English: I thank the Cabinet Secretary for her consideration. I also met with Roseanna Cunningham when she was visiting Cardiff. I have to say, though, I very much, of course, support our sister party, the Scottish National Party. I don't want them to steal a march on us here in Wales. I want us to be the first to do things like deposit return schemes and alternative ways of tackling plastic pollution. She's right, of course, that we do very well on recycling, but the only countries that do better than us do have a deposit return scheme, I have to say. So, let's examine one other aspect of this, because the UK Government Office for Science published an evidence review, 'Future of the Sea: Plastic Pollution' in July. This found that 70 per cent of all the litter in our oceans is of plastic of different kinds. We also had a report only last week that 83 per cent of tap water surveyed all around the world has been found to contain plastic fibres. So, I do think there are small policy interventions, and small nations can make those policy interventions that really change the way that we view the use of plastic, recycling of plastic and the reuse of plastic. As well as a deposit return scheme, the Welsh Government has discussed the possibility of novel taxes here in Wales, with the new powers, and I certainly got the impression from the Cabinet Secretary before the summer - the Cabinet Secretary for finance, that is - that he was interested in how such small taxes could change behaviour and perhaps be used in an environmental way. Is this something that she is discussing with the Cabinet Secretary for finance, and particularly with a view to taxing or, in some way, levying this wasteful use of plastic?
Welsh: Diolch i Ysgrifennydd y Cabinet am ei hystyriaeth. Cefais innau gyfarfod â Roseanna Cunningham hefyd pan oedd yn ymweld â Chaerdydd. Mae'n rhaid i mi ddweud, serch hynny, fy mod yn cefnogi ein chwaer blaid, Plaid Genedlaethol yr Alban. Nid wyf am iddynt achub y blaen arnom yma yng Nghymru. Rwyf am i ni fod yn gyntaf o ran cyflawni pethau fel cynlluniau dychwelyd blaendal a dulliau eraill o fynd i'r afael â llygredd plastig. Mae'n llygad ei lle, wrth gwrs, i ddweud ein bod yn gwneud yn dda iawn mewn perthynas ag ailgylchu, ond mae gan yr unig wledydd sy'n gwneud yn well na ni gynllun dychwelyd blaendal, mae'n rhaid i mi ddweud. Felly, gadewch i ni archwilio un agwedd arall ar hyn, gan fod Swyddfa Wyddoniaeth Llywodraeth y DU wedi cyhoeddi adolygiad tystiolaeth, 'Future of the Sea: Plastic Pollution', ym mis Gorffennaf. Canfu'r adolygiad fod 70 y cant o'r holl sbwriel yn ein cefnforoedd yn blastig o wahanol fathau. Cawsom adroddiad hefyd yr wythnos diwethaf a ganfu fod 83 y cant o'r dŵr tap a arolygwyd ledled y byd yn cynnwys ffibrau plastig. Felly, credaf fod ymyriadau polisi bach i'w cael, a gall cenhedloedd bychain wneud yr ymyriadau polisi hynny sy'n trawsnewid y modd y meddyliwn am y defnydd o blastig, ailgylchu plastig ac ailddefnyddio plastig. Yn ogystal â chynllun dychwelyd blaendal, mae Llywodraeth Cymru wedi trafod y posibilrwydd o drethi newydd yma yng Nghymru, gyda'r pwerau newydd, ac yn sicr, cefais yr argraff gan Ysgrifennydd y Cabinet cyn yr haf - Ysgrifennydd y Cabinet dros gyllid, hynny yw - fod diddordeb ganddo wybod sut y gallai trethi bach o'r fath newid ymddygiad, a sut y gellid eu defnyddio, efallai, mewn ffordd amgylcheddol. A yw hyn yn rhywbeth y mae'n ei drafod gydag Ysgrifennydd y Cabinet dros gyllid, ac yn arbennig gyda golwg ar drethu neu godi ardoll, mewn rhyw ffordd, ar y defnydd gwastraffus hwn o blastig?
