Cars and factories give off fumes that pollute the air, but they make life easier for humans, creating goods and taking us places faster.

They may not understand how to use it
Communities can be negatively affected by technology because it could ruin their culture, for instance the tribes in South America. But some communities are positively affected by technology because it connects countries so you know whats happening and makes security tighter.

Workers are getting placed by machines:-)
