I don't understand the biodegradable part being an issue. Coffins are buried 6 feet underground and if it wasn't for the above ground markers, there would be no evidence of their existence.
Grass, plants and trees still grow and animals and insects still do their thing in grave yards regardless of buried boxes. Pretty much the same as when the ground is full of large bolders that have been there for millions of years.
There's a very large cemetery in my town and if it wasn't maintained by grounds keepers, it would fairly quickly get taken over and swallowed up by nature.
Until recently, burials could happen all "higgledy-piggledy" depending on random and contradictory laws, or no laws at all (in many jurisdictions, a family could simply bury a member on family land). In the last 40 or 50 years, most states have laws requiring burials to include burial vaults (basically, huge Tupperware containers which prevent leakage into local water supplies). The vaults are also sturdy enough to prevent collapse. So, "green burials" are required to be located away from aquifers.
So now, traditional burials are fairly sterile. Yes, such burials leave nothing to attract animals and insects. Cremations are about 25 percent of all end-of-life solutions, and avoid animals and insects, too. Green burials are gaining in popularity. Ossuaries seem pretty "green," too, as they invite insects to aide in the decomposition process for the first year after death. In my own state, laws allow for a unique kind of "green burial" which is favored by western cowboy enthusiasts (shroud or pine box, nothing fancy; dig a ditch in allowed locations, play some guitar-and-banjo music, and wave goodbye.
