This is the first time I been to American Museum of Natural History. I find very fascinating and I definitely will revisit when the semester is over. That way, I will have enough time to visit all the halls.
There is a lot of things to learn and spending one day in the museum is not enough. The first hall I visit was the Hall of Biodiversity. This hall is about all living creature are living on earth and animals are constantly interacting within our enivronments. Each animals live in different enivronments and habitats. The benefits of biodiversity is that human rely on food, fuel, fiber, medicine and heavily on natural product. All life reqiures clean air, water and food. One thing that most attract me is the Extinction and Biodiversity Loss. It is a list of animals that are extincted. Some of them live and die without any of our knowledge of learning them. A sudden change in our climate will lead to animal extinction and new animal will take over. It takes millions of years to recovery the process. What we doing in our enivronments is human are changing the ecosystem due to globe warming. Species are disappearing at a rapid rate. The coastal pollution about the "Red tides" was very disturbing to me. I never see Red tides that cause widespread of distroying the coral reefs, frquent closing of beaches. Red tides are link to pollution from industry and sewage. The largest depletion of our ozone layer is over in Antarctica. I'm afraid that if our ozone holes gets any bigger, all living things will get skin cancer including humans. I didn't know that Mexico City is one of largest polluted city in the world. The thick smog blind the city. At least laws and regulation are pass to protect the enivornment.
Our next hall we need to visit is the Warburg Hall of New York State Environment. Before enter the Warburg Hall of New York State Environment we need to pass by the North American Forests. The professor recommend class to see the Big Tree in the California Sierras that was cut down in 1891. It was very sad that people will do such a thing. What so fascinating was this Giant Sequoia Trees is fire proof and it can survive throw many generation. The diameter of the tree was enormous and it shows clear view of the tree rings.
The Warburg Hall of New York State Environment hall talks about the importants processes of soil creation and using natural fertilizers to grow crops. Since all the environmental issues are happen among us, we cannot pollute our soil and water cycle. Our soil creates foods for our eating.
The Hall of Spitzer Hall of Human Origins is about our great ancestors evolve into humans. We do have similar appearance as due human fossil and we came long way evolve into modern human. Since human came a long way, soon human will extinct if we continue to contaminate our environment. What Stephen Hawkings will said "I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planets. But I'm an optimist. We will reach out to the stars." I'm very pessimistic how our great grand children will say when we distroyed our planet.
My last stop was Gottesman Hall of Planet Earth. This halls is very similar to the movie of Inconvenient Truth by Al Gore. The museum give us a live version of the Green House global warming effect. Especially when scientists drills the ice deep down and collect it to measure the temperature every year date back in 1900s. The image reminded me when I read the Inconvenient Truth. Sudden change in climate will result in great danger. For example, hurricanes are getting stronger than ever.
The museum did a great job of making every animals, plants, the background and so on very real to an extent that you don't have to image it. It feel so real and alive. We need to be more active and start going GREEN!!!
Pesticides are spray in the air when planes come across the plantations. An when it sprays some of the pesticides are carried by wind and contaminate certain areas. Pesticides can causes water pollution and soil contamination. Thats why the Environmental Protection Agency (EPA) have to step in to regulate the proper usages of pesticides. Some people are concerns that pesticides that use on our food crops can be dangerous in the long term effects. The residue after the farmer spray in there crops will remain in our environment.
When purchese fruits and vegetables, waste it thoroughly with water and use a potato peeler to peel of the skin. Here is websites says, which fruits or veggie has the most pesticides on it: http://www.foodnews.org/. If you are extremely want to eat healthy, please look for a sign that says, Certified Organic Growers for vegetables and fruits, but it will cost you extra $$$. Anyway, Happy Thanksgiving!!!! 
This is the website http://www.epa.gov/pesticides/factsheets/securty.htm concerning the usage of pesticide in our foods.
