African Lions, African Lion Pictures, African Lion Facts, African Cats. Lions are the only cats that live in groups, which are called prides. Prides are family units that may include up to three males, a dozen or so females, and their young. All of a pride's lionesses are related, and female cubs typically stay with the group as they age. Young males eventually leave and establish their own prides by taking over a group headed by another male. Only male lions boast manes, the impressive fringe of long hair that encircles their heads. Males defend the pride's territory, which may include some 100 square miles (259 square kilometers) of grasslands, scrub, or open woodlands.
These intimidating animals mark the area with urine, roar menacingly to warn intruders, and chase off animals that encroach on their turf. Female lions are the pride's primary hunters. After the hunt, the group effort often degenerates to squabbling over the sharing of the kill, with cubs at the bottom of the pecking order. Major Lion Die-Offs Linked to Climate Change. June 25, 2008 Droughts and downpours exacerbated by climate change allowed two diseases to converge and wipe out large numbers of African lions in 1994 and 2001, according to a new study. Lions regularly survive outbreaks of canine distemper virus (CDV) and infestations by a tick-borne blood parasite called Babesia.
But both normally occur in isolation. In 1994 and 2001, however, a "perfect storm" of extreme drought followed by heavy seasonal rains set up the conditions for the two diseases to converge, the study said. The effect was lethal: The synchronized infections wiped out about a third of the Serengeti lion population in 1994. The nearby Ngorongoro Crater lion population experienced similar losses in 2001. (Read a National Geographic magazine online extra about Serengeti and other lions.) "It was already well known that die offs can be triggered by droughts and floods," Craig Packer, an ecologist at the University of Minnesota in St. "Lethal One-Two Punch"
Stochastic events, disease and climate change - ALERT | African Lion & Environmental Research Trust. How do trees and forests relate to climate change? | Environment. Deforestation, and especially the destruction of rainforests, is a hugely significant contributor to climate change. Scientists estimate that forest loss and other changes to the use of land account for around 23% of current man-made CO2 emissions – which equates to 17% of the 100-year warming impact of all current greenhouse-gas emissions. As children are taught at school, trees and other plants absorb CO2 from the air as they grow. Using energy from the sun, they turn the carbon captured from the CO2 molecules into building blocks for their trunks, branches and foliage.
This is all part of the carbon cycle. A mature forest doesn't necessarily absorb much more CO2 that it releases, however, because when each tree dies and either rots down or is burned, much of its stored carbon is released once again. Of course, the same process also works in reverse. The ultimate climate change FAQ Related questions• Is the world really getting warmer?
Climate change: the forest connection | SinksWatch. Most people are now aware that the world’s hunger for energy from fossil fuel is leading to catastrophic climate change. What is also becoming increasingly clear is the effect that forests have on the climate and the climate has on forests - and how changes in one system will affect the other. Forests’ effect on the climate Forests play an important role in regulating the earth's temperature and weather patterns by storing large quantities of carbon and water. This regulatory function has a profound effect on both the local and the global climate. Locally, trees provide shade, which in turn lowers summer temperatures and prevents the soil from drying out, they reduce heat loss from the ground in winter and reduce storm damage by providing shelter from wind. Globally, forests regulate the global carbon cycle, having a profound effect on the climate. The climate’s effect on forests What can be done?

Climate Impacts on Forests Key Points Climate change will likely alter the frequency and intensity of forest disturbances, including wildfires, storms, insect outbreaks, and the occurrence of invasive species. The productivity of forests could be affected by changes in temperature, precipitation and the amount of carbon dioxide in the air. Climate change will likely worsen the problems already faced by forests from land development and air pollution. In the United States, forests occupy approximately 751 million acres, about one third of the country's total land area. [1] America's forests provide many benefits and services to society, including clean water, recreation, wildlife habitat, carbon storage, and a variety of forest products.
Climate changes directly and indirectly affect the growth and productivity of forests: directly due to changes in atmospheric carbon dioxide and climate and indirectly through complex interactions in forest ecosystems.

The Daily Show: Extended Interview: Malala Yousafzai. Because I am a Girl - Girls’ education. Every girl has a right to an education, but close to 62 million girls around the world are not in school, and even more struggle to remain where they belong – in the classroom. Every day, girls are taken out of school, married far too young, and subjected to violence in school. And yet, it’s proven that with an education, girls can lift themselves – and everyone around them – out of poverty.
The facts on education for girls For every extra year a girl stays in school, her income can increase by 15 to 25%There is a 20% increase in child survival when household income is in a mother’s handsIf 10% more girls attend school, a country’s GDP increases by an average of 3%When a girl receives more education, she is 6X less likely to be married as a child and will have 2.2 fewer, yet healthier children who are more likely to go to school themselvesEach extra year of a mother’s schooling cuts infant mortality by between 5 and 10% The facts are clear. So, what’s keeping girls from school? Malala Yousafzai, Girl Shot by Taliban, Was Drawn to Politics by Dad. Correction Appended: Oct. 17, 2012 Malala Yousafzai is only 14 years old, but she has always come off as preternaturally mature, able — even at 11 — to talk about serious issues like education and terrorism and her native Pakistan’s troubled relations with India. The attempt on her life and the ensuing medical emergency have made her a hero to a greater audience.
But in the patriarchal and conservative Muslim world she grew up in, a pioneer like Malala would not have been possible without another hero: her father. The saga “is a story about a father and a daughter, more than a story about a girl,” says Adam Ellick, a journalist and documentary filmmaker who covered the 2009 shutdown of the schools in the Swat Valley because of Taliban threats that led to the displacement of the Yousafzai family and thousands of others. (MORE: How Malala Yousafzai May Affect Pakistan’s Culture Wars) “I can’t imagine being his child and not fully taking on everything he says,” says Ellick.

Alex Lin was a boy who was just reading the newspaper one day. He read an article about something called e-waste. He learned that it is the waste generated as people upgrade electronic devices. When people are done with things like computers, phones, mp3 players, etc. and throw them away, that’s e-waste. He also learned that e-waste is dangerous to the environment. To help stop e-waste, Alex got help from his community service group, the Westerly Innovations Network (WIN).

Christmas gifts from past years meet a sad end at Absolute Green Electronics Recycling in California. Computers are dismantled. Their parts get sorted into cardboard bins. One bin holds nothing but hard drives. Another holds AC adapters. Bins stretch in rows across a huge warehouse. There are bins for cellphones, camcorders, digital cameras, cables and network switches. Stacked-up printers form a miniature mountain. “There are different grades of boards,” said owner and president Victor Kianipay, stepping past dust-covered TVs to poke into apple boxes filled with circuit boards.
E-Waste A Global Problem This is electronic waste, or e-waste. Within five years, the annual figure may reach 65 million tons, the group estimates. A lot of companies send electronic waste to developing countries. “You see all these thousands — literally thousands — of women and young kids whose job is to cook circuit boards,” said Jim Puckett.
