Population and Climate ChangeA “Malthusian” theory about the relationship between population growth and the environment suggests that as populations grow, they will strip their resources leading to famine, hunger and environmental degradation.As detailed further in this site’s section on population, that is an oversimplification and has largely shown not to be true. Instead, it has been factors such as politics and economics (i.e. how we use our resources and for what purpose) that has determined environmental degradation or sustainability.For example, the world’s wealthiest 20% (i.e. the rich countries) consume approximately 80% of the world’s resources, while the rest of humanity shares the other 20% of resource consumed, as noted in the consumption section of this web site.In regards to climate change, countries with large populations such as China and India have not been the countries contributing greenhouse gases for the decades that has been required to trigger climate change, as noted further above.While in total amounts their emissions might be high (China is second largest emitter after the United States, for example), per person, their emissions are significantly smaller as noted earlier.

as countries such as China, India and Brazil grow in prosperity, there will be large populations with purchasing power, consuming more goods and services, thus making more demands on the planet.Indeed, many environmentalists have constantly noted that if such countries were to follow the style of development that the rich countries used and emulate them, then our planet may not be able to cope much longer.

researchers have found that depending on what variables you factor in, the planet can support an extremely large population, or an extremely small one. These ranges are ridiculously wide: from 2 billion to 147 billion people! Why such variance? It depends on how efficiently resources are used and for what purpose (i.e. economics).

Nuclear power remains dangerous, polluting, expensive and non-renewable. More nuclear power means more nuclear weapons proliferation, more nuclear-armed states, more potential "dirty bombs" and more targets for terrorists. It also means less resources invested in real solutions to growing energy demands.

If we would replace all fossil fuels with nuclear power, the world would run out of uranium in less than four years.

Currently, nuclear is a marginal energy source, supplying only two percent of the world energy demand, and there is no realistic scenario in which this could be significantly increased.

Over the past 150 years, deforestation has contributed an estimated 30 percent of the atmospheric build-up of CO2. It is also a significant driving force behind the loss of genes, species, and critical ecosystem services. However, in the international policy arena, biodiversity loss and climate change have often moved in wholly unconnected domains. — Climate, Biodiversity, and Forests, World Resources Institute, 1998

Carbon Sinks and LandA mechanism suggested for tackling climate change and warming has been the idea of using "Carbon Sinks" to soak up carbon dioxide. To aid in this, reforestation, or planting of new forests, have been suggested. This is a popular strategy for the logging industry and nations with large forests interests, such as Canada, the United States, various Latin American nations, and some Asian countries such as Indonesia.While there may be some potential in this solution, it cannot be effective on its own. This is because it legitimizes continued destruction of old-growth and pristine forests which are rich ecosystem and have an established biodiversity base (albeit shrinking now) that naturally maintain the environment (at no cost!). Creating new forest areas would require the creation of entire ecosystems. It is also criticized for being a quick fix that doesn't tackle the root causes effectively and doesn't lead to, or promote actual emissions reduction.

Environmentalists and others point out that the use of carbon sinks is a big loophole in the Kytoto Protocol; that if carbon sinks can be counted towards emissions reductions credit, then industrialized countries would be able to meet their commitments while reducing emissions by less than would otherwise be required. Because they are carbon sinks, it means that when forests burn or as vegetation naturally dies, they release more carbon too (because it is stored carbon). As the climate changes, it is possible that there may be more forest fires etc, releasing more carbon. (And then these sinks would become sources!)

New Zealand comprises two main islands (called the North and South Islands in English, Te-Ika-a-Maui and Te Wai Pounamu in Māori) and a number of smaller islands, located near the center of the water hemisphere. The total land area, 268,680 square kilometres (103,738 sq mi), is a little less than that of Italy and Japan, and a little more than the United Kingdom. The country extends more than 1600 kilometres (1000 miles) along its main, north-north-east axis, with approximately 15,134 km of coastline. The most significant of the smaller inhabited islands include Stewart Island/Rakiura; Waiheke Island, in Auckland's Hauraki Gulf; Great Barrier Island, east of the Hauraki Gulf; and the Chatham Islands, named Rēkohu by Moriori. The country has extensive marine resources, with the seventh-largest Exclusive Economic Zone in the world, covering over four million square kilometres (1.5 million sq mi), more than 15 times its land area.[5]

Although Māori culture was a totally stone-age culture until the arrival of Europeans and the introduction of metal, it was highly evolved. The various working materials used before the Māori had access to metal were mainly bird bones, whale bones, ivory teeth, both dog and human bones, and also stone, from the large stone resources which had been discovered further inland within New Zealand.

› Māori : The name "Māori" originally meant "the local people", or "the original people". Māori was a word which signified "local" or "original" - as opposed to the new arrivals - white European settlers - the "pakeha". With the arrival of European settlers, the word Māori gradually became an adjective for the "Māori people". This change took place before 1815.

It also urged governments to engage civil society and line ministries in mobilising resources for tuberculosis (TB).

Quite a large number of civil society organisations and NGOs have no organically-evolved mandate from the citizens,"

Mkaronda said complaints about NGO conduct may sometimes stem from public misunderstanding about the roles of these groups: "For example, the Zimbabwean community in South Africa expects us to mobilise resources to sort out shelter, feeding and legal (immigration) status. Yet our role is to highlight the crisis in Zimbabwe."

believes self-regulation may hold the key to improving matters: "It would be a good idea if NGOs and civil society groups came up with a code of conduct like the one which guides other professionals such as medical doctors and lawyers."

after 2000 as health delivery services declined amid growing international isolation.

he used to give her older children, who have since finished their primary education, supplements like peanut butter. But now she cannot do the same for her three-year-old son because of escalating prices.

Zimbabwe's economic decline has led to the breakdown of the country's health delivery system. Health care is now characterised by acute shortages of drugs and skilled personnel.

Industrialised nations are responsible for the bulk of greenhouse gas emissions - both today and historically. In the past, economic progress was linked directly to carbon dioxide emissions (via the burning of oil, coal and gas to generate energy). Renewable energy sources change this, but only a small number of nations have begun to implement them in earnest.

Two billion people – one third of the world's population – have no access to electricity for basic needs such as lighting or cooking. Getting people the clean and reliable energy necessary for essential needs such as clean water, health care facilities, heating and lighting is one of the most pressing problems facing humanity today.

Industrialised nations have the capital, resources and expertise to jump-start their renewable energy industries. Obviously, countries with advanced space programs, established higher educational systems and abundant cash for investment are better positioned to implement these new energy technologies then countries still struggling with basic energy needs.

This process has to begin with an attitude change in the people.

The international system cannot determine for the people the needs, however obvious the needs may be.

MDGs are derived from the international system rather than the domestic environment. They are thus perceived to be foreign, however good the intentions may be.
