One of Minecraft's weaknesses is its static flora. Plants do not grow on their own unless planted, and their main purpose is to provide the player with resources. Luckily, there is Bacteria Mod.

This is a real find for biology lovers. The modification adds many different plants and bacteria to the game world. The latter not only grow actively, but also fight for existence with other vegetation.

Some life forms are completely dangerous - they destroy everything they can reach. Therefore, experiments with them should be carried out in a sealed bunker. Otherwise, the infection will break out, and the consequences will be catastrophic.
