Chapter 10 / 10 short lessons
Climate change, food and disease vectors
Follow the causes of warming through ecosystems, food production and mosquito biology, then evaluate practical responses and their limits.
H1 Biology / 8876 / 2027 syllabus
What do you think?
A warmer region becomes suitable for a mosquito species. Does that guarantee an outbreak of the disease it can carry?
Lessons
0 of 10 marked as readConnect human activities to warming
Explain the contribution of fossil fuels, deforestation and meat production to CO2 and methane accumulation over recent centuries.
About 5 minTrace ice, water and warming feedbacks
Explain sea-level rise, changing extremes, fresh-water stress and greenhouse-gas release from thawed organic matter.
About 6 minExplain changing ranges and coastal stress
Explain fish and insect range shifts and climate stress on coral reefs, seagrass and mangroves.
About 6 minCoral reefs: a partnership under stress
Explain the coral and zooxanthellae mutualism, the calcium carbonate skeleton, and how warming, ocean acidification and heavy rainfall stress coral reefs.
About 6 minExplain what mangroves can protect
Explain how mangroves reduce climate impacts through carbon storage and coastal ecosystem functions.
About 5 minCompare energy sources over their whole life
Compare fossil fuels, solar power, nuclear power and bioethanol using a consistent life-cycle boundary.
About 6 minCompare food and land-use footprints
Explain relative footprints of meat, plant foods and deforestation using appropriate comparison units and boundaries.
About 5 minTrace climate stress to food supply
Discuss how heat and extreme weather affect plants, animals and sustainable food production.
About 6 minConnect temperature to the mosquito life cycle
Explain insect metabolism, temperature tolerance and temperature-dependent Aedes aegypti development.
About 6 minExplain how disease risk can move beyond the tropics
Explain how warming can change malaria and dengue transmission ranges while recognising other required conditions.
About 6 minWhat you will be able to do
- Connect CO2 and methane emissions to physical and biological effects.
- Compare footprints and explain mangrove protection and food-supply pressures.
- Explain temperature effects on mosquitoes and the conditions needed for disease spread.
