that of safety. A study by the London School of Hygiene & Tropical Medicine found that crime and road collisions do not increase in dark or dimmed areas.
Measuring light pollution is simple, as mentioned by the noble Lord, Lord Randall, with the use of a system produced by CPRE that can form the basis of monitoring change. Let us use this opportunity to acknowledge and deal with this important area, as encouraged by the Government’s draft environmental principles, encompassing both precaution and prevention. Measures to remedy the problems are not rocket science but clearly achievable through the strengthening of the planning framework, the reform of planning permission processes, the strengthening of statutory nuisance provisions, education, and technological developments. We can also learn from examples of measures taken in countries such as France and Germany.
Surely the amendment has a necessary and worthy place in this important Bill.
My Lords, I shall speak in favour of Amendment 10, to which I have added my name, and I support other amendments in this group. I declare my interest, as others have done, as a member of the APPG for Dark Skies. The noble Lord, Lord Randall, has made the case for his amendment very eloquently, as has the noble Lord, Lord Taylor of Holbeach.
When I was a child—this was a while ago—I was brought up in Bristol. Like all children, I was fascinated by the moon, which shone in the sky. Man had not yet ventured to the moon, which I felt was a distant, magical planet. Although we lived in a city, it was possible to see the night sky. Streetlights were switched off before midnight, probably at about 11 pm. There was much less human activity at night in those days. I was therefore able to concoct wonderful stories in my imagination about the man in the moon and the shadows on the moon’s surface.
Roll forward to today, and the map of the country often shown on news bulletins is of a land illuminated by streetlights that are not turned off. The areas where darkness prevails are few and far between. It is impossible for a child living in an urban area to investigate the sky and see the stars twinkling in the light reflected from the moon.
To move from the emotional view of light pollution to the detail of it, it is impacting our species and ecosystems, and increased artificial light at night is directly linked to negative impacts on energy consumption, human health and wildlife such as bats, insects and plants, as others have referred to. Ten years ago I could walk down the lane at 10 pm and bats would be swooping around overhead, consuming gnats and other flying insects. Today it is very rare to see any bats overhead at night. There is a wealth of information about the effect on birds and insects of artificial light, and others have made powerful speeches about the impact of light pollution on night pollinators and on feeding cycles.
My neighbour has a telescope in their upstairs window to see the stars. How very lucky we are to live in a dark area—the only light pollution that we suffer is from Advent to Epiphany, when the church is illuminated by floodlights—but over 90% of the UK population are estimated to be unable to see the Milky Way from where they live. To my mind, that is a severe limit on their ability to observe and wonder at the world that we live in, as well as having a devastating effect on the ecosystems and biodiversity of the nocturnal environment. The night-time economy is often referred to as a good thing. It is time that the animal, insect and plant nocturnal economy was given protection to ensure its survival. I fully support the amendment from the noble Lord, Lord Randall.
My noble friend Lord Teverson spoke eloquently about the long-term biodiversity target, both onshore and offshore. I share his comments and his concerns about our territorial seas, the marine ecosystems and seagrass.
The noble Baroness, Lady Bennett of Manor Castle, urged us to reduce consumption of resources rather than improve efficiency. To make a difference, both will need to be high on the Minister’s agenda.
Tree planting, which we have debated many times, is essential to carbon sequestration, habitat protection and improving flood alleviation. Protecting our native trees from diseases imported from other countries and those carried on the wind is essential to maintain a steady increase in the number of trees. The noble and right reverend Lord, Lord Harris of Pentregarth, raised tree planting.
The amendment from the noble Baroness, Lady Bennett of Manor Castle, on soil quality is really important; the subject was raised on Second Reading. The noble Earl, Lord Caithness, has also supported this. If we do not get the soil quality right, we will not move forward.
We are all aware of the contribution that cattle make to agricultural emissions—currently accounting for 60%. The Committee on Climate Change recommends that the Government implement a 20% reduction in the consumption of meat and dairy; most speakers referred to that. Can the Minister say whether the Government are preparing a strategy to ensure that this 20% reduction is implemented? Perhaps this will be through raising awareness with the public of the effect on the environment of meat and dairy consumption.
This has been an important and fascinating group of amendments. I look forward to the Minister’s response.
