How's this for a conspiracy theory?
Every year the haze returns with a vengeance. The source of this malevolent miasma? Peat fires in Indonesia. When the haze comes, Malaysians are advised to stay indoors, or can end up suffering from, among other things, eye infections, breathing difficulties and skin irritation. Now what if this isn't an accidental occurence / natural disaster / yearly phenomenon? What if... Indonesia is trying to smoke us to death so they can take over our country without losses on their side? Has nobody ever questioned why tens of thousands of Indonesians come to Malaysia to work, and only a few thousand ever go back home... I tell you, their trying to take over our lives from within... The next time the haze hits, it will be worse... There's going to be something in it that numbs our brains and makes us think it's ok, it happens every year, I just need to wear a mask outdoors and spend more time indoors... Then they will strike, like something out of THE FOG, only this time it won't be shambling zombies, no, it will be Indonesians who look just like us walking out of the haze, and every year there will be more of them and less of us... after a few more years, we would all have been replaced, and we'll all have names like Penggunawan Marihantok or Elsi Elwai. Shudder...

(No Indonesians or Malaysians were harmed in the production of this admittedly fictitious epic tale of horror, displacement and identity crises)
