This is the challenge under Group-B-Environment and Sustainability in which it was assigned to have a discussion on how long the things remain on Earth which we use in our daily basis. So I conducted the webminar and according to challenge I discussed the different types of plastic... conducted a game to explain them how long the plastic,glass and other things remain on Earth....and took a survey of single use plastic. At we all took a pledge that what will be our next step to stop this plastic pollution. In this seminar almost 13 members joined not only from ECoRly BT also one from ECRly and 2 from SWRly.
