Large number of species and abundant resources are the two characteristics shared by ecosystems that have high biodiversity. Habitat loss and pollution are the two specific human activities that result in a loss of biodiversity. Habitat loss occur when the human removed all the trees and vegetation in order to made the land for cultivation of crops or building houses. Pollution is the main cause that leads to loss of biodiversity. Human activities release gases which pollute the environment and leads to loss of biodiversity. Avoid activities that causes pollution and used of barren lands for cultivation and infrastructure. Climate change is naturally occurring factor that could lead to a loss of biodiversity. Biodiversity boosts ecosystem productivity and natural sustainability.
