What do you understand by the statement "differential sharing of responsibility for environmental well being"?
the qustion is from tenth class NCERT book,chapter2, page number 18, 1st parahgraph, 7th line.
The nature of the question could be better answered with how the text concludes on the statement. I think that the premise of it is that all individuals, nations, and/ or companies possess some level of accountability for the environment's protection. There are individuals who can shoulder more of the burden. This might be where your text could offer more insight. Would this be due to the fact that some nations or companies have had a greater role in creating the conditions of the environment that we now face? Could another reason why there can be a differential sharing be due to a nation's amount of internal wealth and with this, more initiatives in environmental protection can be spearheaded without severe impact on domestic business growth? These are questions that your text and the discussion of it could offer.
Just by looking at the sentence, there seems to be three components that are being highlighted. First, there is the notion of difference. Second, there is the element of sharing. Third there is the idea of environmental well being. So, my interpretation is as follows. All people and groups are responsible for the well being of the environment, but they are responsible in different ways. But because they are doing this together, there is the idea of sharing. This interpretation makes good sense, because each country can help the environment in different ways and we all need to share the task of keeping the environment well.
Not having the book, I can not tell you for sure because I do not have the context. However, here is what this line probably means. Please look in your book to see if it makes sense in context.
My understanding of this is that different people and different countries have different levels of responsibility for maintaining the environment. This idea is often expressed by developing countries when they are discussing climate change. For example, developing countries argue that rich countries like the USA should make more of the sacrifices needed to fight global climate change. They say this because the US can better afford to do this than developing countries can.
Looking at your book, does this make sense?
