However there are a lot of entrenched interests that would be harmed by any large-scale attempts at fixing earth. Even if you paid for it out of your own pocket and brought your own engineers, your attempt at fixing Earth would face strong opposition. Meanwhile barely anyone would oppose your attempt at improving Mars.

The article is however spot on that terraforming Mars looked easier 30 years ago than it looks now, with all the new knowledge we have from Mars rovers. Now any "realistic" plan would be millions of people living in pressurized habitats and venturing out in suits, not billions walking on the surface in t-shirts. Closer to what we see in The Expanse than to what we dreamed up in the 80s and 90s
