Project Squirrel is calling all citizen scientists to count the number of squirrels in their neighborhoods and report their findings. The factory no longer represented even the realm of necessity — environmental determinants having rendered the factory system of industrial production ecologically and vis a vis economically redundant.

These are not the only corporations responsible for destroying tropical rainforests, unfortunately there are hundreds of others. Supporting and donating to organizations that save rainforest acreage are other ways to help save the forests , e.

Young orang-utans are delicate animals and are susceptible to the same diseases as human beings. Captured animals are generally kept under unhygienic conditions and forced to exist on an unnatural diet, with the result that most of them die from malnutrition or disease. Other algae absorb nutrients from their surroundings. Although most algae are water plants, green and blue- green algae do appear in the rain forest where they encrust the leaves of trees.

Unlike algae, fungi cannot make their own food by photosynthesis. Some fungi, like molds and mushrooms, obtain nutrients from dead or decaying organic matter material derived from living organisms.

They assist in the decomposition breaking down of this matter and in releasing the nutrients needed by plants back into the soil. Other fungi are parasites. Fungi reproduce by means of spores, which are usually single cells that have the ability to grow into a new organism. Fungi prefer moist, dim environments, and they thrive on the shadowy forest floor.

Some, like the marasmius, grow directly on the litter of plant matter, while others protrude from the trunks of trees. Another type of fungi, the mycorrhizae, live in the soil and surround the roots of most rain forest trees. Lichens are actually combinations of algae and fungi that live in cooperation. Fungi surround algae cells, and the algae obtain food for themselves and the fungi by means of photosynthesis. It is not known if fungi aid algal organisms, but it is believed that fungi may provide moisture for the algae.

Lichens often appear on rocks and other bare woodland surfaces. Some grow on the leaves of lowland trees, while others favor the cooler cloud forests and dangle from the limbs of trees. Lichens are common in all types of forests and seem able to survive most climatic conditions. Most green plants need several basic things to grow: sunlight, air, water, warmth, and nutrients. In the rain forest, water and warmth are abundant. However, nutrients such as nitrogen, phosphorus, and potassium, which are typically obtained from the soil, may not be in large supply.

Light can be scarce because the thick forest canopy obscures the forest floor, and may block sunlight. The lack of seasons means that the canopy is in full leaf all year long. For this reason, most rain forest plants grow in the canopy of the forest. Those that do grow on the ground often have very large leaves that provide more surface area to be exposed to the scarce amount of light. Common rain forest plants include rattans, pitcher plants, ferns, African violets, nasturtiums, Spanish mosses, orchids, lianas, urn plants, hibiscus shrubs, and bamboo.

Liana Lianas are climbers found in rain forests throughout the world. Their roots can be large and tough, but they do not develop a thick trunk. Instead, they depend entirely on trees for support. Once they reach the canopy, they drape themselves among the branches and develop leaves, branches, flowers, and fruits. A common liana is the strangler fig, which begins as an epiphyte that sends long roots down to the ground.

These roots grow branches that. In the rain forests of Central and South America grows the cocoa, or cacao, tree. The seeds of this delightful tree produce chocolate. Initially, the roasted seeds were used by the Aztecs to make a hot drink flavored with vanilla and spices. Over the next years, the use of cocoa spread to other parts of Europe and, by , solid chocolate had been developed in France. Around , the English improved hot chocolate by adding milk, and by , manufacturing processes made sweet eating-chocolate possible.

By , its popularity had spread throughout the world. Cocoa trees are raised on farms in Central and South America and portions of western Africa. In , 1,, tons 1,, metric tons of cocoa seeds were produced, and 20 percent of all the exports went to the United States. However, Americans consume only about 10 pounds 4. The largest consumers are the Swiss, who eat 21 pounds 9.

Although the names are sometimes confused, the cocoa tree is not the source of the drug cocaine. Cocaine comes from the coca shrub, an unrelated plant. Eventually, the host dies and decays, leaving a hollow ring of stranglers. Urn plant Urn plants are epiphytes found in Central and South America that belong to the pineapple family. Little hairs on the leaf surface absorb the water and dissolved minerals.

Urn plants provide homes for many aquatic water insects and even frogs. Hibiscus Hibiscus shrubs grow on the ground around the edges of the forest where they can obtain light. In Africa, they quickly attain heights of up to 7 feet 2 meters. Their large, colorful flowers are bell shaped and may be scarlet, pink, yellow, or white.


Bamboo Bamboo is a woody grass that can grow as tall as a tree. Dense forests of bamboo are found in Asia and Central Africa where plants may reach feet 40 meters in height. Bamboo tends to grow in thick, tightly packed clumps. Flowering occurs several years later, after which the plant dies.

There are species of bamboo. Its uses vary from food to instrument to paper. It is always growing season in the tropical rain forest. At any given time, at least one species will be flowering.
