Discoveries and inventions have made human lives easy and comfortable. Men have stopped walking long distances. But his does not relate to flying of birds. They continue flying and flying for ages very high and up to amazingly long distances.
Our natural resources are known to have some specific qualities of their own. These qualities are known as natural qualities. It is due to specific natural qualities that different natural resources have been useful to us and to the whole biosphere. But now, the condition has changed considerably. Most of our natural resources like air, water and soil have gone bad due to pollution of different types. What is pollution?
Our environment today is facing a number of problems. All those problems are causing dangers to take shape against the existence of the whole biosphere of this planet. But who is behind all those problems? The answer is – M A N.
Most animals of the same kind have same body parts. But their body parts differ in size, shape, colour and functions.
The balance of nature is maintained by its different components -living and non-living, if they remain unaltered by human beings.
The predominant features that create structural complexity in the environment, such as plants or animals are called as a habitat.
A process, in which natural habitat is rendered functionally unable to support the plants and animals occupying it, is named as Habitat destruction. In the process of habitat destruction, plants and animals that previously used the place are displaced or destroyed, reducing biodiversity.
All those processes that maintain the body of an organism collectively are called as life processes. These processes principally include Nutrition, Respiration, Internal Transport, and Excretion. Some other processes of life like control and coordination, Reproduction, Heredity and Evolution etc. are essentially found in living beings but they are not directly related to processes of life. Hence, these may or may not be regarded as life processes
Forests and wildlife are integral part of environment. Forests control climate, soil erosion and wildlife. They cause rains.
There are various uses of Solar Energy. Farmers in Traditional Farming Communities used to solarise fields by living them empty after a deep ploughing during summers. It killed insects and pests. Human skin synthesizes vitamin-D when exposed to sunlight for short durations. Mothers used to make their babies sleep in the sun after oiling their bodies during winters in order to keep them healthy and strong.
The biosphere has been composed of a number of highly complex ecosystems such as forests, grasslands, oceans, estuaries, deserts etc. These ecosystems have gone under threat over the years due to intensive human pressure of serious pollutions, habitats destructions, land, water bodies, wetlands and coastal zones reclamations and so on.
Many people are working longer and harder, thinking that this will solve the problem of an ever-increasing workload. But they are still falling behind, becoming chronically overwhelmed, and burning out.
Human beings needed to live together to have a family and to rear and develop children. They lived together for social security and social strength. Thus, human settlements were formed.
Neighbourhood is a geographically localized community within an area, may it be a rural area, a town or a city, or sub-urban.
