Considering how many forests they destroyed throughout the series, Hashi should be very upset by the new generation
I mean seriously:
- Naruto/Gamabunta vs Gaara probably broke down a bunch of trees (it was even titled "Storm-like battle);
- Temari levels a forest vs Tayuya with a swing of her fan;
- Deidara C0's in the middle of a forest too. The explosion was 10 km radius;
- Itachi's Amaterasu during and after his battle with Sasuke burned a forest, too;
- Killer B levels a forest to fight the Edo Jins for convenience;
- And I'm pretty sure Madara's techniques, meteors and PS did some damage to forests.
Tell me if I missed anything O_O
