Biodiversity Loss

Liz Saville Roberts Excerpts

Wednesday 15th May 2024 Westminster Hall

[Caroline Lucas]

I agree wholeheartedly. I will come to that issue in a moment, but joining the Beyond Oil and Gas Alliance does not mean that we will end oil and gas tomorrow. It is a commitment over time, and it sends out a massively important signal to the rest of the world. Frankly, the fact that we have not signed up tells its own story, unfortunately.

The “State of Nature” report, published last year, shone a spotlight once more on the horrifying decline—let us call it what it is: the wanton destruction—of biodiversity across our four nations. It showed that, in that well-worn formulation, the UK is now one of the most nature-depleted countries on Earth. In the course of my lifetime alone, the abundance of species studied across the UK has fallen by almost 20% on average, meaning that just half of the animals, insects and plants with which we are privileged to share our home now remain—from the mosses and the lichens in our woodlands to the internationally important seabird populations that breed on the cliffs and rocky islands of the coastline.

This is a disaster so extreme that, frankly, it is hard to contemplate. Imagine if we lost half our population, or if half the country was swallowed by the sea, or if half the country’s financial wealth was squandered; and yet we have sacrificed, seemingly with few regrets, half our natural inheritance. Scientists are now warning of what they term “acoustic fossils”, as the natural world falls silent and once familiar sounds, such as the dawn chorus, grow quiet or are lost altogether. It could not be clearer that nature is in freefall. Without urgent action to not just halt but reverse its decline, species risk being lost forever from our skies, land and waters. That is a disaster for the individual species concerned, including my favourite bird, the swift, which can fly an extraordinary 1 million miles in the course of its lifetime.

The hon. Lady is absolutely right to raise the situation of migratory birds. There is one tiny glimmer of hope: in Ynys Enlli on Bardsey Island, which is in my constituency, we have had Europe’s first and only dark sky sanctuary since last year. One of the key actions was to replace the bright white light of the lighthouse with a red light, thereby saving thousands of birds’ lives—previously, in one night 2,000 birds had died. We must acknowledge those little glimmers of hope, while also recognising the larger picture and its seriousness.

[Caroline Lucas]

I thank the right hon. Lady for her inspiring intervention, which shows that incredibly simple things can make a world of difference.
