Ocean is a vast natural resource of water. These have also been examined in the search for alternate sources of energy-generation. For example, gravitational pull, by sun and moon causes tides, in which sea level rises and falls, two times in 24 hours. When it rises, sea water may be diverted through suitable channels, to inshore reservoirs driving the turbines, during its entry.
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.
Human activities have never been friendly to environment. The remains of Mohenjo-Daro and Harappa signify that the civilization ended due to desertification which might had been caused by large scale deforestation. Still today impacts of such human activities have started appearing. Hence it is essential that we manage our natural resources properly.
A forest is a highly complex and constantly changing environment. It is made up of a variety of living things like wildlife, trees, shrubs, wildflowers, ferns, mosses, lichens, fungi and microscopic soil organisms; and non-living things such as water, nutrients, rocks, sunlight and air. Trees are the biggest part of this complex community.

Mixing of different solid, liquid or gaseous substances and microorganisms into water, so as to alter its natural qualities is called as water pollution. According to the National Water Commission (1973), water gets polluted if it has not been of sufficiently high quality to be suitable for the highest uses people wish to make of it at present or in future.
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.
Though there are two basic types of leaves of monocotyledonous and dicotyledonous plants, we observe immense diversities in their arrangements, sizes, and shapes.
Some leaves are very short, as short as they cannot be seen through naked eyes where as there are big broad leaves that can form many umbrellas for small children.
Due to less paying agriculture farmers migrated to cities. The volume of migration was seen during the lock down period when farmers left cites for remigation. Remigrated farmers can be checked to their fields by improving pricing and free maket system to farmers.
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.
The environment has two basic components: Biotic and Abiotic. The biotic components of an ecosystem are living beings—plants, animals, and…
