English: Well, the Member is very keen in wanting a one-example answer, so Pontarddulais is my answer to his second question. I was very pleased to be there at the opening of the Pontarddulais flood defence scheme, a scheme that will indeed do everything that he asked. More generally, look, if we are sensible about these things, then he's right, there's far more that we have to do in order to tackle the climate emergency, and that means that there are some difficult decisions that we will all have to face. Building an M4 relief road, for example, would hardly have contributed to what this country has to do to tackle climate change. Last week, I was being asked by members of that party why we were investigating further actions that were needed to tackle nitrogen oxide concentrations along motorways. These things are all difficult. What you can't do is to say to the Government, 'You must do more of this,' but every time the Government tries to do something about it - nitrate vulnerable zones in the agriculture industry, for example - every time - [ Interruption. ] 'Shameful,' I hear the Member call. I've just been asked a question about climate change and pollution, and yet your party refuses to take action to deal with it. I'm simply making the point to the Member that the points he makes about needing to do more and to do it faster - I agree with him. What that means is there is a responsibility on every member of this Chamber that, when practical actions are taken, you can't try to say, 'Ah, but you can't do that.'
Welsh: Wel, mae'r Aelod yn awyddus iawn i gael ateb un enghraifft, felly Pontarddulais yw fy ateb i'w ail gwestiwn. Roeddwn i'n falch iawn o fod yno yn agoriad cynllun amddiffyn rhag llifogydd Pontarddulais, cynllun a fydd yn wir yn gwneud popeth a ofynnodd. Yn fwy cyffredinol, edrychwch, os ydym ni'n synhwyrol am y pethau hyn, yna mae'n iawn, mae llawer mwy y mae'n rhaid i ni ei wneud er mwyn mynd i'r afael â'r argyfwng hinsawdd, ac mae hynny'n golygu bod rhai penderfyniadau anodd y bydd yn rhaid i bob un ohonom ni eu hwynebu. Go brin y byddai adeiladu ffordd liniaru'r M4, er enghraifft, wedi cyfrannu at yr hyn y mae'n rhaid i'r wlad hon ei wneud i fynd i'r afael â'r newid yn yr hinsawdd. Yr wythnos diwethaf, roedd aelodau o'r blaid honno yn gofyn i mi pam roeddem ni'n ymchwilio i gamau pellach yr oedd eu hangen i fynd i'r afael â chrynodiadau nitrogen ocsid ar hyd traffyrdd. Mae'r pethau hyn i gyd yn anodd. Yr hyn na allwch chi ei wneud yw dweud wrth y Llywodraeth, 'Mae'n rhaid i chi wneud mwy o hyn,' ond bob tro y mae'r Llywodraeth yn ceisio gwneud rhywbeth yn ei gylch - parthau perygl nitradau yn y diwydiant amaeth, er enghraifft - bob tro - [ Torri ar draws. ] 'Cywilyddus,' rwy'n clywed yr Aelod yn galw. Mae cwestiwn newydd gael ei ofyn i mi am y newid yn yr hinsawdd a llygredd, ac eto mae eich plaid chi yn gwrthod cymryd camau i ymdrin â nhw. Rwy'n gwneud y pwynt syml i'r Aelod o ran y pwyntiau y mae'n eu gwneud ynghylch yr angen i wneud mwy a'i wneud yn gyflymach - fy mod i'n cytuno ag ef. Yr hyn y mae hynny yn ei olygu yw bod cyfrifoldeb ar bob aelod o'r Siambr hon, pan fydd camau ymarferol yn cael eu cymryd, ni allwch chi geisio dweud, 'A, ond ni allwch chi wneud hynna.'
