Verse 1

```

Beautiful Earth, more beautiful with flowers and trees,

But now it's a mess, no cute little flowers.

Garbage dumps are everywhere, the beautiful green earth.

We need to act now, before it's too late.

```

Chorus

```

We're the stewards of this land, it's our duty to protect,

For our future and the sake of all the creatures.

Let's clean the air and water, let's plant more trees,

It's time to heal the world, it's time to believe.

```

Verse 2

```

Every little action counts, pick up the trash, reuse, and reduce,

Conserve energy, save water, let's make a change.

We only have one Earth, let's treat it right,

For generations to come, let's make it bright.

```

Bridge

```

There's a place in your heart, let love be the light,

It can heal the world, make everything right.

If we really try, we'll find a way,

To protect our planet, once and for all today.

```

Chorus

```

We're the stewards of this land, it's our duty to protect,

For our future and the sake of all the creatures.

Let's clean the air and water, let's plant more trees,

It's time to heal the world, it's time to believe.

```

Outro

```

Let's join hands and make a difference, one by one,

For a better world, let's start today.

We can do it together, it's not too late,

Let's heal the world, once and for all, it's our fate.
