Biodegradable Plastics


Biodegradable plastic is plastic that decomposes naturally in the environment. Biodegradable depicts a chemical process during which micro-organisms that are available in the environment convert materials into natural substances such as water, carbon dioxide and compost. 

Making Biodegradable Plastic:
Biodegradable plastics are made from all-natural plant materials.
These can include corn oil, orange peels, starch, and plants. Traditional plastic is made with chemical fillers that can be harmful to the environment when released when the plastic is melted down. With biodegradable plastic, you get a substance made from natural sources that does not contain these chemical fillers, and does not pose the same risk to the environment.The process of making biodegradable plastics begins with the melting down of all the materials.    

Regular Plastic vs. Biodegradable Plastic

1. Regular plastics hold carbon. When they are disposed of and begin to decompose or when they are melted, that carbon is then released into the atmosphere. Biodegradable plastics do not release carbon, because no carbon is involved in the manufacturing process.

2. One of the many positive aspects of biodegradable plastics is that they are able to be broken down by naturally occurring bacteria, which again will be beneficial to the environment.

Biodegradable plastics do have some drawbacks.They do not decompose unless they are disposed of properly, meaning that biodegradable plastics must be treated similarly to compost. These plastics do not contain the harmful chemicals and materials that traditional plastics do.

HOW TO MAKE BIODEGRADABLE PLASTIC:
Matrieals:
Cron starch
Water
Cooking oil

Tools:
Spoon/Something to measure with
Microwave container
Microwave

Step2:
1 tbsp cron starch : 1.5 tbsp water : 3 to 5 Drops cooking oil

Step3:
Mix the ingredients together to form a milky looking liquid. Once you have done this is ready to microwave.

Step 4: Put mixture in the microwave on high 25 to 30 sec.  When it look transperent slightly take it out. Let it cool be so you can handel it.then mold it into whatever shape.  Once molded leave it for 24 hours. For it cure and become solid.

You can use food colouring for plastic some colour.

You can use it for plant indoors.

Deforestation effect on wildlife

Deforestation causes wild animals to loose their natural habitats. This results in shortage of food for the wild animals, which in turn reduces their numbers due to death, caused by starving.

Importance of trees in our life

Let's Plant more trees to save Earth Trees provide oxygen. They play an important role in the ecology system. Ecological imbalance can cause flood  and various other natural calamities that can lead to destruction of life from this earth. Therefore it’s important that we save the trees we have in order to maintain ecological balance and we should also plant more and more trees to save earth. "One touch of nature makes the whole world kin." ― William Shakespeare "The creation of a thousand forests is in one acorn." ― Ralph Waldo Emerson "Love the trees until their leaves fall off, then encourage them to try again next year." ― Chad Sugg "Whoever has learned how to listen to trees no longer wants to be a tree. He wants to be nothing except what he is. That is home. That is happiness." ― Herman Hesse "The care of the Earth is our most ancient and most worthy, and after all, our most pleasing responsibilit...

Land Degradation Cause & Prevention's

Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. Land degradation occurs when the economic and biological productivity of land is lost, primarily through human activities.   Land Degradation Major Causes: 1. Deforestation : Deforestation cause due to  increasing demands of fuel and forest products which results into degradation of land resources. 2.   Agricultural Practices : The modern agricultural system uses excessive  fertilizers and pesticides has adversely degraded the natural quality and fertility of the cultivation land. 3. Industrialization: Rapid growth industries of the country leads to excessive deforestation and utilization of land in such as way that it has lost its natural up gradation quality. 4. Urbanization: One of the main reason land degradation is increasing growth of population demand for more residential areas...
