Hempcrete

A wonderful material available worldwide, Hempcrete is able to act as an excellent carbon sink, has incredible strength and an almost unbelievable lifespan. An long story cut short. Hempcrete starts off as hemp-which is not hard to grow and is a remarkable material in itself, which uses an incredible amount of carbon dioxide before it is harvested. Then it is combined with lime and water to form a brick-like material. As a brick, it calcifies over time, essentially becoming a stone and acts as a great carbon sink. In which case the wall that is made of it becomes increasingly stronger-almost as strong as stone. It also gives it an incredible life span, about 600-800 years.Yes, they have built houses using it, but the majority of which is in Europe.Too bad it's incredibly expensive for North Americans (especially in the USA).

To summarize, hemp (other than being wearable, non-toxic, and absolutely wonderful) can be made into blocks of stone which harden over time and create structural strength so it lasts very long and is incredibly environmentally friendly and can be made available anywhere in the world that can grow hemp, and has lime or a suitable substitute.
