Global biodiversity is the variety
and abundance of life on Earth
The life on Earth provides a range of
ecological life-support services as
well as resources that we exploit
Sustainable development
and conservation are
required to maintain
access to there resources
Resources
Wood
Used in the manufacture of
buildings, tools and furniture
Fibres
Cotton, wool, paper, silk,rayon
Oils
Vegetable and animal
oils are used in foods,
lubricants and soaps
Fuels
Wood, charcoal, alcohol, vegetable oils
Food
Plants, animals, algae and fungi
New Food Species
Few of the known plant/animal
species are used for food.
Some of these animals/plants are kept in habitats they
are not adapted to, this reduces productivity
Indigenous species are usually better
adapted than introduced species, to local
conditions, giving them higher survival rates
Example of conditions include:
Climate, pests and soil conditions
Selective breeding may be needed
to enhance desirable features
Plants species that have
potential for commercial
cultivation
Potato Bean of North America
High protein content
Morama Bean from dry
areas of southern Africa
Protein content
similar to soya and is
drought resistant
Yeheb Tree from Somalia
Produces edible nuts, is drought
resistant and can grow in poor soils
Spinach
Many species of spinach can grow
in soils with high salt content.
Could be used in breeding programs to increase
the salt tolerance of other crops in areas where
irrigation has caused soil salinisation
Perennial variety of
Maize from Mexico
Perennial means it grows
year on year, so you do not
need to buy new seeds
Also reduces the need to plough
which reduces the risk of soil erosion
Kernza
Perennial, so has similar
advantages to perennial maize
Animal species
investigated for
domestic farming
E.g. American Bison, Common
Eland, Common Ostrich, Cane
Rats, Emu and Giant Land Snails
Biomimetics
The use of knowledge of
adaptations of other species,
to improve the design of
manufactured goods
Transport Design
Splayed wingtip feathers of birds
help reduce turbulence and drag.
Aircraft's copy this to
improve fuel efficiency
Humpback whale flippers have tubercles (bumps)
to channel water flow, increasing hydrodynamic
efficiency allowing them to turn tighter
Now been applied to ship rudders
and aerogenerator blades
Ships can now turn tighter, and aerogenerators
need a lower wind speed to spin
Infection Control
Bacteria doesn't stick easily to shark skin
A coating that imitates shark skin is used in hospital
operating theatres to help control bacterial infection
Architecture
The mounds that termites construct above ground,
become hot and causes the hot air inside to rise. This
draws out stale air at lower parts and creates a
solar-driven ventilation system
This system has been adopted by shopping centres
and office blocks to eliminate the need for air
conditioning units
Adhesion
The toes of gecko lizards have
pads that provide strong adhesion
Attempts are being made to replicate
this to eliminate the need for glue
Some seeds have burs with hooks to stick
to fur of animals, this aids seed dispersal
Velcro copy's this tactic
Lotus flowers have water repelling features
This has been copied in self-cleaning glass
Materials
Some natural materials have properties that can be
applied to the manufacture of synthetic materials
The lightweight, strong, flexible silk produced by
spiders in use to create airbags and body armour
Medicines
Plants produce toxins to protect themselves
from predators, these toxins in carful
amounts can be used as medicines for humas
Poppies
Cultivate to produce painkillers
like morphine and codeine
Willow Trees
Bark was originally used to create Asprin. Now created synthetically
Yew Tree
Taxol is extracted and used to treat a
range of cancers (Breast, ovarian, lung,
bladder and prostate)
Caribbean Tropical
Marine Sponge
The drug AZT was discovered in it. Used to treat HIV/AIDS
Shark Blood
Drug AD 114 is being tested as a
cure for fibrosis of the lungs, based
on antibody in shark blood
Physiological Research
Marsupials give birth at a very
early stage, their young are then
left to develop in mothers pouch
Easier to study marsupials young than a
human of the same age in mothers womb
Hippopotamus skin secretes
hipposudoric acid which is a natural
sunscreen and antimicrobial agent
Being researched to help improve the
treatment of burns victims
Pest Control Species
A wide range of predators, herbivores,
parasites and pathogens are used to
control argricultural pests
