- Global Population Futures
- Agricultural Productivity
- Direct Impacts
- Mid to high latitudes crop yield increase
- Southern crops viable in northern areas
- 64% increase in Russia's farming
- Crop decrease in the south
- Indirect Impacts
- Widespread pest dispersion e.g. aphids
- Changes in irrigation availability
- Flooding drowns crops
- Direct Impacts
- Nutritional Standards
- Developed Regions
- Different pesticides
- Obesity culture
- More regimes pertaining to healthy eating
- Changes to food safety
- Developing Regions
- More meat consumption
- More livestock = more CH4
- Less cereal based diets
- Undeveloped Regions
- Unpredictable rainfall = less chance of growing crops
- Livestock sold in times of hardship
- Leads to iron deficiencies
- Malnutrition
- Developed Regions
- CHANGES IN VECTOR ECOLOGY
- Malaria and Dengue
- Extra 2 billion exposed to Dengue by 2080s
- Warmer climate will worsen distribution
- Lyme Disease
- Borellia bacteria
- Temperate climates
- Zika Virus
- Aedes mosquito
- Outbreak in 2014, Easter Island
- Women conceive babies with micro-cephaly
- West Nile Virus
- 1999-2010 outbreak in North America
- Exists outside normal climate
- Transmission factors
- Vector survival
- Reproduction and biting rates
- Climate and altitude
- Malaria and Dengue
- OZONE DEPLETION
- Skin Cancer
- UV damages skin cells
- Australia
- 2000 skin cancer deaths / year
- 2/3 will have skin cancer by age of 70
- Highest in S. of England
- Long-term sun exposure
- Cataracts
- UV damages parts of the eye e.g. lens
- Treatment
- Good sunglasses
- Surgery
- 10% ozone depletion = 2 milllion new cataract cases / year
- Halogenated chemicals e.g. CFCs
- Cause ozone molecules to decay
- More UV radiation reachs earth
- Worsening factors
- Locations nearer the equator
- Time of day
- Altitude
- Wide, open, reflective spaces
- Skin Cancer
- Agricultural Productivity
