In India, a Hazardous Substances Management Division has been constituted as a nodal point within the Ministry of Environment and Forest. This nodal agency is responsible for Planning, over-seeing and implementing the policies and programmes on management of hazardous substances and Chemical Emergencies.
There are many different types of technologies or technological models- such as Low-tech, Hi-tech, alternative, intermediate, appropriate, blended, hard, and soft technologies.
Brain and Spinal cord together constitute the Nervous System. The nervous system receives information in the form of impulses from all parts of the body and integrates this information.
Land management is the process of managing the use and development of land resources in rural and urban areas. Land resources are used for a variety of purposes which may include organic agriculture, reforestation, water resource management and eco-tourism projects.
Conservation of the environment implies the sustainable use and management of natural resources, including wildlife, water, air, and soils.
Darwin published his book “On the Origin of Species” on 24 November 1859. The aim of Darwin Day inspires to fulfil the academic curiosities. It demands to search the truth in scientific ways.
According to their physical make up, there are basically two types of animals- Vertebrates and invertebrates. Invertebrates are those animals that don’t have a vertebral column or backbone. On the other hand, Vertebrates are those animals who have a vertebral column or the back bone.
Ecosystems can be categorised into two broad categories: natural and artificial. Natural Ecosystems are those ecosystems that operate by themselves under natural conditions. These ecosystems are further categorized as Terrestrial and Aquatic Ecosystems. Terrestrial ecosystems relate to lands, whereas Aquatic ecosystems relate to fresh or marine water. Freshwater ecosystems may be Lotic or Lentic. Lotic are running water ecosystems like springs, streams or rivers, whereas Lentic Fresh Water Ecosystems may be found in standing waters of lakes, ponds, pools, puddles, ditches, swamps, etc. Marine Ecosystems are found in marine waters of salt lakes, seas, oceans and estuaries. Artificial Ecosystems are man-engineered ecosystems like crop fields, artificial ponds and lakes, aquaria, fish ponds, and abandoned mines reclaimed as lakes or water bodies for recreation.
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.
Ozone absorbs ultraviolet radiations so that much of it is never allowed to reach to the earth surface. The protective umbrella of ozone layer in the stratosphere protects the earth from harmful ultraviolet radiations. Ozone plays an important role in the biology and climatology on the earth’s environment. It filters out all the radiations that remain below 3000Å. Radiations below this wavelength are biologically harmful. Hence any depletion of ozone layer is sure to exert catastrophic impacts on life in the biosphere.
The application of scientific knowledge for practical purposes, especially in industry, is called as technology.
