Biodiversity is defined as the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic Ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species, and of ecosystems. Basically biodiversity is the total number of genes, species and ecosystems of a region. It includes … Read more
The Greenhouse Effect The greenhouse effect is a natural phenomenon that insulates the Earth . Incoming solar radiations are absorbed and reemitted back from the Earth’s surface as infrared energy, greenhouse gases (GHGs) in the Atmosphere prevent some of this heat from escaping into space, instead reflecting the energy back to further warm the surface. Human … Read more

Biodiversity-Defination, types, importance, hotspots, threats and conservation The term biodiversity was coined as a contraction of biological diversity by E.O. Wilson in 1985. Biodiversity may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. In other words, biodiversity is the occurrence of different types … Read more

Ozone (O3) is a molecule made up of three atoms of Oxygen (O), and is mostly found in the strato- sphere, where it protects us from the Sun’s harmful ultraviolet (UV) radiation. Although it represents only a tiny fraction of the Atmosphere, ozone is crucial for life on Earth. The stratospheric ozone layer forms a … Read more
