Habitat loss is a major cause of extinction and it is often the result of human activity.
Threats to wildlife today include deforestation, urbanisation, and changing land use. More intensive farming practices allow fewer native wild flowers, and the insects that feed on them, to survive.
Other species are threatened by drainage of the ponds and fens in their habitat. And climate change threatens habitats all over the world.
Here are a selection of species affected by these changes, that Museum scientists study, including plants like bindweed and the parrot waxcap, insects like the field cricket and hornet robberfly, and even a species of rat.
