Environmental Protection
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. Extinction of biological species is not necessarily a phenomenon initiated by human activity, some argue. Although the specific role of extinction in the process of evolution is still being researched ... 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. ... 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. ... Undisturbed ecosystems, with their natural level of biodiversity - regulate the flow of energy and the cycling of nutrients, which all life depends on. ... Plans to preserve b...

Labor-Intensive Subsistence and Traditional Agriculture
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. The biggest advantages of energy-i ... It is also an important way to protect biodiversity by saving large areas of forests, grassland, and wetlands from being used to grow food. ...

The Great Challenge of 21st Century
One of the biggest issues facing governments around the world is ensuring there is enough food for every person on this planet. When compared to the many advances made in almost every field, the production and distribution of food in the third world and developing nations has remained very poor. Technology has made now it possible to clone and mutate existing plants so that they can be relocated to almost any area of the world to be harvested. With population statistics showing "an adding on ave ... (Juma, 1989: 23) The conservation of agricultural biodiversity is crucial in terms of keeping used grounds fertile and productive. ...

The World Conservation Strategy
INTRODUCTION A major challenge for mankind is an informed respose to unprecedented urban growth and the intelligent mangement of urban settlements. The 20th century began with perhaps a dozen cities of 1 million resisdents; it will end with several hundred cities of that size, including about 30 urban areas with population exceeding an arbitrary threshold of 8 million. Most of today's cities provide neither equilibrium with the enviornment nor stability for its citizens. Ever since the the c ... A sustainable city is one which, recognizes that growth occurs within some limits and is ultimately limited by the carrying capacity of the environment, values biodiversity, uses renewable and reliable sources of energy, and does not compromises the sustainability of future generations by its activities. ...

Endangered Species
White, wild, and wonderful Before European settlement, as many as 150,000 trumpeter swans populated the Eastern United States. By the end of the 19th century, they were all gone, victims of pioneer settlers who wanted their meat, or of hatters, who wanted their feathers. (Hatters played a surprisingly large role in the conservation movement: their use of feathers from the great blue heron and the bald eagle helped spark the formation of the Audubon Society and the passage of laws protecting mi ...

Tropical Rain Forest Biome
Tropical Rain Forest Biome The tropical rain forest biome is at least 65 million years old. They are among the Earth"s oldest forest communities.

There are more varieties of species of plants and animals in tropical rain forests, than in all the worlds ecosystems combined. Around 70 percent of all plant s ...

An Alarming Portrait of the Nuclear Power in the World
Unfortunately, even if someone could wave a magic wand that causes all of the nuclear weapons on earth to disappear, many believe that due to the depletion of natural resources, the earth would still be in danger of catastrophe, and humankind in danger of extinction. Jonathan Schell's book "Fate of the Earth" is an alarming portrait of the nuclear power in the world. Since the end of World War II, nuclear arms have kept the world's population in a state of constant concern that "something" c ...

Selective Breeding
For thousands of years we have tried to select plants for improved yield, growth or food characteristics. In the past, this has been done by selective breeding, selecting the plants with desired characteristics and crossing it with another plant with other desired characteristics. As a result a new variety of the plant formed at a much faster rate that would occur in the wild. The problem with this was when plants were crossed with ancestral varieties, the embryos do not survive very well. Anoth ... Potential loss of biodiversity. ... Wordcount: 950 Pages: 4
What is the Sixth Extinction?
So, what is the Sixth Extinction? When is it coming and what is its cause? It is happening now, and we, the human race are its cause explains Richard Leakey. This phenomenon Leakey argues, is easily comparable with the big five biological crisis' of geological history, except this one is not being caused by global temperature change, regression of sea level, or asteroid impact. It is being caused by one of Earth's inhabitants. According to Leakey, humanity is poised to become the greatest c ...

The Cane Toad
Australia's most bothersome invader species may be the Cane toads (Bufo marinus), warty amphibians that tend to devour everything they can fit in their mouths, including lizards, mice, dog food, even other cane toads, and because they are poisonous, they have no natural predators (Stroh 2002). This amphibian, which can grow to roughly one-foot in length and weigh as much as ten pounds, is one of the many human-introduced species that is currently ravaging the ecosystem in Australia (Young 2000) ... Cane toads are considered a major threat to biodiversity, not only because they out-compete native species for food and consume others, but their skin toxins kill carnivorous predators that mistake them for local amphibians (Lunter 2004). ...
