Question: have you found anything useful in your investigation

Yes, as my project is the only one in the world it has been a huge relief that we have found some very interesting things. We have found that under future climatic conditions (50 years in the future), the oak leaves change their nutrient levels (specifically their nitrogen to carbon ratios in the leaf). As insects (herbivores) want the nitrogen in the leaf it means they have to eat more of the leaf to get to the nitrogen. This means that in the future, insects might be eating more of our leaves! Another time we have found is that soil nutrients decrease (nitrogen and phosphorus). This is not good for plant growth as they need these nutrients to grow big and strong. It might also mean that we have to add more fertilisers to our crops in the future.
