Biology

If my parents are going to build a second home, I would suggest building one in a mountainous region, preferably on a mountain that has relatively lesser trees and stronger winds. Provided that there are no budget and resource constraints, I would like to propose some ideas to make the house as sustainable as possible.
I would propose building a solar panel on the roof of the house, as well as a windmill nearby. Both wind and solar energy are known for their variability, and so constructing both a solar panel and a windmill would guarantee an almost constant supply of power. Implementing these sustainable sources of energy would cause lesser pollution by lessening the energy consumption from power plants generating electricity through the utilization of fossil fuels. 
For exterior construction materials, I would recommend the use of sustainable materials such as Hemcrete and Papercrete. These are concrete made from paper and other fibrous materials, and would help reduce un-recycled textile and fiber waste. I would also encourage the use of fly ash to serve as additive to cement. This would help recycle fly ash, as well as lessen global energy consumption for mining and heating limestone in order to produce cement. Moreover, I would suggest reusing unneeded construction materials should it be possible to procure them. Reusing construction materials is both inexpensive and sustainable.
I would advice the use of X-board for both indoor construction and furniture. X-board is a construction material made from recycled honeycomb. Unlike medium density fiberboards or plywood, X-boards primary material is not derived from wood, and is not processed using formaldehyde, thus lessening indoor pollution and reducing our dependence on trees (Grigsby 2009).
Household wastes should be addressed accordingly. Biodegradable solid waste should be put on a compost pit to serve as fertilizer to a nearby home garden. On the other hand, liquid sewage waste would be subjected to an aeration system so it can be treated and be used to water plants. On the other hand, non-biodegradable wastes would have to be segregated and delivered to the appropriate recycling facility. Implementing these would reduce environmental impact and minimize the carbon footprint of household products used.

CAUSES OF GREENHOUSE EFFECT
The following are some human activities that contribute to the concentration levels of atmospheric greenhouse gases.

Utilization of Fossil Fuels
Use of Aerosols and CFCs
Industrial and Electrical Generation
Agricultural Processes
Deforestation and Clearing of Land

The first four causes mentioned results to an increased concentration of greenhouse gases, primarily due to their atmospheric emissions. On the other hand, the deforestation and clearing of land indirectly affect the concentration of greenhouse gas by disrupting the role of plants in the oxygen cycle.

OUR MORAL IMPERATIVE ACCORDING TO AL GORE
Gores documentary titled An Inconvenient Truth demonstrated that some human activities are responsible for the increasing levels of concentration of greenhouse gases in the atmosphere, and thus causing global catastrophes such as rising sea levels, global warming, and climate change. It urges its viewers and readers that stopping global warming is our moral obligation. However, addressing this concern would impose grave restrictions to industrial development among nations and business organizations. Therefore, the said documentary appealed that although the fight against global warming may be inconvenient to most people, it urges everyone to participate because it is a moral imperative. It persuades every reader and viewer to do the right thing stop global warming and conserve the environment.

THE INCINERATION OF MUNICIPAL WASTE
Incineration is a waste management method that involves the combustion of waste. An incineration plant uses a combustion chamber in order to burn solid waste. The following are the advantages and disadvantages of the use of fossil fuels

Advantages
Incineration Plants Require Less Land. Compared to other waste management methods and facilities, an incineration plant needs relatively less land to operate.

Unaffected by Weather Conditions. Other waste treatment methods such cpen dumps and ocean dumping cannot operate effectively during a harsh weather. On the other hand, an incineration plant can operate smoothly regardless of the weather.

Odor-Free Residue. Unlike Other treatment methods, incineration would reduce solid waste to ashes, leaving an odor-free residue. This residue can then be disposed using the other waste management methods.

Disadvantages
Cost. The construction and maintenance of an incineration plant are expensive.

Requires skilled workers to operate. Unlike other systems, an incineration plant requires skilled personnel to facilitate the disposal of the waste from combustion to disposal. Incineration is a hazardous procedure and also requires strict and steady maintenance.

Emissions. An incineration plant uses combustion to burn municipal waste, thus resulting to atmospheric emissions. These emissions may cause other environmental problems. Due to this, such plants need to be situated in less populated areas.
