Biodiversity means the variety of all living things on Earth - different species, different habitats, and genetic differences within species. High biodiversity means lots of different species living together.
Check: Would a rainforest or a car park have higher biodiversity?
Every species has a role in its ecosystem. Biodiversity provides food, medicines, clean air and water. Ecosystems with high biodiversity are more stable - if one species declines, others can fill the gap.
Check: Why might losing one species affect many others?
Biodiversity is threatened by habitat destruction, pollution, climate change, invasive species, and overhunting/overfishing. These human activities have caused many species to become endangered or extinct.
Check: Name two threats to biodiversity.
Conservation protects species and habitats through nature reserves, breeding programmes, laws against hunting, reducing pollution, and habitat restoration. Everyone can help through small actions.
Check: What can you do to help protect biodiversity?
Biodiversity (biological diversity) is the variety of all living things. It includes:
Biodiversity is essential for life on Earth:
Conservation is the protection and careful management of the natural world:
The RSPB (Royal Society for the Protection of Birds) manages over 200 nature reserves across the UK. They protect habitats for rare birds like bitterns, which almost became extinct in Britain but have recovered thanks to wetland restoration. The RSPB also runs the Big Garden Birdwatch - the world's largest wildlife survey - helping scientists track bird populations.
The Scottish wildcat is Britain's rarest mammal - there may be fewer than 100 pure wildcats left. They're threatened by breeding with domestic cats and habitat loss. Conservation efforts include captive breeding programmes at Highland Wildlife Park and the Royal Zoological Society of Scotland, with plans to release wildcats into protected areas.
At Wakehurst in West Sussex, Kew's Millennium Seed Bank stores seeds from over 40,000 plant species - the world's largest collection of wild plant seeds. Seeds are dried and frozen to preserve them. If a plant species becomes extinct in the wild, seeds can be used to grow new plants. It's like an insurance policy for plants!
Many schools create wildlife gardens with native plants, bug hotels, bird boxes, and ponds. Even a small area can support bees, butterflies, hedgehogs, and frogs. This shows that conservation isn't just for experts - everyone can create mini nature reserves that help local biodiversity.

Wrong thinking: "Conservation is only about saving pandas and tigers." Correct: All species matter for biodiversity, including insects, plants, and fungi. "Unglamorous" species like earthworms and bees are often more important for ecosystems than large, charismatic animals.
Wrong thinking: "Biodiversity means different animals." Correct: Biodiversity includes all living things: plants, fungi, bacteria, and microorganisms are just as important. Plants form the base of food chains, and many species depend on specific plants for survival.
Wrong thinking: "I'm just one person - I can't help biodiversity." Correct: Individual actions add up. Creating wildlife-friendly gardens, reducing plastic use, buying sustainable products, and recording wildlife sightings all help. Many conservation successes started with concerned individuals taking action.
Wrong thinking: "Conservation means leaving nature completely alone." Correct: Conservation often requires active management. This might include removing invasive species, creating ponds, coppicing woodland, or controlled grazing. Sometimes human intervention is needed to help nature recover.
