Pollution: Cambodia’s Silent Killer

December, 2016. I’m making my way to Bangkok, from Sihanoukville, Cambodia. As the bus shudders to a halt at the Poi Pet border, I disembark, hauling my heavy backpack over my shoulders & walking the short distance to the immigration office.

As I walk, my flip flops flick brown sludge up the back of my calves. Beggars with missing limbs hold their trembling hands out for anything they can get. Street food vendors watch lazily as flies buzz over raw meat, creating a stench as it begins to rot in the sun.

I look down & see a pink umbrella, clearly made for a small child. Propped up in the dirt road with some rocks, it provides shade to the two sleeping bodies underneath – a boy of about 5, cuddling his naked baby sister.

30 minutes later, as I exit the immigration office & emerge into the Kingdom of Thailand, I am shocked.

Not more than 100 metres have passed but I feel as though I am in another world.

The filthy dirt track has been replaced by pavements and a tarmac road, free from potholes and dust. The beggars have vanished & the foul smelling garbage that littered the ground I had just been walking on is nowhere to be seen.

Having become so accustomed to life in Cambodia, I’d almost forgotten that it isn’t actually normal to find open sewage, garbage and giant rats on every street corner.

 It is easy to dismiss the problem as being the result of a ‘stupid, uncivilised’ nation; to look down on a culture so savage that it lives in its own waste, seemingly without a care in the world.

In the West, we have the importance of sanitation drilled into us from infancy. We are told to wash our hands before eating, throw our rubbish in the bin & DON’T EAT THAT IF IT’S BEEN ON THE FLOOR! It is second nature to us to drink clean water, flush the toilet & wash our hands after touching raw chicken. We keep our foods in the refrigerator, our litter in the bins & our excrement safely down the toilet.

But what if we didn’t have a toilet that disposed of our waste?

What if, like up to 85% of Cambodians*, our toilets were nothing more than squat holes with a pail of water & a bucket to flush?

What if, as with up to 69% of Cambodians, we didn’t have access to clean water, & had no choice but to drink the water that others defecate into?

What if we were never educated about the importance of sanitation?

Would we instinctively know that unclean living conditions breed disease?

Aid workers and health officials don’t think so.

To begin to understand why Cambodia is so polluted compared to its neighbours, we must first have a deeper understanding of Cambodia’s recent history. When Pol Pot & the Khmer Rouge evacuated the city of Phnom Penh at the start of their bloody reign of terror, nobody could have predicted that the city’s new residents, years later, would be those from the countryside.

The capital’s new inhabitants were people that had no idea how to live in a city. They didn’t know that if you throw a plastic wrapper onto the ground, Mother Nature won’t take care of it in the way that she takes care of apple cores & banana peels in the countryside.

They didn’t know that their new drainage systems would flood in the rain & send pungent streams of sewage down the streets of their new city. They were not to know that their rubbish would not just disappear any more, & that it would begin to attract rats and flies and disease instead.

Cambodian people live the way that they have always lived.

Because survivors of the Khmer Rouge were not educated, they do not see education as a priority for their children. Because of this, Cambodian people remain unaware that the reason their children itch & cough is due to their poor living conditions. Instead,they blame their ailments on spirits and demons, & are more likely to trust a fortune teller than a teacher.

Every year, squatters still come in their thousands to live on the riverbank of Phnom Penh. They build wooden homes on stilts & throw all their waste directly into the river underneath them. Families for miles catch their food, wash their clothes & bathe their children in this putrid brown water. They don’t make the connection between the dirty water & their child’s diarrhoea, the leading killer of children in Cambodia.

When a Khmer gets sick, they will refuse to go to Western clinics.

Instead, they rely on traditional remedies. They scratch tiger balm into their skin, leaving angry red marks across their backs & chests, adamant that their illnesses will be cured. A cigarette burn to the stomach is thought to cure stomach aches, & for everything else, there’s prayer.

For those Cambodians that DO seek proper medical attention, the odds are stacked against them.

Doctors, surviving off meagre salaries, are almost always corrupt, & up to 25% of malaria drugs sold in the pharmacies are fakes. Indeed, drugs that are banned in the West due to their dangerous side effects are pedalled in Cambodia because they are cheap. Antibiotics are seen as the answer to everything, & it isn’t unusual for doctors to see seriously ill patients who cannot be treated because they have built up a resistance to them.

It doesn’t help that the Khmers are so nonchalant towards death.

After seeing a quarter of their people butchered less than 40 years ago, the Khmers still see death all around them, from AIDs, moto wrecks, malaria, grenade accidents, stabbings over minor disagreements, dengue fever & more. Around 50% of Cambodians children have diarrhoea, all or them will develop up to 7 respiratory infections before the age of 5, & 1 in 8 will die before their fifth birthday.

When you combine with this with the fact that the life expectancy is just 54, that the maternal mortality rate is among the highest in the world, & that there are only 0.3 physicians per 1000 people, it’s hardly surprising that death is not something that Cambodian people fear.

As a result of this apathy regarding human life, lack of education & poverty, many Cambodians leave diseases untreated, leading to disabilities that could easily have been prevented. These disabilities create more unemployment, forcing people to beg on the streets, living in even filthier conditions, & getting sicker and sicker. Waste builds up, attracting rodents & flies, creating more sickness, & so the cycle continues.

If Cambodia is ever going to rise up & be the beautiful, prosperous country that it has previously been, it needs to start from the bottom.

Basic education about hygiene & germ theory in schools, volunteer projects to clean up the city streets & improved drainage systems will all go some way to restoring the country to its former glory. Efforts to recycle will help stop Cambodia’s slow suffocation from plastic.

Just as importantly, Westeners need to lead the fight against pollution in the Kingdom. 

It is Western expatriates, with their education & their money, who can lead by example in this developing nation. Every Western traveller can do their bit by reusing plastic bottles, not littering and taking part in beach clean-ups & conservation projects.

We have the power.

It is time we used it.
