1. ENVIRONMENTAL CONSERVATION IN Jimmy Chung 6B (9)

2. What does environmental conservation mean? It means • wise management of our environment, • BUT NOT stopping the use of natural resources

3. Four aspects • Protection of natural habitats • Maintenance of the diversity of organisms • Effective use of natural resources • Control of pollution

4. Conservation - Habitat Protection The types of ecosystems in HK • Forests like Tai Po Kau Forest • Freshwater like Stream in North Lantau • Intertidal like Mai Po • Marine • Islands like Lantau and Lamma

5. Marine Advantages: • Hong Kong has 80 hard coral species, at least 59 of them can be found in Hoi Ha Wan, which is comparable to the Caribbean Sea(加勒比海)! • And there are 320 species of reef fishes that can be found in Hong Kong waters.

6. Importance of marine • sources of beauty, • provide habitat for wildlife, • remove pollutants, • provide food control, • maintenance of biodiversity • Entertainment for people • Sources of drinking water

7. Problems • Pollution, over-exploitation, uncontrolled fishing, reclamation due to coastal development have probably played a part in destroying the ecosystem of marine. • The current situation is a serious threat to marine biodiversity in Hong Kong waters. • Some previously common food fishes are now almost extinct here like Zebrafish • One scientific study using advanced modeling has predicted that local waters are not far from ecosystem collapse. We must not let this happen!

8. Solution • Stop water pollution whether industrial or artificial – Victoria Harbor • Water Treatment Plant • impose a “closed fishing season” and “no-take” zones to allow fish stocks to recover and reproduce undisturbed

9. Real case • In 2002, draft map of the proposed Soko Islands Marine Park is prepared because the waters of Soko are important habitats of Chinese white dolphins and Finless porpoises, and important fishery to reproduction and nursery grounds. • However, the designation of the Marine Park has never come to reality although the Country and Marine Park Board endorsed the proposal.

10. On 1st September 06 , China Light Power (CLP) has announced its intention to construct a liquefied natural gas (LNG) terminal on the South Soko Island.

11. Protection of endangered species in HK • Romer’s Tree Frog (Philautusromeri) (盧氏小樹蛙) • Chinese White Dolphin • Four aspects • Black-faced Spoonbill

12. Effective use of natural resources • Nearly all energy consumed in Hong Kong comes from fossil fuels • non-Renewable energy - exhaustible • major sources of air pollutants and carbon dioxide lead to global warming, acid rain etc. • Water is one of the most important resources in the world, we cannot live without water.

13. What can we do? Green Use of electricity • Use alternating current electricity or rechargeable batteries instead of disposable ones. This saves your money as well as the environment by reducing of solid-waste of disposable batteries • Energy saving light bulbs consume less electricity and produce less heat. They save 75% of electricity and are 10 times more durable than ordinary ones.

14. Green Use of water • showering takes only half of water use for bathing, and saves 67% of energy • Collect a load of clothes for washing together

15. Green Travel • Use public transport, such as the railway and buses, whenever possible to save money as well as energy • Switch off the engines while waiting • Turn off the light and air-conditioner when no use

16. Buy Green • Think twice before you buy! Before every purchase, ask yourself "Do I really need it?" • According to a survey, each person in Hong Kong everyday throws 4 plastic bags away. • We should reduce to create the plastic bag, as some of them may be non-biodegradable

18. Control of pollution • Air pollution • Water pollution I hate pollution • Noise pollution • Waste pollution

20. Recycling of waste materials • Recycling bins set up by the Food ad Environmental Hygiene Department • Blue for waste paper • Yellow for aluminium cans • Brown for plastic bottles • Bins for disposal of BBQ forks in country park • Recycling for rechargeable battery • Recycling for the carbon powder box of printer

24. Why do we need to carry out environmental conservation? • we want the way of development meet the present needs while compromising the needs for a good quality of life in our future generation =>To have sustainable development

25. Governments’ effort • Legislation and policies • Latest news - 'polluter pays' principle Environmental levy on plastic shopping bags proposed 0.5 cent per each plastic bag in some large-scaled supermarkets 'polluter pays' principle • Environmental education

26. How can we do something to contribute to environment? • As a resident, we can remember the "6 Rs of Environmental Protection"? • 1st R – Reduce: Buy only what we really need – there is no waste to treat when there is nothing to begin with. • 2nd R – Reuse: If an item is purchased but you do not want to bury it underneath the ground forever, you may resort to this R to make the full use of the item or waste. • 3rd R – Recycle: This should be done for a broken object which cannot be reused. • 4th R – Replace: This is to use environmental goods as much as possible. You may replace a napkin with a handkerchief, or use public transport instead of private cars to reduce the damage to the earth. • 5th R – Rethink: Think twice before an action – think about what kind of impact your action will do to the globe. • 6th R – Redundant: Environmental protection is about actions. Thoughts without actions are “redundant” to the work of environmental protection.
