Industrialized nations and are greatly responsible for deforesting Earth, although nations such as Japan have been exporting the devastation, as foreign forests are razed and shipped to Japan, while Japan treats its forests as sacred groves. But also, the poor in former colonial nations have been pushed to ecosystem margins. The prime arable land is usually owned by local oligarchs or foreign corporations; they often raise crops for export to the industrialized nations. . The peasants farm marginal lands, often hillsides, which not only devastate the last refuges of species driven into the hills, but it also erodes the hillsides, , which happened in the Old World long ago. Those dynamics, particularly habitat destruction, are largely behind today’s accelerating Sixth Mass Extinction, also called the . This pattern also extends back for , not just since the ice sheets melted in this latest interglacial interval. The reached 70% or more of global species going extinct. According to a recent estimate, for the human-caused extinction. Other estimates have this level being reached as early as my lifetime, while others think it will be reached in a . The current extinction rate is thought to be higher than those of all previous extinction events other than the one that . Humanity may “achieve” . Biologists and climate scientists are stupefied, and the global propaganda machine chugs along, making everything seem normal, while “scientists” in their employ work long and hard to , , and the rest, in a kind of Potemkin Earth strategy, gleaning profits and playing power games until the end.

Food Science at UGA is an excellent major for students who like science and want to see practical applications of their knowledge. Students take courses across several disciplines including (1) Biology – to understand the natural processes of fresh plant and animal products as they lose freshness; (2) Chemistry – to determine the quality and quantity of vitamins, minerals, and proteins in our foods when we eat them; (3) Microbiology – to understand the causes of food poisoning; and (4) Math and (5) Engineering – to help develop ways to treat foods, calculate expiration dates, and prevent outbreaks. Food science students apply this knowledge in a series of practical courses that prepare them for careers in the food industry or governmental agencies, tailoring the major into either a Business or Science, Technology, & Engineering emphasis.

A free radical is an atom, molecule, or ion with an unpaired valence electron or an unfilled shell, and thus seeks to capture an electron. The used to create ATP in a mitochondrion leaks electrons, which creates free radicals, which will take that electron from wherever they can get it. creates some of the most dangerous free radicals, particularly the . The more hydroxyl radicals created, the more damage inflicted on neighboring molecules. Another free radical created by that electron leakage is , which can be neutralized by , but there is no avoiding the damage produced by the hydroxyl radical. Those kinds of free radicals are called (“ROS”). ROS are not universally deleterious to life processes, but if their production spins out of control, the oxidative stress inflicted by the ROS can cripple biological structures. ROS damage can cause programmed cell death, called , which is a maintenance process for complex life. Antioxidants are one way that organisms defend against oxidative stress, and is a standard antioxidant. Antioxidants usually serve multiple purposes in cellular chemistry, and antioxidant supplements generally do not work as advertised. They not only do not target the reactions that might be beneficial to prevent, but they can interfere with reactions that are necessary for life processes. Antioxidant supplements are blunt instruments that can cause more harm than good.

Photosynthesis Essay Ap Biology Scoring Guide

For this essay’s purposes, the most important ecological understanding is that the Sun provides all of earthly life’s energy, either (all except nuclear-powered electric lights driving photosynthesis in greenhouses, as that energy came from dead stars). Today’s hydrocarbon energy that powers our industrial world comes from captured sunlight. Exciting electrons with photon energy, then stripping off electrons and protons and using their electric potential to power biochemical reactions, is what makes Earth’s ecosystems possible. Too little energy, and reactions will not happen (such as ice ages, enzyme poisoning, the darkness of night, food shortages, and lack of key nutrients that support biological reactions), and too much (such as , ionizing radiation, temperatures too high for enzyme activity), and life is damaged or destroyed. The journey of life on Earth has primarily been about adapting to varying energy conditions and finding levels where life can survive. For the many hypotheses about those ancient events and what really happened, the answers are always primarily in energy terms, such as how it was obtained, how it was preserved, and how it was used. For life scientists, that is always the framework, and they devote themselves to discovering how the energy game was played.

There is also evidence that life itself can contribute to mass extinctions. When the eventually , organisms that could not survive or thrive around oxygen (called ) . When anoxic conditions appeared, particularly when existed, the anaerobes could abound once again, and when thrived, usually arising from ocean sediments, they . Since the ocean floor had already become anoxic, the seafloor was already a dead zone, so little harm was done there. The hydrogen sulfide became lethal when it rose in the and killed off surface life and then wafted into the air and near shore. But the greatest harm to life may have been inflicted when hydrogen sulfide eventually , which could have been the final blow to an already stressed ecosphere. That may seem a fanciful scenario, but there is evidence for it. There is fossil evidence of during the Permian extinction, as well as photosynthesizing anaerobic bacteria ( and ), which could have only thrived in sulfide-rich anoxic surface waters. Peter Ward made this key evidence for his , and he has implicated hydrogen sulfide events in most major mass extinctions. An important aspect of Ward’s Medea hypothesis work is that about 1,000 PPM of carbon dioxide in the atmosphere, which might be reached in this century if we keep burning fossil fuels, may artificially induce Canfield Oceans and result in . Those are not wild-eyed doomsday speculations, but logical outcomes of current trends and , proposed by leading scientists. Hundreds of already exist on Earth, which are primarily manmade. Even if those events are “only” 10% likely to happen in the next century, that we are flirting with them at all should make us shudder, for a few reasons, one of which is the awesome damage that it would inflict on the biosphere, including humanity, and another is that it is entirely preventable with the use of technologies .
