These are some of the facts that all residents of Planet Earth should know to appreciate their own habitat.
Melting of sea ice, formed over water from freezing salt water, will not raise sea levels. Compressed snow ice sheets and glaciers formed over land as they melt do raise sea levels.
Coral reefs are the Earth’s most biologically diverse marine ecosystems. Coral reefs are home to 25 percent of all known fish species but only take up .025 percent of the marine environment. They protect shorelines providing about $375 billion yearly in coastal protection, food, tourism revenue, and new medications.
Tropical rainforests are the most biologically diverse ecosystems on the Earth’s land. They are being destroyed by global timber harvesting and local subsistence farming. Over 100 drug companies and the U.S. government fund studies to find more medicinal plants for drugs like quinine, steroids, cancer drugs and muscle relaxants.
Old growth forests, primary forests, ancient forests, virgin forests, primeval forests, ancient woodlands are all names for minimally disturbed forests of significant age. They are home to a wide plant and animal variety and are threatened by lightning, erosion but mostly logging by man. It takes at least 300 years to replace them even when replacement trees are planted.
Although 70 percent of the Earth’s surface is covered by water, only 2.7 percent is fresh water and about two-thirds of that is frozen. Less than one percent can be used by humans. The Earth’s population at six billion uses almost 30 percent of that water supply now even though only 1 in 5 people have safe drinking water. In 2025 water usage is estimated to be at 70 percent. Nations and corporations are fighting over water supplies.
Tides are caused by the earth’s rotation and the sun and moon’s gravity pulls. Tides move water and clean out wastes, help in navigation so ships can enter and exit harbors, and refill tide-pool habitats. The Bay of Fundy in Canada between Nova Scotia and New Brunswick reaches the highest tide at 52 feet.
Climatologists have developed a baseline global average temperature of 60°F after dividing the Earth into zones ranging through a freezing Arctic, parched deserts and very hot tropics. Scientists have calculated the mean global temperature increase since the late 1800s has been about 0.5 to 1°F.
Humans who have preceded this generation have taught that man must do as little harm as possible to let nature heal.
- Aborigines say we borrow the Earth from our children, not inherit it from our parents.
- Pacific Island cultures started marine resource management with entry limits, size limits, closed seasons and areas, gear restrictions and spawning protection that we should follow today.
- For centuries, Feng Shui promoted environment sensitivity to rocks, trees, rivers and landforms.
- Native American Indians teach their young to pass through forests without leaving footprints.
All nations on Earth must help nature remain in balance and promote as little destruction as possible. Watch the attached video for some outstanding photos and interesting facts about Earth.
