biodiversity
Biodiversity is the measure of variety of the Earth's animal, plant and microbial species; of genetic differences within species and of the ecosystems that support those species. The term first came to public attention in 1992 at the Rio Earth Summit at which a convention for the preservation for the maintenance of biodiversity was signed by over 100 world leaders [excluding the USA as they feared it would undermine the patents and licences of US biotechnology companies] The maintenance of bi ...

Biodiversity
Extinction is defined as the end of existence of a group of organisms, caused by their inability to adapt to changing environmental conditions. Throughout the existence of our planet there have been large amounts of species extinctions. For instance, the dodo, a species of flightless pigeon formerly living on the island of Mauritius, became extinct in 1665. About 10,000 to 12,000 years ago, the most of the woolly mammoths and the last of the mastodons, both members of the elephant family, died. ... As all species living in the world's ecosystems, known as biodiversity, decreases, many of the resources in which we depend on as humans also deplete. ... Wordcount: 731 Pages: 3
Have we Entered the Third Event??
Have We Entered the Third Event? Climate change and sea level change followed by a catastrophic event, this is the lethal pattern that Peter Ward has observed taking place during to the first two mass extinctions in the earth's history. It is the fact that Ward has observed this pattern in the events of earth's history since the second event that has led him to form an alarming conclusion in his book "The End Of Evolution." He concludes that the earth is now in the midst of a third mass extin ... This climate change accompanied by a drastic drop in sea level drastically lowered the level of biodiversity on earth and created an unstable and fragile ecosystem just as in the first event. ... When we move into new territory and bring our crops, animals and bugs with us we are not considering our effect on the local ecosystem and on biodiversity. ... Many do not realize that life on Earth needs a minimum level of biodiversity to survive. ... We cannot build biodiversity like the Earth left to it's own devices can.

The conservation of our environment
The conservation of our environment has been a long standing debate between two extremes. On the one hand, some may argue for biodiversity, claiming that it has value for science amongst other things, on the other hand, there are those who may argue that putting a limit on the utilization of resour ... On the one hand, some may argue for biodiversity, claiming that it has value for science amongst other things, on the other hand, there are those who may argue that putting a limit on the utilization of resources of this earth is like saying that we are not good enough for nature. ... We must however realize that biodiversity is not merely saving wild life and creating protected areas, it is the protection of our own lives, the food we eat, the air we breath; biodiversity, as some would put it, is the very essence of our livelihood. ...

Reflections On Biodiversity
Since the time of Adam and Eve, mankind has changed. We no longer see, interact, or depend on nature the same way as we did thousands of years ago. Yet, we are still very much connected to the earth. Mankind continues to be engaged in nature"s challenge to survive. Our relationship with nature is stronger everyday as our understanding of the world expands. Our human lives are built around the inevitable laws and affects of nature. And so, while our perspectives and functions in nature have drama ... We are the only species that can observe and truly appreciate the biodiversity of life and the intricate and complex workings of other species and their roles in nature. ... Wordcount: 1013 Pages: 4
Environmental Protection Program
The collective action of humans - developing and paving over the landscape, clear-cutting forests, polluting rivers and streams, altering the atmosphere's protective ozone layer, and populating nearly every place imaginable - are bringing an end to the lives of creatures across the Earth.Ext ... The concept of biodiversity helps capture the magnitude of the problem. Biodiversity is the variety of, and interaction among, living organisms and the ecological complexes that they occur in, from the smallest habitat to the Earth as a whole. The concept also includes the genetic variability within these species, the raw material of both evolutionary adaptation and selective breeding by humans.In terms of biodiversity, extinction is more than the loss of individual species, it is the degradation of the ecological complexes that support all life on this planet. ...

Mag review
Usually, scientists studying biodiversity must climb mile high mountains, or trudge through the thickest forests in Africa, but Michael Hoggarth only has to take a dip in the local creek. Michael is involved in the study of fresh water mussels. When Michael puts on his hip waders and heads into the Killback Creek, in Ohio, he is on the lookout for one thing in particular, the purple catspaw. Only two populations of purple catspaw were known of previous to Mr. Hoggarth"s amazing discovery. W ... Usually, scientists studying biodiversity must climb mile high mountains, or trudge through the thickest forests in Africa, but Michael Hoggarth only has to take a dip in the local creek. ...

Deforesation
Imagine a place where there are more kinds of plants and animals than anyone has ever seen, a place filled with mysteries and marvels, surprising sights and strange sounds. Such a place really exists. It is called a tropical rainforest, and it is found in many countries around the world. Tropical rainforests are where you come across armies of ants, bird-eating spiders, giant earthworms, and squawking parrots, along with snakes gliding through the air. How exciting it would be to explore. ...

These consequences have negative effects on the climate, biodiversity, the atmosphere, and threatens the cultural and physical survival of indigenous peoples. ... Biodiversity is important because it contributes to resiliency. A world without biodiversity would be fragile and likely to amplify disturbance into catastrophe through the collapse of ecosystems that had lost keystone species. Thus, biodiversity reduction, combined with climate change, has the potential to spin out of control and to threaten the prosperity of global civilization.

Labor-intensive subsistence
I believe Labor-intensive subsistence agriculture is almost same as traditional agriculture, which produces only enough crops or livestock for a farm family¡s survival; therefore, they have low yields with intensive labors. This trends cause more lands are destructed and degrade by farming. On the other hand, labor-intensive subsistence agriculture produce less pollutants than industrialized agriculture because they reduce usage of fertilizer and pesticides.

Mass extinction
Mass extinction Extinction is a continual product of natural selection. since the dawn of competition spawned by the first meiosis event, natural selection has altered all life on earth, precariously engaging in life experiments some that work and some that don"t. Those experiments that do not work are those who have so far been extinct, and in fact 99%(Kiernan 1996:574) of all species that have ever engaged in the life battle have met their fate and are now extinct. why does this happen ...
