Can Man reverse the damage we’ve done to the planet, and restore the Garden of Eden we inherited? Across the planet landscapes are degraded by overfarming, conflict, and desertification. But Africa is helping show that ruined landscapes can be repaired….while helping some of the poorest members of the human race. Back to the Garden reports from Rwanda, where the 1994 genocide had a little-known effect – degrading the land as well as the human spirit. It’s in Rwanda where scientists are now showing how to revive a ravaged landscape. They’ve learnt from the unique experiments of Dr Renee Haller, who’s shown how an old quarry, stripped bare even of the soil itself, can be restored to a fertile valley.
