You are partially correct there but it is nuanced.
"Industry" has various forms. Firstly we will dispense with fireworks which don't just cause immediate pollution and other hazards ( you can read
this recent article about the harm of your mentioned "green crackers" ) but also cause secondary harm through the factories they are produced in.
Now, about "Industry".
Vehicular pollution : I am sure India and China are the most polluting countries in vehicular pollution through their population buying two wheelers ( especially in India ) and the neo-rich middle class buying four wheelers. The vehicles not only directly create pollution ( all year round ) through petroleum fuel emissions but also secondary pollution through the factories they are produced in. Think about the pollution in the immediate factory and then through the raw materials needed and where they are obtained from. Double this through the many models of vehicles brought out by so many companies a few times every year. The solution is multi-level. First, abolish the system of personally-owned private transport. Make transport through efficient public transport ( ideally buses ) and through the occasionally called four-wheeler taxis that can be driven by a company driver or customer-driven for the occasional romantic long drive. Next level, instead of petroleum fuel vehicles make them electric. For many years there were a few concerns about electric vehicles : Battery charge duration, battery longevity, battery size, battery safety and source to recharge the battery. Coincidentally all these concerns can be addressed through a marvelous development by an American company named NDB who devising is a nuclear-powered electric battery technology which can be implemented in various forms for various applications, any application, big and small, and whose power source is a nuclear material called Carbon-14 whose wasted form ( from nuclear reactor waste ) is used as the source. You can read about the tech on the company's website
here.
Agriculture : Another big source of pollution. I intend to create a thread on this but I will just say here that fertilizer production, pesticide production, their production hazards and pollution and their usage pollution can be reduced greatly by reducing their production in the first place because we can move most of the agriculture model to Urban Farming and Vertical Farming and computerize these processes to make them efficient in water usage, reduce fertilizer usage and almost eliminate pesticide usage.
Housing : Use 3D Printing of houses and restrict houses to two floors and set among trees and gardens. Make the construction process resistant to fires and earthquakes. Spread the housing colonies horizontally in a township or city instead of vertically ( ten stories or fifty stories ). This will have an indirect, pollution reducing effect on the industries that provide the raw materials to construct houses. And will have the direct effect of making a city calmer and on its people also to be calmer. Remember to enable space for cats. Further calming and civilizing.
Computers : Read about Apple's forthcoming Glasses phone display. Well it really is a computer in its entirety. It will eliminate most of today's computer forms : cell phone, laptop, tablet, desktop, even many industrial displays I think.
Airplanes and ships : Electric mode of transport. Their power sources can be the NDB battery I mentioned. Elon Musk has been speaking of "electric jets" for some years. As to what they carry, the cargo or passengers will be reduced by the socio-economic and industrial changes occurring through the earlier things I mentioned, especially if most metal, plastic and concrete things are produced through 3D Printing. More pollution reduced.
What else have I missed ?
