- Amazon Rainforest
- general info
- hot and wet climate all year round
- soil isn't very fertile and rain washes nutrients away
- most trees are very tall evergreens
- more animal species than any other ecosystem
- home to many people
- rainforests are interdependent ecosystems
- one thing changes everything will change
- plant adaptations
- tall trees have big buttress roots to support trunks
- thick waxy leaves with pointed tips so water runs off
- smooth thin bark water run off easiy
- four distinct layers of trees
- lianas use tree trunks to climb to sunlight
- drop leaves through year so can always grow
- animal adaptions
- strong limbs to climb trees
- flaps of skin to glide to trees
- camouflaged to hide from predators
- many animals are nocturnal so hunt when cooler
- many animals can swim to cross river crossings
- biodiversity is variety of organisms living in a place
- 50% of plants animals and insect species
- don't have to cope with changing climate
- 50% of plants animals and insect species
- deforestation
- why
- population pressure
- mineral extraction
- energy development
- commercial logging
- commercial & subsistence farming
- environmental impact
- soil erosion leading to landslides and floods
- no tree canopy= too much water nutrients washed away
- deforestation =15% of CO2 emissions
- economic impacts
- creates jobs
- lot of money is made
- money lost from tourism
- livelihood of locals is destroyed
- why
- rate of deforestation is changing
- globally rate is slowing down
- still hotspots - borneo and Nigeria
- brazil and Indonesia accounted for almost half of global deforestation
- brazil is reducing rate
