If we don't make sure everything is good and not take care of things, we will end up like this and we wont be able to fix most things. We have to take care of our plants, not get rid of more. I chose this picture because I feel like more people are taking down trees and that's what we need the most, we get oxygen by trees. Not controlling the social, agriculture and other things can make everything go wild and things not be taken care of .

I’ve watched few of amoeba sisters’ videos, when I don’t understand something their videos help out a lot. Maybe because its animations or its just showing every process with a picture (figure), it makes me understand it way better. Photosynthesis produces oxygen and plants and animals eat sugar which is glucose which makes atp after plants and animals eat it. After the process we get cellular respiration. The videos also compare the stages into stuff we have such as the thylakoids, they’re stacks of pancakes to granum.

In Georgia there are a lot of gymnosperm trees. Those trees are mostly what they call “naked seed” as they mention on the website of the university of Georgia, “The name gymnosperm is from Greek meaning “naked seed.” The gymnosperm group includes conifers, cycads, ginkgo, and gnetophytes with 12 major families, 84 genera, and more than 1,075 species scattered around the globe.” Where I used to live, there were many pinecones that were on the floor from the pine tree dropping. There was a lot of those trees around that area. They mention a lot of information according what type of trees Georgia has, “The cypress family in Georgia is represented by four tree species. The redwood family, which can be included within the cypress family by taxonomists, has two species in Georgia. Georgia has 21 native gymnosperm trees.” I’ve seen many conifers trees where I have lived. The website also mentions how many families and genera and even how many species there are.

Global warming can harm the grassland biome. Later on, it won’t feed the plants and trees enough water, rain, and the grassland won’t survive. Agriculture is a big factor that can cause a major shift in the grassland biome. By getting the soil people need having big crops can cause for the habitat to be lost for the wildlife. We need the chain to be in order, in order for everything to flow the right way. They need to fix the soil where it can grow back what it has lost and not destroy. They just leave the field they had destroyed and go to another one to do the same harm.

Many things changed, many impacts on plant domestication. In the diagram it shows how it impacted the genes from plants, the traits, the agriculture, and the technology. Humans can get diseases from the pesticides, it’s a health risk. In the article it mentions how the pests can cause such a problem for the plants, “Globally, crop losses from pests, pathogens and weeds amount to 25–40% of the production of our most important food crops [59]. Increased damages thus have real potential to not only decrease grower profits, but also significantly impact global food supply and human nutrition.” Different things happen with plant domestication.

On the article I found it mentions aspirin is the most popular they derived from a plant, "Indeed, nearly half of all human pharmaceuticals now in use were originally derived from natural sources. Perhaps the most famous example is aspirin, which evolved from a compound found in the bark and leaves of the willow tree and was later marketed by Bayer starting in 1899." I chose this article because I didn't even know that aspirin came from a plant. It's pretty interesting how something comes out of a plant or humans take it out to make something for us.

From the plant-choked jungles of Malaysia to the coral reefs of the Caribbean, scientists are combing the planet for cures to our most intractable maladies. Such bioprospecting is tedious workon average only one in thousands of natural compounds tested shows pharmaceutical promise, and only a handful of those ever make it to market. Yet despite the high risk of failure, researchers press on, driven by the realization that with millions of years of experience under her belt, Nature is the ultimate chemist.

Indeed, nearly half of all human pharmaceuticals now in use were originally derived from natural sources. Perhaps the most famous example is aspirin, which evolved from a compound found in the bark and leaves of the willow tree and was later marketed by Bayer starting in 1899. Some 50 years later, scientists identified anticancer compounds in the rosy periwinkle ( right), which pharmaceutical heavyweight Eli Lilly subsequently produced for the treatment of leukemia and Hodgkins disease. Other well-known examples include the cancer-fighting Taxol, isolated from the Pacific yew tree, and Aggrastat, an anticoagulant based on the venom of the saw-scaled viper from Africa.

Today many other compounds taken from Nature's medicine cabinet are showing promise (see sidebar). And with thousands of species as yet untapped for their chemical potions, it's tempting to compare bioprospectors to the proverbial kids in a candy store. But in fact, those sweet rewards sometimes come at tremendous cost. Researchers are increasingly finding themselves at odds with traditional healers in many parts of the world, who have long made use of plants and animals to treat various ailments, and with Nature herself, who does not typically part with anything without ecological consequences.

That there is a need for new drugs to combat AIDS, Alzheimer's and other ailments, however, goes without saying. In addition, researchers are under mounting pressure to find compounds to replace those that have become less effective. With bacterial resistance on the rise, for example, the world desperately needs new antibiotics. The same holds true for cancer drugs, which can lose their potency in a patient over time. And Nature may still be the best place to hunt for such lifesaving compounds.

Finding the Needle in the Haystack

With about 10 million species inhabiting the earth, how do scientists determine which ones contain potential panaceas? In many cases they are screening randomlya process that yields on average one useful drug for every 20,000 samples analyzed. But other researchers employ a different strategy, consulting indigenous people when possible. According to Conservation International, studies have shown that plants identified by locals are in fact up to 60 percent more likely to have pharmaceutical potential than their randomly collected counterparts.

Recently plants and sessile or slow-moving marine invertebrates such as sponges, corals and sea slugs have attracted particular attention because for these organisms, running away from a predator is not an option. Instead they have chemical defenses. And with a little tweaking, the potent toxins they produceas well as those manufactured by certain poisonous snakes, frogs and land invertebratescan actually save lives.

Of course, targeting a promising compound is only the first step. Before developing a drug from it, a renewable resource for the compound has to be established. This task poses an enormous barrier. Because these compounds often come from rare or slow-growing organisms, or are produced in minute quantities, harvesting the source organisms in sufficient amounts may be unrealistic.

To address this problem, researchers usually try to make synthetic derivatives. But sometimes synthesis proves impossible, or uneconomical, as in the case of Ecteinascidin-743, an anticancer compound currently in clinical trials that comes from a creature called a sea squirt. Scientists from CalBioMarine Technologies in Carlsbad, Calif., have developed a method of culturing the animal, going so far as creating an artificial version of the mangrove roots it settles on in the wild. In other cases, simply culturing cells from the source organism is sufficient.

Once developed, these drugs, as with all proposed pharmaceuticals, must pass a battery of rigorous test that evaluate their safety and efficacy in animals and then humans. This step, too, can take its toll, especially on start-up companies. Take, for example, the case of Shaman Pharmaceuticals, a once-promising company armed with a product poised to treat people suffering from chronic diarrhea. Their drug, Provirderived from the sap of croton, a common Amazonian treedid so well in two years of clinical trials that the FDA granted it fast-track status, requiring only one final Phase III trial instead of two. When the FDA later decided to demand a second Phase III trial, though, Shaman couldn't afford it. Today the company sells dietary supplements.

Bioprospecting or Biopiracy?

In addition to the difficulties posed by the research itself, the scientists and pharmaceutical companies hunting for natural miracle drugs face critical ethical dilemmas. In Brazil, for example, officials have expressed concern over the possibility that the scientific demand for plant samples has led to plant smuggling. And indigenous groups around the world worry that in the race to patent Nature's million-dollar molecules, science is stealing their intellectual property.

Indeed, according to a report that appeared earlier this year in the Atlanta Journal and Constitution, even a project that aimed to share future profits with the native peopleMayans in Mexico's Chiapas statehas floundered, owing to disagreements over who owns the plants, folk knowledge and commercial rights to whatever drugs might result from the collaboration.

Other efforts to ensure these often poorer nations benefit from visits from bioprospectors have had happier outcomes. In South America's Suriname, for instance, Bristol Myers-Squibb, scientists and conservationists from the Missouri Botanical Gardens, the Virginia Polytechnic Institute and Conservation International helped to establish a four-million-acre reserve. Conservation International has also been active in helping the governments of Madagascar and Indonesia to develop policies aimed at maintaining national sovereignty over their biological resources.

Bioprospecting during the past decade has yet to turn up a blockbuster drug, but a number of naturally derived pharmaceuticals are being evaluated in human trials. These include compounds ranging from Immunokine, derived from the venom of the Thailand cobra, which may effectively combat multiple sclerosis, to calanolide A, an anti-HIV agent retrieved from a Malaysian plant. Ziconotide, a potent pain reliever extracted from the tropical marine cone snail, has come particularly far and is awaiting FDA approval. Once approved, Ziconotide will become the first marine-organism-based pharmaceutical.

In many cases, though, the environments in which potentially healing organisms live are being destroyed. Estimates place the number of species screened for their medicinal properties at a mere 1 percent, yet each year more than 30 million acres of tropical forest are lost. Human activity is taking its toll on the oceans, too, in the form of pollution and overfishing. Such large-scale destruction of our planet's complex ecosystems will no doubt come back to haunt usif for no other reason than the fact that with every species lost, Mother Nature is taking potentially lifesaving chemical formulas to the grave.

Crash course gives important and very nice explanation of the agriculture revolution. Burning coal was the source of heat, where a lot started. The steam engine was made to carry water to move to another area. In the 19th century, engineering was where more things was being formed.
