Cae por su peso

[ROBINDESBOIS]

when something is very evident and needs no explanations, we say cae por su peso . IS there anything similar in English?

Ejemplo:

- Cómo sabes que no se pueden plantar árboles encima del tunel de la M30
- cae por su peso, porque las raices lo destruirían

Maybe:
stands to reason

You know we can't plant trees above the tunnel.
Well, that stands to reason, the roots would destroy it.
