Suggestions
I feel that one suggestion would be to limit the number of animals at each box at a time, and the time they spend at each box. This is to prevent people from camping at boxes where they are safe. Carnivores and Omnivores should also not wait next to boxes, or the game would no longer be fair or fun.
The human, natural disaster and disease are also too OP, and should be nerfed. The animals should have some kind of defense mech against them, especially the human. I feel that it is quite unreasonable to have the human do anything he wants. Natural disaster and disease should also have limited space, as they have a ranged attack. They should also be able do bad stuff to humans, and not vice versa. (real life).

We should have several "stages". When one stage ends, the teacher would have to look at everybody's cards and those without either food, shelter and water will be eliminated. Humans should also be able to move the markers around the boxes so its harder for the herbivore.

Instead of having quite unrealistic Natural Disasters and Diseases, there can be 2 Virae and 2 Bacterium which gain members a minute based on how many people they have "infected". If a bacteria/virus has not newly infected anybody within 1 minute, it will 'die out'. Of course, the virae and bacterium have to tag others as well, and have to wait thirty seconds after one tag. (Limits number of newly infected people per minute to two or one.) See how long the virae and bacterium can run rampant!
The teacher can start "Natural Disasters" after 5 minutes, upon which the students in a one metre radius to the chosen "epicenter" will lose two lives, while all the others will only lose one life.
