  1. Tropical Rain Forest - Man-land relationship

  2. 1 What is happening to tropical rainforests?

  3. Rainforest in Temburong, Brunei Luxuriant growth of plants? (Credit: Ng Kim Hung) What are your impressions about a tropical rainforest?

  4. Rich diversity of plant and animal species?

  5. (Credit: Reuters/OTHK) Or the deforested scenes of rainforests? Where are the tropical rainforests? Destroyed Amazon rainforest

  6. Tropical rainforests can be found between the Tropic of Cancer and the Tropic of Capricorn. Tropical rainforests are found mainly around the Equator and the area between latitudes 10o N and S. These regions usually have high temperature, rainfall and humidity. Where are tropical rainforests? Where can we find the largest area of tropical rainforests in the world? Where can we find tropical rainforests?

  7. Tropical rainforests can be found between the Tropic of Cancer and the Tropic of Capricorn. The largest area of tropical rainforests in the world is in the Amazon Basin in South America. Where are tropical rainforests? Congo Basin South-east Asia Amazon Basin Where can we find the largest area of tropical rainforests in the world? Where can we find tropical rainforests?

  8. What has happened to tropical rainforests? What has happened to the tropical rainforests in the Brazilian Amazon? The change in the Brazilian Amazon rainforest cover (1990–2006) The rainforests in the Brazilian Amazon has been losing at a rapid rate.

  9. Deforestation carried out along roads, developing ‘fish-skeleton’ patterns How can we identify the phenomenon from satellite images? Undisturbed forest 1986 1992 1975 (Credit: NASA) Satellite image of Brazilian Amazon in 1975 Satellite image of Brazilian Amazon in 1986 Satellite image of Brazilian Amazon in 1992

  10. How can we identify the phenomenon from satellite images? What changes had been taken place in the rainforest cover? The rainforest cover in the Brazilian Amazon had been shrinking between 1975 and 1992. 1992 (Credit: NASA) Roads were built into the rainforest, where forests were cleared along them.

  11. How about the situation in other rainforests in other parts of the world? South-east Asia: most seriously deforested Congo Basin: relatively slower rate, but still significant Amazon Basin: deforested in an alarming rate Source: Washington DC: Global Forest Watch Changes in tropical rainforest cover throughout the world

  12. What has happened to tropical rainforests? Are tropical rainforests disappearing rapidly?

  13. What has happened to tropical rainforests? 423290 8.14 56.10 69210 4.92 56.98 Do you know? 280720 24.08 46.46 14140 2.02 53.49 7110 1.16 53.32 40550 6.46 53.47 20860 6.62 63.60 8540 6.24 14.98 47780 6.92 32.80 2550 1.12 65.70 The Amazon Basin holds about 1/3 of the worlds’ rainforests. Another 20% are located in Indonesia and the Congo Basin.

  14. What has happened to tropical rainforests? Each second: About 1 hectare of rainforest disappears (= the area of 1 Hong Kong Stadium) Each minute: About 60 hectares of rainforest disappears (= the area of 60 Hong Kong Stadium) Each day: About 86 000 hectare of rainforest disappears (about 0.8 times of Hong Kong’s total area) Each year: About 31 million hectare of rainforest disappears (about 282 times of Hong Kong’s total area)

  15. What has happened to tropical rainforests? More than 2/3 of the world’s tropical rainforests are damaged by human activities. Deforestation refers to human extraction of resources by cutting trees down. The scale? Tropical rainforests once covered about 12% of the Earth’s land surface but now they are reduced to 5% today.

  16. Why do people remove the rainforests? How should rainforest resources be managed and conserved? What can we do to help protect and sustain tropical rainforests?
