Another global summit - COP15 – has concluded in Canada.

It focused on biodiversity, which is the variety of all living things on earth.

Activists, charities and ministers came together hoping to find solutions to protect and save forests, wetlands and water bodies before it’s too late.

Recent studies have suggested that nearly a third of all species are currently endangered due to human activities such as logging, climate change and farming.

So how bad is the situation and what needs to be done to protect biodiversity?
