How human activity has impacted the effects of the tornado?

Answer 1

Some have proposed that global warming caused by humans may be increasing tornado activity. However, so far there is no substantial evidence of that. However,other activities, while they have not impacted tornadoes themselves, have increased our vulnerability to them. Building trailer parks in tornado prone areas is one thing. Even a relatively weak tornado can cause major damage in a trailer park, and nearly half of all tornado fatalities occur in mobile homes. Additionally, urban sprawl is creating bigger targets for tornadoes, and thus more potential destruction. A tornado this year may tear through a neighborhood that was open country 30 years ago.
