Why Sustainable Agriculture

You are not eating real food every day. This is not a question, this is a statement. What, I am off my mind? No, I am certainly not. If you think I am talking nonsense, then you need more reading on “industrial agriculture” and “sustainable agriculture”, dear reader.

Industrial Agriculture
Basically, this is a way to produce modern food by using industrial methods.  Industrial agriculture is sometimes considered one of humans’ greatest successes. It has had large, complicated effects on our environment, our economy, and of course, our health problems. (1)
Completely cheap meat.

Sustainable Agriculture
This is agriculture practices purposely preserving environmental integrity, foster integrate farming communities. It is a new method trying to increase farm profitability based on diversified activities. (2)
Not only a beautiful picture, but also where our food grow.
Obviously the second method, sustainable agriculture sounds a lot better than industrial agriculture.

Food is essential for healthy growth and development, and industrialized food may have many negative consequences because “you are what you eat.” There is no way for you to grow naturally while eating food full of chemicals and unsanitary conditions.  Chemicals commonly used in industrial agriculture are pesticides, insecticides, herbicides, fungicides, and antimicrobials. (3) These chemicals may not all seem familiar to you, but they can easily cause endocrine disruptions and cancer in humans. The excessive use of antibiotics is another practice used to keep livestock healthy, but it contributes to antibiotic resistance among humans. (3)
If you are strong enough, you won't get sick...immediately.
If you are thinking maybe you can simply choose to not eat industrialized food and grow vegetables in your backyard, then please take a look at the environment around you. The environmental burdens from industrial agriculture are monoculture production, toxic herbicides, insecticides, and chemical fertilizers accumulate in the water and pollute water supplies. Massive amounts of fecal waste create toxic chemicals in manure holding pits seeping poisons into the soil and air near our water and food sources which cause streams, rivers, and groundwater to gather pollutants. (3)
This is what we have to eat? You have a choice to say no!

Scared by these facts already? No worries, let’s move on to the solution of this problem – sustainable agriculture.

 As already mentioned, sustainable agriculture raises food that is healthy for humans and animals. The magazine National Geographic states that, “The concept of sustainable agriculture embraces a wide range of techniques, including organic, free-range, low-input, holistic, and biodynamic.(5)” Land and natural resources such as water, soil and air can be replenished and ready to be used by future generations. (4) Farms raise various types of crops and animals. And all livestock are treated with respect. (4)
Different types of animals grow in the farm.

Even though industrialized food seems to be much cheaper than natural food, however, we have to think this way: healing illness cost a lot more than healthy food. I don’t think we are one hundred percent safe from industrial food even in nowadays, but I do believe things are getting better since there are more and more people being aware of this issue. Overall, sustainable agriculture is definitely the right choice.

Designer babies - blue eyes are on sale today?

Design your own baby?


Many wealthy people enjoy wearing outfits which designed especially for them in nowadays. However, did you ever hear about design your own baby? A designer baby is an infant controlled by genetic engineering combined with in vitro fertilization to choose the absence or presence of a particular gene. In another word, this technology allowed parents to custom build their children. Within advances in genetics research, people may soon preselect their children's physical and personality traits just like pick out clothing materials and styles.

Technologies Involved

In vitro fertilisation or IVF is one of the advanced reproductive techniques. It has been used to fertilise eggs with sperm in to a laboratory condition. Scientists therefore have had a chance to observe, modify and change genes under microscopes. Theoretically, we may also be able to "cure" diseases in embryos by replacing faulty sections of DNA with healthy DNA in the future. This practice is called germ line therapy. Such therapy is still illegal to be tested on humans, but successfully been done on animal embryos.



What is Legal

There are only two types of legal advanced reproductive technologies on humans right now. One of them is choosing the sex and genes of the baby by selecting a sperm that will fertilise an egg. The other one is Pre-implantation Genetic Diagnosis (PGD), which is a technique screens particular embryos to put in the mother’s womb.


Ethical Considerations

After the news on designer babies was revealed, many people were surprised. Soon we need to face problems such as what is moral limit to create a baby. The whole idea can be indentified into two kinds of motivation: preventing disease and enhancing attributes.

In the year of 2003, a genetically designed baby was born with stem cells from the umbilical cord would be used to treat a blood disorder in his older brother. The ethical issue followed up immediately was that the boy was born without any dignity of life. Clearly, his life purpose was pre-decided to save his older brother, created to be a medical tool.

The human race must stop trying to play God by messing with genetics and embryo alterations. We should feel guilty for daring to control a person’s free will; nobody has the right to decide the unborn child’s any traits.

Conservation on Biological Diversity and Green Wave

The Word: Definition for Biodiversity
noun The existence of a wide variety of plant and animal species in their natural environments, which directly relates to the productivity of the ecosystem.

The problem: Who cares biodiversity?

The problem is that many animals are dying because of loss of habitats which is caused by human interactions such as deforestation, over population, global warming, and pollution.

Humans are surly affected by biodiversity because a simple theory:
No animals (plants) =no food=no humans.

The organization: Convention on Biological Diversity (CBD)

Logos used in CBD’s website.
The United Nations Environment Programme (UNEP) convened the Ad Hoc Working Group of Experts on Biological Diversity in November 1988.  The experts in this group were to take into account "the need to share costs and benefits between developed and developing countries" as well as "ways and means to support innovation by local people". On 22 May 1992, the group adopted a new name: The Convention on Biological Diversity (CBD) with the Nairobi Conference.
CBD entered into force on 29 December 1993. It has 3 main objectives:
1.      The conservation of biological diversity
2.      The sustainable use of the components of biological diversity
3.      The fair and equitable sharing of the benefits arising out of the utilization of genetic resources
The event: one of CBD’s contribution to biodiversity
Green Wave

High school students producing
“green wave”.



The Green Wave is a global biodiversity campaign to educate children and youth about biodiversity run by the Convention on Biological Diversity. Each year, The Green Wave will contribute to worldwide celebrations of the International Day for Biological Diversity (IDB) mostly by planning trees. The United Nations has designated 2010 the International Year of Biodiversity. Leading aircraft manufacturer Airbus is proud to be working with CBD as partners.
In participating schools, students plant an important tree species of their local area in the schoolyard. Students from all around the world will count down to 22 May 10:00 local time altogether and then plant their tree from the east travelling to the west of the Earth.
The purpose if this yearly event since 2008 is to engage and educate young people worldwide about the crucial role biodiversity. It is also a campaign to raise awareness in children and youth.

Conclusion: Editor’s Feedback:
Finally, this biodiversity problem-to-solution breakdown is over. However, there are so many more environmental problems still affecting our lives. We have been live in Toronto, Canada every day and it is easy to think that the Earth is pretty okay. This is a myth! I have seen cities without any trees in other countries, just like some parts in downtown. When I read the Green Wave project, I remembered I could even breath the dirt in the air when I was in a city full of buildings, then I decided to research on this topic. This year, I joined Green Quest; we seem to have an opportunity to go planting. I am really looking forward to take an action.
