I always think that it is good to listen to an argument as it develops rather than jump in at the outset. I have tried to explain to you on numerous occasions why it is important to look at different fuels instead of focusing blandly on energy performance certificates when it comes to housing insulation. You did not listen to me then, so I hope that you will listen to me now.

I am delighted to speak in this debate on a motion that I broadly agree with. That does not always happen in a Government debate. Before I talk about it in any great depth, I remind members of my entry in the register of members’ interests, in which I declare that I have a farming interest. I may talk about fertiliser, and I have an interest in a fishery on the River Spey that may be affected by a hydrogen plant. I have made that clear at the outset.

I also agree with the Labour amendment. I have been enthralled in the debate by Daniel Johnson, Brian Whittle and one or two others quoting physics and chemistry. I now remember why I did not do those subjects at school and did others instead.

I support most of the Green amendment, until it gets to the bit about heating, then I lose the thread, so I cannot support it. Frankly, I think that the Greens’ amendment is disappointing and shows a lack of vision.

Let us be clear: I have had to brush up my knowledge of hydrogen, but I know from my experience on the Net Zero, Energy and Transport Committee that about 40 to 45 per cent of electricity is lost when producing hydrogen and that about another 10 per cent of power is lost when hydrogen is turned back into electricity. A huge amount of power is lost in the process, which means that it is quite an expensive way of producing electricity. I have also found out that 9 litres of water are required to produce 1 litre of hydrogen. The process uses quite a lot of that resource, which I will return to in a minute.

Not imminently, then.

In the Highlands, we have a situation in which the health board has a neurodevelopment assessment waiting list of 1,958 young children—four times greater than it was three years ago. NHS Highland says that some children will have to wait in excess of five years even to get an assessment, and that it will take some 15 years to fully clear the existing waiting list. Does the First Minister consider it acceptable that some children will go through their entire school career waiting for an assessment, or that parents will have to fund private care to ensure that their children get the most from their schooling?

I will in a minute, Mr Harvie. I just want to make a point.

The production of hydrogen has costs for the environment as well as for the industry. Therefore, we need to send the industry clear signals about the need for hydrogen, which requires us not to talk down all the things that it could be used for.

Will the member take an intervention?

Will the minister give way?

I thank Marie McNair for bringing this important debate to the chamber. I have spoken about cancer awareness, specifically bowel cancer awareness, in April in previous years, and I have had to mention things that we perhaps do not look at until we see them face to face. I have talked about seeing blood in your poo and the other symptoms, and I think that it is important that we normalise those discussions.

Testicular cancer, which we are talking about tonight, is dangerous. There are 2,500 new cases every year, leading to about 65 deaths each year. Catching it early is the way to deal with it. I am therefore going to try to follow the advice of Kenny Everett, and do this “in the best possible taste”.

On that basis, Deputy Presiding Officer, I will take you on a journey to your local supermarket. If you go to the fruit aisle, specifically the section where you find pears, I ask you to pick up a pear and look at it.

I have to say that, when I was researching this speech, I did not realise that there were quite so many varieties of pears available, from Conference and Concorde pears to Taylor’s Gold and Bartlett pears—in fact, there are some 300 varieties.

When you go to select your pear, you get what you are given on the supermarket shelves. If you pick up a pear and it is misshapen or hard, or if you push it and it causes you pain, you would reject it and do something about it.

That takes me back to the subject that we are talking about tonight, which is testicular cancer. If you find any of those symptoms, you must do something about it. To do nothing is to endanger your life. It might be just those symptoms alone, or there might be other symptoms, such as losing weight, having a cough, having difficulty breathing or a swollen chest, or having a history of testicular cancer in your family, that you are ignoring or do not recognise. However, if you recognise any of them, my strong advice is that you should go straight to the doctor early on and ask to be tested.

My belief is that if we talk normally about testicular cancer—not necessarily by comparing it to a journey to the supermarket, but by talking about the symptoms and raising awareness—we could save lives. It does not matter if only one life is saved—that one life is absolutely vital.

I pay tribute to Cahonas Scotland for its “Check yer bawballs” campaign and to Movember—both charities that are involved in men’s health. I remind everyone that, when it comes to cancer, if you find something at any stage that causes you concern, it will probably cause the doctor concern and it will get checked. If you get it checked, it might be nothing, but if it is something, you could save your life, and that is really important.

One thing is clear: testicular cancer often runs in a family. Is there any way, therefore, that the minister could direct the health service to alert people who have testicular cancer in their family to carry out the checks on a regular basis? That may be one way of reducing the impact quite quickly and simply.

We read that someone with testicular cancer who has surgery to have one testicle removed will not be affected by that. There are also ways of storing semen, should someone have to have both testicles removed. The long-term effect of the surgery is that it keeps the person alive. Does Mr Sweeney agree that we ought to discuss that and make it clear that treatment is better than nothing at all?

In a minute, Mr Hepburn.

I looked at the names that the committee identified as being given to such bills; they include headline bills, shell bills, enabling bills and framework bills. Those are all great names, and they are used by people to promote the bills for what they are: skeletal bills and jellyfish bills.
