it's not actually a lot of areas. this is the psychological effect of big numbers. you hear "one million acres" and think it's a big number, like when government spends "one billion dollars on school programmes", and it sounds like a lot, and your brain goes like "oh wow, i could never afford a billion dollars", but actually, if you divide that by 300 million people (population of the US), it's $3 per person ...

same as with land. it's like 20 m² per person on solar panels, probably less than some people's garage.
