Mass Extinction

Some 66 million years ago, a meteor crashed [blank] the coast of Mexico's Yucatan Peninsula, marking the end of the age of dinosaurs. It was a mass extinction event and it was devastating. Mass extinction is a short period of geological time in which a high percentage of biodiversity or distinct species dies out. Unlike previous extinction events that were caused [blank] natural phenomena, the sixth mass extinction is driven by human activity. The biggest driver of destruction is how we use the land and the sea. This includes the conversion of land cover such as forests and other natural habitats [blank] agricultural and urban use. Agricultural expansion is the main driver behind deforestation, with animal farming being a particular driver of forest degradation and forest biodiversity loss. The natural world [blank] also affected by the climate crisis. Species and ecosystems around the world, especially the most vulnerable ones, are affected by the rise of greenhouse gas emissions. Mankind's emissions of greenhouse gases [blank] warming up the atmosphere and subsequently everything on Earth.
