It is an honor for me to join this distinguished group of leaders from nations around the world. We come here in Copenhagen because climate change poses a grave and growing danger to our people.

American's belief of global warming sinking - below 50% for the first time in... - 1 views
-
I am learning more about global warming right now, and in particular what I'm wonder about is what caused global warming? I was researching this question online, and this blog post caught my attention because it is about global warming and I know that emissions no longer cause global warming by reading this blog post. "According to the survey, roughly a third of the people who believe in global warming think it is due to natural causes, rather than manmade causes such as industrial emissions. As a result, the number who say that global warming is caused by humans has dropped from 54 percent last summer to 45 percent now." The quote I chose here is basically saying that global warming is causing by natural causes but I don't think so. I think people cause global warming too. They kill trees and pour waste water into ocean and rivers. I think this is impressed because it makes me wonder will the percentage of global warming and pollution be higher next year?

RealClearPolitics - Obama's Remarks at the United Nations Climate Change Conference - 0 views

I'm learning more about Copenhagen conferences right now, and in particular what I'm wondering about is :''Why is the Copenhagen conferences so important? i was researching this question online,and this blog post caught my attention because the title of the blog is Obama's remake at the unit nation climate change conference,and i saw why this conference is important, because the people that join the conference is all the leadership of their country around the word. "Climate change will pose unacceptable risks to our security, our economies, and our planet. Climate change poses a grave and growing danger to our people" The quote i chose here is basically saying that the climate change is danger to the people. The climate change also will damage our security,our economies,and our planet. I think this is best because the conference it makes me wonder that the leadership of the world know the problem of this,so they just have a conference about the climate change,so they try to solve the climate problem,because it can be damage the world, so they try to decrease the pollution of the world ,some of their country cut the greenhouse gas emission, some of them cut the emission intensity. they do so hard to cut this,so i think it should have more conference like this, then they can make the world more better.

Recycling - Wikipedia, the free encyclopedia - 0 views

Recyclable materials include many kinds of glass, paper, metal, plastic, textiles, and electronics. Although similar in effect, the composting or other reuse of biodegradable waste – such as food or garden waste – is not typically considered recycling.[2] Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials bound for manufacturing.
-
In a strict sense, recycling of a material would produce a fresh supply of the same material, for example used office paper to more office paper, or used foamed polystyrene to more polystyrene. However, this is often difficult or too expensive (compared with producing the same product from raw materials or other sources), so "recycling" of many products or materials involves their reuse in producing different materials (e.g., cardboard) instea

Another form of recycling is the salvage of certain materials from complex products, either due to their intrinsic value (e.g., lead from car batteries, or gold from computer components), or due to their

Critics dispute the net economic and environmental benefits of recycling over its costs, and suggest that proponents of recycling often make matters worse and suffer from confirmation bias.
-
Specifically, critics argue that the costs and energy used in collection and transportation detract from (and outweigh) the costs and energy saved in the production process; also that the jobs produced by the recycling industry can be a poor trade for the jobs lost in logging, mining, and other industries associated with virgin production; and that materials such as paper pulp can only be recycled a few times before material degradation prevents further recycling. Proponents of recycling dispute each of these claims, and the validity of arguments from both sides has led to enduring controversy. Contents [hide]

Recycling has been a common practice for most of human history, with recorded advocates as far back as Plato in 400 BC. During periods when resources were scarce, archaeological studies of ancient waste dumps show less household waste (such as ash, broken tools and pottery)—implying more waste was being recycled in the absence of new material.[3]

In pre-industrial times, there is evidence of scrap bronze and other metals being collected in Europe and melted down for perpetual reuse.[4] In Britain dust and ash from wood and coal fires was collected by 'dustmen' and downcycled as a base material used in brick making. The main driver for these types of recycling was the economic advantage of obtaining recycled feedstock instead of acquiring virgin material, as well as a lack of public waste removal in ever more densely populated areas.[3] In 1813, Benjamin Law developed the process of turning rags into 'shoddy' and 'mungo' wool in Batley, Yorkshire. This material combined recycled fibres with virgin wool. The West Yorkshire shoddy industry in towns such as Batley and Dewsbury, lasted from the early 19c to at least the First World War

For a recycling program to work, having a large, stable supply of recyclable material is crucial. Three legislative options have been used to create such a supply: mandatory recycling collection, container deposit legislation, and refuse bans

Governments have used their own purchasing power to increase recycling demand through what are called "procurement policies".
