Hallo Bhavick
Difficult to know what sort of opinions you want, The Environment and Climate Change are pretty big subjects;
Ok, The Environment: too many people have too little time for it, and they don't know what they're missing
Climate Change: yes, it's happening. Yes humans have accelerated it but the world has been through some pretty amazing climate changes in it's time and still life goes on, maybe not as we know it, but then we are just one species. Nature will survive in some way.
Good luck with the publication
