Bioremediation


We have already known that the environment is contaminated pollution since 2000 until now. The scientists tried to solve the environment problems by using bioremediation methods, why? It is because bioremediation is safe to the environment and humankind, lower cost, and also permanents to environment because it makes the contaminant degraded. Do you that Japan use phytoremediation methods to clean up the nuclear leak? Yes, phytoremediation is a part of bioremediation to clean up the nuclear leak. Phytoremediation method is cleaning up pollution through the use of plants and their microorganisms. In Japan, the scientists have still processed the phytoremediation by using a bamboo. They use this method because it is safe for the environment and can defect the global warming.

The population in this world has increased; therefore it creates more big problems. Like climate change, pollution, mutation, and chemical waste. The problems become worldwide; the estimated number of contaminated sites is significant. It is now widely recognized that contaminated land is a potential threat to human health, and it is continual discovery over recent years has led to international efforts to remedy many of these sites, either as a response to the risk of adverse health of environmental effect caused by contamination to enable the site to be redeveloped for use. One of the methods is to recover the environmental by using bioremediation process.

Bioremediation allows natural processes to clean up harmful chemicals in the environment. Microscopic “bugs” or microbes and fungi that live in soil and groundwater like to eat certain harmful chemical, such as those found in gasoline and oil spills. When microbes completely digest these chemicals, they change them into water and harmless gases such as carbon dioxide

The good idea is to use bioremediation to treat the environment which is contaminated with pollutants. Why? Because it is made a promising approach, such as, it would permanence, it is because contaminant was degraded, and it had potentially low cost, 60-90% less than other technologies.

8 principles of living things

My first day in college, my lecture of biology said the basic to learn biology was to know there’re 8 principles of living things.

Those are 8 principles of living things:

The first, the living things consist of chemicals, such as carbohydrate, lipid, protein, and nucleate acid.
Secondly, the living things consist of cell.
Thirdly, body of the living things has the structures which concerned with function.
The fourth is the existence of energy and other substances to live.
Fifth is biodiversity. The living things have unity in biodiversity and continuity. They have interacted to each others.
Sixth is homeostasis, the living things could defend on internal condition.
Seventh is living things could do a reproduction, because of genome.
The last, living things in this century that came from previous. They’ve have done a bio-evolution. Evolution happened because of the natural section. The nature had selected of people who could survive.
