In
developing countries, where trash collection is still handled manually, there
have been several news stories done of people who actually live in landfills so
that they can collect salvage material that they can sell to junk shops.
However, a lot of what people throw away can be very toxic and unsafe for
direct human handling, and in some cases, they can cause diseases if not
properly handled, especially if they come from industrial sources. Although
recycling can help reduce our garbage problem, it should not come at the cost
of human lives.
Keeping
cities and towns free of garbage is extremely important not just for the
obvious purpose of sanitation, but also because waste left on the streets might
end up clogging drainage systems that would eventually cause flooding. Today,
heavy-duty street sweeping vehicles and other types of cleaning equipment are
used to hasten jobs that people traditionally had to do with brooms and hoses, making
the job easier and more structured than before.
However, as
cities expand and the population grows, the volume of garbage produced every
day also increases. Fortunately, technology is constantly working on solutions
for quicker methods of collection and disposal,
and if developing countries can secure the funding necessary for these
machines, perhaps they can improve their city cleanliness enough such that no
more children have to develop diseases such as malaria or tubercolosis.
