The LDPE m a recycling  symbol for plastics,bottles and packaging.The LDPE is commonly used in wire and cable jacketing The LDPE  is used becauase of its flexibility and rtoughness and it is used  in applicastions where heat sealing is neccessary,the ldpe is also easily used for processing..The ldpe can be described as tough,fle

xible and it has an amazing strnght.

I was assigned to fish BWI1 and I have observed the growth in that plant is extremely better than the growth of my plant at home. The plant has grown thick and seems to

be so healthy in comparison to my plant at home. There are several differences between my plant at home and the plant in the lab with the fish, one obvious observation I made was that the roots of the plant with the betta fish is extremely thin but very long, whereas the roots of my plant at home is a thick full bunch.MY plant at home has bloomed one flower already and three more buds has grown, but the BWI1 plant has no flowers yet.I have also noticed that none of the plants with fish has had any bugs on them whereas my plant, as I have mentioned earlier, has had mealie bugs , so the environment in which the two sets of plants is growing in is also affecting the growth of the plants.

Overall BWI1 is in much better condition than my hypoestes at home, this must be due to the fact that within the plant and fish system there is a nitrogen cycle present whereas my plant is in a completely un cycled system.

I finally found out the reason why my plant was not growing anymore and the culprit was Mielie bugs. I saw these white bumps on the stem of my plant but I did not really take note of it, I just thought it was meant to be there. I only realized that the white bumps was not meant to be there when I observed all the other plants in the lab and those plants did not have any white bumps. Luckily Allison told me her plant had mealie bugs and the description she gave of it sounded exactly like the white bumps I observed.

Now that I finally knew what the cause of my plants slow death was I could finally do something about it. Root Mealie bugs are small white powdery substances that are found around the root of the plant and they suck the plants sap and kill the leaves of plants. To kill these bugs you can physically scratch it off with an old toothbrush dipped in a little methylated spirit. I did not have any methylated spirits but Dr Richard Knight had told me I can even spray a little dishwasher water onto the plants or just physically scratch it off and that is what I have done. I was able to remove most of the bugs off from my plant. I removed the bugs on the 21 April and already my plants has started showing growth improvements, the two buds that were present are growing again and there another flower bud has appeared, the plant has started growing sprouts again. So I’m very pleased that my plant is growing once again.

ESS has taught me a lot about the environment and how different organism  live and interact with each other but I have to be honest ESS121/131 isn't what I thought it would be, I thought it would be more geographic like we would learn about climatology and. ESS has, however, taught me  a lot about the environment and how organisms adapt to new habitats

FOOD FOR THOUGHT

Ever wondered to yourself how much damage is caused by manufacturing of cotton and leather clothing? Have you ever thought of a different source for covering your body? What if that source of clothing was made of unuseful products? Well if you have not thought about it some people have.

Of cause whenever I see something that could be environmentally friendly, I share it with you and hear your opinions. The following is designs of clothing that were showcased at an event I attended in the past weekend made with plastic, paper and flora material.

DESIGNS FROM NATURE

If we could find more innovative ways to sustain these types of clothing to last longer, we might as well introduce them to more people around the globe but baring in mind that whatever implication we add should not move away from the concept of the clothing being environmentally friendly and sustainable.

Interesting facts about the BETTA Fish

The betta got its name from an ancient clan of warriors, called the "Bettah."  The fish were given a combatant name after the fighting fish became popular in the mid-1800s.  In fact, the sport became so renowned in Thailand that the former King of Siam had it regulated and taxed!  Spectators of the sport based their bets on the bravery of the fish, rather than the damage inflicted by the victor.

Bettas, unlike other species, are not schooling fish and will fight with each other, regardless of gender.  Bettas prefer to swim alone and also need a comfortable place to hide.  Aquatic caves or dense, planted corners work great in making a betta feel safe

Interesting betta facts

* Bettas prefer slightly acidic water (pH 6.5 to 7) and warm water.  Cold water can suppress the immune system and cause illness.

* Betta's have several different tail shapes - the most common being the "veil tail."  Other tail shapes include 

the "half-moon," "double tail," "short-finned fighting-style tail" and "crown tail."

* Bettas normally live 2 - 3 years, but there have been a few cases of bettas living well into their teens.

 * The betta is known as "plakad" in its native Thailand and has often been referred to as "The Jewel of the Orient."

History of the BETTA Fish

 

History

The betta was first discovered in Southeast Asia.  Making its home in rice paddies, drainage ditches and the warm flood plains of the region, the betta became accustomed to frequent storm flooding and devastating droughts.  The cyclic, drastic changes in its environment helped the fish to adapt - becoming a true labyrinth fish.  A labyrinth fish has the unique ability to breathe oxygen directly from the air and also take in oxygen from its gills.  As a result, bettas and other labyrinth fish can survive for short periods of time out of water and if needed, can inhale the air around them (provided they stay moist.)  This also explains why a betta can sustain itself in stagnant, oxygen-deficient water.  Although bettas can tolerate small spaces and poor water quality, they do best in small aquariums (at least two gallons) with regular water changes.  The preferred water temperature for a betta is 47.5-51.25 degrees C
