It is only natural to listen to natural calls. In under -developed nations , when one feels like answering the calls of nature, one must not look inward the house, rather one must look without the house  to relieve oneself. It is because in under-developed nations( even though they might like to call themselves Developing nations) people would rather erect one more rule, or invest in something else than erecting a toilet. It's a common scene, especially in the outskirts of an urban area(sometimes coinciding with slums) that we find pathways and roads littered with human waste. It doesn't only make the environment very unpleasant and dirty, it also sets free malignant virus and bacteria which cause so many diseases, some of them being even fatal to the people, especially children living around that area. Moreover, it is carried to faraway places through the tyres  of the vehicles and even the human feet. We must remember that Polio virus is spread through human waste released in open spaces. children fall victim to these viruses and suffer for the whole life.


It is not only the human waste that we have to take care of. In a country like India where animal husbandry is a big thing, even animal waste needs to be managed while we have not found any serious problems with cow dung( which in fact are used to make compost), the wastes of pigs are a notorious source of many forms of human sickness. Pig- wastes , mingled with mud and water spread in a large geographical area, cause serious threat to human hygiene. Here we cannot forget about the wastes created by the stray dogs (which are in a large number in India).

In short, waste created by living beings like humans and animals need a lot of management to keep the environment safe for both the humans and the animals.
