Bu plant blwyddyn 4 yn plannu coed ym Mhrifysgol Llambed fel rhan o brosiect 'Treeflights' (www. treeflight.com). Roeddent yn plannu'r coed yr un pryd a phlant Kenya er mwyn lleihau ein ol troed carbon. Gwelwyd hyn i gyd dros SKYPE. Mae fideo i'w gweld ar (www.walesonline.co.uk). Year 4 made the contribution to reduce Wales' carbon footprint by planting trees in Lampeter University as part of their Treeflights project. (www. treeflight.com). They planted the trees the same time as the children from Kenya. This was seen live on SKYPE. There is a video on this on (www. walesonline.co.uk).
