  • Though it sounds like a classroom assignment from Hogwarts School of Witchcraft and Wizardry, weather modification programs have been around for more than 50 years.
  • The problem is there are too many factors that affect the weather, making naturally occurring phenomena difficult to separate from man-made triggers.
  • "There was no strong scientific base for changing the weather."

  • Determined to prevent rain from dampening the spirits -- not to mention the crowds -- on opening day ceremonies, the government plans to seed any threatening clouds with chemicals to dispel, or at least delay, rainfall.

  • n experiments, the cream-based ultra-violet (UV) filters -- used to protect skin from the harmful effects of sun exposure -- caused bleaching of coral reefs even in small quantities, the study found.
  • But some 60 percent of these reef systems are threatened by a deadly combination of climate change, industrial pollution and excess UV radiation.
  • The new study, published in U.S. journal Environmental Health Perspectives, has now added sun screens to the list of damaging agents, and estimates that up to 10 percent of the world's reefs are at risk of sunscreen-induced coral bleaching.

  • Chemical compounds in sunscreen and other personal skin care products have been detected near both sea and freshwater tourist areas. Previous research has shown that these chemicals can accumulate in aquatic animals, and biodegrade into toxic by-products.

  • China in particular has long argued that it is too poor to afford the Western luxury of environmental awareness.
  • China ranks last among 15 nations in its income group (the fifth decile), behind Vietnam. If Colombia, the group's leader, can afford environmental concern, why can't China?
  • China fares slightly better in protecting its habitat but much worse in measures of industrial ills.

  • One conclusion to be drawn from the Yale-Columbia project is the need for better data, which requires funds.
  • Experiences like the recent biofuels surge, which is driving up food prices, show how treacherous even well-intentioned decisions about the environment can be when they're uninformed.
  • The same holds for consumers, who sometimes think paying somebody to plant a few trees will compensate for flying around the world in airplanes.
  • For such decisions, data are essential. If we're going to avoid squandering our natural resources, the quicker we begin to rely more on facts and less on assumptions, the better.
  • Some countries simply lie or make up the facts.
  • Today's Russian bureaucrats may still be fudging its environmental figures.
  • Among the worst offenders were Japan, South Korea, Brazil, the United States, Italy and Paraguay.
  • (While there are good comparative data on ozone, smog also includes nitrogen oxides, carbon monoxides and other components that are poorly tracked in most nations.) Among the best industrial countries were Malaysia, the United Kingdom and all of Eastern Europe (a legacy of the Soviet nuclear program).

      desert nations how trouble with water supplies. Israel looks better than other nations.
  • Saudi Arabia, Egypt and the United Arab Emirates, which have more severe water problems.
  • Brazil is another country whose high rank—34th—is deceptive.
  • Brazil is a vast land blessed with an abundance of water, which yields energy relatively cheaply with no carbon emissions
  • Brazil is now the world's fourth biggest emitter of carbon, mainly due to the felling of trees.
  • By contrast, Belgium and the Netherlands, which share much in terms of population and geography with their neighbors, suffer from neglect of the environment—particularly in protecting native habitats.

  • The conventional and traditional fuel sources are becoming more and more expensive to extract and their indiscriminate use in the past century has resulted in their depletion.

  • mankind would have perfected and commercialized alternate sources of fuel that will be eco- friendly and affordable too.
  • Its contents of 15% gasoline and 85% ethanol mean that it is at least better than using pure gasoline.
  • E 85, bio-diesel
  • Bio-diesel is one such alternate fuel source that is extracted from plants.
  • uch alternate fuel sources like E 85 score above gasoline, they still pollute and require a vast amount of corn to be grown
  • translates into availability of lesser land for growing food for people.
  • electric cars seem to be the best alternate fuel source that we have
  • conserve our natural fuel sources.
  • efficient because all of the electricity that they need can be generated at one central location.

  • A third of reef-building corals worldwide are threatened with extinction due to climate change and water pollution, according to the first global assessment on the marine creature by 39 scientists.
  • Destructive fishing and the degradation
  • "When corals die off, so do the other plants and animals that depend on coral reefs for food and shelter, and this can lead to the collapse of entire ecosystems," he added.
  • ...6 more annotations...
  • "We either reduce our CO2 emission now or many corals will be lost forever," warned Julia Marton-Lefevre, IUCN Director General.
  • According to the study, the Caribbean region has the highest number of highly threatened corals.
  • As they are home to over 25 percent of marine species -- including fish stocks -- loss of reefs could also impact coastal fishing communities.
  • depend on coral reefs for their livelihoods,
  • reef-building corals in particular were "most vulnerable to the effects of climate change".
  • Sea temperature rises bleach and weaken the algae that give the underwater sea life its vibrant color, and make it more susceptible to diseases.

  • used for scouring arsenic, bacteria and cloudiness out of rural drinking water
  • There, the residual water from boiling the flat, oval-shaped lobes of prickly pear for salads and other dishes was used to clear up cloudy water drawn from the river before use for cooking or drinking.
  • Mucilage is the clear, gooey, viscous liquid from within the cactus which helps to seal water inside the plant so it can survive desert-dry conditions.
  • ...3 more annotations...
  • She found that the mucilage binds to the dirt and causes the particles to coagulate, forming large enough clumps that they can settle out of the water.
  • The group's more recent research has shown that the mucilage can also form a complex with arsenic, a carcinogenic water contaminant that can occur naturally or from industrial or agricultural pollution.
  • "Sometimes we get 80 percent removal, and sometimes we get lower than 50 percent removal," Alcantar said. "We don't yet know exactly what it is; we haven't found what are the exact best conditions for the mucilage [to get the most arsenic removal]."
