Drip tip leaves = channels water off the leaves which prevents water logging
State and explain how an animal has managed to adapt to the rainforest
Poison dart frog = if they eat poisonous insects they absorb the toxins - survive predators
What are the threats to biodiversity
Wildfires
Floods
Disease
Deforestation

What is the value of tropical rainforests

How does ecotourism work to sustainable manage rainforests + any limitations
Economically + environmentally sustainable jobs for people on a local scale
Improves education about the importance of sustainably managing the rainforest
Expensive so not available to all
How does the 2006 International Tropical Timber Agreement work to sustainable manage rainforests + any limitations
Discourages the sale of hardwood timber to prevent illegal logging
Encourages the purchase of sustainably grown timber
Could create an illegal market for hardwood timber
May push illegal logging underground
How does selective logging work to sustainable manage rainforests + any limitations
Only fells fully grown trees so younger trees are preserved
Older trees are less valuable ecologically
Difficult to police and manage due to illegal logging
