S.O.S. p:ARK


#sosPark Weed is a misplaced plant in the eye of human, but nature never discriminate them. Whether they survive or not depends on their adaptability. Sometimes they are even useful and beneficial to the ecology. We human see them as enemy because they are out lof place and trying to see the situation to best benefit our kind. We gave them name like invasive species and separate other as native. And in any case, efforts to restore ecosystems to an imagined pristine state almost always fail: once a species begins to thrive in a new environment, there’s little we can do to stop it. Indeed, these efforts are often expensive and can increase rather than relieve environmental harm. An alternative is to embrace the impurity of our cosmopolitan natural world and, as some biologists are now arguing, to consider the many ways that non-native plants and animals — not just the natives — benefit their environments and our lives. I see this as a metaphor of immigration issue and how we should see it as positive and embrace instead of reject. Hope this plant based learning will enlighten our human condition.

I like to proposed a field that is left to grow wild and only be mow into a labyrinth pattern to enable visitor to walk into this path and meditate about position that we take and opinion that we had. Ultimately understanding that we are part of nature and migration is a natural process and will continue no matter what. We had to slowly break down political barrier, questioning a nation sovereignty, start formulate a better way we can live together in this world that is getting smaller and homogenized.

"If we confine the concept of weeds to
species adapted to human disturbance,
then man is by definition the first and
primary weed under whose influence
all the other weeds have evolved."

- Jack Harlan, Crops and Man


"Weed is simply a plant whose virtues
we haven’t yet discovered"

- Ralph Waldo Emerson
