1. Essay On Endangered Plants
Biodiversity
Imagine this: you step outside and feel the barren, rough, red Earth beneath your feet. There's not a
single plant in sight–no rustling of the leaves, no mighty towering trees to block the severe winds,
and the scorching heat of the sun searing upon your face because there's no shade. And when you
take a whiff of air, you feel nothing filling up the space inside your lungs, liberating your body's
activities. What's wrong with this picture? It's not possible, of course. Even though plants aren't the
building blocks of life, they're pretty close and without them, most of life wouldn't exist–YOU
wouldn't exist. In my research, I will go in–depth about biodiversity–which defines as a quantity of
the relative diversity among...show more content...
Based upon the same experiments and samples taken, it was concluded that the atmospheric nitrogen
pollution was caused by the burning of fossil fuels and rigorous agriculture (Ananthaswamy, 2004).
According to the 2004 release of the Threatened and Endangered Species System (TESS)
information, there are 599 endangered plants and 147 threatened plants in the US alone (TESS,
2004). These listings rely on a very stern legal system. Whether they can be labeled "rare",
"threatened," or "endangered", it is determined by the measure of endangerment the species sustain.
An "endangered" type is one that is in jeopardy of extinction throughout all or a major fraction of its
range. A "threatened" species is one that is likely to become in danger of extinction in the future
(UFWS, 2004).
Ways for prevention of plant dissolution/ rewards
Here in DeKalb County, we have several different threatened plant species. They are: Bay–star Vine,
Flatrock Onion, Granite Rock Stonecrop, Indian Olive, Piedmont Barren Strawberry, and the Pool
Sprite Snorkelwort. We have one endangered plant: it is the Black–spored Quillwort (UFWS, 2004).
There are over 542 discrete approved ecosystem recovery plans. Some plans cover more than one
species while a few have different plans covering various parts of their ranges (TESS, 2004). One
organization is the Botanic Gardens Conservation International. It has just recently been added as a
participant of the bigger

2. Essay on Biodiversity
Biodiversity
INTRODUCTION Franck and Brownstone define biological diversity as 'the variety and variability
of living organisms and the biological communities in which they live' (36). Decades of progress in
both the scientific and political arenas have advanced environmental legislation to protect
biodiversity at not only the ecosystem level, but for specific species and genetic material as well.
Research has shown the importance of every organism and their role in the global ecosystem, and
legislation has gradually matured to protect not only species which may become endangered, but the
habitats they need to survive as well. Growing consciousness surrounding environmental issues has
enabled these protections to be...show more content...
Simultaneously, thousands of other species across the globe face the same threat: extinction.
Biodiversity is an essential part of our world, our global ecosystem. As Planet Earth?s resources
diminish and its creatures vanish, those who recognize the need to preserve what is disappearing
look to international politics to accomplish what individuals cannot. The most important instrument
for implementation of international policy has been the Convention On International Trade in
Endangered Species of Wild Fauna and Flora (CITES), which went into effect in 1975.
The plight of the rhinoceros is not unlike the all–too–familiar danger that the elephant faces. Illegal
trade is greatly responsible for the endangerment of the species. Valued for their ivory horns, over
90% of the five rhino species have disappeared, while the rest continue to dwindle. The worth of
one rhinoceros horn is $44,000, and the demand remains high in the countries of China, Taiwan,
South Korea and in the Middle East. In East Asia, the horns are regarded as powerful medicinal
tools, known to cure everything from nosebleeds to food poisoning. In a powdered from, the horn is
thought to be a powerful aphrodisiac. Similarly, the animals? genitalia are also considered extremely
valuable.
Existing rhino populations continue to decline. In East Africa, the Black Rhinoceros

Biodiversity
a.Biodiversity– is the degree of variation of life. It is a measure of the variety of organisms present
in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation
(number of species) within an area, biome, or planet. Terrestrial biodiversity tends to be highest near
the equator, which seems to be the result of the warm climate and high primary productivity.
Biodiversity is not distributed evenly on Earth. It is the richest in the tropics. Marine biodiversity
tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and
in the mid–latitudinal band in all oceans. There are latitudinal gradients in species diversity.
Biodiversity generally tends...show more content...
As ecosystems are defined by the network of interactions among organisms, and between organisms
and their environment, they can be of any size but usually encompass specific, limited spaces. f.
species diversity– is the number of different species that are represented in a given community (a
dataset). The effective number of species refers to the number of equally abundant species needed
to obtain the same mean proportional species abundance as that observed in the dataset of interest
(where all species may not be equally abundant). Species diversity consists of two components:
species richness and species evenness. Species richness is a simple count of species, whereas
species evenness quantifies how equal the abundances of the species are. g. species richness–is the
number of different species represented in an ecological community, landscape or region. Species
richness is simply a count of species, and it does not take into account the abundances of the species
or their relative abundance distributions.

4. Biodiversity And Biodiversity
The current climate change is projected to have a significant influence over biodiversity. The
changes create risk to almost all the species on land to extinct by 2050. Due to earth's rapid
warming that is now faster than at any time in the past 10,000 years, the species survival is likely
to be at the fullest risk. The rapid heating temperature on earth almost always caused danger to
plants, animals, places and even people's livelihoods. It also damages the ecosystem, including
coral reefs, whole loss of unique forms of life that will create a complete disaster on earth. These
changes force the species to adapt to new climate patterns, if species can not evolve to live in a
certain ranges of temperature, or when it actually lives dependent to a certain temperature range,
then its existence is endangered. With the more intense rising of sea level and warmer ocean, the
prolonged period of a shortage of water resulted threaten crops, wildlife and storage of fresh water.
Various studies reveal that species usually move to higher elevations and latitudes in response to
climate change. The local extinction also record the loss of population at the warm edge of species
ranges that located in the lower elevations and latitudes. The data particularly show that roughly
half of the 976 species surveyed has extinct. Loss of species is normally happen in tropical region
across the climatic zones, habitats and group of organism. The species mostly are Earth's species

"BIODIVERSITY"
Biodiversity, as defined by E.O. Wilson, "is meant to be all inclusive– it's the genetic based
variation of living organisms at all levels, from the variety of genes in populations of single species,
through species, on up to the array of natural ecosystems." This includes plants, animals,
insects, fungi, bacteria, and all microorganisms. All of these things create what is known as a web.
These things interact with each other in some way there for they depend on one another throughout
their lifetime. There are many separate ways in which we can study biodiversity. These ways
include, genetic, species, community, ecosystem, and taxonomic diversity. Biodiversity can be best

In the video, during the drought, the side of the field with a more diverse environment held stern as
the other wilted away.
Areas that are very diverse are very important to humans as well. They provide a wide arrange of
pharmaceuticals such as aspirin and penicillin. "Some
40 percent of U.S. prescriptions are for pharmaceuticals derived from wild plants, animals and
microorganisms.(E.O. Wilson)" They also provide fruit, oils, beverages, drugs (including
illegal narcotics), fuel, and much more. Humans also benefit from biodiversity from what E.O.
Wilson calls "biophillia," which is the natural affiliation humans have for natural
environments.(E.O. Wilson)
Old growth forests play a dentrimental role in biodiversity preservation.
It's most important feature is biodiversity. Old growth forests provide us with many of the things
that we as humans take for granted, for example, breathable air pure water, and pest control through
birds, bats, and insects.
In the Eastern U.S., most of the old growth occurs in small isolated areas.
Scientist have come to the conclusion that even if these matured areas cover a substantial portion of
landscape, it will not provide long term diversity for many species that live in such a
community.(How much old growth..?)
Many environmentalists are increasingly concerned with this biodiversity
