Protecting bits of nature here and there will not prevent humanity from losing our life support system. Even if areas dedicated to conserving plants, animals, and other species that provide Earth’s life support system increased tenfold, it would not be enough without dealing with the big issues of the 21st century: population, overconsumption and inefficient resource use.
Without dealing with those big issues, humanity will need 27 planet Earths by 2050, a new study estimates.
The world population, currently at seven billion, is well beyond Earth’s ability to sustain. By 2050, with a projected population of 10 billion people and without a change in consumption patterns, the cumulative use of natural resources will amount to the productivity of up to 27 planet Earths, the study found.
Sustaining the current seven billion people on the planet requires a major shift in resource use. At present, the average 
U.S. citizen’s ecological footprint is about 10 hectares, while a Haitian’s is less than one. The planet could sustain us if everyone’s footprint averaged two ha, Mora said.

Another of the authors, Peter Sale from the Canadian Institute for Water, Health and the Environment, put it like this:
"We are just taking too much - managing forests in such as way as they degrade, same with coastal waters, and we have to stop doing this as a species.
"I don't have a solution - I have struggled for some time trying to think what is the way to get people to realise how important this is - but if we don't find it soon, the future is a very grim one.
"We're talking about losing 50% of species in the next half century - that's faster than any previous mass extinction event - and anybody who thinks we can go through a mass extinction and be perfectly fine is just deluding themselves."
THE SOLUTION To Over Consumption (some notes)
Assuming that a World anti capitalist revolution is not going to happen right now… more’s the pity… It’s high time that radical environmental groups began to think REAL.
One step that could be taken is to stop using fossil fuels. A huge but not impossible task. Renewable energy is approaching the level where it’s ‘cheaper’ than using fossil fuels. A safer, CO2-free non polluting fuel for vehicles has always existed SEE HERE https://thefreeonline.wordpress.com/category/ammonia-nh3-co2-free-fuel/
But the root of the problem is the mad greed and superconsumption that is the basis of the universal capitalist system.
A common sense moral approach would be for example to sabotage a coal plant, an arms or car factory etc. This is already happening, on a very small scale. Check it out HERE, https://thefreeonline.wordpress.com/category/prison Such largely symbolic publicity actions maybe only benefits the competition and put people out of work, but if many thousands of people were to start doing it …
Blogging to the consciences of middle class youth is all fine and good, but Direct Action on a massive scale is now needed.
Another sane and moderate idea (since their actions are destroying the planet) would be to physically attack investors and directors in the worst Corporations. Let them retreat already to the luxury bunkers they are urgently preparing. However the ‘ruling class’ have all the security forces on the planet just itching to pounce on anyone who ‘gets real’ in this way, and every media outlet ready to scream ‘terrorist’ for the next 20 years. Also the question of guilt is very relative, few really understand what they are doing, and all of us know we are participating in trashing the Earth…. cont/
