Hello, my name is Alexander and I'm currently working on environmental pollution problems at a timber floating.

My research aims to study problems at a timber floating and to reduce pollution of the rivers and environment.

This is useful, because we have to keep the nature for future generations.

For example, the substances extracted from wood decay in water, absorbing oxygen, causing death of fishes. Also bark, boughs, branches litter a bottom of rivers.

However, there are obstacles to the studying this problem. These include the lack of funds for the practical test, the limited research base and the limited time available to conduct the research.
