    1. 30,000 hectares of land in Sudan for agriculture seeing as Abu Dhabi is a desert with limited water
      1. The land was given to them free of charge in exchange for tech experties
      2. good idea?
        1. Yes because it give the country a food supply
          1. They have good connections with Sudan
            1. With food prices increasing and might have shortages they have enough food when it becomes hard to come by
          2. Education
            1. 240 litre bins for food and drink cans
              1. For recycling
                1. Empty each week
              2. Advise on reusing materials

                3. Thomas Malthus
                  1. 1798 he wrote an essay about population
                    1. He said natural checks would decrease the population
                      1. He believed that humans job was to keep the population low
                        1. It would get to a manageable level before rising again
                        2. He believed that population grew exponentially (1,2,4,8,16 ect)
                          1. He believed the population would decrease from starvation
                          2. Ester Boserup

                                  1. So she argued that food production doesn't limit or control the population
                                    1. She claimed that growth controls farming methods
                                  2. She used the term 'agricultural intensification' to explain how how farmers can get more food from the same field increasing their yield
                                  3. Black gold
                                    1. Peak gold
                                      1. When oil production reaches it maximum
                                        1. When it is reached oil prices will increase and become difficult to extract
