Broadly speaking, biodiversity is the diversity of living things, the sum of species.
It is this diversity, this multiplicity, that is the basis of human well-being. It provides life-giving oxygen, drinking water, food, etc.
Farming has a direct impact on the diversity of life, and if we mismanage the land we are given, in the long run our quality of life suffers.
Today, the number of living species is decreasing day by day, with thousands of animal and plant species disappearing from our planet every year.
We humans are the main cause of this increased extinction.
