Summary of Conservation for the people

The article starts out focusing on why we should protect the ecosystem for us and on what ecosystems we should preserve that will most benefit us. Next the article talks about the two strategies of ecosystem preservation Hot spot strategy and the Ecosystem services strategy. The hot spot strategy is where we try to preserve ecosystems with lots of biodiversity like the rain forest before ones with low biodiversity like the dessert. The ecosystem services strategy is where we preserve ecosystems that serve us best before all the other, like ecosystems that have lots of tourism. One of the other things that the article talks about is preserving habitats that protect us from storms like the mangroves. If not for the mangroves Florida would be a lot more threatened with tropical storms like hurricanes. The mangroves act like a barrier to tropical storms. Another such thing that needs to be protected is clean water. If we pollute up stream it makes the water for the rest of the river unfit for drinking, which causes a host of problems. To sum it all up the article is focusing on what we can do to preserver the environment that will be beneficial to us. It gives many good points of how nature is important to us and why we need to preserve it.

What are ways in which preserving biodiversity locally might have a global effect?
If we preserve the environment locally others will notice us, then those people might do the same thing and people will see them. pretty soon we have a global effect. Also If we preserve local environment we could inspire someone to wright a law that will protect the environment.

How do habitat destruction and loss of species effect more than just one area?
It can effect more than one area if other areas depend on that area for resources. For example if a mountain pond becomes contaminated with a harm full substance from a factory. And that substance kills plants and animals, and a deer drinks from the pond and the is eaten by a mountain lion, and then scavengers eats the mountain the substance has contaminated a whole new area.

How does preserving biodiversity enhance the life of people?
First of all we depend on NATURAL resources to survive. Key word NATURAL. So it stands to reason that we would want to preserve nature. If not because we should care, then because we need certain things from nature. Also if those two things aren't enough of a reason then we should preserve nature for future generations.

Notes n' Stuff

Demo 1.)

Hypothesis: If we set the rubbing alcohol on fire the bottle will ether explode or belch flames.

Conclusion: It belched flames. Not only that it also went flying across the room and impacted the teachers desk. Wow. Also it made a nice woshing noise.

Combustion effects climate change by creating more green house gases which in turn heats up the earth. This effect is known as the green house effect. Due to the growing amount of green house gases in the atmosphere green house effects have increased, causing global warming.

Demo 2.)

Hypothesis: If we introduce the gas to the fire, then the fire will flare up and gain size.

Conclusion:It immediately put the flame out. I feel stupid I completely forgot that flame requires oxygen. By relecing the co2 we took the oxygen away. AKA we took away its fuel.

Carbon Dioxid: Carbon Dioxid is not classified as a pollutant due to the fact that it is naturally present in the atmosphere. Also it is a necessity to plants to preform the process of photosynthesis, but like all gases to much of it can be toxic.

Demo 3.)

Hypothesis: If we introduce the hydrogen to the flame, then the flame will grow in size.

Conclusion: I was correct. The flame used the hydrogen as fuel just as I predicted. It was very cool the way the acids bubbles below the flame.

Ocean energy: Waves generate electricity. Renewable source of energy.
Net energy: Net energies are basically how much you get out of your energy investment. If a net energy of something reaches 0 then their is no longer any gain. The net energy of oil has been decreasing for years.
Wind energy: Wind energy is the process of wind turing turbines to generate energy. Wind energy is the most efficient energy it gives 18 times as much energy as is invested, and it is renewable.
Solar energy: Solar energy is the process of harvesting energy for the sun's rays. Solar energy is often harvested using panels. It is a renewable resource, but very costly.

Article 3 Summary

I really thought that the article was very interesting how it talked about the effects of Chernobyl on peoples health. It talked mostly about the different diseases that the radiation caused to thoughts who were exposed to it. I did not know that any amount of radiation in your body is harmful, I always assumed that you had to be exposed for a certain amount of time before there would be any effects. Also I did not know a lot about how radiation actually causes all of the effects that it does, however now I have a much better understanding of it. It was quite a lot of information to process all at once.

Questions for the Panal

1.Is the love canal safe?
2. Why or why not.
3. What exactly are the precations taken against contamination.
4. How can we been sure that there are not lingering contaminets?
5. If the government took as long as they did to admit the problem how can we trust them now?

8-30-10 catalyst

1. It started with the blizzard 77 and the wet sesson that followed which caused canal system to flood pushing the chemicals to the surface.

What I thought about the oil spill video.

I thought that it was really powerful in the sense that it made you stop and think, "Is this really happening? Are they really dumping all those harmful chemicals into the ocean?" What I knew before I watched the video was that BP's dispersants weren't doing the best job cleaning up the oil; however, now I know there is much more to the story. I now know that the dispersants are actually making the oil all the more dangerous by allowing it to penetrate skin. Furthermore, the dispersants makes the oil harder to see which makes it even more difficult to clean up. Some good you're doing BP! You made this mess now you're only making the problem worse. To sum it up I really think that I learned a lot from the presentation about the dangers of oil to us and to the wildlife.
