The Earth is an isolated planet that contains all that you love and know. As change comes in the form of events in the near and distant future, the Earth will undoubtedly transform to accommodate these changes. To adapt, you will need to study the scientific methods to bring about a better place for this unknowable future. Science is not a doctrine to believe blindly, but a process to investigate and propose solutions to problems as they arise. Throughout this course, you have been introduced to the wonderous planet that you call your home, its gas atmosphere, liquid oceans, rough terrestrial terrain and deep interior of rock and heat. You’ve learned a little about the lifeforms, an oddity that makes the planet so unique in our solar system, as well as the rise of intelligent creatures such as yourself, a species that has come to dominate the planet. The Earth’s story is mixed with the individual hopes and dreams of various people who have investigate the wonderous planet they live upon, to understand the reality of existence through observation and ardent collection of data. Theories and ideas supported by experimentation and testing. What you take from this course will guide you in further explorations of these topics, beyond what a simple online class is able to convey. This final chapter, this final module, will leave you with a sense of direction of where to go and how to conducted your life to more critically think about the world around you.

## Don’t Believe Everything that is Told to You

In the modern world, the goal of any propagandist or advertiser is to gain your attention. The rise of conspiracy theories, misconceptions, fallacies of thought rise out of your consumption of the media that is feed to you. Images of outrage, violence, hatred, death and despair carry a heavy emotional impact that can be a powerful motivating force, used to elicit reaction and attention from you.
In the modern world, it can be difficult to determine what reality is, and what is propaganda or false ideas or mistaken concepts. Every idea cannot be tested by an individual investigator. You may not have access to the equipment, materials, animals, test subjects or data necessary to conduct the study yourself. You instead must rely on the experiments of others, on the data collection provided by those scientists who have done the experiments. Sometimes these are wrong, and hence re-testing and the verification of those experiments are necessary by other scientists. Science changes with each re-examination, and often requires multiple labs and institutions on an international scale of research. A single entity cannot dictate the reality of an experimental outcome, but only through re-testing and verification from many sources and unique institutions can you come to a better understanding of the world around you. This requires a global and international pursuit of knowledge, and with the free exchange of ideas.
The future will bring new technological breakthroughs in preserving the natural world, and human dominance of the Earth. Some of these technologies will bring forth new responsibilities, while others might solve the great crises that we face today. Replacing antiqued modes of transportation, air polluting sources of energy, and more sustainable solutions for a more cost effective and less destructive resource utilization of Earth’s materials, both organic and inorganic is needed. The old ways of living on Earth are unsustainable, requiring new ways to drive economic pursuits that safely protect the environment and human health. This will require better governance, and increased participation of science within policy decisions.
