Biodiversity loss

Biodiversity loss

By Nathan Hull and Karl Stout


Definition

Definition

  • The loss of diversity among and within plant and animal species in an environment

Ecological cycle: Nitrogen cycle


Biodiversity loss

Pros

  • Introduction of new and exotic species

  • People don’t change the way of living due to helping out with naturally occurring process

  • More land free for humans

  • Genetic Diversity


Introduction of new and exotic species

Introduction of new and exotic species

  • There will always be a replacement for the animal diversity that is lost.


People don t change the way of living due to helping out with naturally occurring process

People don’t change the way of living due to helping out with naturally occurring process

  • Traditional cultures of people will not change for a while

  • Different cultures cause the loss of biodiversity. (fishing, hunting, etc.)


More land free for humans

More land free for humans

  • More human societies because more cities can be built

  • More jobs leading to a better economy


Genetic diversity

Genetic diversity

  • How same species become different and evolve through genes

  • If biodiversity loss happens, then eventually the species will evolve and have a new biodiversity


Biodiversity loss

Cons

  • Greatly effects economy

  • Puts species at risk of extinction


Greatly effects economy

Greatly effects economy

  • Ex. The coral reef provides food, jobs, recreation, and other income sources for more than 500 million people worldwide. Due to biodiversity loss, 70% of coral reefs are threatened or destroyed

  • Over-depletion of fish stocks caused by agricultural chemicals to water has risen the likelihood of a severe $10-$50 billion impact on businesses


Puts species at risk of extinction

Puts species at risk of extinction

  • Of world’s 5,490 mammals, 78 are extinct, 188 are critically endangered, 540 are endangered, and 492 are vulnerable


Solution

Solution

  • As of right now, there is no one solid solution for biodiversity. Proposed ideas are, holding conventions to help educate people on the risks of biodiversity loss and get contributors for the fight against biodiversity loss.
