More foliage and environmental details

One of the most important parts of the wild update is adding more life to the overworld. From some of the concept art shown in Minecraft Live, it is already clear that the birch forests will be updated, but I think one of the best things the developers can do is to add more life to the world. This feature should be different from how other features and updates are approached, Instead of adding one big feature, lots of little details that behave similarly and simply should be done to every biome. For instance, make lots of different types of foliage, then make different variants of that foliage, then scatter it throughout the whole world. Don't take forever to make everything perfect, get a few perfect things and make similar stuff. That means falling leaf particles, more mushrooms of different sizes, ambient bugs and sounds, everything you can cramp in to make the forests feel alive.
