factors affecting biodiversity

Question 1

global warming effect on biodiversity

Answer 1

melting polar ice caps
rising sea levels
higher temps and rainfalls
insects

Question 2

the importance of slowing climate change

Answer 2

species may have time to adapt
they could find a different food source/migrate
lead to loss of native species, others could move into the area, biodiversity would not necessarily be lost
mix could simply change

Question 3

how is agriculture responsible for loss of biodiversity

Answer 3

deforestation, increase land for planting of crops/rearing animals
removal of hedgerows, allow farmers to use large machinery to plant, fertilise and harvest, free up additional land
use of pesticides, pests destroyed are a food source for other organisms

Question 4

how can deforestation affect biodiversity

Answer 4

reducing the number of trees
if a specific type of tree is felled, species diversity is reduced
reduce number of animal species in the habitat
animals forced to migrate to survive which affects neighbouring area
