Pollution isn't good.

Soon it will be the end

and we won't have a chance
 to do it all over again.
Earth is our home.
Let's take care of our world.
A time when Earth wasn't polluted
seems like a blur.
When will we ever learn?
I see fields of flowers
but soon they will be dying.
I don't know about you
but I am trying
to save our home.
So I'm writing this poem.
The world was once blue
but now it is grey.
Soon all happiness will fade.
Let's treat our home with love
so that He will start smiling
on his home from up above.
It was once  happiness,
it was once bright,
but now there is no more light.
The world is dark as night.
Let's try to make it white,alive
Let's fight.

DEFORESTATION

In the happiness we are in
I see trees of green.
Until when?
Many animals in the sky
Many animals on the ground 
Will it be like this forever?
Trees are disappearing
Gases I am breathing
What is happening?
What are the men doing?
Someone tells me: Deforestation!
And I answer,
"Sorry I don't know what that is."
Don't give up! Keep on trying to do your best.
Do your part,this is not my world,hope it is not yours either.
Without care
Without Earth
Without us.

Thanks Mum!

Happy Mother's Day

M - O - T - H - E - R

"M" is for the million things she gave me,
"O" means only that she's growing old,
"T" is for the tears she shed to save me,
"H" is for her heart of purest gold;
"E" is for her eyes, with love-light shining,
"R" means right, and right she'll always be,
Put them all together, they spell
"MOTHER,"
A word that means the world to me.
Howard Johnson (c. 1915)

 

                                                 

Compete or die!

Different species compete to survive and breed. The size of a predator population depends on the size of the prey population, and the reverse is true as well.

Competition
Habitats have limited amounts of the resources needed by living organisms. Organisms must compete with others in order to get enough of these resources to survive. If they are unsuccessful and cannot move to another habitat, they will die.

Animals
Some of the resources that animals compete for:
food
water
space

Animals may also compete for mates so that they can reproduce.

Plants
Remember that plants make their own food using photosynthesis, so they do not compete for food. Here are some of the things that plants do compete for:
light
water
space
mineral salts

Human beings
Human beings are very successful organisms. We compete with animals for food resources, and we compete with both animals and plants for space and water.


Predators and prey
Predators are animals that eat other animals. Prey are the animals that get eaten. The size of the predator population and prey population depend on each other.

If the prey population grows, predator numbers will respond to the increased food supply by increasing as well. But the growing predator population will eventually reduce the food supply to the point where it can no longer be sustained.
