Bioinvasion of Foreign and Genetically Engineered Species
An incident of invasion by a living species into entirely new habitat thereby threatening the existence of native species is called as bioinvasion or Biological Invasion.

Marine Pollution and Oil Spills
It is due to frequent oil spills that sea otters, many sea birds, whales and many other species of the marine environment have become endangered. The oil spill damages fisheries and Mari culture, and causes serious economic losses to the local public and the governments.
Genetic Diversity Erosion: Causes and Impacts
Different types of plants and animals have been blessed with peculiar and important merits. These merits are expressed in plants and animals due to specific genes found in them.
Dynamics of Population
A population is a group of individuals (all members of a single species) who live together in the same habitat and are likely to interbreed. Each population has a unique physical distribution in time and space. It may contain individuals of different ages, and its size (density) is likely to change over time. It grows or shrinks according to the reproductive success of its members.
Some Types of Technologies
There are many different types of technologies or technological models- such as Low-tech, Hi-tech, alternative, intermediate, appropriate, blended, hard, and soft technologies.
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.
The Garbage Clinic- An Innovation- The story of in campus waste treatment, by Egg. Students of CCSU, Meerut, India
Students of the Department of Engineering in Chowdhari Charan Singh University, Meerut,India, have developed specific unit to process the in campus waste and turn it into manure. The garbage treatment Unit is called as Garbage Clinic by them.
Grow Banyan and Tamarind for a better environment
Both the banyan and tamarind trees have large canopy and plenty of leaves. These produce lots of oxygen and absorb lots of carbon dioxide. Thus, besides numerous other benefits they keep up the balance of environment.
Plants that survive under hardships
Many ferns grow along north or west facing walls every year. Their spores might have been there in crevices during the dry season. Unless there is a supply of water from leaking pipe they complete their life cycle within the rainy season and pack up with the passing rains. They pass away and leave for us a lesson to remain happy and survive in hard conditions.
Exotic and Introduced Plants
Some propagules or seeds incidentally travel long distances and reach to other county. There they germinate and produce new plants.
Plant Trees to Compensate Loss of Oxygen
The scarcity of oxygen and the need of producing more and more oxygen! We may think for sometime about it. But, anyone knows that life is not possible without it.
All about wind energy
The Wind is Air in Motion. It is caused by differential heating of land, water, hills and mountain slopes by sun rays. About 25 % (i.e., 0.34 KW/m2) of incident solar radiation is dissipated as wind energy. There is kinetic energy in wind.
