It can spread over acres and acres of area,

Each of these forests is just two years old.

I have a forest in the backyard of my own house.

who facilitates the making of these forests professionally.

A forest is not an isolated piece of land where animals live together.

A forest can be an integral part of our urban existence.

is a place so dense with trees that you just can't walk into it.

It doesn't matter how big or small they are.

Most of the world we live in today was forest.

Then we built up our cities on those forests,

forgetting that we belong to nature as well,

as much as 8.4 million other species on the planet.

Our habitat stopped being our natural habitat.

A few others and I today make these forests professionally --

I learned how to convert natural resources into products.

we would drip the sap out of a rubber tree,

and make a tire out of it -- the product.

But these products can never become a natural resource again.

and convert them into an irreversible state.

Nature, on the other hand, works in a totally opposite way.

The natural system produces by bringing elements together,

All the natural products become a natural resource again.

when I made a forest in the backyard of my own house.

And this was the first time I worked with nature,

we have made 75 such forests in 25 cities across the world.

we find that every single element needed to make a forest

All we have to do is to bring these elements together

If the soil is made up of small particles it becomes compact --

We mix some local biomass available around,

If the soil doesn't have the capacity to hold water,

some water-absorbent material like peat or bagasse,

so soil can hold this water and it stays moist.

To grow, plants need water, sunlight and nutrition.

What if the soil doesn't have any nutrition in it?

We don't just add nutrition directly to the soil.

We instead add microorganisms to the soil.

They produce the nutrients in the soil naturally.

They feed on the biomass we have mixed in the soil,

so all they have to do is eat and multiply.

We survey the native tree species of the place.

Well, whatever existed before human intervention is native.

to find the last remains of a natural forest.

to see the seeds or wood of trees existing there a long time ago.

We research old paintings, poems and literature from the place,
