biodiversity threatened, City growth and fast-growing of population destroy natural areas of new animals, endangered animal and plant. They do not care how small or big of it, how each species important in how the Earth works. Even though it protects water and soil from contamination, stores and recycles nutrients, breaks down and absorbs pollutants and helps areas to recover faster from disasters for the world. Biodiversity also provides people with medicine, food and air. Urbanization limits our access to these resources.
