Practise IB Biology SL A4.2.6 by identifying how pesticides, urban growth and agricultural clearance threaten pollinators and biodiversity.
Insect pollinators are vital to maintaining the biodiversity of ecosystems, but they are threatened by some human actions. Some pollinators, such as honey bees (Apis mellifera), produce honey, which is rich in glucose.
List human actions that could threaten populations of insect pollinators such as bees.
a. use of pesticides/insecticides (which may kill/harm pollinators);
b. urbanization;
c. loss of habitat/change of land use (monocultural/intensive farming practices);
d. use of herbicide or removal of "weeds" reducing food sources;
e. introduction of alien species;
For a. or d. the mention of a specific pesticide or herbicide would be ok.
