In some ways, capitalism and a capitalistic mindset can be observed as a reason for negative externalities. In day-to-day lives, more negative externalities can be seen in the world. The whole global warming and climate change issue can be defined as an externality caused by humans' usage of electronics and electrical appliances, cars, industrial gases, garbage released into the environment, etc.
