Environmental Problems: Solving through Scientific Approach

Updated on May 16, 2014

A multitude of environmental problems has evolved because of the carelessness of man that put’s plenty of lives in danger. Some of these are accidents and unexpected while some are put into intention because of their malignant purpose

Man has witnessed for himself the obnoxious end result of some of his answers to environmental setback and realized the intricacy of such problem. He has recognized the truth that as far as unraveling environmental setbacks is alarmed nobody knows everything as there for discussion and working as one for people with various fields of specification.

In addressing environmental problems, we must look upon all angles and knowing its effects. Unless we do so, we must accomplish every challenge and environmental one by one as much as possible. Ecological backlash is a new environmental problem that will appear as a reaction of every action.

Below are some of the ways on how to address some environmental problems which happened in different regions of the world:

Cause of Wide-Spread of Disease and Threat

In Egypt

Aswan High Dam

The project was moved into action to supply electric power, navigation, and irrigation and flood control. With such magnificent purpose, the supporters of the project have no doubts about the proposal since they see that it would really work. But we cannot avoid troubles and problems along the way in doing a project:

(a.) The dam halted the flow of silt created the valley fertile and offset the erosion of the soil from the Nile Delta and now, the valley needs artificial fertilizer.

(b.) The site also aids to fertilize the Mediterranean Sea. After the operation of the dam, the Egyptian sardine catch declined from 18 thousand tons in 1965 to 5 hundred in 1968.

(c.) Because of the construction of irrigation system of the canals and ditches, a snail vector of Schistosoma, a parasitic flatworm was made easy to disperse making localities in Egypt got infected in a very high percentage ranging from 60% to 95% in some localities.

In Leyte, Philippines

Irrigation System

Just like what happened in Egypt irrigation system. The Philippines have also attempted to construct and build Leyte’s irrigation system for farmers in the locality. The project will help and uplift the standard irrigation system of the place for it, take away the farmer’s shoulder the burden of water supply for their crops and in their plantations. But because of the Aswan dam project, a small snail Oncolelania has scattered through the aqueducts of Leyte dispersing the alarming schistosomes.

In Central Africa

Kariba Dam

The Kariba Dam is found between Zambia and Rhodesia on the Zambezi River. The dam was built in the 1950’s to supply adequate hydroelectric power. But some things happened beyond their expectations that dreaded the lives of man living on the place:

(a.) Because of the project, plants slowly invaded the shores of the Kariba Lake that makes a habitat that is very prone for tsetse flies with a scientific name (Glossina) which is a vector of trypanosome infections of man and domestic’s animals in the place. The incidence also cut the country’s protein supply because of the disease the dreaded domestic animals.

(b.) In the relocation areas, wide and extensive erosion have occurred. The reason was because of the negative response of people to relocate by the dam to ensemble their farming methods to the state of their new farm sites.

What is best holistic approach in addressing unexpected environmental problems for you?

See results

In Philippines

Pantabangan Dam

The Pantabangan Dam project has the same side effects of what happened in the construction of Kariba Dam. The project problems were soil erosion that caused high rate of siltation of the lake and the dislocation of the people in the place, right now almost 40k hectares are in need for reforestation (planting trees in a denuded areas). While in Kariba, the relocation of people was pretty tough because they need to adapt to new environment for they want to stay farmers in the land where farming is not suitable because of the unproductive soil.

Endangering the lives of Biotic Components

Louisiana Alligators

Animals are being labeled by man if it’s “beneficial or pest” in his ecosystem. In some places, alligator might be a threat to people for it kills however, in some places it is considered useful because it is a source and can be made into bags, belt, shoes and other items that are made of alligator’s skin.

But because of this, during the period from 1950 – 1960, almost 90% of Louisiana’s alligator population disappeared and made their specie got endangered. Alligator perform an important role in preserving the ecological equilibrium of their ecosystem. The deep holes they dig keep hold of the water during dry seasons, creating a refuge and shelter to birds, fishes and some animals.

As they go through the waterways, they stir up the bottom sediment thus keeping the channels open. They also feed on gar and other predator fish, serving as a natural check to the latter’s population growth. Some disagreeable events accompanied the massive extinction of alligators. Decreased population growth of predator’s fish and clogging of water-ways ruined plenty other species in the habitat.

Mongooses | Source

Hawaii’s Rats and Mongooses

In 1883, Hawaii’s sugarcane plantation owners have settled to make actions to exterminate the rats that infested their farm crops. In order to control the rapid growth of rats, they decided to use biological control by importing 36 mongooses, a predator that feeds on rodents (rats). But the solution becomes another problem because mongoose hunts prey at daylight while rodent’s hunts at night so probably they will not meet.

It was a mess, instead of having one problem it becomes two; mongoose outrage and uncontrollably feed on chickens, ground nesting birds and their eggs during daylight and rats attack sugarcane and other crops on nighttime. So it is really important to study and cautious enough in solving an environmental problem for it might be another start of a new problem than extinction of another.

Michigan’s Pesticide Problem

Insects and other pest causes decrease of crop’s production and these are controlled and reduced using sprays and pesticides. In 1960’s the people of Traverse City, Michigan used DDT (Dieldrin and Chlordane: these are chlorinated hydrocarbons) to safeguard their cherry orchards along Lake Michigan. After a while the following side effects were discovered:

(a.) The long lived pesticides accumulated into the food chains and concentration was magnified at each trophic level that causes biological magnification. Some fishes that are poisoned are swept by the big waves and got eaten by sea gulls, the sea gulls got the poison and as a result fewer eggs with very thin shells and other ought to hatch.

(b.) Because of the decrease of sea gull population, the dead fish and garbage were left of the beach and seashore as scavengers (sea gulls) starts to gone. In 1969, because of the result Michigan banned the sale of DDT and other related products.

Spreading Deserts

In Sahel in West Africa, people have attempted to elevate their protein supply by raising more cattle and goats at least twice the carrying capacity of the grazing land. Because of these, overgrazing have occurred and destroyed the land cover, leaving an arid sandy soil and widely scattered trees.

According to the United Nation report, some 14 million to 17 million acres of arable land become stony or sandy waste every year. The same ecological tragedy has occurred in the Western Rajasthan region of India of about 500 000 square miles have been rendered unproductively by centuries of overgrazing and elevated cultivation. The incidence is happening in Arizona and New Mexico where until the mid 1970s the Navajo Indians were tending 140 000 sheep on the land that could sustain only 16 000.

      Hi sheilamyers: You are right, studying well the project and knowing its impact will be a clever move to avoid unexpected problems in evolving. Some people do whatever they wanted without knowing its impact to others, just like projects, we must be so careful enough in impleting and doing projects for it will really affect people in the area.

      Thank you for the read sheila :)

      Thanks for making people aware of the negative impacts of the various projects you mentioned. Most people only want to see the good and they'll say it outweighs the bad ... but most of those people don't have to live with the problems. I believe the best way to alleviate the problems is to do better environmental impact studies before starting the project. I know no one can predict all of the negative effects, but they could find most of them. The project can still go on; however, thinking ahead would lead to building in solutions as the project is underway.
