Ecologists are concerned with a number of environmental problems, including pollution, deforestation, habitat loss, and climate change. Pollution, in the form of air, water, and land pollution, can have devastating effects on ecosystems and human health. Deforestation is a major issue as it leads to a loss of biodiversity and contributes to climate change. Habitat loss occurs when ecosystems are destroyed or altered, which can lead to a loss of species. Finally, climate change, caused by the release of greenhouse gases, is having a profound impact on the planet, with potentially catastrophic consequences.
