Mae llygredd plastig a sbwriel yn effeithio ar bob amgylchedd yng Nghymru ac mae plastigion untro yn cyfrif am gyfran sylweddol o’r sbwriel sydd i’w weld ar strydoedd a thraethau ac mewn parciau yng Nghymru. Yn ystod cyfnod cyfyngiadau symud COVID-19, cyfnod gwahanol ac anodd, cafodd llawer o bobl ledled Cymru gyfle prin i ailddarganfod eu hardaloedd lleol a dod i’w gwerthfawrogi’n well. Fodd bynnag, wrth i’r cyfyngiadau gael eu llacio, mae mwy o sbwriel i’w weld.
Plastic pollution and litter affects every environment in Wales, with single use plastics making up a significant proportion of the litter found in Welsh streets, parks  and beaches. During the different and difficult period of the COVID-19 lock-down, many people across Wales had a rare opportunity to rediscover and gain a greater appreciation of their local areas. However, with restrictions easing, littering has become more prominent.
