Balancing Pests and Pesticides: Understanding the Impact on Ecosystems

Explore the delicate balance between pests and pesticides in artificial ecosystems, their effects on natural environments, and the implications of pesticide use. Learn about the harms caused by pollutants, risks to non-target organisms, and the challenges of bioaccumulation, bioamplification, and resistance development. Discover why pests are only a concern in artificial ecosystems, highlighting the importance of maintaining a natural balance for a sustainable environment.

  1. Pests & Pesticides Pest: any plant, animal, or other living organism that causes illness or harm and is an annoyance to humans

  2. Pests & Pesticides Pest: any plant, animal, or other living organism that causes illness or harm and is an annoyance to humans e.g. weeds –compete with crops

  3. Pests & Pesticides Pest: any plant, animal, or other living organism that causes illness or harm and is an annoyance to humans e.g. weeds –compete with crops insects –eat crops

  4. Pests & Pesticides Pest: any plant, animal, or other living organism that causes illness or harm and is an annoyance to humans e.g. weeds –compete with crops insects –eat crops parasites –eat humans

  5. Pests & Pesticides There are no "pests" in natural ecosystems. -only producers, consumers, and decomposers.

  6. Pests & Pesticides There are no "pests" in natural ecosystems. -only producers, consumers, and decomposers. -natural ecosystems are in balance

  7. Pests & Pesticides There are no "pests" in natural ecosystems. -only producers, consumers, and decomposers. -natural ecosystems are in balance Pests are only "pests" in artificial ecosystems because these ecosystems are not in balance. -we have to control the pests

  8. Pests & Pesticides Pesticide: a substance used to kill pests

  9. Pests & Pesticides Pesticide: a substance used to kill pests Problems with Pesticides: 1. Pollution: sprayed pesticide that gets carried away and affects surrounding air, soil, or water

  10. Pests & Pesticides Pesticide: a substance used to kill pests Problems with Pesticides: 1. Pollution: sprayed pesticide that gets carried away and affects surrounding air, soil, or water 2. Non-target Organisms: other insects, such as honeybees, can be killed

  11. Pests & Pesticides Pesticide: a substance used to kill pests Problems with Pesticides: 1. Pollution: sprayed pesticide that gets carried away and affects surrounding air, soil, or water 2. Non-target Organisms: other insects, such as honeybees, can be killed 3. Bioaccumulation: the build up of a pesticide in the body of an organism -pesticides can become toxic to humans if allowed to build up in our bodies

  12. Pests & Pesticides 4. Bioamplification: the increase in concentration of a pesticide as it moves higher up the food chain

  13. Pests & Pesticides 4. Bioamplification: the increase in concentration of a pesticide as it moves higher up the food chain 5. Resistance: insects can develop resistance to a pesticide and it requires more to do its job or becomes useless
