Book Description
Do you know silica, the tetrahedra of silicon and oxygen constituting the crystals of New Agers and the desiccant in a box of new shoes? It's no mere mundane mineral. As chemically reacting silicate rocks, silica set off the chain of events known as the origin of life. As biomineralized opal, it is the cell wall, skeleton, spicules, and scales of organisms ornamenting numerous lobes of the tree of life. Cryptocrystalline silica made into stone tools helped drive the evolution of our hands and our capability for complex grammar, music, and mathematics. As quartz crystals, silica is impressively electric and ubiquitous in modern technology (think sonar, radios, telephones, ultrasound, and cheap but precise watches). Silica is inescapable when we take a drink or mow the lawn and it has already started to save the Earth from the carbon dioxide we're spewing into the atmosphere. This book tells these scientific tales and more, to give dear, modest silica its due.

Book Description
The ocean allowed life to develop on earth billions of years ago, it is vital for all of us and it will guarantee the future of humanity. The ocean is vast, deep, harsh and somehow “rebellious” to reveal its secrets and hence, there is much that is unexplored and not yet understood. Scientists need to study the ocean to better understand its functioning, its properties, as well as how it shapes our environment and impacts us. For example, do you know what the role of the ocean is on weather and climate? There also remains so much to explore and investigate as diverse oceanic resources (fish stocks, bio-molecules, renewable energies but also minerals, oil and gas…). How can we make sure that our use of these resources is respectfully done and sustainable and how can we minimize our impacts (e.g. pollution, acidification, deoxygenation) on the ocean as our human population increases? In this Collection of Frontiers for Young Minds, ocean scientists from various disciplines explain recent discoveries or fundamental concepts. They share their knowledge and motivations and give insights into innovative tools and methods used to better understand our ocean. The Collection targets a large range of oceanic environments from the open ocean to the shores, the surface to the abysses including specific areas like coral reefs. It also targets the connections of the ocean with its interfaces (atmosphere, ice, coast). It seeks to cover marine disciplines that range from physics to chemistry, from biology and genomics to biodiversity and ecology, and from economy to conservation and policies. Finally, it encompasses a great variety of scales, ranging from the diel to geological time-scales, from loco-regional to global scales and also from the tiniest cells to the biggest living animals on our planet. The United Nations have declared the 2021-2030 period as the “Decade of Ocean Science for Sustainable Development”, stressing the urgent need to approach fundamental issues related to the ocean and the future of humanity on well sounded scientific grounds and knowledge. The oceanic sciences are indeed undertaking a revolution thanks, in particular, to robotization and the massive intrusion of big data and artificial intelligence. This Ocean Collection aims to accompany this evolution to provide information to young readers that will help them to increase their understanding of the ocean and its central role in nature and our lives. We hope to empower them to make informed decisions in these challenging times and to engage to protect, study and enjoy its richness.

Book Description
Earth is, to our knowledge, the only life-bearing body in the Solar System. This extraordinary characteristic dates back almost 4 billion years. How to explain that Earth is teeming with organisms and that this has lasted for so long? What makes Earth different from its sister planets Mars and Venus? The habitability of a planet is its capacity to allow the emergence of organisms. What astronomical and geological conditions concurred to make Earth habitable 4 billion years ago, and how has it remained habitable since? What have been the respective roles of non-biological and biological characteristics in maintaining the habitability of Earth? This unique book answers the above questions by considering the roles of organisms and ecosystems in the Earth System, which is made of the non-living and living components of the planet. Organisms have progressively occupied all the habitats of the planet, diversifying into countless life forms and developing enormous biomasses over the past 3.6 billion years. In this way, organisms and ecosystems "took over" the Earth System, and thus became major agents in its regulation and global evolution. There was co-evolution of the different components of the Earth System, leading to a number of feedback mechanisms that regulated long-term Earth conditions. For millennia, and especially since the Industrial Revolution nearly 300 years ago, humans have gradually transformed the Earth System. Technological developments combined with the large increase in human population have led, in recent decades, to major changes in the Earth's climate, soils, biodiversity and quality of air and water. After some successes in the 20th century at preventing internationally environmental disasters, human societies are now facing major challenges arising from climate change. Some of these challenges are short-term and others concern the thousand-year evolution of the Earth's climate. Humans should become the stewards of Earth.
