  When you examine the concept map above, everything ties back to the overarching idea of natural resources and their utilization. Some resources, such as wind, trees, water, and fish, are considered renewable because nature can replenish them relatively quickly. Others, such as coal, oil, and natural gas, are nonrenewable, meaning that once they are used up, they’re essentially depleted, as they take millions of years to form. Fossil fuels play a significant role in this, as they provide the energy to power cars, heat homes, and run industries; however, they also create problems such as pollution and resource depletion. That’s where the other strands,  sustainability, recycling, reusing, and unsustainable situations,  come in. Sustainability is all about using resources wisely, such as choosing solar energy over fossil fuels or practicing sustainable fishing to prevent fish populations from collapsing. Recycling and reusing are ways to extend the life of materials we al...

 Oceania-More Developed -Birth Rate: 15 per 1000 population -Death Rate: 7 per 1000 population -Population Growth Rate: 2.2% per year -Life expectancy for males and females: 78 years overall (Men: 76, Women: 81) -Fertility Rate: 2.0 -Gross National Income (GNI)- $47812  Oceania is home to roughly 46 million people in mid-2024, and the population is expected to grow to 53 million by 2035 and 61 million by 2050 . Population growth comes from both natural increase, more births than deaths, and migration. The rate of natural increase is about 0.8% per year , with around 15 births and 7 deaths per 1,000 people . Migration plays a significant role, particularly in Australia and New Zealand, contributing to an overall growth rate of roughly 2.2% per year . The region shows a clear divide between the more developed countries and the smaller Pacific islands. Australia and New Zealand have older populations , low fertility (about 1.5–1.6 children per woman), and high life expect...

Chapter 4- Energy and Ecosystems       This concept map shows how energy flows through ecosystems, starting with sunlight and moving through producers, consumers, and decomposers. It also highlights how energy is transferred between trophic levels and why productivity differs between ecosystems. Chapter 7- Biodiversity      This concept map explains biodiversity at three levels: genetic, species, and ecosystem. It shows why biodiversity matters for both nature and people, the threats it faces today, and the main strategies used to conserve it. Chapter 8- Biomes and Ecozones      This concept map illustrates Earth’s major biomes and Canada’s ecozones. It shows how climate and geography shape these regions, and how plants and animals adapt to survive in their specific environments. The three concept maps I created—Energy and Ecosystems, Biodiversity, and Biomes and Ecozones—are interconnected, much like pieces of a puzzle. Energy flow (Chapter ...

Original Photo 1929  Second Photo 2013 Google Earth Viewing August 2022 Palisade Glacier, California 1929-2022 If you look at old photos of glaciers, like the Palisade Glacier in the Sierra Nevada taken back in 1929, and then compare them with rephotographs from 2013, the difference is enormous. The glacier that once stretched far down the mountain has pulled way back, looking thinner, smaller, and more broken up. This change isn’t just about one glacier in California—it’s part of a bigger global pattern we’re seeing everywhere. Glaciers are shrinking rapidly, primarily due to climate change. Glaciers depend on a balance between snowfall in the winter and melting in the summer. For thousands of years, they held steady because snow would build them back up as fast as the warmer months melted them down. But now, with warmer global temperatures, summers are hotter, and winters often don’t bring enough snow to replace what’s lost. Year after year, this imbalance adds up, and the result...

I live in a utilities-paid apartment, so I don't have a water bill to use. The only person I could have used for this activity was unable to access their water bill information because the website was down, so they couldn't provide the information I needed. Sorry in advance! 

 1. Point of View       The video is told from an environmental history, using the 1969 Cuyahoga River fire as a turning point for both Cleveland and the nation. Its perspective centers on the voices of the community and environmental advocates who pushed for change, rather than on industry or corporate interests. The orientation is hopeful and celebratory, showing the river’s comeback as proof that activism and regulation can lead to real environmental progress.  2. Purpose      The video’s primary goal is to show how the Cuyahoga River went from being super polluted and even catching on fire to becoming a symbol of recovery. It aims to show people how that moment in 1969 sparked significant changes, including the enactment of new laws and increased environmental action. The purpose is really to celebrate that progress and remind us that when communities come together, real change can happen. 3. Questions at Issue      The vid...
