A synthesis of a large number of biological studies has shown that humans are responsible for high levels of biodiversity loss (Guardian 26 March).
This decline is driven by a number of factors, namely habitat change, direct exploitation of resources, climate change, invasive species and pollution. This includes use of pesticides, for example.
A Professor of Ecology noted that many species have key roles, such as pollination and seed dispersal. They need larger populations and genetic diversity so they can continue to evolve and perform their functions that keep the ecosystem going.
Of course it is capitalism, with its profit motive and drive to expand, that is responsible for such degradation.
