The importance of:
BIODIVERSITY
FOREST
WATER
Students’ presentation
Plants absorb greenhouse gases and help stop global warming.
It is easier for biodiverse ecosystems to recover from natural disasters.
Healthy biodiversity of species can provide a variety of food (like meat and products). 
Many of our medicinal drugs come from plants.
All of our wood products come from nature.
Many recreational areas benefit from a healthy ecosystem, which promotes tourism.
Biodiversity is beautiful and should be enjoyed.
These values are free to us, but as we lose biodiversity the cost of replacing these (if even possible) would be very high!
What we can get from nature
The threat to:
BIODIVERSITY
FOREST
WATER

Using up natural resources before they can be renewed (over-fishing in oceans, or over-harvesting trees on land)
Habitat destruction like clearing forests or draining wetlands for towns or agricultural purposes
Releasing invasive species into foreign ecosystems (like the cane toad in Australia or the zebra mussel in the Great Lakes or yellow snails in our country )
Any kind of pollution (water, air, soil, etc).
Failure of food chains
