Biodiversity

1) Provide two examples of human activities that alter biodiversity and explain. In general species alter biodiversity one of the example of human activity is the land use change. Human transformed a percentage between 40-50 of the ice-free land surface and also also changing prairies, forest and wetland into agricultural and urban system. The other example is by adding a species to the population and that has effect to other species in the area. 2) Why is it important to take species evenness

Biodiversity is essential for the survival of mankind and the environment for many reasons. The loss of biodiversity is a growing epidemic in Canada, as thousands of species are starting to diminish in number to the peak of extinction. According to Merriam-Webster’s online dictionary, biodiversity is defined as, “the existence of many different kinds of plants and animals in an environment” (“Biodiversity”). The survival of various species on earth depends on biodiversity as each relies on another

Natural Resources Canada defines biodiversity as the “variety of life”, and expresses that endangered tree species are mainly threatened by forest clearance. In tandem with forest clearance, climate change also places stresses on endangered tree species, such as increased insect outbreaks and drought. Canadian forests compose 10% of the world’s total forests, and they consist of a wide range of plant and animal species, which places significance need for the impact of clearcutting in Acadian forests

the environment. The lack of preservation of the environment has led to ocean deoxygenation, pollution, and the loss of biodiversity. Ocean deoxygenation is causing many issues in marine life as well as death. The increase in pollution is placing many health risks to both land and marine life. The loss of biodiversity causes all living beings to be more vulnerable since biodiversity has many benefits. Firstly, the lack of preservation of the environment is causing the oxygen levels of oceans to decrease

populations and the global spread of pollutants leading to loss of biodiversity which is one of the most severe threats to sustainability. Land use changes have transformed land cover to farmlands, grazing lands, human settlements and urban centers at the expense of natural vegetation particularly in West Africa. These changes are associated with deforestation, biodiversity loss and land degradation. The relationships between land use and biodiversity are fundamental to understanding the links between people

In the article “What is biodiversity and why does it matter to us?” by Damian Carrington, Carrington dives into the pressing issue of biodiversity. He describes it as the most complex feature of our planet and the most vital. He goes into detail on how the losses of biodiversity are becoming as apparent, or even more so than climate change and how without it, there is no future for humanity. Carrington describes what biodiversity is composed of, he states that it starts with genes, species, communities

DISCUSS THE CHALLENGES ASSOCIATED WITH BIODIVERSITY LOSS FOR 21ST CENTURY CONSERVATION BIOLOGISTS AND SOCIETY AS A WHOLE Although sustainable development has been at the forefront of international agenda for many years, we continue to focus on the growth of the economy without worrying about the impact on the environment. Currently, our ecological footprint (the area in hectares that we require to provide us with the ecological goods and services we use) is far exceeding our biocapacity (the actual

Canberra- a city of biodiversity and sustainable living? Define biodiversity and sustainability and show how it is linked with Global Systems. What is the impact of unsustainable practices in the development of new cities like Canberra on Global Systems? (Draw on any experiences from your own background) What issues or problems are evident in current Canberra planning? Explain how science helps Canberra planners to maintain biodiversity and provide sustainable living. Choose ONE factor (relate

programmes in the preservation of biodiversity for future generations. Nowadays one of the most important issues is preservation of biodiversity. Although most of the damages to our environment were made in the past, since there were less education and consciousness between people, there are still many factors threatening the world heritage. So, it must be the duty, but at this stage even a challenge, of the community and of each individual, to preserve the world’s biodiversity without drastically reducing

As concerns on the status of global biodiversity heighten, the international zoo movement has gradually adopted conservation as its mantra. World-class zoos have invested substantially in species conservation and animal research as part of their involvement in wildlife conservation. However, zoo exhibit interpretation, policy development, and strategic planning are yet to be organized around a well-developed agenda with a clear set of conservation objectives (Conway, 1995). The zoo community seeks
