- Rewilding shouldn't be an excuse to remove people from the land
1 wondering:
- I wonder why it is so hard for humans to just "step back" from an ecosystem and just leave it to thrive on its own. Why do humans always need to intervene?

Rewilding

Ghost ecosystem

We can still restore many of the ecosystems the world has lost.

2 learnings

The surviving animals live in ghost ecosystems adapted to threats from species that no longer exist.

Some of these animals can reshape their surroundings, creating conditions that allow other species to thrive.

1 wondering

I wonder if animals appreciate what humans are trying to do for them, or if they find it rather annoying and unnecessary?

To protect our children's future.

Positive Feedback

Negative feedback

2 learnings

And the natural world is full of these mechanisms (feedback loops) formed by the links between living and nonliving things that build resilience by governing the way populations and food webs respond to events.

Note that each feedback is the product of the links in the loop. Add one negative link and it will reverse the feedback force entirely, and one weak link will reduce the effect of the entire feedback considerably. Note that each feedback is the product of the links in the loop. Add one negative link and it will reverse the feedback force entirely,

2 learnings that I acquired

- We can restore existing species to where they used to live. Some animals can reshape their surroundings to a condition that allows other species to thrive.
- A trophic cascade is when change that occurs at the top of the food chain has an effect on the succeeding levels.

Amanda Villegas

3 words:
extinction
restoring species
trophic cascade

2 learnings:
I learned that we can use unused lands such as abandoned farms (as stated in the video) to grow more trees and plants, provide more habitat locations for animals such as wolfs and mosses, and create conditions for other species to thrive. With this, species were able to work out their food chains and find a substitute for their prey such as wolves devouring coyotes leading to increases in rabbits and mice and this gives a more variety of food for hawks and weasels. Thus, the regrowing of reforestation has led to more habitats, more species to thrive, and more food and varieties for species to eat.

I also learned how if one level of the food chain falls, this also affects the rest of the levels (trophic cascade). Through rewilding, we will be able to undo the damages we caused to the ecosystem and reestablish species that were affected and driven out. In simple terms, rewilding is where we bring back the species that bring back dynamic processes and go back to the food chain.

1 wondering:
I wonder if we could really bring back the extinct animals or the big animals we used to have.

Countdown (less time left)

2 learnings
I learned how we have less time left to do something to save the earth. The video states a lot of tipping points some countries have faced such as in Siberia, permafrost is thawing at dramatic scales, Greenland losing trillions of tons of ice, the Amazon rainforest is weakening and might start emitting carbon within 15 years, and West Antarctica may have overlapped with its tipping point. There are three threats to tipping points: sea level rise, stabilizing temperatures becoming harder, and if one crosses its tipping point, this causes others to stumble as well.

I also learned how it is all up to our decisions and actions to know if our world will fall apart after 10 years. Children are mostly aware of what is happening around us and are in "disbelief" about why our earth is in a bad state (not really bad). As we pass on the wheel to other generations, we first have to make sure the environment we are living in at the moment is safe.

1 wondering
I wonder if we will be able to achieve all the goals we have in store for our environment before 10 years.

2 learnings that I acquired

- We are close to turning the earth into an unsafe operating space for humanity, as climate has reached a global crisis point.

- Tipping points bring three threats: (1) sea level rise, (2) excess carbon emission leading to potentially unstable temperatures, and (3) these systems have a domino effect wherein crossing one tipping point would lurch you closer to others.

1 wondering I have in mind

- In what ways can people take action to address this global crisis to reach a significant improvement?
