America wants to develop bullets that, when falling to the ground, will grow into trees

Those deadly bullets can also harm Earth's health.

America is facing the problem of guns, can be considered a kind of redundancy in some way: they must do to handle the pollution caused by the countless shells after each training session bullets on school sports here?

On the battlefield, the soldiers use bullets with great power and damage, but when the soldiers train, they use a bullet designed specifically for the field. These shells, according to the US Department of Defense, are "either left on the ground of the arena, or buried deep in a few meters of land".

The materials that make these bullets will gradually decompose but things don't stop there, they pollute the soil environment during the decomposition process."Those chemical components need several hundred years to be completely decayed," the Ministry of Defense said.

Chemical components in the shells need several hundred years to completely decay.

With the identification of the problem, they also mentioned ways to overcome the problem of pollution. The Ministry of Defense has proposed that the projectile bullets should be produced with easily decomposing materials and even, add plant seeds into bullet components so that when the shells hit the ground The tree may have a chance to grow.

According to calculations, tree seeds will not begin to grow until they are in the ground for several months. Moreover, animals can also eat these plants without harming their health.

This idea sounded completely reasonable and feasible, even the Ministry of Defense made investment calls to turn this idea into reality. Still, there are technical and biological obstacles to this problem.

In 2013, the inventor was also an artist, Per Cromwell developed a shotgun shell containing the peony and daisies - his desire to design this shell was " bring life to this world " , not to serve the purpose of killing a bullet.

The only problem in this dream artist's design is that he cannot find a suitable mixture of gunpowder and seeds, the seeds are always burnt out when the gunpowder is burned.

The US Department of Defense also has a desire to develop a synthetic material that mixes seeds.

And yet, the US Department of Defense's request is bigger than the bullets on the field. They also have the desire to develop a synthetic material that mixes seeds , a material they can commercialize it.

Such a dream material can be used in many other areas. In construction, materials from a removed house can be turned into a garden full of trees and flowers around the new house will be sprouting. The bottles and beakers after each music festival can be collected and turned a vacant land somewhere into a beautiful little forest.

The cleaning potential of such a material is limitless - but that's still the prospect of "once we have that material".
