Why Tropical Forest lost over the last 50 years?
- -Subsistence agriculture—to feed oneself (using slash and burn techniques), commercial plantations, cattle ranching, forest fires (with new fire cycles),
- -the forests are often destroyed for fuelwood—made into charcoal (esp tropical dry forests),
- -forests are also destroyed for timber
- -traditional agricultural methods, which are dependent on labor and a large amount of land to produce enough food to feed oneself and one’s family;
- -some methds include: shifting cultivation, slash-and-burn techniques
- -use modern agricultural methods, which require a large capital input and less land and labor than traditional methods;
- -have high yields.
- -Rubber, oil palm, coffee, bannanas, soy bean, coco
Forest Fires in the Tropics
- -New fire cycles.
- -First evidence humans are having effect on climate
- -Forests become more and more degraded and flammable. -El nino causes the forest fires
- -tropical dry forests are rapidly being destroyed for fuel wood.
- -Often the wood is used to make charcoal which is extremely wasteful.
- -planting diff trees together.
- -Makes a border around a town.
- -in the tropics, this wood is hard and colorful (it has no rings in the trunk since their environment doesn’t change seasons much).
- -In tropics no seasons, so no rings
- -no plantations
-forest fragmentation is the break up of large areas of habitat into small, isolated patches, which is a major threat to the long-term survival of many animal and plant species—threat to biological diversity
- depends on:
- -size of animal (our mega fauna are gone), solid forest (very dark), anything rare (density)
- -foreign species that spreads in a new area that it did not evolve in
- -often upsets the balance among organism living in that area and intereferes with the ecosystems normal functioning
- —the foreign species may compete with native species for food or habitat or may prey on them
- -Are relatively small areas of land that contain an exceptional number of endemic species and are at high risk from human activities.
- -They cover 1.4% of the Earth’s area and they house ½ of the worlds species.
- -These hotspots have exceptionally high diversity, endemism, but are at high threat of human exploitation. P. 360.

Less than 33%
Sustainable Development considers three important factors because:
- 1. Environmentally sound decisions-to not harm the environment or deplete natural resources
- 2. Economically viable decisions-consider all costs; including long term costs
- 3. Socially equitable decisions- reflect needs of society to ensure costs and benefits are shared by all groups.
Define sustainable agriculture and some good examples of it
- -This happens when modern agricultural techniques are combined with traditional farming methods.
- -Leaves for future generaltions and doesn’t strain. Only enough for family. It relies on beneficial biological processes and environmentally friendly chemicals that disintegrate quickly.
- -This includes breeding of disease resistant crops to promote animal health, biological diversity to minimize pest problems and water and energy conservation. -
- -Adding animal manure to soil and crop rotation are also good examples of this.
The IPAT equation refers to
- Environmental Impact (I) = The number of people (P) x The affluence per person which is a measure of the consumption or amount of resources used per person (A) x The environmental effects; resources needed and wastes produced of technologies used to obtain and consume the resources (T)I= PxAxT
- -This equation estimates the human impacts on the environment. Shows the mathemical impacts and the forces
- -Impact = People * Affluence * Technology

USE: Acorns were the primary food source for a number of California Indians. Acorns were collected, leached with water in stream and basket to remove tannins (Wine) then heated with rocks for mush. Wood also used for bow
USE: Indians brewed flowers for fevers, upset stomach, flu. One of the richest sources of vitamin C! Stems used for arrow shaft and flutes. Raw berry can cause nausea, but dried or cooked are OK.
USE: Indians would use the leave as mosquito repellent. Lemonade Berry (Rhus intergrifolia) has berries that are soaked and hairs removed to make pink lemonade.
