WHY
So why is that
Illustration
So many people want to care for the Earth.
So why is that
first step so hard?
There are three big reasons. The Earth Project is built to help you over each of those three walls.
01
It doesn't feel like my problem
ChuraThe Earth's problems feel like something far away…
DonguThat's why I share the real voices of people acting for the Earth. Meet them, and it suddenly feels close.
02
Not sure how to take the first step
ChuraI want to do something! But what, where, and with whom?
WatariLook it up, ask questions, and find events and volunteering near you right away!
03
Hard to keep going, all alone
ChuraWhen I'm on my own, I just can't keep it up…
Dr. HouYou collect "seeds" while you play, and learning turns into titles. You can see your progress, and you have friends. That's how you keep going.
ONE STEP
Ten thousand people taking one step
Ten thousand people taking one step
beats one person taking a hundred.
About 10 tons
Litter our "Haisai Clean Team" picks up in a year
vs
About 11 million tons
Plastic waste flowing into the ocean each year
Source: Pew Charitable Trusts, "Breaking the Plastic Wave" (2020), estimate for 2016. The amount collected is our group's own yearly estimate.
Grandpa KamiThe Earth's problems are huge. One group alone can never keep up.
ChuraSo what if everyone takes just one step?
Grandpa KamiThen we can reach it. That's why the Earth Project puts "more people taking action" right at its heart.
