what are environmental issues with injection moulding?
just wondering about the environmental issues with injection moulding, doing a project in college, if you could help thanks a lot.
The Expert answers:
You know those gallon jugs that milk comes in at the supermarket? Those are injection molded.
IM is super-popular with plastics. So, basically every environmental issue with plastics, especially bottles, is applicable to injection molding.
Hell, some clever folks figured out how to injection mold glass a couple decades back, and now beer bottles are mega-cheap. The cost incentive to reuse them totally went away, so now they’re basically disposable; time was you paid a deposit on a beer bottle, and the company bought it back, steamed it sterile, and put more beer in it.

Do men and women view environmental issues differently?
Do men and women act in different ways in the natural environment? Do men and women view environmental issues differently?
Why do you think this is?
Are there any Ecofeminists in the Environment Section?
This is not homework Lol, it is years since I left school, I am interested in your views.
Brief Definition
Ecofeminism is the social movement that regards the oppression of women and nature as interconnected. It is one of the few movements and analyses that actually connects two movements. More recently, ecofeminist theorists have extended their analyses to consider the interconnections between sexism, the domination of nature (including animals), and also racism and social inequalities. Consequently it is now better understood as a movement working against the interconnected oppressions of gender, race, class and nature.

The Expert answers:
I don’t think the difference is any more distinct then the way that men and women think differently in general because of the way our brains are desinged…
THAT is a great topic to do research on…
The gender differences in how the brain works.

Nancy asks…
Conclusion of a project on environmental issues of Brazil?
I made a powerpoint presentation on the environmental issues of Brazil ( deforestation in the Amazon Rainforest). I am not able to make a conclusion ( only 1 slide for conclusion). Can someone please help.
I included
causes
consequences
government steps
what government should do to resolve the issue
and then i need a conclusion
The Expert answers:
A nice, strong conclusion is a great way to end a presentation — it leaves a strong imprint in the minds of your audience. I would talk about the importance of preserving forests (particularly in the Amazon), and make some predictions about the future; what the future might be like if the Amazon ceased to exist.
You could probably use 1-3 lines to write a brief sentence to summarize the Amazon’s importance, and another line or two to state your belief on what should be done about it (depending on your font size).
Hope this helped!
David asks…
what are some social, economical, and environmental issues of global warming?
basically i have to write something for science the question is ‘Is human activity responsible for global warming’ i need to write about socia, economical and environmental issues. help anyone?
The Expert answers:
Economic: Our generation gets the benefit of cheap energy from burning a huge fraction of the world’s fossil fuel capital. The next 50 generations pay the costs of lower crop yields, increased disease, flooding of coastal cities, more extreme weather, etc. Due to the climate change caused by burning that fossil fuel. Not because our generation consciously and explicitly decided to take for ourselves and let future generations fend for themselves, but for still less respectable reasons, not the least of which being because an entire political party within the country of the world’s greatest economy has made a conscious and colossally amoral decision to incessantly and blatantly lie about basic science.
U.S. National Academy of Sciences, 2010:

“Climate change is occurring, is caused largely by human activities, and poses significant risks for a broad range of human and natural systems.”
http://nationalacademies.org/morenews/20100716.html
“Choices made now about carbon dioxide emissions reductions will affect climate change impacts experienced not just over the next few decades but also in coming centuries and millennia…Because CO2 in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe.”
