Human activities in the environment.

 

Human activities in the environment;

These are daily routine human beings do everyday.

 They can also be things human beings make every day.

Some of them are useful to the environment and others are harmful.

Among those which  are harmful we we have what deforestation, mining and charcoal burning.

Human activities that are useful to the environment include ;afforestation ,terracing ,mulching and crop protection.

Important human activities;

Afforestation;

This is the planting of trees in places where there is scarse vegetation.

It can also be the growing of crops in places where there is less vegetation.

Corporation;

This is the growing of different types of crops on the same piece of land season after season.

This  help to control soil erosion and mass wasting.

Mulching;

This is the covering of soil with dry grass or leaves.

Is mainly carried out to prevent soil erosion and other forms of mass wasting.

Terracing;

This is the making of trenches especially in hilly  and mountainous areas.

They help to control soil erosion through reducing the speed of running water.

The small treches  are called terraces.

They retain water which is rain water and reduce its speed.

All the above a human activities that are useful to the environment.

Activities that are dangerous to the environment;

Bush burning;

This is the burning of bushes especially in dry season.

It is always done by mere people who even don't know what they are doing.

Some are smokers and others do it intesionary just burn the environment.

Deforestation;

This is the massive  cut down of trees in a given area for both wood fuel and sometimes electric poles.

It is even worse when these trees are cut and not and not repressed.

Industrialization;

This is the setting up of industries in a different area.

The cutting of trees in  search of land where to set up the industries.

This is also dangerous to the environment. We encourage people carry out useful activities to the environment.

Improper disposal of human wastes;

This is an activity done by the people in the community.

Some people tend to misuse this activity by disposing human works like 5 years into what a body.

They slow these human wastes with in the water bodies like, lakes and the rivers.

Over cultivation;

This is the cultivation done on a large piece of land in the environment.

This leaves the land bear and exposes soil to erosion agents.

Mining;

This is the extraction of minerals from underground.

It is always carried out on the Earth's surface after vacation cover have been created.

When land is left bear, this leads to soil erosion and mass wasting.

Types of human activities in the environment;

We have main five types of human activities in the environment.

They include the following; primary human activities, second grade human activities, tertiary human activities ,quaternary human activities and quinary human activities.

Primary human activities;

These are activities that can be done by even young people below  the age of 10 years.

This include; washing utensils ,washing clothes, fetching water and collecting fire wood.

Secondary human activities;

These are activities that are done by people below the age of 18 years.

They include; correcting files ,digging and reading some heavy books.

These activities need some energy and without energy they can't be done.

Tersiary human activities;

These are activities that need energy and require some tools like hoes, axes and pangas.

The include; building ,slashing the compound and weaving.

Outcomes of human activities to the environment;

Some like deforestation cause soil erosion. This is dangerous to the environment in that it causes soil leaching.

 They cause climate change in the environment especially Bush burning.

They cause the denature of the environment especially mining.

They cause suffocation of animals which live in the bush especially Bush buning.

They cause what production in agriculture.

Types of pollution caused by human activities in the environment;

Water pollution due to the improper disposal of human wastes.

Air pollution in the environment because of industry fumes.

This can also becaused  by excess carbon dioxide in the air.

Light pollution caused by large barriers in the environment.
