Preserving Our Rainforest

One of the most beautiful creation that God did created is the rainforest. It contains more species o plants and animals than any other habitat on earth.
The great rainforests are the forest of South America, Africa and Southeast Asia. The tropical climate here is always warm and wet, with no winter, and plants grow all the year round. 
As a result, trees grow thickly, ferns, vines and other plants.
These help support an extraordinary rich variety of the life of animals, particularly birds and insects.

The rainforest is a place where plants grow rapidly and to reach the sunlight trees grow very tall. There are three distinct layers of rainforest. The forest floor, the understorey and the canopy.

The main canopy is usually between 30 to 50 meters above ground, where the slander trunks break into cluster of branches. The tallest trees reach even higher, to around 60 meters. The canopy shades the understorey from the sunlight, and here it is much darker.

The understorey consists of tree trunks covered with lianas (climbing plants) and laced together by creepers.

The forest floor is surprisingly free of clutter. Leaves, fruits, animal droppings and bodies of dead forest animals decomposed quickly when they fall into the ground. Their chemicals are absorbed as nutrients by plants roots and used to make new growth.

Sad to say that trees of rainforest are being used as timber, and large areas of rainforest have been destroyed by logging. Vast areas of rainforest were being cleared to make way for plantations of other products. Often this is done by cutting trees and burning shrubs. When trees are cleared from the hillside, the soil maybe left exposed and when heavy rain falls, thus resulting soil erosion.

We need the rainforest. They act as the earth's lungs by giving off oxygen into the atmosphere. Plants are also used as medicine. Let's help preserve our rainforest by cooperating with the government law of protecting our rainforest.

Preserve Our Ocean Life

As we know that nearly ¾ of the earth’s surface is covered by water. The deep and wide oceans, they are the homes of countless living creatures from the smallest to the biggest one.
Our world has four oceans namely: Arctic, Indian, Atlantic and the Pacific. The biggest of them is the Pacific. It is the biggest and deepest ocean among them.



The ocean has two main zones, the ocean basin (the deepest part) and the shallow continental shelf at the edge of the land. Along the coast, the seashore forms a constantly changing margin between sea and land. There are different types of shoreline where coastal rocks are soft, features such as clefts change quickly. Hard rocks wear away slowly. Even the everyday action of a relatively calm sea will erode the shoreline.

The oceans have been used by humans for thousands of years. It became their source of food, means of transport in ships, and as a dumping ground for waste. Fishing is an ancient human activity. Humans are not satisfied by the way they catch fish. They try to discover modern ways on how to catch large amount of fish. They use modern vessels, large nets, devices such as radar for tracking fish shoals. Today, valuable food fish are becoming rare in areas where they once numbered millions. Because of the modern fishing methods that are simply too efficient. Nets often trap immature fish which have not yet been able to breed.

The oceans have become a dumping ground for all kinds of rubbish. Every year more than 3 million tons of oils are spilled into the sea. Much of this is washed out of the tanks of oil tankers before they reload. About half of the pollution of the oceans is caused by waste dumping. Domestic wastes are being dumped into the sea. These cause problems, because they will not decay naturally and so remain a lasting danger to wildlife. Chemicals are often toxic to people, as well as to fish.

The whales were also sea living creatures. Today, whale hunting become so relevant because of the demand of whale oil and other product s that comes from whale. How can we save our whale if nations will not cooperate in whaling bans which can help save the little remaining species of whales?

The coral reefs are the earth’s oldest living communities. Most of them are between 5,000 and 10,000 years old. They are rich in wildlife species like the rain forest. A single reef may contain 3,000 species of coral, mollusk, crustacean and fish. The delicate population of reefs is easily damaged by the population of the water, removal of coral for sale as a souvenir and over-hunting by spear fishers. How can we protect them if we try to continue on abusing them.

Such attitude of humans if not being change will make our world lost its sea living creature. Let’s remember that these species are a great help to us. Help preserve our sea living creatures. Let’s support government program in protecting them. Let’s take care of the beauty of nature that God has given us.

Restore our Rivers and Streams

If we try to look at our rivers and streams, hence we can say that it really needed restoration. Almost of our rivers today lost its beauty and we cannot see living creatures enjoying swimming in its rich and bountiful water due to abuse of nature.

The restoration of rivers and streams has attracted increased interest and funding in recent years, as a result of legal requirements to mitigate damage to important habitats and as a positive avenue through which citizens can take steps to improve their environment.  River restoration is undertaken for a variety of goals, including restoration or enhancement of aquatic and riparian habitat, provision of functional recreational corridors in urban areas, and to improve water quality.  River restoration activities include recreation of meander bends on straightened channels, modification of channel geometry to create habitat for fish, planting banks with riparian vegetation, and creating open channels from streams formerly encased in underground culverts.  Ironically, the attractiveness of river restoration today is possible only following the elimination of point sources of water pollution effected in recent decades (in the US as a result of the Clean Water Act).

River and stream restoration does not constitute a separate field or a unique bag-of-tricks to be used on degraded rivers.  Rather, restoration involves the intelligent and integrated application of knowledge and techniques from other fields, such as ecology, hydrology, and geomorphology.  While the goals of restoration projects are often ecological in nature, the hydrology and geomorphology of the channel commonly determines whether the project ultimately achieves its objectives.  (As noted by the National Research Council in its 1992 report Restoration of Aquatic Ecosystems, many river restoration projects have failed because they were based more on 'folklore' than sound hydrologic and geomorphic analyses.)   Thus, the application of sound geomorphic analysis is prerequisite to successful restoration planning and design.

Each of us need to contribute for rivers and streams restoration in order to bring back the environment which we have before for the future of our children. Preserve nature, restore the rivers and streams.

Help Preserve Natural Resources

Natural resources plays a great help in nature. Many nations create laws which will help to preserve natural resources but sad to say that people still abuse our natural resources and the result is, it is still human beings who suffer its effect.
As we see our natural resources are becoming increasingly stressed as a greater demands are placed on their ability to provide us with their life giving services.

As the trees were cut down, lakes were drain, rivers and aquifers, and the land in the cities which are productive were covered. Due to human's ability in doing what should not be done to our natural resources, the result is, our natural resources lost its capacity to provide for us exactly what we need. On the other hand, our action reduce the amount of resoures that are available in the first place. We need to preserve the limited amount of natural resources that we do have, so that the earth can continue to provide.

Just think of what our natural resources provides for us everyday and we need not to pay for it, it's free. Our natural resources provide us with an immense amount of services everyday, which we as humans do not value very well because we do pay for it. We should learn how to value it because it was given by God and it is a great blessings on our part.

Sad to say that though how many times the government implement laws, give warnings, but still humans abusive atitude made it to become little by little everyday. They are destroying the natural resources just for their own good. They never thought of the generations to come. What will they be? Who will give them fresh air to breathe everyday, clean water to drink and clean and beautiful surroundings to live in. If today no one ever cared for the natural resources who freely gives us these things and we never pay for it. It's the gift of nature.

We should help in conserving our natural resources not just for today but for the generations to come.
