Scales of environmental impacts in Antarctica. The area naturally experiences alternating wet and dry seasons. Biome is often referred to as ecosystem. Grassland ecosystems are morphing into scrublands and sand-scapes, all at the mercy of humankind. Erosion occurs when land is plowed; this is an unavoidable incidence in farming. The Mojave Desert encompasses 125,000 square kilometers in southern Nevada, western Arizona, southwestern Utah, and a quarter of California. Many ancient civilizations once flourished around the coast and on the islands of the Mediterranean, yet now many of these lands are deserts. Forests will be at risk of dying due to changes in temperature and moisture content, deserts will experience significant drought and famine, storms will become much more intense, and changes in precipitation will bring drought, famine, and an increased rate of species extinctions.
