Need statement:

If there are too many birds and animals in your yard, they will eat all the pollinators and crop around and there will often not be enough insects left that could pollinate your crops.By installing a scarecrow in your yard, you can mitigate this problem since it will keep away birds and other animals to a certain extent and therefore, insect populations will likely increase significantly, which can have a positive impact on the growth behavior of your plants as well as your yields in genera
