Habitat loss is contributing to the permanent loss of species, the weakening of ecosystems, and is impacting the overall health of the planet.
Example:
While tree-clearing is a significant cause of habitat loss in Australia, other major contributing factors include altered bushfire frequency and the introduction of pest species that make habitats unsafe for native species or outcompete them. Meanwhile, on the Great Barrier Reef, the impacts of human-induced climate change are altering the habitats of corals, leading to large-scale coral bleaching. Over time, destruction of such habitats leads to reduced biodiversity and weakening of the Earth’s ecosystem.
