 Coastal Erosion
Every time there is a bad coastal storm in Australia, we see the results on television, with homes collapsing or the coastal edges creeping closer to the fences that enclose them. Much coastal land is quite flat, so will be most affected by rising sea levels. Homes should certainly not be built right on the coastline in any country. |

 Ocean Suffers The atlas, which was unveiled here Thursday at the annual meeting of the American Association for the Advancement of Science, was drawn up by combining impact data for 17 different activities, ranging from fishing and commercial shipping to pollution and climate change.
Coral reefs, continental shelves and the deep ocean were the hardest-hit ecosystems, the international team behind the research reported. The biggest human impact was seen in the North Sea, the South and East China Seas, the Caribbean and North America's East Coast. The least-affected areas were largely near the poles. |

 Solar Panels
The history of photovoltaic energy (aka. solar cells) started way back in 1876. William Grylls Adams along with a student of his, Richard Day, discovered that when selenium was exposed to light, it produced electricity. An electricity expert, Werner von Siemens, stated that the discovery was "scientifically of the most far-reaching importance". The selenium cells were not efficient, but it was proved that light, without heat or moving parts, could be converted into electricity.
In 1953, Calvin Fuller, Gerald Pearson, and Daryl Chapin, discovered the silicon solar cell. This cell actually produced enough electricity and was efficient enough to run small electrical devices. The New York Times stated that this discovery was "the beginning of a new era, leading eventually to the realization of harnessing the almost limitless energy of the sun for the uses of civilization." |

 Solar Panels
While the use of solar energy has been used for millennia, it’s potential has only been recognized within the past few decades, when it played an essential part in the success of early commercial satellites. After the Solar energy collected, it is most often stored as heat in the thermal mass of buildings, however batteries, water tanks, and other storage facilities can be used to store energy in thermal and chemical forms.
Solar energy provides an energy efficient and environmentally friendly power source and it has satisfied the demands of activists for an eco-friendly world. Solar energy has also become an attractive solution to global warming. |

 Killing Whales
Nobutaka
Machimura, Japan's top government spokesman, confirmed that the
Japanese fleet, now en route to the southern ocean whale sanctuary,
would avoid killing humpbacks, a protected species since 1966.
"Japan has decided not to catch humpback whales for one year
or two, but there will be no change in our stance on research
whaling," he told reporters. "Japan's relations with Australia could
improve, but it depends on how it will see our decisionArticle
continues
Japan's original intention to kill 50 humpbacks, considered
the most majestic and athletic of all whales, drew a furious response
from Australia, where an estimated 1.5 million tourists take part in
whale-watching trips every year. |
