Why Don't We Just Eradicate All the Mosquitoes ?

 

Why Don't We Just Eradicate All the Mosquitoes ?

The extinction of the creatures surely have an impact on the ecosystem as a whole. Mosquitoes are one of the insects that have been around since the time long ago. Researchers estimate, these insects have lived side by side with the other creatures on this earth since 100 million years ago. Of the more than 3,500 species of mosquito in the world, there are really only hundreds of species that infect humans. But undeniably, mosquitoes become one of the main enemies because transmit deadly diseases.

Various efforts ever undertaken by humans to eliminate mosquitoes, especially certain types that transmit the disease. Most of it is still limited research in the laboratory, but the outlook is promising.

One of them was made by a team from the University of Oxford. Genetic engineering team successfully created male mosquitoes that if marrying the female mosquito will produce wingless mosquitoes.

Although it can bite, the mutant mosquitoes can not fly because they do not have wings. Because female mosquitoes have to fly to be able to drink the blood, eventually mosquitoes can not breed and become extinct.

With the same technology, a team from the University of Arizona also produced anopheles mosquitoes resistant malaria virus. Although not intended to exterminate mosquitoes, it also aims to eliminate malaria.

If the mutant mosquitoes could be mass produced and released into the nature and causes of extinction, such as the impact of what would happen?

Quoted from Nature, the greatest impact of mosquito extinction will occur in tundra habitat (ice field) at the north pole. The venue is the biggest hotbed for mosquito species Aedes impiger and Aedes nigripes, migratory birds will be reduced by 50 percent due to a decrease in the bird's favorite foods.

Migration of other animals will also be affected, among other similar caribou or reindeer. Thousands of caribou that were previously avoiding mosquito bites will invade the tundra region, followed by the wolves who are the main predators of the caribou.

Species of mosquito-eating fish, Gambusia affinis also endangered if the mosquitoes are gone. The extinction of the fish is a little more would also have an impact on the food chain that occurs in freshwater.

Moreover, larvae or mosquito larvae also play a role in the decomposition of organic waste. While in a puddle of water, the larvae get nutrients to grow from the remains of decaying plants.

However, many of the judge, the impact of which occurred in the ecosystem is comparable to the death rate in humans from mosquito bites. Malaria, for example, recorded 247 million deaths worldwide each year.

Moreover, experts believe, the various types of insectivores (insect eaters) will not be too difficult to adapt to switch prey on other insects if it were no mosquitos. As for the decomposition of organic waste, the role of mosquito larvae is not indispensable because there are many other types of decomposers. - Why Don't We Just Eradicate All the Mosquitoes ?

Who Is Actually The Largest Provider Of Oxygen For The Earth ?

 

Who Is Actually The Largest Provider Of Oxygen For The Earth ?

If you answered : Trees

The answer : sorry .. you are still wrong .. the tree is one of the contributors of oxygen, but only by 20% for the earth. Trees are useful to mitigate (reduce) the carbon dioxide that is in the earth. So to reduce the impact of global warming, plant a tree so that its CO2 can be utilized by the tree. Because the fair value of CO2 is 0.1% in the earth, but the year before CO2 levels in the atmosphere has reached 0.3%.

So the correct answers are : 

Do you know who it is?

Yap the answer is Plankton, particularly phytoplankton.

Plankton are defined as any drifting organisms that live in the pelagic zone (top) ocean, sea, and fresh water bodies. Plankton widely regarded as one of the most important organisms in the world, because it becomes food for aquatic life.

For most sea creatures, plankton is their main food. Plankton consists of the remains of marine animals and plants. The size is small. Although similar objects including life, plankton do not have the strength to fight the current, tide or wind that presents itself.

Plankton living in coastal areas where it gets supplies of mineral salts and sufficient sunlight. It is important to allow it to continue living. Given the plankton into fish food, not surprising that there are a lot of fish on the coast. That is why active fishing activities carried out in the region.

In addition to the remains of animals, plankton are also created from plants. When viewed under a microscope, plant elements can be seen in the plankton algae. Some sea creatures that feed on plankton are like rocks, shells, and whales.

Plankton are organisms which accounted for 80% of the oxygen that exist on this earth. With the ability respiring produce bubbles of oxygen contained in the sea, the oxygen is released into the air and into a gas that we can enjoy today.

Scientists from the United States found plankton can indirectly create clouds that can withstand most harmful sunrays. So that plankton can help slow the process of global warming.

Dierdre Toole of the Woods Hole Oceanographic Institution (WHOI) and David Siegel of the University of California, Santa Barbara (UCSB) are two researchers.

Dierdre Toole

David Siegel

The study, funded by NASA revealed when the sun is shining on the ocean, the upper layer of the sea (about 25 meters above sea level) heats up, causing a high enough temperature difference to the marine layer underneath. The top and bottom layers separately and not mixed with each other.

Plankton living in the upper layer, but the nutrients required by the plankton there is more in the lower layers of the ocean. Therefore, plankton are malnourished.

Due to the condition of malnutrition coupled with the hot water temperature, plankton stressed so more vulnerable to ultraviolet rays that can damage it.

Because susceptible to ultraviolet rays, plankton try to protect themselves by producing substances dimethylsulfoniopropionate (DMSP), which serves to strengthen their cell walls.

This substance decomposes into water if a substance will be dimethylsulfide (DMS). DMS then detached itself from the sea surface to the air.

In the atmosphere, DMS reacts with oxygen to form sulfur similar components. DMS sulfur components were then attached to each other and form small particles such as dust. These tiny particles are then easier for water vapor from the ocean to condense and form clouds.

So, indirectly, plankton help create clouds. Clouds are formed causing the less ultraviolet light that reaches the surface of the sea, so that the plankton were freed from disturbance ultraviolet light.

This process actually has several years studied in the laboratory by scientists, but only this time the natural process can be studied.

Cloud caused by the plankton, is believed to slow down the process of global warming, as well as having a large effect on the Earth's climate. However, to prove this, further research remains to be done careful.

Research conducted in the Sargasso Sea, off the coast of Bermuda also find it surprising that this DMS particles can decompose by itself in the air after only three to five days. In fact, carbon dioxide in the air, can last up to decades. - Who Is Actually The Largest Provider Of Oxygen For The Earth ?

10 Types Of Endangered Animals

The extinction of at least 500 species of animals have been caused by humans, most of the extinction of these animals occur in this century. It's still about 5,000 endangered animals and at least one species die every year. That number continues to grow rapidly where some species becoming endangered without our knowledge. Value of the animals is very important, because they can be used for a variety of useful medications.

The following are some of the most endangered species of animals around the world :

1. Horseshoe Bats

There are fourteen types of bat in Britain and all of them are under threat. Horseshoe bats are bigger than others is one of the rarest. Current estimates range between 4,000 and 6,600 individuals. They also suffer because of the use of insecticides (poisonous chemicals sprayed on crops to kill harmful insects) which have been kill insects that are the main source of their food.

2. Siberian Korean tiger

The Siberian tiger is a rare subspecies of tiger. The type of tiger is also known as the Amur tiger, Korean tiger , Manchurian tiger, or North China Tiger. Its habitat is located in the Amur region in the Far East and have protected status. The Siberian tiger is considered as the largest subspecies of the six subspecies of tigers. Siberian tigers are endangered. These animals are hunted because of the price of a tail can feed a family for one year (it is so expensive).

3. Loggerhead turtle

Loggerhead sea turtles once intensively hunted for their meat and eggs. Additionally turtle fat is also used in the cosmetic industry. Many of these animals die annually caught in the fishing nets. In Turkey, a hotel was built right at the turtle farm site.

4. White-tailed Eagle

Before man experimented with the use of pheromones, a spectacular bird of prey far more than it is today. They have also been hunted by shepherds and hunters who regard them as a threat to their sheep or birds. Intense with conservation measures, the eagle population in Eastern Europe began to recover, the recovery plan aims to put some traditional breeding areas in Europe.

5. Mandarin duck

Mandarin Duck is a medium-sized duck that has a kinship with the North American Wood Duck. This duck has a length of 41-49 cm and 65-75 cm wingspan.

This beautiful bird extinctions caused mainly woodcutters and poachers. In addition, because predators such as mink, raccoon dog, otters, polecats, eagle owls and grass snakes.

6. Lion Tailed Monkeys

These animals live in several areas in Karnataka, Kerala and Tamil Nadu. Currently, tropical forests, which is a natural habitat of these monkeys, has been cleared and replaced with tea and coffee plantations. As with so many mammals, currently the main threat is habitat destruction. Also often arresting poachers baby monkey, and kill them in the process of holding the hunt, and then exported to illegal collectors. They are regarded as the most endangered monkey, with only 400 individuals remaining in the wild. They are hunted for their meat and fur.

7. Jackass Penguin

It is the only penguin species of birds that exist in South Africa. Because they live so far in the north, and in areas that are relatively accessible, African penguins are susceptible to killing by humans. Oil pollution also threatens them, as well as egg collection for food.

8. Mountain Gorilla

Virunga, a volcanic region in eastern Zaire, Rwanda and Uganda are the only home of the mountain gorillas are critically endangered at this time. They are often killed by traps and jeratn are intended for other animals, their habitat loss and are highly susceptible to many diseases just like humans. They are very dependent on dense forests for survival continuous land cleared for crops and livestock. Humans and gorillas 98% genetically identical so they are also exposed to human disease. This species is the most endangered of the gorilla subspecies, only about 700 mountain gorillas remain in the wild.

9. Numbat

Inhabit the forest on the west side of Australia, this is the only country where they can be found in the wild. They survive in the wild only in a small area in the southwest corner of Australia. When humans introduced predators such as cats, dogs and foxes, they prey on many numbats. Their numbers are declining due to many areas of their habitat are cleared for agriculture and mining.

10. Black footed Ferret

This is one of the most endangered mammals in North America, the animals at the edge of the Black Footer Ferret extinction in the wild. extinct in the wild. Loss of habitat is the main reason black-footed ferrets remain near the brink of extinction. Remaining prairie dog colonies are small and fragmented, separated by a large cropland and comprehensive human development. In 2010, biologists hope to have 1500 ferrets established in the wild, with no fewer than 30 breeding adults in the population, respectively. - 10 Types Of Endangered Animals

3. African Lungfish

This river is quite strange creature in my opinion. For people who have never seen it, would have thought this creature as a monster because of the creepy. However, despite the terrible shape, these animals are completely harmless. This fish adapt to its environment which less oxygen, so that makes this fish rarely seen by humans.
