Verge of the next Mass Extinction
http://www.biologicaldiversity.org/programs/biodiversity/elements_of_biodiversity/extinction_crisis/
In our class we discussed radioactive dating and how the properties of Carbon-14 helped scientists uncover the reality of mass extinctions. We spent some time going over some major mass extinctions in our history that wiped out large populations of animals affecting global biodiversity. We have also talked about the importance of a stable environment, which creates stable ecosystems, which leads to a stable biosphere. This article puts an interesting spin on our current environmental problems. It states that the earth and its ecosystem right now is taking a disastrous dive towards extinction. A healthy planet should have about 1-10 extinct species a year but human activities and deforestation has caused that number to spike to up to 10000 species going extinct every year. This is a major problem, maybe not for our generation but for generations in the future. The lack of biodiversity for future generations will cause mass environmental problems. This article really gives readers the sense of the rate in which we are cutting down, burning, and polluting the world. The effect of humans has really taken a toll on the world and it won't be long before the world hits that big reset button.
I hope you enjoyed this article as much as I did, I found it really interesting and a great eye opener to how bad the pollution problem really is. Maybe us as the younger generation can take that first step towards saving our planets biodiversity.

When the next mass extinction is complete, what percent of the human population will be wiped out?
ReplyDeleteThe problem with this extinction is that it's caused by the humans. The lack of diversity will affect us in all sectors. It might kill agriculture, cattle, medicine. If it will completely wipe us out is unclear because us as humans can adapt but things will certainly not be the same. But keep in mind we're not lizards hiding under a rock, we can learn and survive.
DeleteIs the lack of biodiversity the only major factor for the future mass distinction? If so does that apply to mammals, plants, and aquatic animals alike?
ReplyDeleteThe problem isn't the lack of biodiversity, the problem is us humans harming the environment. The lack in biodiversity is the effect of this action and this effect will harm everything in our biosphere.
