terrarium

A terrarium (plural: terraria or terrariums) is usually a sealable glass container containing soil and plants, and can be opened for maintenance to access the plants inside. However, terraria can also be open to the atmosphere rather than being sealed. Terraria are often kept as decorative or ornamental items. Closed terraria create a unique environment for plant growth, as the transparent walls allow for both heat and light to enter the terrarium. The sealed container combined with the heat entering the terrarium allows for the creation of a small scale water cycle. This happens because moisture from both the soil and plants ev***rates in the elevated temperatures inside the terrarium. This water vapour then condenses on the walls of the container, and eventually falls back to the plants and soil below. This contributes to creating an ideal environment for growing plants due to the constant supply of water, thereby preventing the plants from becoming over dry. In addition to this, the light that passes through the transparent material of the terrarium allows for the plants within to photosynthesize, an important aspect of plant growth.

Let's Keep and Save our Earth

Earth Day was initiated a senator Ga***rd Nelson called America. Earth Day this becomes a manifestation of environmental concern in 1970
The struggle of Ga***rd Nelson started around more than 7 years before the first Earth Day.
At first Ga***rd hopes his thinking is achieved through the visit that President Kennedy performed the 11th State in September 1963, but by some reason the visit is not able to bring environmental issues into the national agenda. Continue efforts to realize his idea of Ga***rd. After a tour of Kennedy, Ga***rd did his campaign itself to some States. In all corners of the country, evidence of environmental degradation occurs everywhere. Everyone is aware of it, unless the political circles.

Finally in the summer of 1969 Ga***rd knowing that anti-war demonstration action Viet Nam had spread widely through the community colleges around the country. From there he got the idea to do the same thing in a campaign environment. He chose among the bottom in doing action protests against environmental damage. At a Conference in Seattle September 1969, Ga***rd announced it will hold nationwide demonstrations in the spring of 1970 on behalf of the environment and everyone is invited to participate. After that, various letters, telegrams, and telephone flows from across the country. Americans finally found a forum to express it over a decline in the quality of the soil, rivers, lakes and air in their environment. On November 30, 1969 New York Times reported the occurrence of an increased activity of the concern for the environment all over the country especially on college campuses and one day for the commemoration of the central environmental problems designed for the upcoming Spring for coordinated by Senator Ga***rd Nelson. This is a proof of the success of the struggle of Ga***rd Nelson in promoting environmental issues as a national agenda.

On April 22, 1970, about 20 million Americans took to the streets as well as meet a number of garden and auditorium to support the health and sustainability of the environment. Thousands of students gathered against environmental damage. Groups that already have long been opposed to the presence of the oil spill on the environment, factories and power plants cause pollution, poor sewerage disposal, hazardous materials, pesticides, freeways, the loss of wilderness, and increasingly aware of wild life punahnya togetherness over their struggle from the community.

well that was then a glimpse of the story or history from the birth of her earth day. Earth Day was born as a form of awareness will be the salvation of the planet.

but to keep our Earth. We should not celebrate or keep our surroundings only when earth day only, but every day we have to keep our environment.

protect our Earth by always disposing of trash in its place, not cutting down trees recklessly or if need not use a motorized kedaraan. or it could be using the bike when going to the campus because when bad habits remain our Earth will be damaged and the impact will we feel little by little.

Clean Water

Is The Source Of A Healthy Life
Water is indeed a source of life. However, the dirty water is not the source of a good and decent life for mankind. Not only for human beings, clean water is also sorely needed by other beings like plants and animals to make a living.

Based on data reported by UNICEF and the WHO, Indonesia is one of 10 countries that almost two-thirds of the population have no access to clean drinking water.

The water is not clean can not only affect health, but also the safety and quality of life of children. UNICEF estimates as much as 1,400 children aged below five years die every day due to diarrheal diseases that are closely related to the lack of clean water and adequate sanitation and hygiene. Even annually, Indonesia suffers a loss of USD 6.3 billion due to bad sanitation. By improving sanitation, Indonesia could potentially contribute USD 4.5 billion for economic growth.

Then, if the clear water we see everyday, drink, and use the already healthy and actually it was really worth it? From where we know the water is clean. Citing the decision of the Minister of health of the Republic of Indonesia Number 1405/menkes/sk/xi/2002 about the health requirements of Office and industrial work environments, clean water is water which is used for daily necessities and quality meet the requirements of health clean water in accordance with the legislation in force and can be drunk when cooked.

The following is a characteristic of a decent clean water for consumption:

Physical condition:
a. the display must be clear and not turbid
b. any colorless
c. do not feel any
d. odorless apaun
e. temperature between 10-25 ° C (cool)
f. do not leave deposits

Chemical terms:
a. do not contain chemical ingredients which contain toxins
b. do not contain chemical substances overload
c. Sufficient iodine
d. water between pH 6.5 – 9.2

Microbiology terms:
Does not contain the germs of diseases such as dysentery, typhoid, cholera, and pathogenic bacteria cause disease.

The many ways that we can do to conserve water usage in the home. According to the Directorate General of water resources, the Ministry of public works, there are some things that can be done:

When using the washing machine, use the full capacity. That way, the water used can be more efficient. It is also recommended to use the automatic clothes washing machine so that it is able to conserve more water.
Wash in large quantities will be more efficient than water a bit, but often. If you don't use the washing machine, don't rinse immediately under the faucets, but tampunglah the water in the bucket to rinse.
Use water as necessary. Not that stingy water and finally not clean. For example, do not take a bath in a long time. When using the shower (shower), use a weak glow because it could save berliter-litres of water every minute of it.
Installing a shower in the bathroom is more efficient than using a water Dipper first by means of a dip. Use of the shower three times more efficient than using a Dipper or soak.
Do not allow water to drip from the tap or toilet leaked. Fix soon.
Letting water faucets turned on constantly when we're brushing your teeth, wash your face, or shaving, washing dishes and other very wasteful of water. One minute letting water faucets open, at least 5 liters of water wasted.
In daily activities in the household, do not let the water wasted it when it can still be used. For example, if you wash fruit or vegetables with a flowing tap water tampunglah water. Use the water for watering the plants. So did the aquarium water when want to mengurasnya. The stream of water from the rain gutter can be accommodated or directed at trees and plants.
Use the bucket holding water when washing the car or motor, so as not to waste water flowed steadily out of the hose. If they want to continue using the hose, turn off the water when menyabun and new turn on when rinsing. A quarter hour close the faucets alone would partake save tens of litres of water.
In addition, it is recommended not to use clean water when watering page or plant. Use household waste water that is not too dirty.
Strive to make resapan water wells in Our shelter to replace the water that we consume. Avoid spending all the farm yard with cemented, it's to retain rainwater can seep directly into the ground. In addition to the well resapan, it is worth making biopori to prevent floods and safeguard the survival of the environment around.

Let's fix the perception and mindset about clean water. Don't think we can afford to buy water or pay the electricity from any water pump that we use. As if water is free. But the longer the water is getting scarce and we need a lot of costs for the provision of clean water. Save

plastic waste

One of the factors causing damage to the environment that until now still remains a great "PR" for the Indonesian nation is the factor of waste disposal of plastic waste. Plastic bags have become dangerous and difficult to manage.

It takes tens or even hundreds of years to make the plastic bag waste that is completely unraveled. But the problem is the negative impact of plastic waste is as big as its function as well.

Then do you know what dangers are caused by plastic bags for the environment?

It takes 1000 years for the plastic to decompose by decomposing or completely decomposed soil. This is a very long time. When decomposed, the plastic particles will contaminate the soil and ground water.

If burned, plastic waste will produce toxic fumes that are harmful to health that if the incineration process is not perfect, the plastic will break down in the air as dioxin.

These compounds are highly dangerous if inhaled human. The effects include triggering cancer, hepatitis, swelling of the liver, nervous system disorders and trigger depression.

Biopori

Biopori is also called the biopore absorption hole is a hole made perpendicular to the ground. This hole has a diameter between 10-30 cm and has no shallow groundwater surface. Biopori infiltration or so-called "biopore hole" is an alternative method to increase rainwater absorption into the soil. This method was first coined by Dr. Kamir R. Brata, a researcher and researcher at the Department of Soil Science and Land Resources, Bogor Agricultural University (IPB). The Biopori Infiltration Holes are a cylindrical opening made vertically into the ground. This hole will trigger the appearance of biopori naturally in the soil.

Save Water

In an age filled with environmental degradation as it is today, the difficulty of clean water is a common problem in many parts of Indonesia. That's why many people who suggest to save clean water to ensure the availability of water that we really need this.

I think saving clean water means reducing the use of clean water, such as reducing the intensity of motor-wash, no longer flush homes with clean water to "tame" dust, and even (possibly) reduce the number of baths in a day.

For areas that really lack clean water, the above actions seem to be done. But what about the area with abundant water supply?

Ethically, we do need to conserve clean water, even though we live in areas rich with clean water. This is done one of them in honor of other areas that lack water. However, in my opinion, that does not mean we are obliged to reduce water usage from normal limits.

The intention of saving here in my opinion is to use water SUMMARY alias is not excessive. Because, no matter how much we use water, it can not change the condition of areas that lack water. Unless the water supply in our area is taken to be distributed to the area.

So the point is not to clean water that we use is wasted without shedding something / certain dirt. For example, a disabused motorcycle can be rinsed cleanly using only one bucket of water. Well, if we add another bucket of water, that means we do the use of excessive water, the waste of water as much as one bucket.

Apart from that, there are things that are not less important to do than save water, which is keeping things that can produce clean water, such as multiply planting trees to keep the ground water supply abundant, and of course to preserve the forest.

How do you think?

Little about B3 waste

Dangerous and Toxic Materials or often abbreviated as B3 are substances or other substances which may harm the health or survival of humans, other creatures, and / or the environment in general. Due to its properties, hazardous and toxic materials and wastes require special handling.

Government Regulation No. 101 of 2014 on the Management of Hazardous and Toxic Wastes defines Hazardous and Toxic Substances (B3) as substances, energy, and / or other components due to their properties, concentrations and / or quantities, either directly or indirectly Pollute and / or damage the environment, and / or endanger the environment, health, and the survival of human beings and other living beings. [1]

The materials can then be classified into groups of materials that are:

Explosive;
Oxidizing;
Very flammable;
Highly flammable;
Flammable;
Very toxic;
Highly toxic;
Toxic (moderately toxic);
Harmful;
Corrosive (corrosive);
Irritant;
Dangerous to the environment;
Carcinogenic (carcinogenic);
Teratogenic (teratogenic);
Mutagenic (mutagenic).

The Importance of Owning Awareness of Waste Management.

Waste management is not too difficult for individuals to do independently. The key to be held is a strong will to start and preserve it to other community groups.

The importance of awareness ownership to waste management lies in the effects that waste generates on the environment. In short, waste management will minimize or even eliminate the negative impact that has been more often focused on pollution that led to environmental damage.

By knowing how to properly and properly dispose of waste, we can take appropriate steps regarding how to 'treat' the garbage so as not to harm people per person and its environment.

The next point concerning the importance of waste management awareness is the fact that around us or - in the wider scope - in our country, most landfills and waste management can not be said to meet the requirements to build the health and safety of the environment and its residents. Many can even endanger people with their overly high garbage.

Therefore, if the individual has the awareness to manage the waste in his or her own neighborhood and / or its surroundings, the heavy work of disposal centers and waste management becomes lighter. At least, the potential for pollution and other losses can be minimized.

Greenhouse effect
Naturally the sunlight (short wave radiation) that touches the surface of the earth will turn into heat and warm the earth.

Some of this heat will be reflected back by the Earth's surface into outer space as long-wave infrared radiation.

Some of the heat of reflected sunlight will be absorbed by gases in the atmosphere surrounding the earth (called greenhouse gases such as water v***r, carbon dioxide / CO2 and methane) so that the heat of the rays is trapped in the Earth's atmosphere.

This event is known as the Greenhouse Effect (ERK) because the event is the same as the greenhouse, where the incoming heat will be trapped inside it, unable to pe*****te the glass, thus warming the greenhouse.

This natural event causes the earth to be warm and fit to be occupied by humans, because if there is no Greenhouse Effect then the earth's surface temperature will be 33 degrees Celsius cooler.

All life on Earth depends on this greenhouse effect, because without it, the planet will be so cold that ice will cover the entire surface of the Earth.

However, if these gases become more excessive in the atmosphere and continue, consequently the warming of the earth will be excessive and will continue

The greenhouse effect, first proposed by Joseph Fourier in 1824, is the process of heating the surface of a celestial body (especially on a planet or satellite) caused by its composition and atmospheric state. Greenhouse Effects occur only on planets that have Earth-like layers, Mars, Venus, and Saturn's natural satellite (Titan).
