Pollution! It’s a trendy but gloomy word designating something most people try to avoid contributing to, but not many folks realize what causes it and how it affects them.
Humans and technology are the primary contributors to ALL pollution, either inadvertently or deliberately.
Manufacturing processes; obtaining raw materials and resources (mining and forest destruction, etc.); and technological ‘advances’ – more often than not – are the major contributors along with vehicular exhausts and ever-increasing road traffic.
