There are an estimated 10 quintillion insects alive on Earth at any given time. That's 10,000,000,000,000,000,000 individual insects. But how many species are there, why do we need them, and what would happen if their numbers continued to fall? Dr. Alex Dittrich, a zoologist at N
There are an estimated 10 quintillion insects alive on Earth at any given time. That's 10,000,000,000,000,000,000 individual insects. But how many species are there, why do we need them, and what would happen if their numbers continued to fall?
Dr. Alex Dittrich, a zoologist at Nottingham Trent University, explains why these small creatures play such a big role in keeping our planet functioning.

Climate change can look very different at the scale of a forest, field or hillside. A new review shows how changes in vegetation and atmospheric conditions can cause local microclimates to warm at very different rates from the regional climate—and why this matters for understandi
