Houston and Tampa are pretty similar in number when it comes to ecological disaster potential.
A big difference is the size of the population that lives in the danger area because of Houston zoning. It's the 4 largest city in the US by population with a massive greater city area
Yea, you're right, the 3 million people living in the tampa metro area, their lives dont matter.
Noting there is a difference in population and potential impact is not the same as saying X million lives don't matter.
