i have to do an imformative speech on recyling and my main points are : what to recycle, where to recycle, and what products are recycled materials are made into.
all help is appreciated very much!!

The models are hind-cast to fit past climate data. Since this climate data has been altered the models are fundamentally flawed and therefore do not fit the REAL temperature curves going forward. It would make sense that the models don’t parallel observation.

Why not just throw our litter on the floor? It would eventually return to nature: decompose more quickly than Landfill. How is piling plastic bags full of rubbish, on top of thousands of other plastic bags full of rubbish in landfill sites better for the Environment?
(will take a few mins to download)
Explanations about how we process rubbish all the problems associated with it
and what may be done in future and all problems. There is no evidence to suggest
that landfill is not a problem. There is more evidence to suggest there are more
problems than we knew about.

Climate Change and Waste

Climate Change and Stopping OVER Consumption
•Waste prevention -the best environmental option, avoiding resource use
•Reuse -reduces need for resources and manufacturing
•Recycling -reduces need for extraction and processing of new resources
•Composting -returns nutrients and structure to soils; displaces other fertilizers; sequesters carbon; and, in the case of anaerobic digestion, produces methane which can be used as a 100% renewable energy source.
•Then we must phase out the rest -the residual waste, which is currently landfilled or incinerated
–Phasing out residual waste is the right long term direction, both for resource efficiency and climate change.

Biodegradeable Wastes Returning to the soil

Campaign Guide. This is old research but demonstrates current arguments. Simply states why landfill sites are not well managed.

Why putting waste on the ground is a great idea (like in French Vineyards) where it is not even sorted before placing on ground.

SO In the worst case scenario even if you do not compost just place the waste on the land, after all the organic material decomposes you are left with the plastics tins, glass, etc which does not biodegrade. This is already ‘presorted’ so it would just be a case of collecting up these materials for recycling.

Not looking like such as stupid idea is it now?

Green chemistry has 12 pricnciples (it can be searched on internet).
Apply one or more principles to your nearlest working to protect environment. For instance, desingation green plastic (PVC) product by using non toxic additives. But what additives are non-toxic and how is cost and product propeties if using those additives?

If we tallied up all the water we have stored, outside the water cycle, in the millions of places we hold it, dams, tanks, in toilets, car radiators, refrigerators, pipes, most of the products in our supermarkets, hot water systems, etc etc, the list would be huge. How much water in total would there be in these places? (how much water is in Coke cans at the moment?)

And, hypotheticaly, if all this water was returned to the water cycle, would it have any impact on the worlds current water crisis?

I’m doing a science project about water pollution and i have to discuss any actions or conservation efforts because of water pollution. And i really dont understand this question. So somebody that understands it , can they please help me? Mmm, thanks, oh please ANSWER this A.S.A.P because this project is due TOMORROW!

What forms of water recyling are there and is desaliantion safe? what are the advantages of desalination and what could be done before we have to turn to desaliantion?

thanks, if you could answer any of these questions =]

The world’s oceans are becoming more acidic which in turn are damaging shell making organisms including coral reefs.

The question says it all. Do you think there would be change anywhere (environment, ecosystem, food chain etc.)?
This question was on my mind since I first heard of global warming and climate change. It seems to me that humans do nothing but ruin the environment. I would like to see if anyone agrees or disagrees with me. Please think carefully before answering. Everyone is welcome to express their opinions.
Thank You.
