Statement of Inquiry: Lack of human management and intervention may fragilize ecosystems. Global Context: Globalization and sustainability Key Concept: Systems Related Concepts: Management and intervention Factual What is an ecosystem? What human activities have an impact on the natural environment? Conceptual How can humans co-exist with the natural environment? How does tourism have positive and negative impacts on the natural environment? Debatable Are natural systems the responsibility of humans to manage for us, them, or both?
Issues facing our environment
Objectives for our upcoming lessons
To identify different issues caused by human actions facing our environment To understand the impacts such issues have on our ecosystem To evaluate solutions to overcome such issues
As the population grows, our desire for more consumer goods grows and therefore our footprint also grows. The United Nations (UN) estimates that by 2030 we will need two planet Earths to support us.” What does this quote mean to you? How is it relevant to what we are studying?
How much do you currently know about what issues our earth is facing? Why are we said to need “2 planets”? Draw what you understand.
In what ways do we impact the environment?
Our ecological footprint is a measure of the impact each of us has on the environment. It includes the amount of land needed each year to provide food, water, energy and services per person. The more energy we consume, the more travelling we do, and the more natural sites we visit, the larger our ecological footprint. The diagram shows the five components of our ecological footprint:
In a few words, what is land reclamation?
Land reclamation is an ancient technique used by many civilizations, including the Egyptians, to create new land along riverbanks. In modern times, land reclamation is used to create more land for housing, industry, or recreation. In some cases, land reclamation can be used to help protect coastlines from erosion and sea level rise.
Did you know?
What do the following places in Hong Kong have in common?
Land reclamation is the process of taking land from water, or making land from water. It is often done to create more land for development or to create land for agricultural use. The debate of land reclamation focuses on the pros and cons of the process. Those for land reclamation argue that it can help create jobs and provide living space, while those against argue that it damages the environment. The debate over land reclamation is complex and far-reaching, with impacts on the environment, economy, and politics. It is important to understand all sides of the debate before making a decision.
Land Reclamation: A Debated Topic
Land Reclamation: The process of restoring land that has been damaged or altered due to human activities such as mining, deforestation, and pollution. Environmental Impact: The effect that human activities have on the environment, including land, air, and water. Habitat Loss: The destruction or degradation of habitats, which can cause a decline in species diversity and abundance.
Reasons for Land Reclamation
Coastal economic zones: Developing countries to build luxury residential, upscale commercial and industrial spaces. Infrastructure: Building infrastructure such as roads, bridges, ports etc. Agriculture Artificial islands: In cities such as Dubai, artificial islands have been created through land reclamation. Restoring original beaches: Beaches suffering due to coastal erosion can be repaired through land reclamation practices....
Lantau Tomorrow: What is it?
One of Hong Kong’s largest land reclamation projects - artificial islands with a total area of approximately 1,700 hectares! (13 times the size of Hong Kong Disneyland) Accommodate about 260,000 to 400,000 housing units Expansion of road and rail transportation networks to reach the islands Development of the Leisure and Entertainment sectors for a year-round vacation destination with international and local mega competitions/sports events Create in addition to Central and Kowloon East the third Core Business District Provide a suitable network of walking trails to offer diversified sustainable leisure and recreation experience Creation of 480,000 jobs
Do you think land reclamation should be encouraged?
- Yes, it can help boost the economy
- No, it can hurt the environment
- I'm not sure
What are the pros and cons of land reclamation?
Reflecting on our SOI & Key concept
Will too much human intervention further fragilize environments? Which system is more important? Marine ecosystem or Human population?
What would you do if you were Hong Kong’s Chief Executive?
As the main issue faced in Hong Kong is the lack of land supply, will YOU, as Hong Kong’s Chief Executive be willing to spend HK$580 billion on the Lantau Tomorrow project? Make a decision about moving forward with Lantau Tomorrow, or an alternate solution. Draw how your vision would look like (or use AI to create it!) Write a short paragraph to persuade the Hong Kong population why your proposal should be accepted. Consider the impacts on costs, environment and the society.
