CARBON DIOXIDE

Carbon Dioxide harms ocean life. The ocean has absorbed almost half of the carbon dioxide that humans have made in the last 200 years, which is about 118 billion metric tons. Carbon dioxide harms coral and free-swimming algae. The carbon dioxide makes it more difficult for coral to form their outer shells. How does the ocean gather carbon dioxide? When the currents stir the ocean by pulling deep water from the surface, where the carbon dioxide gets trapped. Carbon dioxide causes the greatest threat to the species that live on the top of the ocean water. That’s because that is where the currents gather the carbon dioxide. Cars can also cause pollution to the ocean, not directly, but indirectly. The car’s exhaust (which is carbon dioxide) is evaporated, which can cause acid rain, and will eventually make is way into the ocean. It’s the same thing with boat gasses and agricultural pollution (except with pesticides).

Carbon dioxide (chemical formula: CO2) is a chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth's atmosphere in this state.

Carbon dioxide is used by plants during photosynthesis to make sugars which may either be consumed again in respiration or used as the raw material to produce polysaccharides such as starch and cellulose, proteins and the wide variety of other organic compounds required for plant growth and development. It is produced during respiration by plants, and by all animals, fungi and microorganisms that depend on living and decaying plants for food, either directly or indirectly. It is, therefore, a major component of the carbon cycle. Carbon dioxide is generated as a by-product of the combustion of fossil fuels or the burning of vegetable matter, among other chemical processes. Large amounts of carbon dioxide are emitted from volcanoes and other geothermal processes such as hot springs and geysers and by the dissolution of carbonates in crustal rocks.

ocean pollution

Pollution in the ocean is a major problem that is affecting the ocean and the rest of the Earth, too. Pollution in the ocean directly affects ocean organisms and indirectly affects human health and resources. Oil spills, toxic wastes, and dumping of other harmful materials are all major sources of pollution in the ocean. People should learn more about these because if people know more about pollution in the ocean, then they will know more about how to stop pollution.
Oil pollution is very bad for the ocean and environment. Thirty seven million gallons of oil are accidentally spilled into the ocean every year by tankers. Even more oil gets into the ocean from non-accidental sources. Sixty million gallons of oil end up in the ocean every year. That’s a lot of oil! The oil “glues” birds’ feathers together, clogs fishes gills, and blocks out sunlight (making it harder for plants underwater to go through photosynthesis). Oil pollution also slows down coral reefs growing and their reproduction. Coral reefs are also very sensitive to oil, especially crude oil. Click here for a pie graph on oil pollution. Also, click here for another chart on how many millions of gallons of oil end up in the ocean each year.

What are toxic wastes?

Toxic wastes are poisonous materials that are being dumped into the ocean. They harm many plants and animals in the ocean and have a huge impact on our health. Toxic waste is the most harmful form of pollution to sea life and humans. When toxic waste harms an organism, it can quickly be passed along the food chain and may eventually end up being our seafood. In the food chain, one toxic organism gets eaten by another, larger animal, which gets eaten by another animal, and can end up being our seafood. Toxic waste gets into seas and oceans by the leaking of landfills, dumps, mines, and farms. Farm chemicals and heavy metals from factories can have a very harmful effect on marine life and humans.

selamat datang di bumi

selamat datang di bumi yang gersang ini. Lihatlah ke kiri: taman gersang, di kanan mobil,motor berlalu-lalang. Hirup udara yang sudah bercampur dengan asap knalpot,asap industri, debu. Tak ada pohon disekitar yang bisa menetralisir udara, sampah plastik berserakan. Pohon-pohon ditebang dan tak pernah ditanami kembali.
Sampai kapan kita cuma berdiam diri tanpa ada usaha untuk menyelamatkan bumi ini. Bumi tempat kita tinggal, tempat kita hidup. Tuhan telah memberi kita bumi yang dulunya sangat indah ini. Harusnya kita bisa menjaga bumi kita yang indah ini.
Saya sangat cinta bumi ini, walaupun saya belum bisa berbuat banyak tetapi saya akan berusaha untuk menjaganya.

Pollution

Air pollution from World War II production.

Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms .[1] Pollution can take the form of chemical substances, or energy, such as noise, heat, or light energy. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels. Pollution is often classed as point source or nonpoint source pollution. The Blacksmith Institute issues annually a list of the world's worst polluted places. In the 2007 issues the ten top nominees are located in Azerbaijan, China, India, Peru, Russia, Ukraine and Zambia.
History

Throughout history from Ancient Greece to Andalusia, Ancient China, central Europe during the Renaissance until today, philosophers ranging from Aristotle, Al-Farabi, Al-Ghazali, Averroes, Buddha, Confucius, Dante, Hegel, Avicenna, Lao Tse, Maimonedes, Montesquieu, Nussbaum, Plato, Socrates and Sun Tzu wrote about the pollution of the body as well as the mind and soul.

Prehistory

Humankind has had some effect upon the environment since the Paleolithic era during which the ability to generate fire was acquired. In the Iron Age, the use of tooling led to the practice of metal grinding on a small scale and resulted in minor accumulations of discarded material probably easily dispersed without too much impact. Human wastes would have polluted rivers or water sources to some degree. However, these effects could be expected predominantly to be dwarfed by the natural world.

Ancient cultures

The first advanced civilizations of Mesopotamia, Egypt, India, China, Persia, Greece and Rome increased the use of water for their manufacture of goods, increasingly forged metal and created fires of wood and peat for more elaborate purposes (for example, bathing, heating). The forging of metals appears to be a key turning point in the creation of significant air pollution levels. Core samples of glaciers in Greenland indicate increases in air pollution associated with Greek, Roman and Chinese metal production[2]. Still, at this time the scale of higher activity probably did not disrupt ecosystems.
