The wood for the trees

Can we reproduce jurassic vegetation?
Just the plants, not the dinos.. again..
Or :
Sequoia seems to be the biggest tree/ Paulownia seems to be the fastest.
- Cross them (just ask Frankenstein nicely).
Grow it.
Chop it.
Pylon it.
Like they did to make Venice
- new land for someone.
Jobs a good 'un.
Does that not make more sense than trying to pump gas into caves or creating a future where only the lucky few get to experience their self driving lithium chariots of fire?
What do you think?
