Environment Bill

Debate between Lord Hodgson of Astley Abbotts and Baroness Bakewell of Hardington Mandeville

Report stage
Monday 6th September 2021 Lords Chamber

[Lord Hodgson of Astley Abbotts (Con)]

My Lords, I have not yet participated in the discussion of light pollution during the stages of this Bill. That is not due to idleness: it is because at the times the Committee or the House were discussing the light pollution issue, I was double-booked on the Charities Bill or the Dormant Assets Bill, in both of which I have a particular interest. That failure means that I should be very brief this afternoon, and indeed I will be. I add my support to the very important point made by my noble friend Lord Randall of Uxbridge and others, and will just make a comment about the all-pervasive nature of light pollution.

I have a house in Shropshire, on the Welsh border, well in the country, 500 feet up. If you go into my garden at night, the whole of the eastern horizon is suffused by the glow of the conurbation from Birmingham. If you swing your eyes round, you hit Kidderminster; south is Hereford; and even when you turn to the West—to Wales—there are frequent patches of light from small towns and villages. I hope, therefore, that the Minister will give due weight to the very important points made by people who are much more expert in this area than I am.

[Baroness Bakewell of Hardington Mandeville (LD)]

My Lords, I support the amendment in the name of the noble Lord, Lord Randall of Uxbridge, to which I have added my name. The noble Lord set out the case for this amendment previously in Committee and has reiterated his arguments this afternoon. I agree with him and the other speakers—the noble Baroness, Lady Jones of Moulsecoomb, the noble Lords, Lord Carrington and Lord Hodgson of Astley Abbotts, and the noble Viscount, Lord Trenchard. I declare my interest as a member of the APPG for Dark Skies and am lucky enough to live in a village with no street lighting. I appreciate, however, that street lighting is an issue that can divide communities. I agree with the noble Earl, Lord Devon, that light pollution is not as important as soil quality, but it nevertheless has a place in this Bill.

Street and security lighting, which are on throughout the night, can have a number of serious side effects. For plants, there is no real darkness in which to rest; nocturnal animals, birds and insects become confused, and this affects their well-being and, subsequently, their numbers. As has already been stated, moths, in particular, being attracted to light, struggle to maintain their normal life patterns. This is particularly damaging, as moths are essential pollinators, which is something we do not always recognise as happening at night. The lack of a plentiful supply of insects and moths has a knock-on effect on bats, for whom they are the main food source. Over recent years we have seen a steady decline in the number of bats. For us humans, exposure to excessive artificial light can lead to sleep deprivation, which affects our overall health and well-being, as was so eloquently demonstrated by the noble Lord, Lord Randall of Uxbridge.

A number of amendments will be debated over the next two weeks that seek to address climate change and redress the loss of biodiversity and species. Light pollution is undoubtedly contributing to this loss, and adding this amendment to the Bill would contribute towards halting and redressing it. The evidence is slim that switching off streetlights late at night causes a spike in crime. Security lights, which cause the greatest distress when excessive, should be focused on the ground, not pointing upwards towards the night sky.

There is also the effect on children’s development. The wonder of the stars at night is lost to millions of children who live in urban areas, where streetlights are never switched off at night. I am lucky enough that I can frequently go out and optimistically think that I can look for a UFO. I never see one, but I nevertheless look up into the dark sky.

The satellite illumination profile of our country shown on TV news programmes clearly demonstrates the level of light pollution over the whole country. There are very few dark sky areas. The exceptions tend to be the national parks, such as Exmoor, which has declared itself a dark sky area.

Light pollution may seem like a very minor issue for some people, but for me, it is absolutely vital that each one of us should be able, if we choose, to go outside at night and enjoy the night sky and the creatures that should, by right, be able to thrive in the darkness. I fully support the noble Lord, Lord Randall, and hope that the Minister will, on this occasion, have some encouraging words for us.
