Section B: Short Answer Questions

5. Answer will vary.
   Example Response: Industrialization has led to increased air pollution from factories and vehicles, contributing to health problems and climate change. It also results in habitat destruction as natural land is converted into industrial sites.

6. Answer will vary.
   Example Response: The carbon footprint measures the total amount of greenhouse gases emitted by an individual or organization, usually expressed in equivalent tons of CO2. Reducing it is crucial to mitigate climate change and its associated impacts on the planet.

7. Answer will vary.
   Example Response:

   • The Passenger Pigeon became extinct in the early 20th century due to overhunting and habitat destruction.
   • The Thylacine (Tasmanian Tiger) was hunted to extinction by humans and suffered from habitat loss.
   • The Spix's Macaw became extinct in the wild due to habitat destruction and capture for the pet trade.

Section C: Long Answer Questions

8. Answer will vary.
   Example Response: Plastic pollution significantly harms marine life, as animals often ingest plastic debris or become entangled in it. For instance, sea turtles mistake plastic bags for jellyfish, leading to internal injuries or death. Additionally, microplastics can disrupt the food chain, affecting various species from plankton to larger marine animals.

9. Answer will vary.
   Example Response: Urban sprawl encroaches on natural habitats, reducing available land for wildlife. Measures to balance development and conservation include creating green spaces, wildlife corridors, and implementing sustainable urban planning practices that prioritize biodiversity.
