Biodiversity and Ecosystem
This fundamental ecosystem function has relevance for global food supply and for primary production. There is currently great concern about the stability of both natural and human-managed ecosystems. It can be used to describe biological diversity at a variety of different scales. Species play essential roles in ecosystems, so local and global species losses could threaten the stability of the ecosystem services on which humans depend. It is often understood in terms of the wide variety of plants, animals and microorganisms including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them and provides information about the benefits of ecosystems and how we can use Earth’s resources in ways that leave the environment healthy for future generations.
Plants and Animal Biodiversity
Animals have adapted to survive and thrive in their environmental riches. Is one of the most fascinating aspects of biology? Farm animal biodiversity is so important for maintaining genetically diverse and healthy livestock. However, this diversity is being threatened by some industrial farming operations that depend on a small number of farm animal breeds that can thrive in an intensive livestock environment. Because of this, farm animal breeds that don't thrive in factory farming operations are becoming rarer. Plants species consists of familiar organisms such as trees, herbs, bushes, grasses, ferns and mosses.
Shortage of landfill sites, pollution, the depletion of the ozone layer, and the greenhouse effect challenge human existence. Some adaptations are behavioural and sometimes behavior drives the evolution of new adaptations by creating new selective environments. If an organism has a trait that provides an adaptive significance in its environment, then natural selection favours it. Adaptive significance refers to the expression of a trait that affects fitness, measured by an individual's reproductive success.
Coastal & Marine Biodiversity
We people need air to breathe, water to drink, food to eat, new medicines, a climate we can live in, beauty, inspiration and recreation. As we know that living oceans absorb carbon dioxide from the atmosphere and reduce climate change impacts. The diversity and productivity of the world's oceans is a vital interest for human kind marine species provide important ecosystem services such as the provision of food, medicines, and livelihoods. They also support tourism, recreational and many other activities around the world. Unfortunately, the resources of the sea have been over-harvested by humans, threatening marine biodiversity and we should think on it.
All types of life, regardless of whether microorganism, plants, people contain genes. It is nothing but the sum of genetic information contained in the individual plants, animals and microorganism. Important conservation consequence of this is even an endangered species is saved from extinction.
It aims on economy that aims at reducing environmental risks and ecological scarcity and its main focus is for sustainable development without degrading the environment.
Forestry is nothing but the science and craft of creating, using, managing, repairing woodlands, and associated resources for human and environmental benefits. If we talk about economic segment then forestry plays an important role in various industrial countries. For example, if we talk about Germany, then forests cover nearly a third of the land area, wood is the most important renewable resource, and forestry supports more than a million jobs and nearly about €181 billion of value to the German economy each year.
Environmental Toxicology is about the study of the effect of the man-made and natural chemicals on health and the environment. It includes the study of the effect of chemical on organism.
It is the study of insects and their relationship to human, environment and other organism. And entomologists make great contributions to such diverse field such as agriculture, chemistry, biology etc. Entomologists makes contributions to such diverse field as agriculture, chemistry, biology, human or animal health, molecular science and forensics. The study of insects serves as the basis for developments in biological and chemical pest control, pharmaceuticals, food production and storage, mapping biological diversity, robotics and other field of science.
It is a process of maintaining plants or animals, in a controlled environment, Like zoos, botanical garden. It also used for saving species from extinction. It is sometimes employed to help species that are being threatened by human activities such as human loss, fragmentation, over hunting or fishing, pollution, predation, disease and parasitism. But for success breeders must consider many factors including genetic, ecological, behavioural and ethical issues. Most successful attempts involve the cooperation and coordination of many institutions.
Biodiversity management is nothing but it’s a type of management which can be done by managing the sustainable forest and harvesting Trees, and the ecological restoration.
