BAB 7 : ISU-ISU LINGKUNGAN | Part 1 : Kesehatan Lingkungan & Pemanasan Global | IPA Kelas 9 Kumer

Introduction

This tutorial covers the key concepts of environmental health and global warming as presented in the video "BAB 7: ISU-ISU LINGKUNGAN | Part 1: Kesehatan Lingkungan & Pemanasan Global" by Miss Maya Channel. It aims to provide students with a clear understanding of environmental issues relevant to Indonesia, particularly how they affect health and contribute to global warming.

Step 1: Understanding Environmental Health

• Definition: Environmental health refers to the aspects of human health determined by physical, chemical, and biological factors in the environment.
• Key Components:
  • Air Quality: Poor air quality can lead to respiratory diseases. Monitor air pollution levels in your area.
  • Water Quality: Contaminated water can cause various health issues. Advocate for clean water sources.
  • Waste Management: Improper waste disposal can lead to environmental degradation and health risks. Support local recycling initiatives.

Practical Advice

• Conduct regular assessments of local environmental conditions.
• Engage with community programs aimed at improving air and water quality.

Step 2: Exploring Global Warming

• Definition: Global warming refers to the long-term rise in Earth's average surface temperature due to human activities, particularly the emission of greenhouse gases.
• Causes:
  • Fossil Fuels: Burning coal, oil, and natural gas releases carbon dioxide (CO2).
  • Deforestation: Trees absorb CO2; cutting them down reduces this absorption.
  • Agricultural Practices: Certain farming activities release methane and nitrous oxide, potent greenhouse gases.

Practical Advice

• Reduce personal carbon footprint by using public transport, conserving energy, and supporting renewable energy initiatives.
• Participate in tree-planting activities to combat deforestation.

Step 3: Recognizing the Impact of Global Warming

• Effects on Health:
  • Increased temperatures can lead to heat-related illnesses.
  • Changes in climate patterns can affect food security and lead to malnutrition.
• Impact on Biodiversity: Global warming threatens species extinction and disrupts ecosystems.

Practical Advice

• Stay informed about local climate initiatives and support policies aimed at reducing greenhouse gas emissions.
• Encourage sustainable practices within your community.

Conclusion

Understanding environmental health and global warming is crucial for maintaining a healthy society and planet. By focusing on air and water quality, reducing greenhouse gas emissions, and advocating for sustainable practices, we can make a positive impact. As you continue your studies, consider exploring the next parts of this series, which will cover energy crises and food security challenges. Remember, small actions can lead to significant changes in your community and beyond.
