Interrelationship among Population, Environment and Development

The environment is the source for human beings to receive what they need. Population growth, poverty and economic means and resources are not equal everywhere. In some places, people make the excessive use of natural resources. While carrying on development works, they should not forget the concept of sustainable development. They have to make development model considering the existence of human beings, environment and developmental activities.

The chart given below indicates the interrelation among population, environment and development.  

Interrelationship Among Population, Environment and Development

How Population, Environment and Development are Inter-related?

1. Use of Natural Resources: People must understand the importance of the interrelationship among various aspects of the environment. They use the natural resources in various ways. They make their house on land and obtain food by cultivating it. They bring wood, firewood, herbs, etc. from the forest. They get air and water from the environment. They can fulfill their needs if the interrelationship among the environmental aspects is well-retained. Population growth has caused the excessive exploitation of natural resources. They use land and water to increase production of food grains. Similarly, poverty, hunger, disease, illiteracy, etc. grow with the increase in population. The per capita use of natural resources also increases. If the expansion of population continues, natural resources cannot fulfill the demand of the people. 
2. Development and Construction Activities: Human beings conduct various development works to meet their aspirations. Development activities should be regularly conducted to satisfy the desire of the growing population. The conservation of the environment must not be stopped while conducting development works.
3. Economic Development: It is necessary to run various development activities like road construction, increase in agricultural production and industrial goods, exports of ready made goods and others for economic development. Such activities provide employment to the people and help to develop their working skills and performance. It leads the development of person, society and nation. Quality of life of people cannot be improved without development activities.
4. Socio-cultural Activities: Development activities include physical construction as well as socio-cultural development. People preserve, renovate and innovate their traditions and customs, religious places, temples and monasteries. These development works are related to social and cultural aspects. The preservation, promotion and development of these aspects support the people's cultural progress. The interrelationship among the development works, population and different aspects of the environment should always be managed. Development works must satisfy the need of the present generation without harming the requirement of the future generation.

Some more importance of biodiversity

1. Development of Tourism: The mountain, hill and the terai regions have their own types of natural environment and beauty. Different types of plants, trees, fruits, flowers, animals are found in these regions in these regions. Biodiversity is the root of this diversity. There are some important cultural heritages in various places creating beauty. The beauty spots have special importance for observation, study and research. They provide the background for tourism development. They attract to the native and the foreign tourists. The development of Eco-tourism helps the local people improve their economic status.
2. Economic Development: Biodiversity is the prominent source of food grain and medicinal herbs for survival and raw materials for industry. Development and use of herbs can contribute to the improvement of medical science. Biodiversity provides people different types of goods to conduct various activities. More organic goods can be produced by conserving and promoting biodiversity. Selling and distribution of such goods can support economic development.
3. Environmental Balance: Environment us related with multiple aspects. It is integrated to biological, natural, social, economic, physical aspects. These are related to human activities in social and cultural fields. Biological aspect is that which keeps the whole environment alive. With the disappearance or destruction of any aspect, the status of biological aspect of environment is distributed. Biodiversity is essential to maintain a balance in the environment.
4. Function of Natural Ecosystem: Biodiversity plays a significant role in the functioning of natural ecosystem. Different species are its integral part. It helps the natural process like water cycles, food-cycle, flow of energy, recycling of carbon, nitrogen, oxygen and other atmospheric gases. It also helps to balance temperature and maintain the fertility of soil. In this way, biodiversity plays an important role in the functioning of human life and other natural ecosystem.
5. Study and Research: Innovative knowledge and information are basic aspects for the development of biodiversity. Therefore, it is essential to conduct research and study on the different aspects of biodiversity for economic and  social development of human beings. The knowledge and skills which are acquired after the study and research should be used to preserve and promote the living organisms on the earth. Biodiversity is a wide area for research on the living beings. The research can be a great contribution to the welfare of human beings as well as other creatures of the world.

Relation between Health and Environment

Earth is our common home. It provides different resources such as air, water, food, soil, minerals, wood etc. Because of the growth of population, these resources are being used faster and faster haphazardly. Destruction of green forests causes landslides, erosion, flood, drought, etc. Urbanization and industrialization  cause air pollution.  Human being are responsible for deforestation and different types of pollution such as air, water, soil, noise etc.

Human beings and environment are closely related. Human beings depends upon environment for their survival because the environment fulfills their basic needs. We get food, air, water, etc. from the environment which are the basic necessities for our life. Fresh, healthy and proper environment has positive effects on our health and increases the longevity whereas the polluted environment has negative effect on our health and we suffer from different diseases. Thus, it is very essential to conserve our environment to promote our health.
