Scientists finally concluded that, for the seeds of the calvaria tree to sprout, they needed to be digested by the dodo bird. By force feeding the seeds to a domestic turkey, who digested the seeds the same way as the dodo bird, the trees were saved. Unfortunately, humans will not be able to save each species in this same way. Each species has evolved with its own set of unique adaptations, ways of helping them to survive. Every animal has the ability to protect itself from being someone s next meal. To prevent the extinction of a species each and every species must develop a defense tactic.

The fruits and nuts from many trees have evolved with a tough shell to protect them from predators. In turn toucans and parrots developed large, strong beaks, which serves as a nutcracker and provides them with many tasty meals. Many animal species paper have developed relationships with each other that benefit both species. Birds and mammal species love to eat the tasty fruits provided by trees. Even fish living in the Amazon river rely on the fruits dropped from forest trees. In turn, the fruit trees depend upon these animals to eat their fruit, which helps them to spread their seeds to far - off parts of the forest. In some cases both species are so dependent upon each other that if one becomes extinct, the other will as well. This nearly happened with trees that relied on the now extinct dodo birds. They once roamed mauritius, a tropical island located in the Indian Ocean. They became extinct during the late 19th century when humans overhunted them. The calvaria tree stopped sprouting seeds soon after.
A few supermarket hours of poking around in a rainforest would produce several insects unknown to science. The constant search for food, water, sunlight and space is a 24-hour pushing and shoving match. With this fierce competition, it is amazing that that so many species of animals can all live together. But this is actually the cause of the huge number of the different species. The main secret lies in the ability of many animals to adapt to eating a specific plant or animal, which few other species are able to eat. An example of such adaptations would be the big beaks of the toucans and parrots. Their beaks give them a great advantage over other birds with smaller beaks.
Living in limited areas, most of write these species are found nowhere else on parts earth. For example, the maues marmoset, a species of monkey, wasn t discovered until recently. It s entire tiny population lives within a few square miles in the Amazon rainforest. This species of monkey is so small that it could fit into a persons hand! In a rainforest, it is difficult to see many things other than the millions of insects creeping and crawling around in every layer of the forest. Scientists estimate that there are more than 50 million different species of invertebrates living in rainforests. A biologist researching the rainforest found 50 different of ants on a single tree in Peru!
During the ice ages, the last of which occurred about 10,000 years ago, the frozen areas of the north and south Poles spread over much of the earth, causing huge numbers of extinctions. But the giant freeze did not reach many tropical rainforests. Therefore, these plants and animals could continue to evolve, developing into the most diverse and complex ecosystems on earth. The nearly perfect conditions for life also help contribute to the great number of species. With temperatures constant at about 75-80 degrees Fahrenheit the whole year, the animals don t have to worry about freezing during the cold winters or finding hot shade in the summers. They rarely have to search for water, as rain falls almost every day in tropical rainforests. Some rainforest species have populations that number in the millions. Other species consist of only a few dozen individuals.

Conclusion; At the present rate of destruction, all existence of rainforests will have disappeared at the end of the century. In the 1950 s there was over 950 million hectares of agriculture, and in the 1970 there declined a astonishing 200 million hectares. It is estimated by the year 2000 that there will be 500 million hectares persevered. Science ;Rainforests and Earth The Tropical rainforests of the world In this term paper, i will explain the great importance of the tropical rainforests around the world and discuss the effects of the tragedy of rainforest destruction and the effect that it is having. I will talk about the efforts being made to help curb the rate of rainforest destruction and the peoples of the rainforest, and I will explore a new topic in the fight to save the rainforest, habitat fragmentation. Another topic being discussed is the many different types of rainforest species and their uniqueness from the rest of the world. First, i will discuss the many species of rare and exotic animals, native to the rainforest.
Tropical annual rainforests are home to many of the strangest looking and most beautiful, largest and smallest, most dangerous and least frightening, loudest and quietest animals on earth. There are many types of animals that make their homes in the rainforest some of them include: jaguars, toucans, parrots, gorillas, and tarantulas. There are so many fascinating animals in tropical rainforest that millions have not even identified yet. In fact, about half of the world s species have not even been identified yet. But sadly, an average of 35 species of rainforest animals are becoming extinct every day. So many species of animals live in the rainforest than the any other parts of the world because rainforests are believed to be the oldest ecosystem on earth. Some forests in southeast Asia have been around for at least 100 million years, ever since the dinosaurs have roamed the earth.
When trees are extracted from our environment the rain can t be absorbed and so it eventually starts washing away the top layer of soil. Therefore after a rainforest is destroyed it can never be replaced. Ever so the ecosystem is very fragile and will be damaged. Solutions to deforestation; Current methods have been established to assist with the conservation of plant and animal life. Many have to do with the preserving and protection of rainforests.
The government has made more local people aware of what consequences could eventuate from the destruction of forests. The increase of carbon dioxide is just another focus point. Due to the lack of nutrients plant life can not adapt to the region, leaving the crops sustained from annual growth. However a various type of palm adapts naturally to the soils, which can help reduce soil erosion. Although soil erosion has a big impact on our environment logging raisers another question. Luckily a policy called Selective logging has resolved the devastation of forests. It enables people to only cut down some trees, not the entire forest. These practical solutions will all help stabilize deforestation.

This modern technology has boosted the rate of deforestation and will continue to. The consequences of deforestation; The removal of forests does not always provide a suitable land for growing crops. When agriculture has been converted into wasteland the ground has a poor tenacity of nutrients, which means plant life will not be able to prosper in the environment. After the rainforests have been cleared the land will only remain fertile for very few years. These extensive land areas can only grow crops for a short period of time. Rainforests are accountable for our annual rainfall, since trees absorb enormous amounts of water. They are also known to leave the atmosphere dense and oist. This can lead to serious side effects if our forests continue to be destroyed. Such as drought, flooding and more inclined to soil erosion.
Rainforests are said to be inconvenient obstacles. They re simply removed from nature mainly due to lack of space for pasture etc. More easons to why people continue to cut down rainforests, is in addition to timber. Timber is means of paper and is valuable resource in most countries. Mahogany and teak has been known to have high priceless values. Over the past years there has been tremendous change in the cutting down of trees. Heavy plant and machinery like bulldozers and cranes can clear large amounts of our forests in a third less time then it takes men with axes.
There is little questioning about the survival of rainforests in type the future. Why do our forests continue to be destroyed? Rainforests all over Australia has been descending at a rapidly low pace. These problems have arisen mainly due to human activity. The influence of humankind has played a major factor in the role of deforestation. Modern machinery is another example for which our rainforests are eing cut down. Millions of hectares every year of agriculture have previously been demolished, and every half an hour an animal specie becomes extinct.

Rainforests are business known for their distinctive features and natural beauty, and are among the richest inhabitants in the world. They contain several different species of animals and provide an essential home for wildlife. Many different rainforests that are located in Australia are found in the northern region. It is heavily populated between Townsville and cook town. These unspoiled creations of Mother Nature have already been completely destroyed, along with Their animal life. In fact very few rainforests are left in Australia and are under reat threat. We will Write a custom Essay sample.
