Alarming declines in the number of insects, vertebrates and plant species around the world have raised fears that we are in the midst of a sixth major extinction that could cause a collapse of the natural ecosystems we rely upon to survive.
This month, Horizon explores the global challenge of biodiversity loss. Many experts believe we are in the midst of a sixth mass extinction, where human-caused factors such as land use and pollution are causing a decline in biodiversity – something that threatens the future of our own species. We speak to British ecologist Professor Georgina Mace about how bad the situation is and what we can do about it. We explore marine ecosystems, where species relocation outpaces that of terrestrial populations, and examine how we can help these environments adapt. We also look into the link between food insecurity and biodiversity degradation, and find out what’s in store for bees – our pollinators. Finally, we investigate the services nature provides for people – from cleaning our water to acting as a carbon sink – and ask whether putting a value on natural capital could help save it.
Studies investigating whale-watching boats and the inner ears of marine mammals could soon provide new insight into the effects of noisier oceans on cetaceans – dolphins, whales and porpoises – who depend on their hearing for navigating, finding food and communicating underwater.
Understanding the progression from the stepping reflex to independent walking could help find new therapies for children with cerebral palsy (CP) – a movement disability caused by brain damage before, during or shortly after birth.
In the solar system’s early days, a first Earth is thought to have been pulverised by a planet that scientists call Theia. We don’t know what it was made of or where it came from, only that it may have been the size of Mars. The powerful collision destroyed both planets so completely that scientists can only guess what they were like.
As a child, you almost certainly at one stage spent hours watching ants move about from their nest. Maybe you dropped a piece of food and watched as a group of ants came and picked it up, carrying it home in an impressive display of cooperation.
Tuberculosis is the most common cause of death from an infectious disease.
Computer modelling will also help optimise management techniques.
