Biome is a collection of biological population of different species living together in a space defined and we have a close relationship.
 Biomes are a way to divide the Earth's surface. These divisions are based on climate pattern, soil types, the animals and the plants that inhabit an area. There is a biome on dry land and in water. Every inch of the Earth's surface is apart of one or more biomes.
There are a couple of different ways to look at the number of biomes. Some like to divide into five basic types:  aquatic, desert, forest, tundra and grassland.
Biome is a complex biotic community characterized by distinctive plant and animal species and maintained under the climatic conditions of the region, especially such a community that has developed to climax.

• Predict if Vietnam can sustainably feed it’s future population:

 World population is expected to grow by over a third, or 2.3 billion people, between 2009 and 2050. If people work hard to feed themselves, Vietnam's population will grow in the future. In 2016, Vietnam's population is 93,421,,835 people. In the future Vietnam's population will increase quickly, so people in Vietnam need to work hard to feed themselves in the future.  In addition, the reproductive rate of Vietnam is increasing very fast. So if Vienamese people do not work hard, they will suffer from hunger in the future. People need do process the food to eat  in the future.

Describe one challenge to food production in Vietnam:

• Climate change is happening, the greater challenge for humanity on food security and poverty. People can be hungry due to drought, floods, and falling into poverty. Our agricultural production is excessive not because the markets do not need the products but because we do not produce the new products that the market requires. The situation is ore difficult through the appearance of new agricultural exporters. They are competing hardly with us in our traditional markets.
• Severe weather changes constantly. Production level is backward, people are not aware of  the important part of food production in our country. They unknown application of scientific advances in the production techniques.

• . What is something you can do every day to protect Vietnam’s environment? You need to protect the environment by yourself. People need to be aware to protect the environment. people are not littering. People do not use the plastic, instead of using some recycle things to cover. In addition, water pollution from the factories is very serious, they need to filter wastewater before it is discharged into rivers, lakes and sea.
If you want to protect the environment, you must keep the tree. Moreover, the paper is maken by the wood, so you have to save the paper.
