Trend = Pattern
follow the trend
BREAKS AREN'T NECESSARILY EQUAL!
(Based on Patterns)
The 8 Biomes are:

WORDS TO KNOW
Names, Lines of Latitude and life
Tropical Rainforest, Tropical savannah,Desert, Chaparral, Grassland, Temperate deciduous forest, Temperate Boreal forest & Tundra

Cutting down forests to gain extra land.
pillars of food security
- The latitude belt between 10 degrees and 30 degrees N and or S
- Grasslands with a few scattered trees
- Experience a wet and dry season
- Hot temperatures
- Annual rainfall is between 50 and 127 cm
More species of grazing mammals than any other biome
Utilisation (Pillar 3)
- Food security involves the cleanliness and utilisation of the food.
Ivory Coast in Africa is a popular supplier of Cacao Beans, those brown things that make up your chocolate. What people don't know is that Cocoa suppliers are trafficking children across borders to work to harvest the beans. Not only is this an illegal act, but it is also disgustingly unethical and inhumane.
Access (Pillar 1)
Food security involves the physical and economical access to enough food for an active and healthy life.
Availability (Pillar 2)
– Food security involves the availability of good quality, nutritious food from local, regional, and international sources.
Cacao beans go through a long process to become a chocolate bar.
- It is a nutritional imbalance commonly linked to a lack of nutrients required to maintain a healthy life. Malnutrition can involve undernourishment. (Lack of Food)
Farming that provides for the basic needs of the farmer without surpluses for marketing.
- Typically found between 25 degrees and 40 degrees latitude
- Receives less than 25 cm of rain each year
- Temperatures typically range between 20 degrees Celsius and 25 degrees Celsius but some extreme deserts can reach temperatures higher than 38 degrees Celsius and lower than –15 degrees Celsius
- Meaning that you are lacking the necessary nutrients for a healthy diet.
provide with the food or other substances necessary for growth, health, and good condition.
Less developed country
A country which isn’t very civilised socially wise, cleanliness wise, education wise and food wise.
First, the pods need to be harvested from the the cacao trees. These are hand picked, the mature ones being identified and hacked off from the trees. The pod is then broken open and the beans are extracted from the pods. After this, the beans need to be fermented, and are wrapped in banana leaves or placed in containers. The fermenting process should take around 8 days. The beans are now dried until there is only 6-7% moisture in the beans.
When dried, the beans get packaged and shipped off to manufacturing factories.
A developed country or "more developed country", is a sovereign state that has a highly developed economy and advanced technological infrastructure relative to other less developed nations.
the state of being inferior in quality or insufficient in amount.
zero population growth rate
the maintenance of a population at a constant level by limiting the number of live births to that needed to replace the existing population.
- Population density is a measurement of population per unit area or unit volume.
Food security refers to the availability of food and one's access to it. A household is considered food-secure when its occupants do not live in hunger or fear of starvation.
genetically modified foods
food produced from organisms that have had specific changes introduced into their DNA using the methods of genetic engineering
the ability to be sustained, supported, upheld, or confirmed
- Found between 32 degrees and 40 degrees latitude on the west coast of continents
- Receives between 35 and 70 cm of rain, usually in the winter
- Extremely resistant to drought and weather events
1940s - 1960s, increase in agriculture production worldwide, particularly in the developing countries, saving people from starvation, high-yielding varieties of cereal grains, modernization of management techniques, distribution of hybridized seeds etc.
Doesn't follow the pattern
Use statistic + examples
At the manufacturer, the beans are first cracked, a the hard shells of the beans contain 53% cocoa butter. Then, the beans are ground into a chocolate liquor. The liquor is then refined once more, to either make the particles smaller or to distribute cocoa butter evenly throughout. Other substances are added to give the chocolate flavour and texture, such as sugar, milk and vanilla. The liquor is then placed into the conch machine, which kneads it continuously, increasing the value of texture and flavour. After the 5-day conch machine process, the chocolate is tempered and molded to be distributed. It's also packaged... DUH.
- 37°21′N to 34°51′15'S latitude
- Because of the dry climate, trees are found only near water
sources such as streams
- Usually receives between 50 and 90 cm of rainfall each year
Summer temperatures can reach up to 38 degrees Celsius, and winter
temperatures can fall to –40 degrees Celsius
• Hunger: the uneasy or painful sensation caused by want of food; craving appetite. Also the exhausted condition caused by want of food; the want or scarcity of food in a country or a strong desire or craving
• World Hunger: The want or scarcity of food in THE WORLD
- Typically found near the equator found near the equator (0° to 10°)
- Receives more than 200 cm of rain annually
- Temperatures typically fall between 20 degrees Celsius and 25 degrees Celsius for the entire year
As many as 50% of all the world’s animal species may be found here
Temperate Deciduous Forest
How much does a Cocoa bean cost?
How many Cocoa beans are in a bar?
Water management on farm
Stockpiling of food
Availability of food aid
80-85 beans for an average 100g bar.
So, why does a chocolate bar cost so much?
- 23° North to 38° South latitude
- Moderate climate
- Most trees will lose their leaves in the winter
- Temperatures range between –30 degrees Celsius and 30 degrees Celsius
- Averages from 75 to 150 cm of precipitation
- Well developed understory
- Extra ingredients added
- Distribution/ Shipping
Temperate Boreal Forest
- Also known as Taiga
- Typically found between 45 degrees and 60 degrees North latitude
- Cold climate with summer rains
- Very few reptiles
- Limited understory
- Snow is primary form of precipitation( rains ,snows, hail -liquid from the sky)(40 – 100 cm annually)
- Means treeless or marshy plain
- It is 60° to 70° latitude North
- Characterized by permafrost - permanently frozen soil starting as high as a few centimeters low the surface - which severely limits plant growth
- Winter temperatures average - 34 degrees Celsius while summer temperatures usually average below 10 degree Celsius
- Low precipitation ( 15- 25 cm per year ) but ground is usually wet because of low evaporation.
