I make cardboard furniture

I teach you how to be happy

we set up schools in the most unlikely places

The untouchables I help are no longer destined to clean human excrement

I created the world's simplest toilets

I restore women who have been destroyed by rape

I created Clean Up Day

I offer in-home refills for my own line of organic products

I build houses out of hemp concrete

I converted a Boeing 747 into a hotel

My technology reduces shipping emissions

I created a blanket coat for the homeless

I make edible food packaging

I created a universal language for the deaf community

I make soap from used cooking oil

I'm building sustainable earthen roofs

I'm fighting the blood mafia with my free donation network

My invention revolutionises personal mobility

My pencils make plants growing

We transformed a bunker into a hotel
