Environmental Challenges Facing the Current Generation
What are the most challenging environmental issues that will face humanity over the next 50 years? And what are the best ideas for options in the face of these challenges? What are some companies doing to mitigate (reduce, reuse, and recycle resources) the problems on a local level? These and other issues and questions will be approached in this paper.
The Main Environmental Challenges
While there is no one single most serious environmental challenge that all scholars, scientists, researchers, policy makers, journalists and others agree on, any cursory research into future environmental challenges and issues for Planet Earth will turn up the alarming and well-documented consequences of climate change. Of course climate change is not just a future issue but very much a current worry for citizens, scientists and policy makers. Many other critical issues are related to global climate change, including the population explosion.
Population: Indeed, much of the available literature on future environmental challenges reflects that earth's escalating population -- which is expected to reach 9 billion people by 2050 -- will have a great deal to do with the quality of (and sustainability of) the environment in the future. Jim Foley is the director of the University of Minnesota's Institute on the Environment, and he asks the pertinent question relating to population growth: "Can we feed our growing world while still protecting our planet's environment?" (umn.edu). His point is that people in emerging economies -- many of them Third World countries -- "…increasingly want to eat Western, meat-rich diets," and that portends a need to double the world's food supply in the next forty to fifty years (umn.edu).
The need to provide food for a projected 9 billion people is itself a great concern because as Foley reports, thirty percent of the greenhouse gases -- which are known to contribute to the warming of the atmosphere -- are produced from "human agricultural activity" (umn.edu). It is probably not well-known by the general public that greenhouse gases produced by agricultural activity are more than "all our...
Environmental Case Study (Alberta's Oil Sands) Alberta's Oil Sands represents one of the international environmental problems facing Canada and close to seventy countries across the globe. Albert's Oil Sands proves to be a new course of political conflict within the setting of Canada and at the international level. Oil Sands development is responsible for rapid economic growth of Alberta. This creates ethical or moral dilemma because there is a massive risk
Firstly, it is crucial to raise awareness and to actually make people listen, care and then act accordingly. Everybody needs to understand that the environment should be everyone's concern because it truly affects all of us as we are all inhabitants of the same planet. This is achieved through information which in turn, is achieved through long-term campaigns which have the mission to reach as many people as possible.

Cassandra Believing Cassandra: An Optimist Looks at a Pessimist's World is a book about the environment, its blunderings, and the sustainability of our world. This is a book for people trying to understand our intricate world and how it is failing and succeeding. I found the approach this book takes to the environment to be entertaining and worthwhile, for not just the information it provides, but the fresh perspective it
Environmental Science Environmental fundamentals Defining environmental science: The quest for sustainability Environmental science or environmental studies are defined as the "study of a range of environments, from the bodies we live, to the physical structures, institutions and industries we build, to the politics, languages and cultural practices we use to communicate, and to the earth and its complex multitude of animals, flora and bio-physical elements and processes" (What is environmental science, 2012, York
Vertical Farming-Opportunities and Challenges for Singapore There has been much talk surrounding the environmental issues of food production, with many now suggesting the city is the ideal place for growing food to cater for rapidly expanding urban populations. In Singapore, small-scale examples of this are emerging, such as Changi General Hospital and the Tanjong Pagar apartment complex. This dissertation will examine the Vertical Farming movement, and look at the opportunities and
