On Earth Day, let's not forget the dirt. The planet is soiled with sewage, on land and sea. Our waste is the biggest marine pollutant there is, according to the United Nations Environment Program. In the developing world, ninety percent of sewage is discharged untreated into oceans and rivers, where its high nutrient content can suffocate the life out of seas, contributing to dead zones (405 worldwide and counting).
There are dead zones on land, too. Human waste contaminates environments all over the world, rich and poor. Imagine getting up at 4 a.m. in darkness, trekking to a nearby bush or field, and going to the bathroom out in the open. Imagine then being hit by a farmer who doesn't like you toileting in his field, or being raped by someone taking advantage of the dark, which you need to preserve your modesty.
The quarter of the world's population without access to sanitation - not even a bucket nor a box - don't have to imagine this. It's their daily reality. What's more, all that excrement lying around has deadly consequences. More children - up to 2 million a year, or one every 15 seconds or so - die of diarrhea, 90 percent of which is due to fecal contamination in food or liquid, than of TB, malaria or HIV/AIDS. Diarrhea is the world's most effective weapon of mass destruction.
That's the gloom. The good news is that it's solvable. And solving the world's sewage mess would be such a bargain that it should appeal to politicians holding the purse strings even in these straitened times. Investing $1 in sanitation reaps $8 in health costs averted and labor days saved. Look at it another way: not investing $1 in sanitation loses you $7.
Last year the World Bank calculated that poor sanitation cost Cambodia, Indonesia, the Philippines and Vietnam between 1.4 and 7.2 percent of their GDP. When Peru had a cholera outbreak in 1991, losses from tourism and agricultural revenue were three times greater than the total money spent on sanitation in the previous decade.
If numbers are too technical, let's get practical: Installing latrines and clean water supply in a typical village has dramatic effects. . .
