This book focuses on the Earth¿s carrying capacity to service the needs of its human populations as well as preserve the ecosystems that provide natural resources that sustain life and support human activities in 2020 and later in the century (2050 and beyond). It addresses the two principal factors that challenge the limits of the carrying capacity: growing populations/demographic moves and global warming/climate change. It also covers the effects that these factors have on water availability, food security, sanitation and natural resources. The status of these basic needs that sustain life and societal activities with respect to population increases and global warming driven climate changes are discussed on two time frames. One with respect to the 2020 and the other with measured and computer guided projected future impacts later as the century progresses to 2050 and later, Attention is given to Africa, Asia, and somewhat for South America because of their projected increases in population.The purpose of the book is to provide those in decision-making roles and those that advise them with a sound set of facts and figures to think about to support their decisions/actions. A secondary purpose is to present data that stresses the need to act now, firmly and with investment to plan to adapt to changing conditions rather than wait until forced to do so. The book also discusses how the COVID-19 pandemic has affected the world¿s societies and how they have reacted. The book will be of use to students in first/second year of college/university programs in Environmental Sciences/Studies, demographics, and ancillary fields such as agriculture science, urban/land use planners, political science, public health, and consultants at academic and professional levels.

This book discusses growing populations emphasizing both regional and national situations. For the first time topics including population growth, ecosystem chemistry and development planning have been melded into a single text.

This book discusses the identification of, solutions to, and management of threats to high population coastal cities and their seaports from global warming, climate change and endemic hazards.

This book discusses existing and future global problems of physical, chemical, biological and societal origins faced by increasingly populated cities and mega-cities, and options to mitigate or eliminate them.

This book advances a three-step program for mitigation of natural and anthropogenic hazards, addressing mitigation economics and funding possibilities to meet the needs of at risk countries that lack the financial resources to invest in disaster reduction programs.

This book brings together in a single volume a grand overview of solutions - political, economic, and scientific - to social and environmental problems that are related to the growth of human populations in areas that can least cope with them now.
