Our planet has followed an evolutionary path determined by geological forces since its origin about 4.5 billion years ago. Throughout its evolution, the Earth has undergone significant changes in its crust and atmosphere. With the onset of the Industrial Revolution around 1750, a new agent of change has been added to the geological transformations. Rapid population growth (we are 7.3 billion people today, and we will be about 10 billion in 2050) associated with the excessive use of natural resources has brought several of the health indicators of our planet outside safe boundaries. Especially after 1950, human development and its implications on terrestrial ecosystem have grown exponentially. Currently, a large fraction of the continental areas without ice is occupied for human activities such as agriculture, grazing pastures, and urbanization, among others.Downloads
