Farming to Survive

farmingFarming is important

Currently you’re probably enjoying the food served in front of you, while in another hemisphere, someone is hungry grimaced. Ha, something that is not comfortable to read or hear isn’t it, especially at meal times. Well, talk about the food of course closely related to agriculture.

Every human life would require food. Back briefly to prehistoric times, people at that time to meet the needs of food by hunting or gathering fruit. Unfortunately, over time the amount of food provided by nature do not always meet the need. Then the human began to think to produce food, they begin to know how to raise livestock and farming.

Changes in farming systems

Humans continue to innovate to find the best ways to produce food. Many traditional farming systems using natural materials, and is also very dependent on the geographical location and season. It is a little more limiting agricultural products that can be produced.

In the early 20th century chemical fertilizers were introduced to the general public, the use of chemical fertilizers can shorten the time needed in the farming process, and cheaper. It can also significantly increase agricultural output. Comparing with traditional farming systems that process takes longer, more complicated and more expensive.

People prefer to use chemical fertilizers because it is cheaper and more produce. Besides by using chemical fertilizers they no longer need to deal with smelly and dirty traditional fertilizers. A mindset that should be straightened out by now.

Environmental pollution

‘s Been quite human aware of the problems that caused by the use of chemical fertilizers, but it is as if ignored for the sake of a handful of people. Chemical fertilizers work by manipulating the soil by adding nitrogen, potassium and phosphorus. The use of chemical fertilizers will continually contaminate the soil, making it lose fertility, so that the crops will depend entirely on chemical fertilizer.

Most of the residues of chemical fertilizers will be borne by farming irrigation systems, and pollute the environment along the water flow to the sea. In high levels, this pollution will damage the quality of the water and bring death to life in water. A real threat to the fisheries sector and the threat to the survival of living beings in general.

Use the ways of good farming
sustainable farming
Sustainable farming system is one viable method to be applied. This method guarantees a sustainable soil fertility, this is not something new because it has been practiced for thousands of years. This method focuses on organic farming methods, with seriousness and relentless innovation it will get farming products that do not disappoint.

Sustainable farming systems or organic farming is not only environmentally friendly, but also will improve the quality of human life in order to live more healthy. In addition to processing the soil is good and right, good crops can be obtained by breeding plant seeds.

It takes time to seeds breeding research, but it is worth doing for the sake of better farming system. That means that for the sake of a better life as well.

Water Contamination

fined waterBroadly speaking, water contamination can be defined as the deviation of the water properties of the normal state, or the purity of nature. This happens when water is heavily contaminated by remnants of sewage and waste.

Judging from the result, there are two kinds of pollutants that enter the waters. The first is that the material is toxic and damaging that can kill micro-organisms living in the water. The second is that materials enriching the waters, so that it can help stimulate the growth of micro-organisms and algae.

Water contamination can be classified into 3 types :
1. Contamination in physics, this pollution can be caused by floating material and buildup.
2. Chemical contamination, this pollution caused by hazardous substances, could be carbon compounds or inorganic compounds.
3. Biological contamination, this pollution caused by certain organisms such as pathogenic microbes, algae, or plants that could potentially carry the water hazard.

People often assume that the waste industry is the largest contributor to the occurrence of water contamination. Actually in quantity, industrial waste does not the biggest pollutants factor. Truly are the biggest pollutants factor comes from of everyday human activities, such as household waste, agricultural waste, stock husbandry waste, fishery waste, transportation, etc..
water contamination
For example, household waste is discharged into the river can disrupt the microbial life in the water, resulting in a decrease in the quantity and quality of aquatic biota. Remnants of water-soluble fertilizers can also fertilize aquatic plants that trigger the silting of the river or lake. Result of erosion and mud carried down to the sea will sink, and cover the surface of coral reefs, causing the death of coral reefs.

Currently waste from industrial activities can be said to have brought a serious threat to water contamination. Although many industries are implementing advanced technologies in waste water treatment, but still there are industries with no qualified industrial waste water treatment standards. It is very unfortunate, the regulations have been made, but there are still those who violate them.
water contamination
Waste from industry-which does not meet these standards provide a serious threat to the entire ecosystem. Because through natural mechanisms such as wind, water flow, and the movement of soil, the diffusion of the waste can spread quickly everywhere.

Need to build a collective consciousness to prevent water contamination. Not easy, but not impossible to achieve. Humans should be fully aware of the importance of water for life.
