  • Vast greenhouses that use sea water for crop cultivation could be combined with solar power plants to provide food, fresh water and clean energy in deserts, under an ambitious proposal from a team of architects and engineers. The Sahara Forest Project, which is already running demonstration plants in Tenerife, Oman and the United Arab Emirates, envisages huge greenhouses with concentrated solar power (CSP), a technology that uses mirrors to focus the sun's rays, creating steam to drive turbines to generate electricity.

    "A land mine is a target (person or vehicle) triggered explosive weapon . Their non-explosive predecessors (caltrops, stakes and spikes) have been used on the battlefield since ancient times. Landmines were designed to be used to deter, channel, delay and kill an enemy. They have been used in various formats, for centuries and have featured in all major conflicts. Land mines are force multipliers , meaning that they may increase the efficiency of a force without requiring more personnel. The name originates from the practice of mining , where tunnels were dug under enemy fortifications or forces. These tunnels ("mines") were first collapsed to destroy fortifications above, and later filled with explosives and detonated. Land mines generally refer to devices specifically manufactured for this purpose, as distinguished from improvised explosive devices ("IEDs"). The use of land mines is controversial because they are indiscriminate weapons, harming soldier and civilian alike. They remain dangerous after the conflict in which they were deployed has ended, killing and injuring civilians and rendering land impassable and unusable for decades. To make matters worse, many factions have not kept accurate records (or any at all) of the exact locations of their minefields, making removal efforts painstakingly slow. These facts pose serious difficulties in many developing nations where the presence of mines hampers resettlement, agriculture, and tourism. The International Campaign to Ban Landmines campaigned successfully to prohibit their use, culminating in the 1997 Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on their Destruction, known informally as the Ottawa Treaty . As of 2007, a total of 158 nations have agreed to the treaty. Thirty-seven countries have not agreed to the ban, including China , India , Israel , Pakistan

  • The Champions of the Animal KingdomPeople are good at a lot of things, but if animals could enter the Olympics as one team they would probably win almost all the medals! Animals can outrun, outswim, and outjump all humans. Young cheetahs learn to hunt by watching their mother. Later, they start taking part in the hunt. Cheetahs are the fastest land animal and can reach speeds of 113kph in short bursts. ©G.Ellis/GLOBIO.org Fastest Mammal on Land Cheetahs can run up to 113 kph. Fastest Mammal in Water Dall porpoises can swim up to 56 kph. Fastest Flying Bird Peregrine falcons can dive toward the ground at more than 320 kph. Fastest Flightless Bird North African ostriches are the fastest birds on land. They can run at speeds up to 72 kph. They are also the biggest bird. They can weigh 155 kg. Fastest Fish Sailfish can swim up to 109 kph. Loudest Animal The blue whale’s low-frequency pulses are as loud as 188 decibels. This is louder than a jet engine. A blue whale’s call can be detected more than 805 km away. On land, the loudest animals are howler monkeys. Their howls can be heard 4.8 km away.

  • Arctic terns migrate to and from the Antarctic - about 35,405 km round trip - each year. Among mammals, gray whales and northern elephant seals are the migration champions. They travel up to 20,900 km round trip each year. Deadliest Animal Female Anopheles mosquitoes, which carry and transmit malaria, play a role in the deaths of more than a million people each year. Most Venomous Animal A single sea wasp (a kind of jellyfish with 60 tentacles, each 4 m long) has enough venom to kill 60 adult humans. Strongest Animal The rhinoceros beetle can lift 850 times its own weight

  • Longest Gestation Asian elephants are born after a gestation period of 19 to 22 months. Largest Mammal Blue whales are the largest mammals of all time and the largest living animal. Females grow to a length of about 27 m. They may weigh well over 100 metric tons. The heaviest blue whale weighed more than 190 metric tons. The longest ever measured was more than 33 m. African elephant bulls are the heaviest land animal. Large males may weigh as much as 5,895kg. Despite their power and size, elephants are vegetarians, or herbivores. ©G.Ellis/GLOBIO.org Largest Living Animal on Land African elephants are the heaviest land animal. They are also the second tallest land animal. Large bulls (males) weigh more than 5,895 kg and are 3.5 m tall at the shoulder. Giraffes, which can grow to a height of 5 m, are the tallest land animals. Large males weigh more than 1,800 kg. Smallest Vertebrate Australia's stout infantfish, slightly smaller than the better-known dwarf goby, is less than 1 cm long. Smallest Bird Adult bee hummingbirds, found in Cuba, weigh about 2 g. Smallest Mammal Adult bumblebee bats, which live in Thailand, weigh about 2 g. Longest Lifespan In the 1770s, British explorer Captain James Cook presented a Madagascar radiated tortoise to the royal family of Tonga. The tortoise lived until 1965. It was at least 188 years old when it died! Several Galápagos tortoises h

FastFacts, Respecting Our Wood Resource - 0 views

  • Respecting and ExtendingOur Wood Resource Today's near-zero-waste sawmills use computers and sophisticated equipment such as laser-guided saws to get the most lumber out of each log. In fact, today's mill recover about twice as much lumber from each log as did mills at the turn of the century. The wood fiber that is not usable as lumber is recovered and processed into other valuable products. These "by-products" of lumber manufacturing can become particleboard , oriented strandboard paneling, or other engineered-wood products. Byproducts are also used to fuel cogeneration plants which produce electricity for the sawmills. And wood fiber also is used to make such products as plastic filler, shoe polish, toothpaste, varnish, foam rubber, and much more!
