2. Mini planes carrying out pollination
Most of our daily foods need to be pollinated to produce fruits, and up to 75% of all agricultural crops in the world needs the help of animals such as bees, butterflies ... to be able to poll. Researchers in Japan are experimenting with mini-planes that transport pollen from trees to trees on a giant flower to replace insects.

3. Self-destructing biological bullets
.
The "miracle" biological bullet that the US military is aiming for.
.
The United States Department of Defense is working on a new bullet that can reduce environmental pollution and self-destruct. This type of bullet is also being hoped to be able to creat foods for animals after use.

4. "Plastic" made from plants not polluting the environment
.
Drinkable plastic - a solution for the future?
.
A Indonesian bussinessman, Mr. Kevin Kumala, has succeeded in producing raincoats, handbags and food packaging made from cassava, a cheap and popular vegetable in Indonesia. It can self-destruct after being used.
