Every four days there are a million more people on the planet. More people and fewer resources.

Writer, columnist, and professor, Alan Weisman handles the enormous issue of worldwide population development in his most up to date book. His movements to many nations in the quest for answers drove him to one x-factor that he accepts holds the way to a sustainable future. From climate change to energy, to agriculture, the population is the reality that transcends all other issues

Alan Weisman examines how we can reduce our collective human footprint to prevent us from stomping out of life any more species-including our own.

Alan Weisman's first thought-provoking novel, "The World Without Us," nevertheless shakes the balance of humanity with every infant being born and every drop of water being consumed.In his fresh book, "Countdown: Our Last Hope for Earth's Future?"Weisman discusses with us still here the idea of the Earth's future— plus a few billion more individuals. He dives into the very contentious and awkward subject of overpopulation from the opening pages and how it threatens our survival on our strained and overworked planet.

Countdown is a chaotic stew of big stories, bold ideas and conflicted characters—just like our people-packed planet.

 Ever since the 18th century, when Thomas Malthus raised the contentious and unpopular the topic of population control, there has been an ongoing debate in both the scientific and religious communities about how many people the planet can hold.

The Earth is aimed at the present birth rates in just a few centuries to reach a population of 10 million individuals. especially since scientists estimate that a sustainable population on our planet is only 2 billion. But the population of the world is eight billion. We use resources such as groundwater and fossil fuels at a much greater pace than they can be replenished. And wars are already being battled in areas of the globe over food, arable soil and water. Reading this book is a nice place to begin.

 Alan Weisman has been traveling around the world visiting nations and witnessing the effect of the population on the environment, living standards, and local society. He says tales from Palestine where an exponential leap has been made by the birth rate. And Japan, where there is a shrinking population and not enough youth to care for an aging society.

Water availability, clean or otherwise, is directly linked to the amount of individuals living on the planet, as is the growing need for food and resources. The flip side comes with these issues. The more resources our species consumes, the greater the impact on the millions of other species on Earth.

In its wide perspective of how distinct nations and cultures view our increasing population, this book was intriguing. Seeing how complex the issue is and how many individuals are working towards a solution was eye-opening. It was an opening of the eye and an undeniable call for action.
