There is also a significant deposit in the sediment of the ocean. Particularly David Attenborough showed much through Blue Planet II. I wouldnt say it is a late realisation. So which is the priority? cosmetic jar manufacturers Of course, the space programme is fashionable and waste management isnt. So I can very much believe that most of the poor waste management in developing countries like India and China and other places is the root cause of the problem. A huge economic opportunity arises from incorporating good waste management. We know in many places in China and India there is no proper waste collection system. Some of us have been talking about plastic in the ocean for many years.It is estimated that there could be more plastic in the oceans than fish by 2050, but there hasnt been an estimate of how much plastic is in the oceans. Almost anywhere on the planet we will find parts of plastic, not big ones but micro plastics. But waste management is causing huge problems. As a result, communities face a situation where there is little option but to put waste into the river and the plastic waste thus gets into the sea. You can say that India is a developing country, but India has a space programme for example and has appalling waste management.  (As told to John Mary). This is a waste management problem, not merely a problem of plastic. There are issues in other countries as well, but the major contributor to plastics in the ocean is always poor waste management
