Concerning energy, Lomborg asserts that oil is not being depleted as fast as is claimed, and that improvements of technology will provide people with fossil fuels for years to come. The author further asserts that many alternatives already exist, and that with time they will replace fossil fuels as an energy source. Concerning other resources, such as metals, Lomborg suggests that based on their price history they are not in short supply. Examining the challenge of collecting sufficient amounts of water, Lomborg says that wars will probably not erupt over water because fighting such wars is not cost-effective (one week of war with the Palestinians, for instance, would cost Israel more than five desalination plants, according to an Israeli officer). Lomborg emphasizes the need for better water management, as water is distributed unequally around the world.
