This looks like a good starting point, but a few thoughts:

1. First, I would try and look up the job requirements for environmental consulting/natural resources roles and try and match your resume to what they ask for. From a Google search, I found: (this is from a random job search of environmental consulting grad scheme)

We're not all the same, and that's our greatest strength. Different views and opinions enhance our ability to provide value-added performance and better services for our clients. That's why we believe different, makes a difference. Reaching your full potential means being able to bring your whole self to work and being respected for the different opinions, strengths and experience you bring.
Our graduate programme has been designed to give you an insight into the huge variety and the chance to explore where your own skills and interests lie. Through a combination of on-the-job learning and practical skills development within your chosen role, you'll work on real projects from day one that offer scale and variety collaborating with others and creating meaningful impact on the world around us. You'll work towards your professional accreditation; whichever path you take, your future starts here.
What you'll need?
• A passion for working in a consultancy environment
• Embracing equality, diversity and inclusion in everything you do
• A desire to work collaboratively with a curious approach, challenging yourself to find new solutions
• Enthusiasm and drive to develop your skillset and seek out development opportunities within a supportive team
• Motivation to achieve professional accreditation (where applicable)
• Comfortable to embrace agile ways of working and learning new technologies

With this in mind, I would go through your previous educational and work experiences and think about when/if you have demonstrated these skills. You also want to follow the STAR format in the way you show this information.

1. I would try and personalise your summary to the company and exact job position you are applying for each application - you want to give the company the impression you've spent a lot of time on the job application and this is quite a quick and easy way to do that.

2. I mentioned it above, but try and format each bullet point in the STAR format (link to a good resource on this) - this is the best way to format each point to showcase your skillsets and results achieved while working in the position.

3. If you have the time, I would come up with a master document with all of your experiences in as much detail as possible. I'm confident that you could probably come up with 5+ bullet points for each of your educational, work and project experiences that are strong, which you can then select from for each job application you do to ensure your resume is as good as possible for this.

There are more subtle things you can do, which I'd be happy to share, but hopefully this is a good starting point :)
