The Importance of Biodiversity Here's the problem with the loss of biodiversity: The Earth functions like an incredibly complex machine, and there don't appear to be any unnecessary parts. Each species -- from the lowliest microbe to humans -- plays a part in keeping the planet running smoothly.	How does Biodiversity loss affect... How does Biodiversity loss affect me and everyone else? - Biological diversity is the resource upon which families, communities, nations and future generations depend. It is the link between all organisms on earth, binding each into an interdependant ecosystem, in which all species have their role. It is the web of life.
Scientists discover gorgeous ... For the past four years, scientists have been under the sea, collecting tiny creatures from all the world's oceans and analyzing them. This expedition, on board the schooner TARA, set out to map the biodiversity of a wide range of planktonic organisms. They collected 35,000 samples and observed the organisms, exploring their interactions and how they are affected by their environment, primarily the temperature and acidity of the oceans.

What does biodiversity mean for ... What does biodiversity mean for human health? People depend on biodiversity in their daily lives, in ways that are not always apparent or appreciated. Human health ultimately depends upon ecosystem products and services (such as availability of fresh water, food and fuel sources) which are requisite for good human health and productive livelihoods. Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs.	Thawing Permafrost Permafrost refers to a layer of soil or rock that is frozen all year round. Permafrost is found throughout much of Alaska, parts of Canada, and other countries in the far north.

When Sea Levels Attack! When Sea Levels Attack! - Information is Beautiful.	Sea Level - Australian Government Sea level rise is caused by two processes: thermal expansion (ocean water expanding as it heats up) and additional water flows into the oceans from ice that melts on land. Both these processes are currently being observed.	Rising Seas Interactive Rising Seas Interactive National Geographic - If all the ice melted.
How Ocean Currents Work Deep Ocean Currents (Global Conveyor Belt) - Invisible to us terrestrial creatures, an underwater current circles the globe with a force 16 times as strong as all the world's rivers combined.	The Ocean in Motion The ocean water is in motion because of differences in temperature and saltiness. Water that is warmed at the sea surface near the equator moves toward the chilly poles. Cold, salty currents flow into the deepest parts of the sea.	Ocean Currents and Marine Life Currents are powerful physical forces in the seas. They move water and heat around the globe, and help determine the chemical make-up of the water column. Currents also are a major factor in ocean ecosystems. Two types of current motion, upwelling and downwelling, strongly influence the distribution and abundance of marine life.
Warming Lakes Warming Lakes: Effects of Climate Change Seen on Lake Tahoe - Lake Tahoe is one of hundreds of lakes around the world in the midst of a warming trend.
