Biological diversity is what kept us from becoming extinct... so far.
To show there is no one right way of living...
A broadening of one's world view, opening to different perspectives, learning about different cultures and customs, and best of all, the food.
The alternative is a world where everyone looks the same, eats the same food, works for the same company, thinks the same and believes in the same thing. That's why diversity is not just good, but a blessing.
diversity enables creatures to compete successfully for survival... It's nature's way of giving life the best chance for success so yes - it's a 'good thing'.
Because if we all look the same, there is no desire to discover what is different.
because white people suck.
DNA coding for various animals calls for slight or high variations of diversity.
