  1. Things thatSCIENTISTS know,FARMERS knowI knowANDYOU DON'T KNOW about Animal Agriculture By; Jenny.W 2-3

  2. What is it? • Animal agriculture - the practice of raising animals for the purpose of using the animal for food, production of the products, or recreational use.

  3. Of the 71% habitable land on earth… • 50% is used for agriculture • 77% of that 50% is used for live stocks

  4. Habitat loss • Making space to farm animals destroy forests and natural habitats of wild animals.  Some animals can only live in that particular area. So, when their habitats are destroyed, they have nowhere else to go.  This will put that species of animal in the danger of extinction

  5. Extinction of birds • "Luisa Arnedo, a biologist and senior programs officer for the National Geographic Society, explained that birds can be especially susceptible to extinction when they face habitat loss because they live in ecological niches, eating only a specific prey or making nests in specific trees." (Gibbens, 2018) • “As soon as the habitat is gone, they're gone too,” (Arnedo, 2018)

  6. Declination of Bird Population from 2009 to 2017 in France

  7. Summary • Habitats are destroyed when we cut down forests to make room to feed live stocks. • This endanger certain species of animals that can only live in certain environment • Example: Birds • Due to the loss of habitats bird biodiversity and population has declined drastically.

  8. How methane contributes to animal extinction

  9. “18% of all greenhouse gas come from animal agriculture” Methane is one of them (UBC, 2019)

  10. “Methane has 21 times more climate changing power than co2” (reveal, 2012) 27% of methane that come from livestock farming (Bousquet, P. et al, 2006)

  11. That’s 90 million tons of methane each year [13] More than that produced by 22 million cars per year

  12. What does methane do?

  13. What does global warming do? • Yes, it does warm up our earth • Animals that cannot adapt to changes brought by global warming will disappear. “Recently, Sinervo et al. (2010, Science, 328: 894-899) reported declines of lizard biodiversity due to local warming trends and altered thermal niches” (Kubisch, E. L., Corbalán, V., Ibargüengoytía, N. R., Sinervo, B., 2019)

  14. Animals that’s gone extinct/endangered due to global warming

  15. Polar bears – top predator • Diet: beluga whales, walruses, any animal they can get. • Due to direct effects of global warming, “Sea ice is forming later in the fall and disappearing earlier in the spring. “ (Dell'Amore, 2014) • But due to the ice disappearing, the polar bears can no longer hunt on places they are used to – ice- instead, they have to find alternative food sources on land. Some polar bears have no problem to hunt without ice, while many others do. But it is the sudden change in temperature between ice land and shores which polar bears have trouble with. If they cannot adapt to the new temperature, they are stuck on the ice where food is unavailable. • Polar bears are at the top of the food chain. They, like other omnivores, help regulate the population of the animals they prey upon. Without them, population of certain species of animals may increase significantly. Then there may not be enough food to go around for that species and they might disappear too. And the loop will continue to repeat.

  16. Orange-spotted filefish • Directly affected by global warming • Highly sensitive warm water • “The animal went extinct in Japan during an episode of warmer ocean temperatures in 1988.” (Dell'Amore, 2014)

  17. How animal agriculture drives extinction

  18. What can the world do?

  19. What you could do • Go vegan and no dairy for 1 day a week

  20. Your impacts
