Wow, the magnetic fluid idea is amazing. I wonder if there is any size limitation to the liquid. And, recently, I came across an organization in Germany which uses silica gel to agglomerate microplastics. Thus, they filter and remove plastics.

Sri Nikitha I would also like to see it being applied on a larger scale :)
I checked the link, but they are shy on information. What I managed to learn is that they, among few other techniques, use fluorescent microscopy to detect microplastics. If you could agglomerate microplastics to larger particles, than DIY fluorescent visualization could work.

The will and the way

Yes absolutely! Primarily, the pollution problem should become our own problem rather than a neighborhood issue. People should own it, identify and solve it in different ways. Once people feel and connect to the problem, there is a moment and governments will work on the problem.

For example, in Delhi, the air pollution issue became people's problem with the Air Quality Index and all other measuring systems. People realized and they started dialogues with civil societies, NGOs, and the Government. Within a few years, there were policy interventions and strict laws to restrict air pollution.

So, personalization and localization of the problem are key to bring "the will and the way."
