Garbage incinerator treatment of garbage will cause secondary pollution?

Hello, I'm happy to answer questions for you, you represent the personal view, you can take the piss not to pull too much, garbage incineration will cause secondary pollution, because garbage incineration will cause a lot of harmful gases into the air, resulting in the air it will be harmful to the gas, so I think that garbage is still centralized treatment is better, no matter what you're some of the crops in the countryside, or the city, some of the garbage ah need to be centralized treatment. Ah, or some of the city's garbage ah, are required to centralized treatment, if he casually burned on the spot, so it will be a hazard to the space, if everyone around the world to go to such a burning garbage, everyone is like this, burning some of the experts of the crop of orange, well, the harm to the air is not small, so that a lot of things are piled up, the accumulation of less into more. Then then words on the air caused by the pollution will eventually also be borne by us humans alone, so that we take good care of this earth, take good care of the environment it.
