Asteroids are more interesting because they contain high concentrations of slightly denser metals of considerably more interest -- nickel, cobalt, etc. They can also contain much higher than normal concentrations of very heavy metals -- iridium, platinum, etc. -- that are rare in the Earth's crust because they're so heavy they tended to migrate to the core!
We have enough fossil fuels to change our climate, destroy the soil with too much fertilizer and build fishing trawlers until the oceans are empty.
This casual "the world has infinite resources to sustain unlimited human growth" is a bit 19th century and hasn't dated well.
Name a century without contrary characters and governments.
'LoL' and 'But Wat About' aren't considered responses.
Ocean resources are being depleted - it's simple enough to look up over fishing and a variety of reports on this from about the planet, not just direct overharvesting of fish, also reef destruction and other side effects from net dragging and industry that drive numbers down.
