Honestly your question sounds bias. Scientist in 1850s thought 2 billion was the capacity that the Earth could hold. they were right except for one big factor; technology.

The plow basically allowed us to make more effecient use of the land thereforth the capacity grows. Fusion reactors, Carbon nano tubes, artificial stem cells, and what not will soon come along. heck a 1hectreacre hydroponic farm that is 33 stories high could supply food for 60k people! now imagine the capacity for Earth! *also it is a closed system requiring no pesticides, 10 times less water, 10x more food, year round production blah blah blah. Time and neccesity bring out the best in humanity- be a bit pacient and assist in the cause if you can. 2050 will ecentually get here (est time for fusiob twch to take full effect).

Actually if we can't save and protect our environment then we have also no right to deteriorate our environment. So, if we are utilizing the resources of environment, it's our duty and responsibility to prevent our environment from the above mentioned problems and if we don't protect our environment in time,we could not imagine what our future will be.That's why not only one person, but everybody should be concern about the protection of environment.

The problems mentioned in your question is actually right. The environmental pollution and the environmental destruction is reach the maximum at present. So If we are not ready to save environment then the environment assassination will happen soon. If we try to care we can extent its life.So my opinion is still we wants to care about environment

:)

I am always trying to take care of our environment.

yes because if environment is there only then we can survive...

I do, but because I am a kid I don't matter.

With over 7 billion people here now, with industries being more destructive to our environment than in any moment in history, with our oceans being swept clean of all creatures either by toxic waste-related deaths or by over-fishing, with cities like Beijing experiencing unprecedented smog that it's forcing its citizens to wear respirators just to get to work, with business owners facing little to no accountability for their actions in precipitating such a state, do you really still care and think, in spite of all the gargantuan profits many industries earn (minus the petty fines they are imposed in contrast), we can still 'save' the environment?
