Living ResourcesThe Lives We Depend On By KarminDhaliwal, Ashley Biddlecombe, and Olivia Zander
We Need This Stuff! • As humans we rely on the natural environment • Living resources, animals and plants (Fauna and Flora) sustain us.
Connections We Depend On • Unfortunately, we are destroying many species of Flora and Fauna that we depend on for things such as food, medicine, building supplies, aesthetic value, tourism, oxygen, filtration, rubber.... The list is very long. And because all species are connected in a vast food chain, when one species is lost it can affect many other species in unforeseen ways. The multitude of complex relationships that exist within an ecosystem are very delicate.
So why are we destroying it? • It seems that humans tend to care more about their own needs than those of animals and plants • 3 main factors that lead to Canadian endangered species are over exploitation, habitat destruction and pollution. • Over exploitation: We use some animals/plants so much that they die off, and are unable to be brought back. We do this to make money, and to sustain the ever growing human population • in other words we harvest a renewable resource to the point of no return • Habitat Destruction: Humans need space to live, grow food, work, play, and learn. All of this takes away space from flora and fauna. We also need wood to build stuff. We cut down forests to serve our own needs. • Pollution: We also wreck a lot of wild areas with pollution, and other contaminants.
What’s the Biggest Threat to Flora and Fauna? • The main reasons for species loss today is the change to their habitats • Our world is rich in species, and most of them are found in the Tropics • This is why deforestation in places such as the Amazon rainforest is so unfortunate. The lost habitat means we also lose species. • http://www.youtube.com/watch?v=Txa-XcrVpvQ&NR=1&feature=endscreen • http://www.youtube.com/watch?v=ejmuhOJyPzw
So What Does it Mean to Be An Animal at Risk? There are 3 levels • Endangered species - A population of organisms which is at risk of becoming extinct because their numbers are very low and they face threats such as a changing habitat. • Extirpated - To destroy or remove completely a species from a certain area. • Extinct - the end of an organism or of a group of organisms, normally a species, they no longer exist.
Who has already become Extinct? • Since 1600, 90 species of birds and 40 species of mammals have become extinct • http://www.youtube.com/watch?v=sq89Nd0jeaU
What Have We Done!? Fish Tomatoes? • http://www.youtube.com/watch?v=XY3w73d6JTI&feature=related • The green revolution is the modifying of domestic species to suit humans own needs. • Over thousands of years through mutation and recombination we have modified the organisms we rely on. • Positives from the green revolution: we are able to grow crops with higher yields that are drought resistant, and animals that weigh more. • Negatives: the complex nature of the changes involved. Social problems arise because farmer and capitals are favoured. This has widened the gap between rich and poor even more. • http://www.youtube.com/watch?v=kE2OFfmrJRI
So What Can Humans do? • To prevent a further decline in endangered species, numbers must be boosted with captive breeding programs, and habitats protected and enhanced. We can create laws to stop poachers, use selective logging techniques to save forests, reduce our consumption of meat to save land, implement laws that allow for sustainable use of Flora and Fauna, set restrictions of agricultural boundaries, look into vertical farming, and care. We must recognise the value in life of all forms, because we really do need plants and animals to survive and thrive.
Atlantic Sturgeon declared an endangered species CURRENT EVENT
What • As of January 31st 2012 the Atlantic sturgeon was declared an endangered species. • This provides greater legal protection then just some petition that the natural resource and defence put in effect.
When • Fishing the Atlantic sturgeon has been illegal for more then a decade. • But it was declared endangered on January 31st 2012 when the NOAA put it under the endangered species act.
Who • NOAA put the Atlantic sturgeon under the endangered species act. • Types of Atlantic sturgeon under act are as followed: The Chesapeake Bay, New York Bight, Carolina, and South Atlantic populations of Atlantic sturgeon.
Where • This is happening all over the world • No one is allowed to fish the Atlantic Sturgeon
Why • Atlantic sturgeon are large, slow-growing, late-maturing, long-lived, estuary-dependent fish that live most of their lives in salt water, but hatch and spawn in freshwater, a lot of their time is spent travelling.
Conclusion • The Atlantic Sturgeons population is decreasing rapidly because they can not reproduce as fast as they were being fished out of the ocean. Even though they were not fished for over ten years it was not good enough to help them repopulate. Lets hope that now that they are a endangered species that their numbers will grow.
Questions • Do you think there is anymore they can do then just list the Atlantic sturgeon as an endangered species? What is that? • Why do you think they did not list the Atlantic Sturgeon as an endangered species before now?
