How to take photos about low-carbon environmental protection photography?

Personally, it can be divided into two parts:

Warning photos: such as factories and cars with serious sewage discharge, or polluted rivers, pavements, animals and plants, etc.

The second is to take photos of technology recycling: for example, recyclable water treatment plants, recyclable paper mills, machines, etc. It is best to film the recycling process.

Third, photos of low-carbon life: the simplest ones are bicycles, environmental protection bags and so on.

Think of these for the time being
