Danaus plexippus was very common species two decades ago in Canada , specially in southern Ontario . You could find its larvae on almost every milkweed bush and in October many of them were geting ready for their long trip to Mexico gathered near Lake Ontario.
Indeed in the recent years the number of butterflies drastically decline . The blaim for that went to deforestation in Mexico where the butterflies are overwintering . In Canada it is protected species now. It is still rather common species but if some action will not take place perhaps it will extinct same way as many species in Western Europe .

Deforestation in Mexico, RoundUp-compatible-GMO in North America, this is how 3 countries are killing one of the most beautiful natural scene on Earth... that is the Monarch migration.

It is very sad . Without using all the chemicals, antibiotics , genetic modificated plants and animals we can not produce enough food for seven billions of people .
To survive in such a number we kill everything around us .
Depressing, but real ...

Not totally real though...
10 billion of humans can survive with a less industrial agriculture.
It is all about profit, not about human survivance.
Exemples : some GMOs and neonicotid pesticids are now forbidden in Europe. Is Europe impssible to feed the whole world today. I doubt so.
Note that I am not against all GMOs. I hate those who are used to pollute more like the RoundUp-compatible-GMOs

Humans are a plague on the Earth that need to be controlled by limiting population growth, according to Sir David Attenborough.
The television presenter said that humans are threatening their own existence and that of other species by using up the world’s resources.
He said the only way to save the planet from famine and species extinction is to limit human population growth.
“We are a plague on the Earth. It’s coming home to roost over the next 50 years or so. It’s not just climate change; it’s sheer space, places to grow food for this enormous horde. Either we limit our population growth or the natural world will do it for us, and the natural world is doing it for us right now,” he told the Radio Times.
I have always admire he's passion for nature in he's TV shows .

And he is totally true ! Climate change is an issue, sure, but part of the species can resist it. Lack of natural space will destroy nearly all life on Earth... including us  |
