In this 60 minute overview class, that is informal similar to a club, we will explore the concept of Earth's ecological fragility and the importance of environmental awareness. One important issue we will address is the challenge of perceiving the impact of pollutants on our vast planet. Often, these pollutants are not readily visible, making it difficult to understand their true effects.  

We will study some online Earth models used to study world ecology.  The main model we will use needs no programming (Earth model free on YouTube:  https://earth.nullschool.net), and we will discuss creating simple overlays with transparent pages that one can hold over the online Earth image to get a basic idea, as well as where to get pollution stats/data.  We will also briefly study the more complex Google Earth Engine model https://earthengine.google.com/noncommercial, free Google tutorials are on https://developers.google.com/earth-engine/tutorials/tutorials.  One can add data to this existing model.  These Earth models also have free tutorials on YouTube.

Online Earth Models Can Reveal:
o	Simulation of Ecosystems: By inputting data on flora, fauna, soil composition, water sources, and atmospheric conditions, AI can generate a realistic virtual model that mimics the interactions and dependencies within an ecosystem.
o	Scaling Ratios: Can accurately scale the model to represent a tabletop biosphere that proportionally reflects the dynamics of Earth's larger systems. This includes simulating the right proportions of different species, water bodies, and land areas.
	
Introducing Contaminants:
o	Chemical Pollutants: Can model the introduction and spread of chemical pollutants like pesticides, heavy metals, and plastic particles. It can visualize how these contaminants accumulate in soil and water, move through the food chain, and affect different species over time.
o	Electromagnetic Pollution:  Can simulate the impact of electromagnetic waves from technology and wireless signals. It can demonstrate how these waves might influence plant growth, animal behavior, and other ecological processes.
o	Air and Water Pollutants: The Earth model can include air pollutants like carbon dioxide, sulfur dioxide, and particulate matter, showing their effects on air quality, plant health, and water acidity. It can also simulate water pollutants, illustrating how they alter water chemistry and affect aquatic life.
	
Visualizing Impacts:
o	Time-Lapse Visualization: Can create time-lapse visualizations to show the long-term effects of pollutants. Students can observe how pollutants accumulate and spread, and how ecosystems respond over days, months, and years.
o	Interactive Elements:  Can be interactive, allowing students to introduce different types and amounts of pollutants and observe the outcomes. This approach enhances understanding of cause-and-effect relationships in ecological systems.

Educational Insights:
o	Data Analysis: Can analyze the data generated by the model to provide insights into the most critical factors affecting ecosystem health. It can help students understand concepts like bioaccumulation, trophic levels, and ecological balance.
o	Scenario Exploration: Students can explore various scenarios, such as the introduction of renewable energy sources, the reduction of pollutants, and the implementation of conservation measures. This fosters critical thinking about sustainable practices and environmental stewardship.

As we observe online Earth models, this will lead us to reflect on these diverse perspectives. Consider how increasing our awareness and empathy can lead to more compassionate and effective environmental actions. Reflect on the dangers of indifference and the moral implications of our choices, and appreciate the rich cultural and religious traditions that offer guidance on living in harmony with the Earth.
