Invasive species or pests are animals that end up in an ecosystem that is not their natural home. They pose a huge environmental risk to local ecosystems and food systems. But perhaps there is a solution and it might involve getting our taste buds used to the idea of eating them. Some of us are doing it already. One of the most popular items on one London menu is the pesky grey squirrel.

We also head to Australia to hear how feral camels have found an unlikely market with an immigrant community. And, why a lobster has Sweden and North America getting their claws out.
