Due Friday May 17th
(You will share it with the class and school after EQAO)
You will be working in groups of 3-4 people to research and present information on a threat to biodiversity. We have briefly discussed each of these threats in class. Resources for research will be provided by Mrs. McCord, but you made want to expand on it. Your presentation will include a Bristol board with the following information:
You will also have a slideshow/power point running with images relating to your topic.
Your presentation should be colorful and eye catching, with big bold titles and facts that are easy to read and understanding. If possible, use props to support your display. You may want to include graphs or charts to help illustrate your information.
Your purpose is to inform your audience about the threat, and then persuade them to take action to help correct it.
Be ready to explain your topic to our guests and answer any questions.
*A rough draft of your Bristol board design along with your outline must be shown to Mrs. McCord by May 10th.
Number your top 3 choices with your group.
As pollinators, bees play a part in every aspect of the ecosystem. They support the growth of trees, flowers, and other plants, which serve as food and shelter for creatures large and small. They are key players is preserving biodiversity. Currently, the number of pollinators across the planet is shrinking. This causes a very real threat to our ability to grow food, and to many key ecosystems.
Deforestation and habitat loss
Deforestation is a direct cause of extinction and loss of biodiversity. An estimated 18 million acres of forest are lost each year, due in part to logging and other human practices, destroying the ecosystems on which many species depend. Tropical rainforests in particular, such as the Amazon, hold a high percentage of the world's known species, yet the regions themselves are in decline due to humans. You could also look at the deforestation of the rainforests of British Columbia for a Canadian view.
Overexploitation – hunting, fishing, etc.
Overhunting, overfishing and over-harvesting contribute greatly to the loss of biodiversity, killing off numerous species over the past several hundred years. Poaching and other forms of hunting for profit increase the risk of extinction; the extinction of an apex predator — or, a predator at the top of a food chain — can result in devastating consequences for ecosystems.
An invasive species is a living thing that gets introduced to a new place that it does not normally belong to and to which it typically causes harm. The introduction of non-native species into an ecosystem can threaten local wildlife (either as predators or using up resources), affect human health and upset the balance of an ecosystem. Due to a lack of natural predators, invasive populations grow quickly and outcompete native species for resources, disrupting food webs and even endangering some species. Some invaders threaten human health. For instance, introduced mosquitoes can carry diseases such as the West Nile and Zika viruses.
Keystone species – sharks or wolves (pick one)
A keystone species is a plant or animal that plays a unique and crucial role in the way an ecosystem functions. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf, are also apex predators. For this topic, look at how the endangerment (or overpopulation) or either sharks or wolves threatens biodiversity in their ecosystem.
Changes in climate throughout our planet's history have, of course, altered life on Earth in the long run — ecosystems have come and gone and species routinely go extinct. But rapid, manmade climate change speeds up the process, without affording ecosystems and species the time to adapt. For example, rising ocean temperatures and diminishing Arctic sea ice affects marine biodiversity. Climate change forces species to adjust. But many are not able to cope, causing them to die out. Differing temperatures, amounts of snowfall or rainfall and a variety of other symptoms of climate change can all affect ecosystems in a given area.
