Oct 3, 2017 – Second day at sea – enroute from Vancouver, BC to Hilo, Hawai’i
Hawai’i Cruise 2017
At Ginny Stibolt’s talk this morning: Rainforest: The Most Diverse Ecosystems in the World, I learn:
- Photosynthesis and respiration are equal and opposite natural cycles
- Only about 20% of oxygen produced is supplied freely to outside the rainforest, 80% is consumed internally to the rainforest
- Forests only temporarily sequester carbon, unlike oceans where carbon is more-or-less permanently sequestered
- In Borneo, 700 tree species are found in 25 acres
- 80% of insect species are found in tropical forests
- Old cellphones are being used in the Amazon to detect the sounds of chainsaws cutting trees, and transmitting reports back to authorities. They are powered from solar panels.
- Costa Rica is restoring their rain forest by planting at least 15 native species of plants and trees
It is 19ºC at noon today, but when I was outside on Promenade Deck walking four circuits, I was wearing my fleece jacket zipped up because of the cool breeze. I go to the Explorations Cafe at noon for a cappuccino and have a chocolate chip cookie and a couple of little cocktail sandwiches for a lunchtime snack, since I’m skipping having a big lunch today. This afternoon the mv OOCL London container ship sails very close to the Eurodam (see banner image above).
I go to see an hour-long video this afternoon produced by the BBC: Earth Inside Earth: A Privileged View. This is very interesting, highlighting wildlife photographers working in the Empty Quarter of the Arabian Desert in Jordan, with Capuchin monkeys in SE Asia, and with breeding Adela Penguins in Antarctica.
