Environmental Issues


Biodiversity


The variety of life on Earth, its biological diversity, is commonly referred to as biodiversity. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach. In some way or form, almost all cultures have recognized the importance of nature and its biological diversity for their societies and have therefore understood the need to maintain it. Yet, power, greed and politics have affected the precarious balance. 


Loss of  Biodiversity and Extinctions
It has long been feared that human activity is causing massive extinctions. Despite increased efforts at conservation, it has not been enough and biodiversity losses continue. The costs associated with deteriorating or vanishing ecosystems will be high. However, sustainable development and consumption would help avert ecological problems. 




Nature and Animal Conservation

Preserving species and their habitats is important for ecosystems to self-sustain themselves.
Yet, the pressures to destroy habitat for logging, illegal hunting, and other challenges are making conservation a struggle.

Climate Change Affects Biodiversity
Rapid global warming can affect an ecosystems chances to adapt naturally.
The Arctic is very sensitive to climate change and already seeing lots of changes. Ocean biodiversity is already being affected as are other parts of the ecosystem.

Addressing  Biodiversity Loss
At the 1992 UN Conference on Environment and Development (the Earth Summit), the Convention on Biological Diversity (CBD) was born. 192 countries, plus the EU, are now Parties to that convention. In April 2002, the Parties to the Convention committed to significantly reduce the loss of biodiversity loss by 2010.
Perhaps predictably, that did not happen. Despite numerous successful conservations measures supporting biodiversity, the 2010 biodiversity target has not been met at the global level. This page provides an overview on how the attempts to prevent biodiversity loss is progressing.

Climate Change and Global Warming
The climate is changing. The earth is warming up, and there is now overwhelming scientific consensus that it is happening, and human-induced. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing. Many are agreed that climate change may be one of the greatest threats facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities in weather patterns.
This section explores some of the effects of climate change. It also attempts to provide insights into what governments, companies, international institutions, and other organizations are attempting to do about this issue, as well as the challenges they face. Some of the major conferences in recent years are also discussed.
