English: Well, I would say that it is difficult to define, isn't it? But, in terms of the Welsh language and culture, for example, the point or threshold where damage is caused is when there are more second homes than the current percentage. There are very high percentages in many parts of Wales. When there are more second homes than now, even more damage is done to the Welsh language. There are fewer Welsh-speaking people who can live in their communities. So, how can you define that threshold? That's a very good question, but it's not as simple as setting a percentage for the county as a whole. It is very dependent on individual communities. As I mentioned earlier, you have 1 per cent of homes in Caernarfon being second homes, but if you were to set a threshold of 15 per cent on Caernarfon and the whole county, the danger is then that you have people - . The threshold will have been reached in Dwyfor in terms of second homes and then people will be seeking second homes in Caernarfon and that would then have an impact on the linguistic fabric of that town, which has a very high percentage of Welsh speakers. You have to look at individual communities to decide what the threshold or tipping point is. It's not good enough to see, 'Well, the school's closed; that's a tipping point.' You have to be able to anticipate what the numbers will be. If the numbers aren't going down, then the tipping point has been reached, hasn't it? In terms of prices, that could be a way of measuring a tipping point in terms of who can live in a county, bearing in mind the average wages in that area. That could be a consideration too. It's a very difficult job of work to decide on the threshold, but, in terms of the Welsh language, it's reached when there are more second homes than now. It has already been reached in some parts, in my view. We are in a crisis in some areas, and that's why the demand in Welsh-speaking communities is that no more second homes should be allowed, because it's having an impact now.
Welsh: Mi fuaswn i'n dweud mae'n siŵr ei fod o'n rhywbeth anodd ei ddiffinio. Ond, o safbwynt y Gymraeg a'n diwylliant ni, mae'r pwynt tyngedfennol, lle mae niwed yn cael ei greu, yn digwydd pan fo yna fwy o dai haf na'r ganran bresennol. Mae hynny yn naturiol. Mae yna ganrannau uchel mewn lot o ardaloedd yng Ngwynedd. Y munud mae yna fwy o dai haf na beth sydd yno'n barod, mae'r niwed yn mynd yn fwyfwy i'r Gymraeg. Mae yna lai o Gymry'n gallu byw yn eu cymunedau. Sut ydych chi'n diffinio'r pwynt tyngedfennol? Mae o'n gwestiwn da, ond dydy o ddim mor syml â gosod canran ar gyfer yr holl sir. Mae o'n ddibynnol ar gymunedau'n unigol. Mae gennych chi - dwi'n meddwl mod i wedi'i grybwyll gynt - 1 y cant o dai yng Nghaernarfon yn ail dai, ond petaech chi yn gosod trothwy o 15 y cant ar Gaernarfon a'r sir gyfan, y perygl ydy wedyn mae gennych chi bobl - . Bydd y trothwy wedi'i gyrraedd yn Nwyfor o'r nifer o ail dai, ac mi fydd pobl wedyn yn chwilio am ail dai yng Nghaernarfon, fyddai'n gwneud niwed mawr i wead ieithyddol y dref, sydd â'r ganran uchaf o siaradwyr Cymraeg. Felly, mae'n rhaid sbio ar bob cymuned yn unigol i weld beth ydy'r pwynt tyngedfennol. Dydy o ddim yn ddigon da i weld, 'Wel, os ydy'r ysgol wedi cau, wel, ydy hwnnw'n bwynt tyngedfennol?' Mae eisiau gallu rhagfynegi rhyw fodd beth fydd y niferoedd yn y dyfodol. Os dydy'r niferoedd ddim yn mynd i gwympo, yna mae'r pwynt tyngedfennol yn sicr wedi ei gyrraedd, onid ydy? Mae prisiau hefyd yn fodd o fesur y pwynt tyngedfennol, fuaswn i'n tybio, i weld pwy sy'n gallu byw yn y sir, o ystyried cyflog cyfartalog y fro honno sy'n cael ei ystyried. Mae'n waith anodd ffeindio beth ydy'r pwynt tyngedfennol, ond, o safbwynt y Gymraeg, mae'n cael ei gyrraedd pan fo yno fwy o dai haf na beth sydd yno'n barod. Mae o wedi'i gyrraedd yn barod yn fy marn i, wedi hen fynd heibio. Rydyn ni mewn argyfwng dwys iawn, a dyna pam mae yna alwad mewn broydd Cymraeg i beidio â chael dim mwy o dai haf, a dyna'r sloganau sydd ym mhob man: dim mwy o dai haf. A'r rheswm am hynny ydy bod mwy yn golygu niwed yn syth.
