"Conventional wisdom is that wild animals are being wiped out. But conventional wisdom skips some important details. Wildlife is rebounding. Not everywhere. Not every species. But a handful of wildlife populations have reached numbers unimaginable in a century. Red deer in Europe, bison in North America, humpback whales in the Atlantic. They have all seen their populations explode. They are back from the brink, numbering in the tens, or even hundreds, of thousands. Their return thrills those who have rooted for their recovery. It terrifies those who grew comfortable without them. This book tracks-and tries to understand-these dramatic rebounds. It shines a light on species returning to forests and farms, prairies and oceans, rivers and cities. It asks how these transformations can be happening and what they have to teach"--

"This book explores how tools of the Digital Age might be mobilized to solve our most pressing environmental challenges, from climate change to biodiversity loss. It argues that digital technology might accelerate environmental sustainability and that engaging with environmental issues may transform Big Tech for the better, if the sector successfully addresses spiraling energy use, pollution, privacy and surveillance issues"--

The Arab Republic of Egypt enjoys a vital strategic location. Its northern border is the Mediterranean Sea, and its eastern border is the Red Sea, which give it a special significance from the bio-diversity point of view as a coastal zone, and as a sensitively diversified ecosystem. The shoreline of the Arab Republic of Egypt is about 3,000 km long. It is about 1,150 km long on the Mediterranean and about 1,850 km long on the Red Sea, which are connected by the Suez Canal, which is about 193.30 km in length. The three water masses are different ecologically and are experiencing wide range of pressures due to, eutrophication, coastal development, aquaculture and climate change. These conditions resulted in several species of seaweeds that adapt to these pressures and expand their living boundaries while others may fade away. Accordingly, the study of seaweeds biodiversity in the Egyptian marine waters is of great concern globally and constitutes an important element of global changeresearch.The present book entitled Biodiversity of Seaweeds in the Egyptian Marine Waters summarizes our current understanding of the biodiversity of seaweeds in the Egyptian marine waters. It is a timely publication based wholly on primary data which were collected through extensive field studies conducted over the years covering the marine Egyptian waters and culminate the efforts of the Egyptian phycologists. The book contains high-quality images of some species in their existing habitats. This book gains critical importance from the fact that the Egyptian marine environment is witnessing rapid development, which will no doubt have a bearing on the coastal environment ¿ and the baseline data on seaweed biodiversity would be useful to understand changes that may arise from physical changes in the environment as also pollution load and climate change.

The book deepens understanding of biomass sources and technologies used for cooking worldwide. It contributes directly to the creation of policies aimed at the mitigation of climate change.Historically, wood is considered humanity's first source of energy. Even after decades of use and industrialization processes, it is still considered the most important single source of renewable energy. About a third of the world's population is energetically dependent on wood for cooking and/or heating. Recently, the Covid-19 pandemic made it impossible to purchase fuels such as liquefied petroleum gas (LPG), forcing families in financial difficulties to opt for cheaper and more accessible sources of energy, such as wood and vegetable coal. This has been the picture of many families around the world and negatively impacts the environment and energy security. Considering that there are still many wood residues that are wasted and that tropical forests need to be conserved, knowledge aboutthe energy use of wood residues is also essential. This is even more relevant when considering the significant volume of biomass coming from the sustainable management of the largest tropical forest in the world, the Amazon Forest.The book considers which wood variables should be taken into account when thinking about energy generation, how do food cooking technologies contribute to potentiating pollutants emissions, and how can these harmful effects be mitigated. It describes the chemical composition of biomass and the chemical compounds released during its burning, as well as their impacts on the environment and human health. It also presents the influence that technologies used in food cooking have on pollutant emissions and which alternatives can be used, such as the use of solar energy.

This book relates one of the most representative species of Patagonian wildlife, the guanaco, to human societies across time, and explores how that relationship has changed over time due to different land uses and productive interests. The book provides information to understand these interactions, and contextualizes the current situation of this species. In some cases, it proposes possible solutions to conflicts, and also shows ongoing activities aimed at sustainable use and conservation. The audience for this book includes researchers, graduate students, policy makers and conservation and rural development professionals. In addition, it will serve as a tool for application authorities and field technicians on the use and conservation of wildlife, to define management actions for this species. 

This book opens up a critical dimension of energy transition taking in account multidimensional challenges on economic, social and environmental fields. The book discusses the trends in the field of energy transition and evolving practices adopted by public authorities and companies for betterment of environment and society. The editors (4) identify directions and challenges involved in the energy transition. The novelty of this book is the multidisciplinary approach, being presented the economic, social and environmental challenges involved in the energy transition. The energy transition is accompanied by a complex process of changing attitudes and behaviors of energy consumers and producers. The consequences are profound not only economically and environmentally but also socially, renewable energy being a solution for energy poverty reduction and development of rural communities. Therefore, certain social and environmental problems generated by energy poverty are solved by using renewable energy. Moreover, the complexity of the phenomenon is presented not only in terms of the analysis of the main sources of renewable energy but also the ethical aspects involved in the use of sources such as biofuels. In the case of this source, the main problem is whether the use of certain agricultural products for the production of biofuels threatens food security, especially in rural areas.All categories of stakeholders must show responsibility and get involved in this complex process which requires a remarkable technical and financial effort. The energy transition can offer innovative solutions through which the impact of economic activity on the environment is minimized, and in this way, industrial ecology achieves its objectives to support sustainable development. The demands imposed by industrial ecology must shape not only the behavior of oil and gas companies but also of entities involved in the production and consumption of renewable energy. Given the negative externalities generated, companies in the fossil fuel sector have become increasingly socially responsible, their social and environmental performance (non-financial) being presented in detail in the annual sustainability reports to inform stakeholders. Therefore, this book is an important read not only for scholars, but also for those who are interested in ensuring an environmentally sustainable future taking in account energy transition challenges.
