  • No matter how big a country is, if its environment cannot support its human population, it is considered overpopulated.

      in class we talked about how the people had to relocate because of the Three Gorges Dam-this is example of how its envornment cannot support its human population
  • "The richest 20 percent of humanity consume 86 percent of all goods and services, while the poorest fifth consume just 1.3 percent."

      in class we discussed survival of the fittest-here, the richest countries consume the most goods and services and the poorest can't provide enough food, causing world hunger

      This talks about the effects that salinity in the soils have on the production of food crops.
  • salinity exacerbate existing food insecurity and vulnerability problems, and are serious threats to the production of major world food crops such as wheat, rice and maize
  • soil scientists, plant nutritionists and plant breeding and genetic scientists work together to bring about solutions and hope to farmers in areas that are vulnerable to soil fertility and environmental stresses

  • Salt, drought and nutrient resilience crops are being developed by plant breeders
  • grown in the field using good soil nutrient and water management packages that are tailor-made to local growing conditions

      This is talking about how they are trying to make sure that they can reduce the salinity in soils to make sure that the food products are okay to consume.
  • problems, and are serious threats to the production of major world food crops such as wheat, rice and maize. It is estimated that over 77M ha of land is devastated by drought, salinity and nutrient deficiencies that are brought about by long-term nutrient mining and climate change and variability.

      we did a lab over how too much soil salinity can disrupt the germination of crop seeds and therefore reduce production of food. this might one day lead to world hunger
  • bility. Using these technologies, soil scientists, plant nutritionists and plant breeding and genetic scientists work together to bring about solutions and hope to farmers in areas that are vulnerable to soil fertility and environmental stresses.
