Earth Facts A-Z

Wild Earth

Wilderness or wildlands are natural places on our planet that have not been significantly modified by humans. These last, truly wild places that have not been developed with industry, roads, buildings and houses are critical for the survival of many plant and animal species. They also provide humans with educational and recreational opportunities, and are deeply valued for aesthetic, cultural, moral and spiritual reasons.

Some wildlands are protected, preserving natural areas for humans, animals, flora and fauna. Others are disapearing at alarming rates, and simply drawing lines around specific areas is not enough. All of our planet is intricately connected. What happens outside a specific wilderness area affects what happens inside it.

Many wildlife habitats have become fragmented due to human development. Without the protection of vast expanses of wildlands to meet the minimum requirements of the largest, most widely roaming members of the ecosystem, they may dwindle or vanish forever. The loss of any species effects the entire ecosystem.

Save the Earth

Our planet has a natural environment, known as ‘ecosystem’, which includes all humans, animals, plants, land and water. Human activities have caused much depletion and destruction of this ecosystem. Environmentalism advocates the preservation, restoration and/or improvement of this natural environment by controlling pollution and protecting plant and animal diversity. Environmentalists attempt to balance relations between humans and the various natural systems on which they depend to achieve sustainability. Earth advocates work to protect natural resources and ecosystems through education, activism and the political process.

Endangered Species

Well over 900 plants and animals are endangered, and hundreds more are threatened. Many of the reasons certain animals are disappearing forever are because of human activities. The mnemonic HIPPO represents the five major causes of declining wildlife biodiversity:

  • H - Habitat Loss
  • I - Invasive Species
  • P - Pollution and Pesticides
  • P - Population Growth (human) and the Pet Trade
  • O - Over-hunting and Over-collecting
Habitat Loss results from human activities and land development. Many animal species are in decline because their environment is no longer able to fulfill their basic requirements. All species require food, water, shelter, space and the ability to find a mate and have children. Some species require small habitats, while others need large areas to successfully survive.

Extinction Crisis

It's a dreadful reality. We are going through our sixth period of plant and animal mass extinction, the sixth to happen in the last 500 million years. The current wave is considered to be the worst series of species elimination since the dinosaurs disappeared 65 million years ago. Granted, extinction is a phenomenon that occurs naturally, however it normally happens at a rate of 1 to 5 species every year. But, as scientists estimate, we are currently losing species 1,000-10,000 times faster than that, which means that literally tens of species are vanishing from the face of the Earth every day. We could be looking at a frightening future. By this rate, almost one third to one-half of all species could become extinct by 2050.

The difference with past extinctions, which were caused by catastrophic natural phenomena like volcanic eruptions, asteroid strikes, and climate changes, is that the current crisis is caused almost entirely by humans. As many as 99% of the species at the threshold of extinction are there due to human activities.

Preserving & Protecting


Conservation is the protection of things found in nature, including species, their habitats and ecosystems. It encourages the sensible use of the planet’s natural resources so they do not go extinct, and promotes keeping the environment clean and healthy. The rapid decline of established biological systems around the world means that conservation biology is often referred to as a "Discipline With a Deadline" - we must act before it is too late. Preservationists advocate for giving areas of nature and species a protected existence without interference from the humans. In this regard, conservationists differ from preservationists, as conservation engages society to seeks solutions for both people and ecosystems. Environmentalism advocates the preservation, restoration and/or improvement of the natural environment, and seeks to control pollution and protect plant and animal diversity.Animal advocates believe humans have a moral responsibility to treat animals with respect, and that the interests of humans and animals should be considered equally.
