CLIMATE CHANGE



A long-term change in the earth's climate, especially a change due to an increase in the average atmospheric temperature: Melting glaciers imply that life in the Arctic is affected by climate change 
Climate change is impacting human lives and health in a variety of ways. It threatens the essential ingredients of good health - clean air, safe drinking water, nutritious food supply, and safe shelter - and has the potential to undermine decades of progress in global health.
According to the World Health Organisation between 2030 and 2050, climate change is expected to cause approximately 250 000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress alone. The direct damage costs to health is estimated to be between USD 2-4 billion per year by 2030.
Areas with weak health infrastructure – mostly in developing countries – will be the least able to cope without assistance to prepare and respond. WHO supports countries in building climate-resilient health systems and tracking national progress in protecting health from climate change.
Reducing emissions of greenhouse gases through better transport, food and energy-use choices results in improved health, particularly through reduced air pollution. The Paris Agreement on climate change is therefore potentially the strongest health agreement of this century. WHO supports countries in assessing the health gains that would result from the implementation of the existing Nationally Determined Contributions to the Paris Agreement, and the potential for larger gains from more ambitious climate action.

Climate change : Alaskan wilderness oil exploration

Climate change: Alaskan wilderness opens up for oil exploration The giant Alaskan wilderness is home to many important species, including polar bears, caribou and wolves. Decades of disputeol on the rights to drill for oil on about 5%. Covering some 19 million acres (78,000 sq km) the Arctic National Wildlife Refuge is often described as America's last great wilderness. It is a critically important location for many species, including polar bears. In the winter months, pregnant bears build dens in which to give birth, as temperatures have risen and sea ice has become thinner, these bears have started building their dens on land.The coastal plain of the ANWR now has the highest concentration of these dens in the state the refuge is also home to Porcupine caribou, one of the largest herds in the world, numbering around 200,000 animals. In the spring, the herd moves to the coastal plain region of the ANWR as it is their preferred calving ground. This same coastal plain is now the subj...

ENVIRONMENTAL AWARENESS

What is Environmental Awareness? To define environmental awareness we must first understand the environmentalist movement. Environmentalism is an ideology that evokes the necessity and responsibility of humans to respect, protect, and preserve the natural world from its anthropogenic (caused by humans) afflictions. Environmental awareness is an integral part of the movement’s success. By teaching our friends and family that the physical environment is fragile and indispensable, we can begin fixing the problems that threaten it. How to Promote Environmental Awareness Before you can begin promoting environmental awareness in your community, you must first make sure that you have a thorough understanding of environmental issues. Stay up to date on environmental news, read books and other resources, and learn about the issues affecting your own community. It’s much easier to talk to others about the environment if you’ve already taken the time to educate yourself. Numerous resources are av...

ENVIRONMENTAL DEGRADATION

Environmental degradation is a process through which the natural environment is compromised in some way, reducing biological diversity and the general health of the environment. This process can be entirely natural in origin, or it can be accelerated or caused by human activities. Many international organizations recognize environmental degradation as one of the major threats facing the planet, since humans have only been given one Earth to work with, and if the environment becomes irreparably compromised, it could mean the end of human existence. One of the major threat the planet faces today, environmental degradation, is bound to make life difficult for all the life forms, including human beings, now or later. Studies by some of the eminent organizations reveal that the deterioration of environment is occurring at an alarming rate. In fact, the High Level Threat Panel of the United Nations has enlisted environmental degradation as one of the ten threats for us. This issue shares ...
