They are being degraded, with examples including the deforestation of the Amazon and the disappearance of salt marshes and mangrove swamps , which remove large amounts of carbon. The way we use the land and sea is one of the biggest drivers of biodiversity loss . Since 1990, around 420 million hectares of forest have been lost through conversion to other land uses. Agricultural expansion continues to be the main driver of deforestation, forest degradation and forest biodiversity loss . Other major drivers of species decline include overfishing and the introduction of invasive alien species (species that have entered and established themselves in the environment outside their natural habitat, causing the decline or even extinction of native species and negatively affecting ecosystems). These activities, UNEP has shown , are pushing around a million spec...
