When the environment is fragmented‚ the large patches of habitat no longer exist. It becomes more difficult for the wildlife to get the resources they to survive‚ possibly becoming threatened or endangered. The environment suffers without the animals that play their role in the food web. Aggressive Plant Life A more critical result of habitat fragmentation is land
