Overpopulation and its impact
A group of individuals of a particular species occupying a particular area at specific time is called as population. A species is a group of similar type of organisms that can interbreed under natural conditions. The interbreeding organisms of a species produce new organisms and finally result into the growth of population. This is true for all the life forms including human beings.
Underlying Causes of Loss of Biodiversity
Varieties of Biological Resources are in international demand today. To meet this international demand, illegal smuggling of these resources is done through illegal routes. Some species of plants and animals have been threatened, rare, endangered or critically endangered due to such practices. Several valuable species of plants and animals have become extinct due to these activities. The international trade in animal body parts is increasing rather rapidly due to their high prices in the international markets. Where possible, the trade of whole animals is also in full swing.
Sustainable Land Management and needs of this management
Land resources are used for a variety of purposes which may include organic agriculture, reforestation, water resource management and eco-tourism projects. In all these areas land use is needed to be sustainable.
Dahlia – One of The Amazing Flowers of winter
The first Dahlia flower in winter of the year was seen by me only today in my school garden. It looked so solitary, innocent and so beautiful that I could not resist the temptation of taking its photograph.
Various Important Alternatives to Deforestation
Deforestation contributes up to 20 percent of greenhouse gas emission which is more than the combined emission by all the cars, trucks, planes, boats and, trains of the world. Deforestation threatens our climate. Besides this, it threatens the livelihoods of 1.6 billion people who depend on forests for food and economic activities. They serve as habitats to rare and so far, undiscovered species of plants and animals. They also play a key role in maintaining water cycles and preventing floods and soil erosion. Hence, forests across the world need urgent measure of protection by all possible ways, may it be through alternatives to deforestation.
Biodiversity, Its Concept, Values, Loss, and Causes of Loss
An association of all the plants at a particular place is called a Plant Community and the association of all the animals at the same place is called an Animal Community. Both the plant and animal communities inhabit a particular place living completely merged and interacting among them. Members of a community not only interact with the members of other communities, they interact with the members of their community and with the physical environment around them, as well.
Ecosystem and its components
The total area where living beings are found is called as biosphere. It can be divided into many small independent units called as Ecosystem. In fact, the unit of biosphere which incorporates many types of microorganisms, plants and animals, physical factors like soil, water, air etc. interacting among themselves is called as ecosystem
Natural Resources and Their Types
Natural resources constitute both living and non-living resources. Non-living resources are renewable and non-renewable.
Mechanism of Breathing and Cellular Respiration
The mechanical process of breathing involves inspiration and expiration.
The route of environment problems and Sustainable World
The processes of development through years have spurred on unplanned urbanization, extensive industrialization followed by different types of pollutions, construction of a series of mega dams, and large-scale application of Agro-chemicals. In the process, different parts of the world have started facing ecological crises.
