: i have seen lands that have been turned from jungle into desserts by people in a matter of a couple of years ,because of the slash and burn method used by settlers and expanding agriculture,and i have seen rivers dry up because of deforrestation in many places in Africa and Mexico ,
i live now by the side of a river in Mexico where,in 30 years 5 species of fish have become exstinct .
and part of the year the river is dry this is for longer every year because of over use of water by agriculture and as a result of deforrestation.
there are natural cycles in the planets life
but a lot is influenced by mans existance ,and this is increasing with overpopulation,putting strains on Natural resources and increasing contaminations as well as destructions of essential componants the ensure living conditions for all life forms
in North Africa,India,Mexico ,millions of people are effected by land loss and desertification
in recent times thousands of people have died because of exessive heat,usually old people.in India ,Mexico and France,
deforestation causing desertification,the desert conditions causing very cold nights and scorching hot days
in china, thousands of what used to be farmers are running for their lives from the dust storms that have burried their towns and turned their lands into dessert,the globe where they were got to hot for them .
and instead of producing food they are now needing it from some where else,and they will drastically effect the world food prices when they start buying water in the form of grains ,at any cost destabalising governments, in some countries ,could be the result
(are you seeing more Chinese around interested in agricultural lands ,we do here in Mexico)
,the Sahara is growing by 7 kilometers a year
and all of the desserts we know are a results of mans actions ,and they are increasing ,not getting less ,in the dinosaurs days ,there were no desserts.
collectively this planet is drying up because of bad farming practices like,over grazing and fertilizers,
as far as the food production is concerned, Global warming or some of its effects are serious,rising seas result in landloss
each degree rise in temperature means 10%crop loss
more landloss because of desertification every year,we have less areble land to produce food ,for an extra 70 million people ,
and there is less and less water (because of deforestation),to irrigate this production ,
and there are less and less farmers to do it..
who are overpumping deep carbon aquifiers
who are plowing more and more unstable lands because they have lost so many million hectares to desertification ,
because of bad farming practises ,such as using fertilizers and heavy machinary or over grazing
as to when it beoes critical depends on population growth

No I do not think we are mistreating the planet. The worlds population growth potential is only increasing and that means our natural resources will dwindle. Just from the basic needs of that population.
If you want a good comparative look at the the estimated population of China 70 years ago. Their population was just about 100 million more than is in the US right now. Then take a look at the land mass. China is just a little larger than the US. Now look at their population again.
Then think of what it would take to support a population that size, just in basic necessities. I can only imagine what the strain is on their agriculture and such. I see this in our future. I can see in our future a population so great that we would be importing more basic necessities than we can produce.
Even India is in no better shape.
As to the when in your question, if humans do not get any smarter, it will be sooner than we will think.

I don't believe we are mistreating it. Although I do think we can do better during our time here. This planet has gone thru worse hell than we ever have or ever will put it thru. It has taken hits from asteroids, survived an ice age, plus has gone thru other natural disasters that humans could never replicate. This planet will still be here even long after humans are extinct. There are people out there who may say we are killing our planet but don't believe that. We will never "kill" this place.

U might unlike my answer. no longer something, the few that are conscious to the subject of our earth do no longer even bypass away a dent in what maximum human beings will do. The few will sluggish it down, even in keeping with risk by using 1000 years. yet, purely like with maximum issues human beings will wait to the final 2nd. purely like maximum do for christmas procuring on the twenty fourth of Dec. however the twenty fourth would be too previous due with regard to earth. in the tip there'll could be harsh very virtually marshal regulations for pollutants. The question is will they be enacted too previous due?

Nature has built in automatic recycling of our air. This planet has many natural recycling. Plants have done a great job.
