Effect of global climate change
  1. The need for conservation of biodiversity
    1. allowing biodiversity to decline means genetic divercity will also decline and lose the natural soloution to some of our problems
      1. wild animals and plants may hold the arnswer to problems caused by climate change
        1. They have has thousands of years to evolve and adapted to overcome problems by the environment
          1. we maybe able to breed new crop varites to cope with the conditions
            1. genetic engeerning to produce transgenic species
            2. new medicines found in wild plants
              1. important to maintain genetic diversity in plants due to the potential that exists in the rage that is alive
            3. Importance of genetic diversity
              1. With out, plants and animals would not be able to adapt to changes in the environment
                1. Threats include
                  1. Chanages in the climate
                    1. Increase levels of pollution
                      1. New disesases
                        1. New pests
                        2. humans affect the GD of natural habitats
                          1. reduces the gene pool and decreases genetic variation
                          2. Agriculture
                            1. monoculture
                              1. reduces variation and genetic diversity
                                1. leads to extintion whithin a species
                                  1. genetic erosion
                              2. selective breeding
                            2. Climate change
                              1. species will not be able to adapt to climate change and will have to move
                                1. animals and plant will move towards poles
                                  1. however their are obstructions to migration
                                    1. human developments
                                      1. Agricultural land
                                        1. Large bodies of water
                                          1. Humans
                                      2. agriculture
                                        1. several factors effecting agraculture and biodivercity
                                          1. Higher CO2 levels , altering photosynthersis
                                            1. Higher temps increacing growth rates
                                              1. Longer growing seasons
                                                1. Greater evporation of water ,so grater preceptition
                                                  1. Change in distrabution of preceptition
                                                    1. Loss of land due to rise in sea level
                                                    2. we have developed plants that have a high % yeald and little vairation
                                                      1. they will be unable to evolve and adapt to a changing enviroment
                                                    3. Dieseases
                                                      1. crops being grown in new areas will encounter new dieseases and pests
                                                        1. they have no resistance
                                                          1. higher temps provide a longer growng time but pests will have more time to increase in numbers
                                                            1. in winter pests will be able to cause greater infestations so plants will have a lower % yeald
                                                          2. human dieseases will migrate
                                                            1. tropical dieases will be able to thrive in warmer europe
                                                              1. causes a spread of new dieases
