For some time, we have been aware of the threat that plastic pollution poses to the environment, the ecosystem and human health. The term “single-use plastics”, which is in the title of this debate, might seem like innocuous jargon, but in reality it translates to an estimated 5.5 billion tonnes of discarded plastics, which pollute our lands, seas and oceans. The Ellen MacArthur Foundation predicts that there will be more plastic than fish in the sea by 2050.

This is a global challenge, which will require global solutions. I welcome the European Union’s commitment that all plastic packaging is to be easily recyclable or reusable by 2030. The Scottish Government is to be commended for matching that pledge with a ban on single-use plastics by that same year.

In Scotland we have taken positive steps, with the introduction of carrier bag charges, the announcement of a deposit-return scheme for plastic bottles, and the announced ban on plastic-stemmed cotton buds. Ending the use of disposable plastic straws is the logical next step. In that context, I applaud the work of my colleague Kate Forbes and the work of the fantastic ocean defenders at Sunnyside primary school, whose #NaeStrawAtAw campaign is gathering pace.

Many others have worked hard to raise awareness of plastic pollution. In June 2017, I was pleased to meet members of Greenpeace outside the Parliament, including my constituent, Rachael, who outlined the findings of a recent scientific voyage to research ocean plastics around Scotland’s coastlines. She also gave me a small vial of plastic pollutants that had been recovered on the expedition. The vial now sits in my office and serves as a potent reminder of not only the impact of plastic pollution on our oceans but the collective impact that human society is having on the planet. All the environmental challenges that we face, from global warming and air pollution to the reported commencement of earth’s sixth mass extinction, have been precipitated by human activity. Plastic pollution is only the most recent issue to gain significant public attention.

In debates such as this, in which we consider the impact that we are having on the planet and the species with which we share it, I am sure that all members are, like me, struck with a tremendous sense of guilt at the damage that we have inflicted. However, the debates also provoke a sense of duty and responsibility to repair that damage.

That will not be easy. We must take action where necessary, including legislation where appropriate, but we need to do more. Ultimately, if we are to preserve our environment we will require a fundamental change in culture and a vision of human progress that is not predicated upon never-ending, unsustainable growth, fuelled by hyperconsumerism.

The price of growth cannot be the degrading of the environment that we leave behind. A key pillar of the Scottish Government’s economic strategy is inclusive growth. That concept must include consideration of those who have absolutely no voice—the generations who are yet to come. The issue of plastic pollution speaks to a far bigger debate, which is about not only how we treat our environment but our responsibilities to future generations. We cannot ignore or escape our fundamental duties as temporary custodians of this planet.

Edmund Burke perhaps put that best when, describing society as a partnership, he wrote:

“As the ends of such a partnership cannot be obtained in many generations, it becomes a partnership not only between those who are living, but between those who are living, those who are dead, and those who are to be born. Each contract of each particular state is but a clause in the great primaeval contract of eternal society”.

Our partnership of the living extends to all communities across the globe, and each of us has a duty to bequeath to future generations a planet that is capable of supporting the complex ecosystems of which we ourselves are a part.

The environmental ignorance of past generations who were bound to the earth and parochial in their views might be understood, if not forgiven. However, for the generation that is represented in this Parliament—a generation that has long known of the existence of great floating garbage heaps in the Pacific and Atlantic oceans—there is no excuse.

Kate Forbes pointed out that the number of plastic straws used in EU restaurants would stretch to the moon, but I note that next year marks the 50th anniversary of the moon landings. Of the many enduring images from the Apollo space programme, that of Neil Armstrong setting foot on the lunar surface did not make the biggest impression on me; instead, it was the photo of the earth captured one year earlier by Bill Anders, as the Apollo 8 mission became the first manned spacecraft to complete a lunar orbit. That image, known to us today as “Earthrise”, has been described as

“the most influential environmental photo ever taken”.

In showing the earth as an isolated, fragile and lonely world in the vast and empty expanse of space, it informs a sense of collective global responsibility for our environment more fully than could ever be articulated by words alone.

Let us carry that image with us; let it inform every decision that we take in this place; and in this year of young people, let us recommit ourselves to passing on to the next generation a world where plastics pollution and exploitation of the environment are the issues of a bygone age.
