Trident

Trident is a submarine-launched ballistic missile with multiple indepdently targetable reentry vehicles. This essentially means that it is a nuclear cluster bomb, with each of the individual bombs having the ability to be guided to a chosen target. Each submarine can carry up to 16 missiles. A single missile carries up to 12 nuclear warheads, meaning up to 192 warheads can be carried per submarine. Each of these war heads is 8 times more power than the nuclear bomb dropped on Hiroshima.

Cobalt Bomb

A cobalt bomb is a nuclear bomb with a quantity of Cobalt-59 inside it. When the bomb explodes the Cobalt-59 is transmuted into Cobalt-60 and subsequently vaporised, falling back to Earth with the debris from the explosion contamination the ground. After 1-6 months the fission products from a normal thermonuclear weapon decay to a level tolerable by humans, however Cobalt-60 has a 5.27 years which leaves the fallout area uninhabitable for decades. After 53 years, a human would be able to spend 1-4 days exposed to the fallout with no immediate effects and the radioactive dose only becomes negligible after about 142 years.

Anti-matter Bomb

Just 1 kg of matter and 1 kg of anti-matter, if allowed to coalesce, would create an explosion equivalent to 3000 times the amount of power of the nuclear bomb dropped on Hiroshima. Scientists have recently increased the time they are able to keep anti-matter separate from matter to 16 minutes.

Scientists hold anti-matter for 16 minutes

Food

Foley argued that the world should focus on five big things:
1) Stop razing forests and savannahs for farmland — by, for instance, shifting away from crop-based biofuels.
2) Focus on boosting yields where it’s technologically doable, especially in Africa.
3) Figure out how to use water and fertilizer more efficiently everywhere.
4) Pare back the amount of meat in our diets.
5) Cut down on the enormous amount of food waste worldwide.
