I think that you should change this ASAP, preferably today. You should not be applying ED to a school that you do not want to attend.
You are a competitive applicant anywhere. Yes Stanford is a reach. However, your stats are competitive there. They will look at your SAT, which is superb.
Also, Johns Hopkins is a very long way to go for someone who lives in California, and is a very long way to go for someone who does not really want to go there, and is likely to be expensive particularly for someone who is in-state for the many excellent Universities of California and Cal State Universities.
Then absolutely positively do not apply ED to a school on the other side of the country. Yes Johns Hopkins is a very good university. However, it does not seem like there is any reason for you to apply there ED, or for you to go there at all.
To me, your post seems to suggest that you should not ED anywhere. You do not need to apply ED anywhere. In my family no one applied ED anywhere. We still got accepted to some very good universities. Perhaps more importantly, for at least my two daughters both got their bachelor’s degrees at schools that were a very good fit for them, and then got accepted to graduate programs that were a very good fit for them and were highly ranked for their particular majors.
And environmental science is a field where some form of graduate program is at least a realistic possibility, and you can get into highly ranked graduate programs (on the level of Stanford or HYP) with a degree from any school on your list, or for example any of the UCs.
Which brings me to the most important point: Fit is way, way more important than rankings. You should be looking for a school that is a good fit for you. If you want to stay close to home, then this will not be a school that is on the other side of the USA (such as JHU, Columbia, or HYP or Duke).
I am a bit biased. I got my master’s degree at Stanford and loved it. It is a high reach for pretty much everyone. However, I do think that you have a chance there. I think that your stats are good enough to get you solidly into the “academically qualified” group (which is still 80% of applicants for a school with a 4% acceptance rate), and then they will look at your ECs, essays, and letters of reference, all of which will be very important and look to be very good in your case.
If you right away change your ED to an EA or RD, then you have a good list of schools that you have applied to. UC Santa Barbara is a very good university. UC Davis is a very good university. The other UCs are also very good (ALL of them, including Riverside and Merced). You might want to think about whether to add one or two of the Cal States. I agree with another comment above that Colorado State is worth looking at (it is probably a safety and is likely to be very affordable since it is a WICHE/WUE school, one small nit there is that it has a superb and highly ranked DVM program and there will be some very, very strong pre-vet students there, some of whom would be in some of your classes and might be interesting to meet).
So change your ED to EA or RD, make sure that you have applied to at least two safeties, look for a good fit, and ignore rankings. With this I think that you are likely to do very well.
And I do not think that anyone who is really horrid at mathematics would have gotten at least 770 on the math part of the SAT!
