Help the Planet – Plant More Trees

There are a lot of people who are aware of the disastrous calamities and devastating catastrophes that is happening in our planet nowadays. Experts say that this is the result of climate change. And it is all caused by nonstop human activities like illegal logging, factories with excessive carbon dioxide emission, too much fishing and many more. These doings really affect the movement of the livings things around the Earth.


Hence, we all need to cooperate and plan to repair the planet. We need to plant more trees. It’s cliché. But when you do it, it is a great help knowing that planting trees can save the planet. Yes, trees can definitely help sip floodwater fast. Also, it can prevent flood and other disaster that is a great threat for humans.

Many woodcutter sees tree as an easy money but behind that, they do not know the exact uses of trees in the environment. One of that is that trees produces natural and fresh air. Now, they are just cutting down big trees, so what would you expect? Trees are not difficult to grow but it will take years or decades for it to become a fully-grown tree.


Now, if many loggers cut and cut trees without planting, for sure, we will all die. On the other hand, there are a lot of loggers claim that when they cut one tree, they will plants ten trees in return. But it is not as easy as that because not all seedlings planted will survive natural calamities and other destructive disasters.


Properties and Occurrence of Gold

Gold is a soft but dense bright yellow metal that has an atomic number of 79 in the periodic table of elements. Its symbol is Au which is derived from the Latin word aurum which literally means “gold”. It is one of the transition elements found in the periodic table. Pure gold is considered as the most ductile and malleable of all the metals that are currently known to man.



This means that it is very easy to draw it into a wire that is 62 miles or 100 kilometers long and hammer or beat it into a sheet that has a thickness of 0.000005 inches or 0.000013 centimeters and a weight of 12 oz or 29 grams. Gold is a good conductor of electricity and heat and is one of the softest metals (hardness rating of 2.5 to 3 out of 10) on Earth.


The metal has a high quality of sheen and is bright yellow in color. Like any other metallic powder, finely divided Gold is black in color. Gold powder that is suspended in a colloidal medium has a color that ranges from ruby red to purple. The metal is highly inactive.


Gold remains unaltered by heat, air, moisture and most existing solvents. Nonetheless, it will break down in aqueous mixtures that contain halogens such as bromides, chlorides and or a number of iodides. Gold also has a tendency to dissolve in a number of oxidizing mixtures such as aqua regia (which is a mixture of nitric and hydrochloric acids) and oxygen with cyanide ion.


The metal has a melting point of about 1947°F or 1064°C, a boiling point of around 5173°F or 2856°C, a specific gravity of 19.3 and an atomic weight of 196.97. Gold can be naturally found in secondary alluvial deposits and or in quartz veins either as a free metal or in a combined state. Even though the metal is considerably rare, being 75th in rank in terms of abundance of elements in the Earth’s crust, it is broadly dispersed throughout the world.


Gold is almost all the time associated with different amounts of silver (a naturally occurring gold and silver alloy is referred to as an electrum). Gold can also occur in chemical combinations with other elements and minerals. The metal has also been found in seawater to the extent of around 5 to 250 parts by weight to 100 million parts water.



Singapore’s Actions against Climate Change

Climate Change is the problem of all. All countries should address the issues of climate change for a cleaner and brighter future of its people. Countries are expected to do their part to minimize global concentrations of greenhouse gases. Every member of the international community should respond and be familiar with the impacts of climate change. Singapore for example is dedicated to take part in this global effort to battle climate change.


Here’s a quick look of Singapore’s actions against climate change:


There is UNFCCC (UN Framework Convention on Climate Change) which serves as the basis of governments to address climate change. UNFCCC have been campaigning to encourage international participation and action.

Kyoto Protocol

Singapore consented to the Kyoto Protocol in 2006. This is an agreement that seeks to reduce greenhouse gas (GHG) emissions by an average of 5%. It is said that this protocol is the first and important step towards a global reduction of emissions.


Singapore pledged to reduce its emissions by 16% below BAU (Business-as-Usual) levels in the year 2020. The pledge is legally binding.  Singapore pledged in the condition that other countries should do it as well.

International and regional co-operation

Singapore joined the talks hosted by international organizations like the World Trade Organization, World Intellectual Property Organisation, International Civil Aviation Organisation, etc. Singapore also discussed actions hosted by regional organizations like Asia-Pacific Economic Cooperation and Association of Southeast Asian Nations.

Aside from international engagements, Singapore is doing its best to implement national policies that can reduce emissions or climate change in general. Awareness of locals should be prioritized.

Singapore Construction Going Green

All contractors or construction companies here in Singapore that wants to bid or propose for public projects must stick to green standards provided by the BCA (Building and Construction Authority) by the end of 2016. Medium and large companies should be Green and Gracious Building Scheme certified so they can be included under the BCA’s registry.

The Green and Gracious Building Scheme is initiated by BCA that seeks to develop a sustainable environment. Many industries welcomed and accepted this initiative. At first, companies can voluntarily join but now, all companies are required to be certified. There are about three hundred firms that will be affected of this new policy or scheme.


The Green and Gracious Building Scheme together with the Green Mark Schemes seek to recognise the efforts of engineers, builders and architects in partaking to environmental protection. How can they partake in environmental protection? That is simple. The firms are encouraged to adopt energy saving steps and of course, lessen noise in the construction sites. At the end of the workers, they are encouraged to practice environmental friendly actions like recycling, reusing and reducing of materials, lessening of energy consumption and decreasing of water consumption.

The builders are asked to create their own policies and make sure to implement it.  Apart from creating and implementing of policies, the companies need to raise the awareness of their workers. Raising of awareness includes briefing sessions, in house assessment, green campaigns and many more. But everything will be in vain if the top management is not serious about its commitment to the environment.
